Neonatal Mortality: From 1 Different Sources
Neonatal mortality is the mortality of infants under one month of age. In England and Wales this has fallen markedly in recent decades: from more than 28 per 1,000 live births in 1939 to 3.6 in 2002. This improvement can be attributed to various factors: better antenatal supervision of expectant mothers; care to ensure that expectant mothers receive adequate nourishing food; improvements in the management of the complications of pregnancy and of labour; and more skilled resuscitation at birth for those who need it.
Nearly three-quarters of neonatal deaths occur during the ?rst week of life. For this reason, increasing emphasis is being laid on this initial period of life. In Britain, in the last four decades of the 20th century, the number of deaths in the ?rst week of life fell dramatically from 13.2 to just over 2.7 per 1,000 live births. The chief causes of deaths in this period are extreme prematurity (less than 28 weeks’ gestation), birth asphyxia with oxygen lack to the brain, and congenital abnormalities. After the ?rst week the commonest cause is infection.

The provision of a dedicated unit with special facilities, including one-to-one nursing and appropriate technology, for caring for premature and seriously ill newborn babies. Paediatricians and neonatologists are involved in the running of such units. Not every maternity unit can provide intensive care: for example, the provision of arti?cial ventilation, other than as a holding procedure until a baby can be transferred to a better-equipped and better-serviced unit. Such hospitals tend to have special-care baby units, which are capable of looking after the needs of most, but not all, premature or ill babies.... neonatal intensive care

A very common, harmless skin condition, also known as erythema neonatorum or toxic erythema, that affects newborn infants. A blotchy rash, in which raised white or yellow lumps are surrounded by illdefined red areas of inflammation, forms, mainly affecting the face, chest, arms, and thighs. The cause of neonatal urticaria is unknown. The rash usually clears up without treatment.... urticaria, neonatal

an assessment tool for newborn babies, consisting of a chart in which a combination of *vital signs, neurological involvement, observation of blue skin and lips, and level of behavioural response indicate the appropriate level of concern. It is colour-coordinated from red to green to enable standardized escalation of concerns about the sick baby.... neonatal early warning score
(IMR) the number of deaths of children under one year of age per 1000 live births in a given year. Included in the IMR are the neonatal mortality rate (calculated from deaths occurring in the first four weeks of life) and postneonatal mortality rate (from deaths occurring from four weeks). Neonatal deaths are further subdivided into early (first week) and late (second, third, and fourth weeks). In prosperous countries neonatal deaths account for about two-thirds of infant mortalities, the majority being in the first week (in the UK the major cause is prematurity and related problems). The IMR is usually regarded more as a measure of social affluence than a measure of the quality of antenatal and/or obstetric care; the latter is more truly reflected in the *perinatal mortality rate.... infant mortality rate
the number of deaths due to complications of pregnancy, childbirth, and the puerperium per 100,000 live births (see also stillbirth). In 1952 concern about maternal mortality resulted in Britain in the setting up of a triennial *confidential enquiry into every such death to identify any shortfall in resources or care. The first triennial report was published in 1985. Since 2014 reports have been produced annually by MBRRACE-UK (Mothers and Babies: Reducing Risk through Audits and Confidential Enquiries Across the UK). Levels of *maternal deaths are currently low: a report published in 2017 (covering 2013–15) counted 202 obstetric-related deaths (8.76 per 100,000 live births). Thromboembolism was the commonest direct cause of death (30 deaths, 1.13 per 100,000 live births), while heart disease was the commonest indirect cause of death (54 deaths, 2.34 per 100,000 live births).... maternal mortality rate
(NAS) symptoms and signs exhibited by a newborn baby (neonate) due to drug withdrawal (see dependence). This results when the fetus has been exposed to addictive drugs through maternal substance abuse or misuse. Symptoms tend to occur in the first few days of life (in the case of methadone, which is a long-acting opioid, symptom onset may be delayed). They include tremors and jerking, high-pitched crying, sneezing, sucking of fists, feeding difficulties, shortened periods of sleep between feeds, rapid breathing, sweating, loose stools, nasal stuffiness, and frequent yawning. Treatment includes swaddling or snugly wrapping in a blanket, as babies with NAS are often difficult to comfort. Other nonpharmacological measures include frequent small feeds using high-calorie formula and intravenous fluids if babies become dehydrated. Drug therapy may be used for seizures and withdrawal symptoms.... neonatal abstinence syndrome

(PNM) the total number of babies born dead after 24 weeks gestation (*stillbirths) and of live-born babies that die in the first week of life, regardless of gestational age at birth (early neonatal deaths), per 1000 live births and stillbirths.
