A popular name for a sharp pain in the side. It is generally due to cramp (see MUSCLES, DISORDERS OF) following unusually hard exertion, but care must be taken that this trivial condition is not taken for PLEURISY or for a fractured rib. The word is also used to mean the repair of skin following surgery or any other trauma.

Catgut

A traditional absorbable SUTURE used in surgery for tying cut arteries and stitching wounds. Consisting of twisted COLLAGEN (from sheep or cattle intestines), catgut is absorbed by phagocytes (see under PHAGOCYTE) over a variable period. There are two types: plain, and chromatised or chromic. Synthetic absorbable sutures cause less reaction, have a predictable absorption period and are more e?ective.... catgut

Elecampane

Inula helenium. N.O. Compositae.

Synonym: Aunee, Scabwort.

Habitat: Moist meadows and pasture land.

Features ? The stem. growing up to three feet, is branched, furrowed, and downy above; egg-shaped, serrate leaves embrace the stem. The calyx is also egg-shaped and leafy, and the flowers, blooming in July and August, are large, solitary and terminal, brilliantly yellow in colour. The root is light grey, hard, horny and cylindrical. The whole plant is similar in appearance to the horseradish, its taste is bitter and acrid, and the odour reminiscent of camphor.

Part used ? Root.

Action: Diaphoretic, expectorant and diuretic.

In combination with other remedies it is made up into cough medicines, and can be of service in pulmonary disorders generally. Skillfully compounded, slight alterative and tonic qualities are noticed. Wineglass doses are taken of a 1 ounce to 1 pint (reduced) decoction.

These modest present-day claims for Elecampane are far exceeded by Culpeper's exuberance. In his view, the root "warms a cold and windy stomach or the pricking therein, and stitches in the side caused by the spleen; helps the cough, shortness of the breath, and wheezing of the lungs. . . . Profitable for those that have their urine stopped. . . . Resisteth poison, and stayeth the venom of serpents, as also of putrid and pestilential fevers, and the plague itself." When we are also told by the same author that it kills and expels worms, fastens loose teeth, arrests dental decay, cleanses the skin from morphew, spots and blemishes, we realize in what esteem Elecampane was held in the seventeenth century! But here again germs of truth are hidden among manifold exaggerations.... elecampane

Suture

A word used in both an anatomical and a surgical sense. (1) Anatomically, suture is a type of immovable joint, found particularly in the SKULL, including the coronal suture (between the frontal and parietal bones); the lamboidal suture (between the parietal and occipital bones); and the sagittal suture (between the two parietal bones). (2) Surgically the word refers either to the technique of closing a wound, or to the material used. Stitching methods have been developed for gastrointestinal, neurological, dermatological and other forms of surgery, and include laser surgery and removable clips or staples. The material used is generally divided into mono?lament, twisted or braided. Absorbable sutures – used for internal stitching

– include catgut, Vicryl® and Dexon®. Nonabsorbable sutures include silk, nylon and prolene. The type used and time of suture-removal depend upon the site and general state of the patient. Those patients on steroids who have a malignant or infective disorder heal slowly, and their sutures may need to stay in for 14 days or more instead of the usual 5–8 days.... suture

Gastroenterostomy

An operation performed usually in order to relieve some obstruction to the outlet from the STOMACH. One opening is made in the lower part of the stomach; another in a neighbouring loop of the small intestine. The two are then stitched together.... gastroenterostomy

Intussusception

A form of obstruction of the bowels in which part of the INTESTINE enters within that part immediately beneath it. This can best be understood by observing what takes place in the ?ngers of a tightly ?tting glove as they turn outside-in when the glove is pulled o? the hand. Mostly, the condition affects infants. Often it occurs during the course of a viral infection or a mild attack of gastroenteritis, or it may be that swelling of lymphoid tissue in the gut provokes the event. The point at which it most often occurs is the junction between the small and the large intestines, the former passing within the latter. The symptoms are those of intestinal obstruction in general (see INTESTINE, DISEASES OF – Obstruction), and in addition there is often a discharge of blood-stained mucus from the bowel. Unless the symptoms rapidly subside, when it may be assumed that the bowel has righted itself, treatment consists of either hydrostatic reduction by means of a barium or air ENEMA, or an operation. At operation the intussusception is either reduced or, if this not possible, the obstructed part is cut out and the ends of the intestine then stitched together. If treated adequately and in time, the mortality is now reduced to around 1 per cent. The condition may recur in about 5 per cent of patients.... intussusception

Herb Pillow

To promote sleep. Fill linen bag with herbs: Hops, Chamomile, Bergamot, Basil, etc. Stitch together ends. Expose to heat before use. ... herb pillow

Cervical Incompetence

Abnormal weakness of the cervix that can result in recurrent miscarriages. An incompetent cervix may gradually widen under the weight of the fetus from about the 12th week of pregnancy onwards, or may suddenly open during the second trimester. The condition is detected by an internal examination or by ultrasound scanning.

Treatment is with a suture (stitch) applied like a purse string around the cervix during the 4th month of pregnancy. The suture is left in position until the pregnancy is at or near full term and is then cut to allow the mother to deliver the baby normally.... cervical incompetence

Episiotomy

A surgical procedure in which an incision is made in the perineum (the tissue between the vagina and the anus) to facilitate the delivery of a baby. After delivery, the cut tissues are stitched back together. Episiotomy is usually necessary in a forceps delivery and in a breech delivery.... episiotomy

Face-lift

A cosmetic operation to smooth out wrinkles and lift sagging skin on an aging face. The effect is achieved by lifting the skin off the face and removing the excess. The skin is then stitched back together within the hairline. The effect usually lasts about 5 years. ... face-lift

Intestine, Diseases Of

The principal signs of trouble which has its origin in the intestine consist of pain somewhere about the abdomen, sometimes vomiting, and irregular bowel movements: constipation, diarrhoea or alternating bouts of these.

Several diseases and conditions are treated under separate headings. (See APPENDICITIS; CHOLERA; COLITIS; CONSTIPATION; CROHN’S DISEASE; DIARRHOEA; DYSENTERY; ENTERIC FEVER; HAEMORRHOIDS; HERNIA; INFLAMMATORY BOWEL DISEASE (IBD); ILEITIS; INTUSSUSCEPTION; IRRITABLE BOWEL SYNDROME (IBS); PERITONITIS; RECTUM, DISEASES OF; ULCERATIVE COLITIS.)

In?ammation of the outer surface is called peritonitis, a serious disease. That of the inner surface is known generally as enteritis, in?ammation of special parts receiving the names of colitis, appendicitis, irritable bowel syndrome (IBS) and in?ammatory bowel disease (IBD). Enteritis may form the chief symptom of certain infective diseases: for example in typhoid fever (see ENTERIC FEVER), cholera and dysentery. It may be acute, although not connected with any de?nite organism, when, if severe, it is a very serious condition, particularly in young children. Or it may be chronic, especially as the result of dysentery, and then constitutes a less serious if very troublesome complaint.

Perforation of the bowel may take place as the result either of injury or of disease. Stabs and other wounds which penetrate the abdomen may damage the bowel, and severe blows or crushes may tear it without any external wound. Ulceration, as in typhoid fever, or, more rarely, in TUBERCULOSIS, may cause an opening in the bowel-wall also. Again, when the bowel is greatly distended above an obstruction, faecal material may accumulate and produce ulcers, which rupture with the ordinary movements of the bowels. Whatever the cause, the symptoms are much the same.

Symptoms The contents of the bowel pass out through the perforation into the peritoneal cavity, and set up a general peritonitis. In consequence, the abdomen is painful, and after a few hours becomes extremely tender to the touch. The abdomen swells, particularly in its upper part, owing to gas having passed also into the cavity. Fever and vomiting develop and the person passes into a state of circulatory collapse or SHOCK. Such a condition may be fatal if not properly treated.

Treatment All food should be withheld and the patient given intravenous ?uids to resuscitate them and then to maintain their hydration and electrolyte balance. An operation is urgently necessary, the abdomen being opened in the middle line, the perforated portion of bowel found, the perforation stitched up, and appropriate antibiotics given.

Obstruction means a stoppage to the passage down the intestine of partially digested food. Obstruction may be acute, when it comes on suddenly with intense symptoms; or it may be chronic, when the obstructing cause gradually increases and the bowel becomes slowly more narrow until it closes altogether; or subacute, when obstruction comes and goes until it ends in an acute attack. In chronic cases the symptoms are milder in degree and more prolonged.

Causes Obstruction may be due to causes outside the bowel altogether, for example, the pressure of tumours in neighbouring organs, the twisting around the bowel of bands produced by former peritonitis, or even the twisting of a coil of intestine around itself so as to cause a kink in its wall. Chronic causes of the obstruction may exist in the wall of the bowel itself: for example, a tumour, or the contracting scar of an old ulcer. The condition of INTUSSUSCEPTION, where part of the bowel passes inside of the part beneath it, in the same way as one turns the ?nger of a glove outside in, causes obstruction and other symptoms. Bowel within a hernia may become obstructed when the hernia strangulates. Finally some body, such as a concretion, or the stone of some large fruit, or even a mass of hardened faeces, may become jammed within the bowel and stop up its passage.

Symptoms There are four chief symptoms: pain, vomiting, constipation and swelling of the abdomen.

Treatment As a rule the surgeon opens the abdomen, ?nds the obstruction and relieves it or if possible removes it altogether. It may be necessary to form a COLOSTOMY or ILEOSTOMY as a temporary or permanent measure in severe cases.

Tumours are rare in the small intestine and usually benign. They are relatively common in the large intestine and are usually cancerous. The most common site is the rectum. Cancer of the intestine is a disease of older people; it is the second most common cancer (after breast cancer) in women in the United Kingdom, and the third most common (after lung and prostate) in men. Around 25,000 cases of cancer of the large intestine occur in the UK annually, about 65 per cent of which are in the colon. A history of altered bowel habit, in the form of increasing constipation or diarrhoea, or an alternation of these, or of bleeding from the anus, in a middle-aged person is an indication for taking medical advice. If the condition is cancer, then the sooner it is investigated and treated, the better the result.... intestine, diseases of

Pregnancy And Labour

Pregnancy The time when a woman carries a developing baby in her UTERUS. For the ?rst 12 weeks (the ?rst trimester) the baby is known as an EMBRYO, after which it is referred to as the FETUS.

Pregnancy lasts about 280 days and is calculated from the ?rst day of the last menstrual period – see MENSTRUATION. Pregnancy-testing kits rely on the presence of the hormone beta HUMAN CHORIONIC GONADOTROPHIN (b HCG) which is excreted in the woman’s urine as early as 30 days from the last menstrual period. The estimated date of delivery can be accurately estimated from the size of the developing fetus measured by ULTRASOUND (see also below) between seven and 24 weeks. ‘Term’ refers to the time that the baby is due; this can range from 38 weeks to 41 completed weeks.

Physical changes occur in early pregnancy – periods stop and the abdomen enlarges. The breasts swell, with the veins becoming prominent and the nipples darkening. About two in three women will have nausea with a few experiencing such severe vomiting as to require hospital admission for rehydration.

Antenatal care The aim of antenatal care is to ensure a safe outcome for both mother and child; it is provided by midwives (see MIDWIFE) and doctors. Formal antenatal care began in Edinburgh in the 1930s with the recognition that all aspects of pregnancy – normal and abnormal – warranted surveillance. Cooperation between general practitioners, midwives and obstetricians is now established, with pregnancies that are likely to progress normally being cared for in the community and only those needing special intervention being cared for in a hospital setting.

The initial visit (or booking) in the ?rst half of pregnancy will record the history of past events and the results of tests, with the aim of categorising the patients into normal or not. Screening tests including blood checks and ultrasound scans are a routine part of antenatal care. The ?rst ultrasound scan is done at about 11 weeks to date the pregnancy, with a further one done at 20 weeks – the anomaly scan – to assess the baby’s structure. Some obstetric units will check the growth of the baby with one further scan later in the pregnancy or, in the case of twin pregnancies (see below), many scans throughout. The routine blood tests include checks for ANAEMIA, DIABETES MELLITUS, sickle-cell disease and THALASSAEMIA, as well as for the blood group. Evidence of past infections is also looked for; tests for RUBELLA (German measles) and SYPHILIS are routine, whereas tests for human immunode?ciency virus (see AIDS/ HIV below) and HEPATITIS are being o?ered as optional, although there is compelling evidence that knowledge of the mother’s infection status is bene?cial to the baby.

Traditional antenatal care consists of regular appointments, initially every four weeks until 34 weeks, then fortnightly or weekly. At each visit the mother’s weight, urine and blood pressure are checked, and assessment of fetal growth and position is done by palpating the uterus. Around two-thirds of pregnancies and labours are normal: in the remainder, doctors and midwives need to increase the frequency of surveillance so as to prevent or deal with maternal and fetal problems.

Common complications of pregnancy

Some of the more common complications of pregnancy are listed below.

As well as early detection of medical complications, antenatal visits aim to be supportive and include emotional and educational care. Women with uncomplicated pregnancies are increasingly being managed by midwives and general practitioners in the community and only coming to the hospital doctors should they develop a problem. A small number will opt for a home delivery, but facilities for providing such a service are not always available in the UK.

Women requiring more intensive surveillance have their management targeted to the speci?c problems encountered. Cardiologists will see mothers-to-be with heart conditions, and those at risk of diabetes are cared for in designated clinics with specialist sta?. Those women needing more frequent surveillance than standard antenatal care can be looked after in maternity day centres. These typically include women with mildly raised blood pressure or those with small babies. Fetal medicine units have specialists who are highly skilled in ultrasound scanning and specialise in the diagnosis and management of abnormal babies still in the uterus. ECTOPIC PREGNANCY Chronic abdominal discomfort early in pregnancy may be caused by unruptured ectopic pregnancy, when, rarely, the fertilised OVUM starts developing in the Fallopian tube (see FALLOPIAN TUBES) instead of the uterus. The patient needs hospital treatment and LAPAROSCOPY. A ruptured ectopic pregnancy causes acute abdominal symptoms and collapse, and the woman will require urgent abdominal surgery. URINARY TRACT INFECTIONS These affect around 2 per cent of pregnant women and are detected by a laboratory test of a mid-stream specimen of urine. In pregnancy, symptoms of these infections do not necessarily resemble those experienced by non-pregnant women. As they can cause uterine irritability and possible premature labour (see below), it is important to ?nd and treat them appropriately. ANAEMIA is more prevalent in patients who are vegetarian or on a poor diet. Iron supplements are usually given to women who have low concentrations of HAEMOGLOBIN in their blood (less than 10.5 g/dl) or who are at risk of becoming low in iron, from bleeding, twin pregnancies and those with placenta previa (see below). ANTEPARTUM HAEMORRHAGE Early in pregnancy, vaginal bleedings may be due to a spontaneous or an incomplete therapeutic ABORTION. Bleeding from the genital tract between 24 completed weeks of pregnancy and the start of labour is called antepartum haemorrhage. The most common site is where the PLACENTA is attached to the wall of the uterus. If the placenta separates before delivery, bleeding occurs in the exposed ‘bed’. When the placenta is positioned in the upper part of the uterus it is called an abruption. PLACENTA PRAEVIA is sited in the lower part and blocks or partly blocks the cervix (neck of the womb); it can be identi?ed at about the 34th week. Ten per cent of episodes of antepartum bleeding are caused by placenta previa, and it may be associated with bleeding at delivery. This potentially serious complication is diagnosed by ultrasound scanning and may require a caesarean section (see below) at delivery. INCREASED BLOOD PRESSURE, associated with protein in the urine and swelling of the limbs, is part of a condition known as PRE-ECLAMPSIA. This occurs in the second half of pregnancy in about 1 in 10 women expecting their ?rst baby, and is mostly very mild and of no consequence to the pregnancy. However, some women can develop extremely high blood pressures which can adversely affect the fetus and cause epileptic-type seizures and bleeding disorders in the mother. This serious condition is called ECLAMPSIA. For this reason a pregnant woman with raised blood pressure or PROTEIN in her urine is carefully evaluated with blood tests, often in the maternity day assessment unit. The condition can be stopped by delivery of the baby, and this will be done if the mother’s or the fetus’s life is in danger. If the condition is milder, and the baby not mature enough for a safe delivery, then drugs can be used to control the blood pressure. MISCARRIAGE Also called spontaneous abortion, miscarriage is the loss of the fetus. There are several types:

threatened miscarriage is one in which some vaginal bleeding occurs, the uterus is enlarged, but the cervix remains closed and pregnancy usually proceeds.

inevitable miscarriage usually occurs before the 16th week and is typi?ed by extensive blood loss through an opened cervix and cramp-like abdominal pain; some products of conception are lost but the developing placental area (decidua) is retained and an operation may be necessary to clear the womb.

missed miscarriages, in which the embryo dies and is absorbed, but the decidua (placental area of uterine wall) remains and may cause abdominal discomfort and discharge of old blood.

THERAPEUTIC ABORTION is performed on more than 170,000 women annually in England and Wales. Sometimes the woman may not have arranged the procedure through the usual health-care channels, so that a doctor may see a patient with vaginal bleeding, abdominal discomfort or pain, and open cervix – symptoms which suggest that the decidua and a blood clot have been retained; these retained products will need to be removed by curettage.

Septic abortions are now much less common in Britain than before the Abortion Act (1967) permitted abortion in speci?ed circumstances. The cause is the passage of infective organisms from the vagina into the uterus, with Escherichia coli and Streptococcus faecalis the most common pathogenic agents. The woman has abdominal pain, heavy bleeding, usually fever and sometimes she is in shock. The cause is usually an incomplete abortion or one induced in unsterile circumstances. Antibiotics and curettage are the treatment. INTRAUTERINE GROWTH RETARDATION describes a slowing of the baby’s growth. This can be diagnosed by ultrasound scanning, although there is a considerable margin of error in estimates of fetal weight. Trends in growth are favoured over one-o? scan results alone. GESTATIONAL DIABETES is a condition that is more common in women who are overweight or have a family member with diabetes. If high concentrations of blood sugar are found, e?orts are made to correct it as the babies can become very fat (macrosomia), making delivery more di?cult. A low-sugar diet is usually enough to control the blood concentration of sugars; however some women need small doses of INSULIN to achieve control. FETAL ABNORMALITIES can be detected before birth using ultrasound. Some of these defects are obvious, such as the absence of kidneys, a condition incompatible with life outside the womb. These women can be o?ered a termination of their pregnancy. However, more commonly, the pattern of problems can only hint at an abnormality and closer examination is needed, particularly in the diagnosis of chromosomal deformities such as DOWN’S (DOWN) SYNDROME (trisomy 21 or presence of three 21 chromosomes instead of two).

Chromosomal abnormalities can be de?nitively diagnosed only by cell sampling such as amniocentesis (obtaining amniotic ?uid – see AMNION – from around the baby) done at 15 weeks onwards, and chorionic villus sampling (sampling a small part of the placenta) – another technique which can be done from 12 weeks onwards. Both have a small risk of miscarriage associated with them; consequently, they are con?ned to women at higher risk of having an abnormal fetus.

Biochemical markers present in the pregnant woman’s blood at di?erent stages of pregnancy may have undergone changes in those carrying an abnormal fetus. The ?rst such marker to be routinely used was a high concentration of alpha-fetol protein in babies with SPINA BIFIDA (defects in the covering of the spinal cord). Fuller research has identi?ed a range of diagnostic markers which are useful, and, in conjunction with other factors such as age, ethnic group and ultrasound ?ndings, can provide a predictive guide to the obstetrician – in consultation with the woman – as to whether or not to proceed to an invasive test. These tests include pregnancy-associated plasma protein assessed from a blood sample taken at 12 weeks and four blood tests at 15–22 weeks – alphafetol protein, beta human chorionic gonadotrophin, unconjugated oestriol and inhibin A. Ultrasound itself can reveal physical ?ndings in the fetus, which can be more common in certain abnormalities. Swelling in the neck region of an embryo in early pregnancy (increased nuchal thickness) has good predictive value on its own, although its accuracy is improved in combination with the biochemical markers. The e?ectiveness of prenatal diagnosis is rapidly evolving, the aim being to make the diagnosis as early in the pregnancy as possible to help the parents make more informed choices. MULTIPLE PREGNANCIES In the UK, one in 95 deliveries is of twins, while the prevalence of triplets is one in 10,000 and quadruplets around one in 500,000. Racial variations occur, with African women having a prevalence rate of one in 30 deliveries for twins and Japanese women a much lower rate than the UK ?gure. Multiple pregnancies occur more often in older women, and in the UK the prevalence of fertility treatments, many of these being given to older women, has raised the incidence. There is now an o?cial limit of three eggs being transferred to a woman undergoing ASSISTED CONCEPTION (gamete intrafallopian transfer, or GIFT).

Multiple pregnancies are now usually diagnosed as a result of routine ultrasound scans between 16 and 20 weeks of pregnancy. The increased size of the uterus results in the mother having more or worse pregnancy-related conditions such as nausea, abdominal discomfort, backache and varicose veins. Some congenital abnormalities in the fetus occur more frequently in twins: NEURAL TUBE defects, abnormalities of the heart and the incidence of TURNER’S SYNDROME and KLINEFELTER’S SYNDROME are examples. Such abnormalities may be detected by ultrasound scans or amniocentesis. High maternal blood pressure and anaemia are commoner in women with multiple pregnancies (see above).

The growth rates of multiple fetuses vary, but the di?erence between them and single fetuses are not that great until the later stages of pregnancy. Preterm labour is commoner in multiple pregnancies: the median length of pregnancy is 40 weeks for singletons, 37 for twins and 33 for triplets. Low birth-weights are usually the result of early delivery rather than abnormalities in growth rates. Women with multiple pregnancies require more frequent and vigilant antenatal assessments, with their carers being alert to the signs of preterm labour occurring. CEPHALOPELVIC DISPROPORTION Disparity between the size of the fetus and the mother’s pelvis is not common in the UK but is a signi?cant problem in the developing world. Disparity is classi?ed as absolute, when there is no possibility of delivery, and relative, when the baby is large but delivery (usually after a dif?cult labour) is possible. Causes of absolute disparity include: a large baby – heavier than 5 kg at birth; fetal HYDROCEPHALUS; and an abnormal maternal pelvis. The latter may be congenital, the result of trauma or a contraction in pelvic size because of OSTEOMALACIA early in life. Disproportion should be suspected if in late pregnancy the fetal head has not ‘engaged’ in the pelvis. Sometimes a closely supervised ‘trial of labour’ may result in a successful, if prolonged, delivery. Otherwise a caesarean section (see below) is necessary. UNUSUAL POSITIONS AND PRESENTATIONS OF THE BABY In most pregnant women the baby ?ts into the maternal pelvis head-?rst in what is called the occipito-anterior position, with the baby’s face pointing towards the back of the pelvis. Sometimes, however, the head may face the other way, or enter the pelvis transversely – or, rarely, the baby’s neck is ?exed backwards with the brow or face presenting to the neck of the womb. Some malpositions will correct naturally; others can be manipulated abdominally during pregnancy to a better position. If, however, the mother starts labour with the baby’s head badly positioned or with the buttocks instead of the head presenting (breech position), the labour will usually be longer and more di?cult and may require intervention using special obstetric forceps to assist in extracting the baby. If progress is poor and the fetus distressed, caesarean section may be necessary. HIV INFECTION Pregnant women who are HIV positive (see HIV; AIDS/HIV) should be taking antiviral drugs in the ?nal four to ?ve months of pregnancy, so as to reduce the risk of infecting the baby in utero and during birth by around 50 per cent. Additional antiviral treatment is given before delivery; the infection risk to the baby can be further reduced – by about 40 per cent – if delivery is by caesarean section. The mother may prefer to have the baby normally, in which case great care should be taken not to damage the baby’s skin during delivery. The infection risk to the baby is even further reduced if it is not breast fed. If all preventive precautions are taken, the overall risk of the infant becoming infected is cut to under 5 per cent.

Premature birth This is a birth that takes place before the end of the normal period of gestation, usually before 37 weeks. In practice, however, it is de?ned as a birth that takes place when the baby weighs less than 2·5 kilograms (5••• pounds). Between 5 and 10 per cent of babies are born prematurely, and in around 40 per cent of premature births the cause is unknown. Pre-eclampsia is the most common known cause; others include hypertension, chronic kidney disease, heart disease and diabetes mellitus. Multiple pregnancy is another cause. In the vast majority of cases the aim of management is to prolong the pregnancy and so improve the outlook for the unborn child. This consists essentially of rest in bed and sedation, but there are now several drugs, such as RITODRINE, that may be used to suppress the activity of the uterus and so help to delay premature labour. Prematurity was once a prime cause of infant mortality but modern medical care has greatly improved survival rates in developing countries.

Labour Also known by the traditional terms parturition, childbirth or delivery, this is the process by which the baby and subsequently the placenta are expelled from the mother’s body. The onset of labour is often preceded by a ‘show’ – the loss of the mucus and blood plug from the cervix, or neck of the womb; this passes down the vagina to the exterior. The time before the beginning of labour is called the ‘latent phase’ and characteristically lasts 24 hours or more in a ?rst pregnancy. Labour itself is de?ned by regular, painful contractions which cause dilation of the neck of the womb and descent of the fetal head. ‘Breaking of the waters’ is the loss of amniotic ?uid vaginally and can occur any time in the delivery process.

Labour itself is divided into three stages: the ?rst is from the onset of labour to full (10 cm) dilation of the neck of the womb. This stage varies in length, ideally taking no more than one hour per centimetre of dilation. Progress is monitored by regular vaginal examinations, usually every four hours. Fetal well-being is observed by intermittent or continuous monitoring of the fetal heart rate in relation to the timing and frequency of the contractions. The print-out is called a cardiotocograph. Abnormalities of the fetal heart rate may suggest fetal distress and may warrant intervention. In women having their ?rst baby (primigravidae), the common cause of a slow labour is uncoordinated contractions which can be overcome by giving either of the drugs PROSTAGLANDIN or OXYTOCIN, which provoke contractions of the uterine muscle, by an intravenous drip. Labours which progress slowly or not at all may be due to abnormal positioning of the fetus or too large a fetus, when prostaglandin or oxytocin is used much more cautiously.

The second stage of labour is from full cervical dilation to the delivery of the baby. At this stage the mother often experiences an irresistible urge to push the baby out, and a combination of strong coordinated uterine contractions and maternal e?ort gradually moves the baby down the birth canal. This stage usually lasts under an hour but can take longer. Delay, exhaustion of the mother or distress of the fetus may necessitate intervention by the midwife or doctor. This may mean enlarging the vaginal opening with an EPISIOTOMY (cutting of the perineal outlet – see below) or assisting the delivery with specially designed obstetric forceps or a vacuum extractor (ventouse). If the cervix is not completely dilated or open and the head not descended, then an emergency caesarean section may need to be done to deliver the baby. This procedure involves delivering the baby and placenta through an incision in the mother’s abdomen. It is sometimes necessary to deliver by planned or elective caesarean section: for example, if the placenta is low in the uterus – called placenta praevia – making a vaginal delivery dangerous.

The third stage occurs when the placenta (or afterbirth) is delivered, which is usually about 10–20 minutes after the baby. An injection of ergometrine and oxytocin is often given to women to prevent bleeding.

Pain relief in labour varies according to the mother’s needs. For uncomplicated labours, massage, reassurance by a birth attendant, and a warm bath and mobilisation may be enough for some women. However, some labours are painful, particularly if the woman is tired or anxious or is having her ?rst baby. In these cases other forms of analgesia are available, ranging from inhalation of NITROUS OXIDE GAS, injection of PETHIDINE HYDROCHLORIDE or similar narcotic, and regional local anaesthetic (see ANAESTHESIA).

Once a woman has delivered, care continues to ensure her and the baby’s safety. The midwives are involved in checking that the uterus returns to its normal size and that there is no infection or heavy bleeding, as well as caring for stitches if needed. The normal blood loss after birth is called lochia and generally is light, lasting up to six weeks. Midwives o?er support with breast feeding and care of the infant and will visit the parents at home routinely for up to two weeks.

Some complications of labour All operative deliveries in the UK are now done in hospitals, and are performed if a spontaneous birth is expected to pose a bigger risk to the mother or her child than a specialist-assisted one. Operative deliveries include caesarean section, forceps-assisted deliveries and those in which vacuum extraction (ventouse) is used. CAESAREAN SECTION Absolute indications for this procedure, which is used to deliver over 15 per cent of babies in Britain, are cephalopelvic disproportion and extensive placenta praevia, both discussed above. Otherwise the decision to undertake caesarean section depends on the clinical judgement of the specialist and the views of the mother. The rise in the proportion of this type of intervention (from 5 per cent in the 1930s to its present level of over 23 per cent

P

of the 600,000 or so annual deliveries in England) has been put down to defensive medicine

– namely, the doctor’s fear of litigation (initiated often because the parents believe that the baby’s health has suffered because the mother had an avoidably di?cult ‘natural’ labour). In Britain, over 60 per cent of women who have had a caesarean section try a vaginal delivery in a succeeding pregnancy, with about two-thirds of these being successful. Indications for the operation include:

absolute and relative cephalopelvic disproportion.

placenta previa.

fetal distress.

prolapsed umbilical cord – this endangers the viability of the fetus because the vital supply of oxygen and nutrients is interrupted.

malpresentation of the fetus such as breech or transverse lie in the womb.

unsatisfactory previous pregnancies or deliveries.

a request from the mother.

Caesarean sections are usually performed using regional block anaesthesia induced by a spinal or epidural injection. This results in loss of feeling in the lower part of the body; the mother is conscious and the baby not exposed to potential risks from volatile anaesthetic gases inhaled by the mother during general anaesthesia. Post-operative complications are higher with general anaesthesia, but maternal anxiety and the likelihood that the operation might be complicated and di?cult are indications for using it. A general anaesthetic may also be required for an acute obstetric emergency. At operation the mother’s lower abdomen is opened and then her uterus opened slowly with a transverse incision and the baby carefully extracted. A transverse incision is used in preference to the traditional vertical one as it enables the woman to have a vaginal delivery in any future pregnancy with a much smaller risk of uterine rupture. Women are usually allowed to get up within 24 hours and are discharged after four or ?ve days. FORCEPS AND VENTOUSE DELIVERIES Obstetric forceps are made in several forms, but all are basically a pair of curved blades shaped so that they can obtain a purchase on the baby’s head, thus enabling the operator to apply traction and (usually) speed up delivery. (Sometimes they are used to slow down progress of the head.) A ventouse or vacuum extractor comprises an egg-cup-shaped metal or plastic head, ranging from 40 to 60 mm in diameter with a hollow tube attached through which air is extracted by a foot-operated vacuum pump. The instrument is placed on the descending head, creating a negative pressure on the skin of the scalp and enabling the operator to pull the head down. In mainland Europe, vacuum extraction is generally preferred to forceps for assisting natural deliveries, being used in around 5 per cent of all deliveries. Forceps have a greater risk of causing damage to the baby’s scalp and brain than vacuum extraction, although properly used, both types should not cause any serious damage to the baby.

Episiotomy Normal and assisted deliveries put the tissues of the genital tract under strain. The PERINEUM is less elastic than the vagina and, if it seems to be splitting as the baby’s head

moves down the birth canal, it may be necessary to cut the perineal tissue – a procedure called an episiotomy – to limit damage. This is a simple operation done under local anaesthetic. It should be done only if there is a speci?c indication; these include:

to hasten the second stage of labour if the fetus is distressed.

to facilitate the use of forceps or vacuum extractor.

to enlarge a perineum that is restricted because of unyielding tissue, perhaps because of a scar from a previous labour. Midwives as well as obstetricians are trained

to undertake and repair (with sutures) episiotomies.

Suturing

The closing of a surgical incision or a wound by sutures (stitches) to promote healing.

This may be done by means of a single stitch under the skin (subcuticular) or by using individual stitches (interrupted).

Some materials used in suturing, such as catgut, eventually dissolve in the body; skin sutures made of other materials are removed about 1–2 weeks after insertion.... suturing

Tattooing

The introduction of permanent colours under the skin surface, usually to create a picture.

Small tattoos can be removed by cutting out the tattoo and stitching the wound edges together.

Larger tattoos can sometimes be removed by dermabrasion or by laser treatment.... tattooing

Wild Carrot

Daucus carota. N.O. Umbelliferae.

Synonym: Bird's Nest.

Habitat: Wastes, pastures and field borders.

Features ? The branched stems of one to three feet high are tough and bristly. The whole plant is hairy, and the leaves are oblong and bipinnate, with acute segments. Blossoming in June and July, the umbel of white flowers usually contains one crimson flower in the centre. The root tapers, is yellowish-white, sweetish, and faintly aromatic. Wren tells us that "in taste and odour it resembles the garden carrot, but the root is small and white, not large." Ferrier, however, says of this root, "no resemblance in taste or colour to the cultivated carrot." Our own opinion is that Wild Carrot tastes like a rather distant relative of the household carrot—which it probably is.

Part used ? The whole plant.

Action: Pronouncedly diuretic in action, as well as de-obstruent and stimulant.

Wild Carrot naturally, therefore, takes a prominent place in many formulae for the treatment of dropsy, gravel, retention of urine, and bladder trouble generally. Either an infusion or decoction may be prepared in the usual proportions, and doses of 2 fl. ounces taken three or four times daily.

Culpeper comments ? "Wild Carrots belong to Mercury, and therefore breaketh wind, and removeth stitches in the sides, provoketh urine and women's courses, and helpeth to break and expel the stone."... wild carrot

First Aid And Medicine Chest

Various aspects of first aid are described under the following: ABRASIONS, BLEEDING, CUTS, SHOCK, EYES, FAINTING, FRACTURES, INJURIES, POISONING, WOUNDS, WITCH HAZEL.

Avoid overstocking; some herbs lose their potency on the shelf in time, especially if exposed. Do not keep on a high shelf out of the way. Experts suggest a large box with a lid to protect its contents, kept in a cool dry place away from foods and other household items. Store mixtures containing Camphor separately elsewhere. Camphor is well-known as a strong antidote to medicinal substances. Keep all home-made ointments in a refrigerator. However harmless, keep all remedies out of reach of children. Be sure that all tablet containers have child-resistant tops.

Keep a separate box, with duplicates, permanently in the car. Check periodically. Replace all tablets when crumbled, medicines with changed colour or consistency. Always carry a large plastic bottle of water in the car for cleansing dirty wounds and to form a vehicle to Witch Hazel and other remedies. Label all containers clearly.

Health care items: Adhesive bandages of all sizes, sterile gauze, absorbant cotton wool, adhesive tape, elastic bandage, stitch scissors, forceps (boiled before use), clinical thermometer, assorted safety pins, eye-bath for use as a douche for eye troubles, medicine glass for correct dosage.

Herbal and other items: Comfrey or Chickweed ointment (or cream) for sprains and bruises. Marshmallow and Slippery Elm (drawing) ointment for boils, abscesses, etc. Calendula (Marigold) ointment or lotion for bleeding wounds where the skin is broken. An alternative is Calendula tincture (30 drops) to cupful of boiled water allowed to cool; use externally, as a mouth rinse after dental extractions, and sipped for shock. Arnica tincture: for bathing bruises and swellings where the skin is unbroken (30 drops in a cup of boiled water allowed to cool). Honey for burns and scalds. Lobelia tablets for irritating cough and respiratory distress. Powdered Ginger for adding to hot water for indigestion, vomiting, etc. Tincture Myrrh, 5-10 drops in a glass of water for sore throats, tonsillitis, mouth ulcers and externally, for cleansing infected or dirty wounds. Tincture Capsicum (3-10 drops) in a cup of tea for shock, or in eggcup Olive oil for use as a liniment for pains of rheumatism. Cider vinegar (or bicarbonate of Soda) for insect bites. Oil Citronella, insect repellent. Vitamin E capsules for burns; pierce capsule and wipe contents over burnt area. Friar’s balsam to inhale for congestion of nose and throat. Oil of Cloves for toothache. Olbas oil for general purposes. Castor oil to assist removal of foreign bodies from the eye. Slippery Elm powder as a gruel for looseness of bowels. Potter’s Composition Essence for weakness or collapse. Antispasmodic drops for pain.

Distilled extract of Witch Hazel deserves special mention for bleeding wounds, sunburn, animal bites, stings, or swabbed over the forehead to freshen and revive during an exhausting journey. See: WITCH HAZEL.

Stings of nettles or other plants are usually rendered painless by a dock leaf. Oils of Tea Tree, Jojoba and Evening Primrose are also excellent for first aid to allay infection. For punctured wounds, as a shoemaker piercing his thumb with an awl or injury from brass tacks, or for shooting pains radiating from the seat of injury, tincture or oil of St John’s Wort (Hypericum) is the remedy. ... first aid and medicine chest

Marsupialization

Anaesthesia, Local

Loss of sensation induced in a limited region of the body to prevent pain during examinations, diagnostic or treatment procedures, and surgical operations. Local anaesthesia is produced by the administration of drugs that temporarily interrupt the action of pain-carrying nerve fibres.

Local anaesthetics applied topically before injections or blood tests include sprays and skin creams and ointments.

These are often used for children.

For minor surgical procedures, such as stitching of small wounds, local anaesthesia is usually produced by direct injection into the area to be treated.

To anaesthetize a large area, or when local injection would not penetrate deeply enough into body tissues, a nerve block may be used.

Nerves can also be blocked where they branch off from the spinal cord, as in epidural anaesthesia, which is widely used in childbirth, and spinal anaesthesia, which is used for surgery on the lower limbs and abdomen.

Serious reactions to local anaesthetics are uncommon.

Repeated use of topical preparations may cause allergic rashes.... anaesthesia, local

Hair Transplant

A cosmetic operation in which hairy sections of scalp are removed and transplanted to hairless areas to treat alopecia (baldness). There are several different techniques.

In strip grafting, a strip of skin and hair is taken from a donor site, usually at the back of the scalp or behind the ears. The removed hairs and their follicles are then inserted into numerous incisions made in a bald area, known as the recipient site. The procedure usually takes 60–90 minutes. The patient is given a mild sedative and anaesthetic on the donor and recipient sites. The donor site heals in about 5 days. Transplanted hairs fall out shortly afterwards, but new hairs grow from the follicles 3 weeks to 3 months later.

Other transplant techniques include punch grafting, in which a punch is used to remove small areas of bald scalp, which are replaced with areas of hairy scalp; flap grafting, in which flaps of hairy skin are lifted, rotated, and stitched to replace bald areas; and male pattern baldness reduction, which involves cutting out areas of bald skin and stretching surrounding areas of hair-bearing scalp to replace them.... hair transplant

Nerve Conduction Studies

Tests carried out to assess the extent of nerve damage caused by disorders of the peripheral nervous system (see neuropathy). In the test, an electrical stimulus is applied to a nerve, and the speed at which the nerve responds to the stimulus and transmits a signal is recorded.

nerve injury Damage or severance of conducting fibres within a nerve as a result of trauma, causing loss of skin sensation and muscle power. (See neuropathy for nerve damage from cause.

other than injury.)

If a peripheral nerve (a nerve outside the brain or spinal cord) is only partially severed, the cut fibres may be able to regenerate. Provided the severed ends are still aligned, new fibres can grow across the cut to rejoin the connection, restoring function. If a nerve is totally severed, the individual fibres cannot regenerate successfully and there is no recovery of function. Nerve tracts within the brain and spinal cord are structurally different from the peripheral nerves, and severed fibres in these tracts do not regenerate. For example, vision cannot be restored if the optic nerves are cut.Microsurgery can sometimes be used to stitch a severed peripheral nerve into place, but recovery is rarely complete.... nerve conduction studies

Testis, Torsion Of

Twisting of the spermatic cord that causes severe pain and swelling of the testis. The pain develops rapidly and is sometimes accompanied by abdominal pain and nausea. The testis becomes swollen and very tender, and the skin of the scrotum becomes discoloured. Unless the torsion is treated within a few hours, permanent damage to the testis results. The condition is most common around puberty. It is more likely to occur if the testis is unusually mobile within the scrotum.

Diagnosis is by physical examination.

Surgery is performed to untwist the testis and anchor it in the scrotum with small stitches to prevent recurrence.

If irreversible damage has occurred, orchidectomy is performed.

In either case, the other testis is anchored to the scrotum to prevent torsion on that side.

With prompt treatment, recovery of the testis is complete.... testis, torsion of
