It is carried out using such drugs as *prostaglandins to prime the cervix and/or *amniotomy prior to synthetic *oxytocin (Syntocinon), which stimulate uterine contractions. Induction of labour is carried out if the wellbeing or life of mother or child is threatened by continuance of the pregnancy. 2. (in anaesthesia) initiation of *anaesthesia. General anaesthesia is usually induced by the intravenous injection of short-acting *anaesthetics, e.g. thiopental.

Induction Of Labour

Use of artificial means to initiate childbirth when the health of the mother or baby would be at risk if pregnancy continued. The most common reason for inducing labour is that the pregnancy has continued past the estimated delivery date, which increases the chance of complications during childbirth. Other reasons for inductionare pre-eclampsia, Rhesus incompatibility, or intrauterine growth retardation. Different methods of induction are used, depending on the stage of labour: a prostaglandin pessary may be inserted into the vagina to encourage the cervix to open; if the cervix is already open, the membranes containing the fetus may be ruptured; or the hormone oxytocin may be given intravenously to stimulate uterine contractions. industrial diseases See occupational disease and injury.

Induction Loop System

(loop system) a device for helping people with some types of *hearing aid or *cochlear implant to hear more effectively in certain situations. Electrical signals from a television, sound system, or microphone are passed through an amplifier to a wire that is positioned in a loop encompassing the desired listening area. This creates an electromagnetic field that can be picked up by a coil within the hearing aid or cochlear implant. Induction loops are installed in such places as public buildings, lecture theatres, classrooms, and churches. See also assistive listening device.... induction loop system
