“…The effect of medical intervention was debatable, but greater awareness of the problems of pregnancy and recourse to induction of labour to prevent postmaturity definitely contributed to lower mortality rates. 2 Similarly, changes in neonatal paediatric practice resulting in improved intensive care for babies of low birth weight changed the outlook for the small baby. 3 The inadequacies of using crude perinatal mortality statistics to study the effectiveness of the perinatal health services have long been recognised, and the desirability of routine provision of standardised perinatal statistics for non-malformed singleton infants has been proposed."…”

“…Essential hypertension: effect of an oral inhibitor of angiotensin-converting enzyme 1979,2,[1106][1107][1108][1109] Summary and conclusions Captopril, a specific oral inhibitor of angiotensinconverting enzyme, was given to 18 unselected patients with moderate essential hypertension. Mean blood pressure fell by 14.5% at the maximum dose given, and this fall was significantly correlated with the initial plasma renin activity.…”

1103reduces the second, and evidently has little effect on the third: thus there is no major penalty to the heart in terms of oxygen uptake for the increased flow that is generated. With the exception of other vasodilators most agents capable of augmenting cardiac output do so at greater metabolic cost.As with most clinical studies, some compromises were made in design to safeguard the overriding interests of the patients. We were anxious to establish the most appropriate treatment for each patient with little delay and were therefore unable to return to control conditions after each infusion rate to distinguish drug effect from possible spontaneous improvement. We thought it justifiable, however, to interrupt treatment once after the 40 ,tg/min dose regimen in eight of our 11 patients to show that the haemodynamic variables returned to the pretreatment values; only mean arterial pressure remained appreciably different from control readings in most patients. We chose to use pulmonary artery end-diastolic pressure as a measure of left ventricular filling pressure to avoid repeatedly wedging the Swan-Ganz catheter, since frequent changes in position or balloon inflation carry small risks. Though the measurement tends to underestimate true left atrial pressure in the presence of heart failure,15 the correlation between the two indices is close and changes are faithfully reflected.Salbutamol has little effect on "backward failure" as shown by the increased pulmonary artery end-diastolic pressure in our patients and therefore cannot be recommended for the treatment of pulmonary oedema in acute myocardial infarction.It is not useful if an increase in blood pressure is believed to be essential. Our results suggest, however, that salbutamol is a useful and safe method of increasing cardiac output in those patients with myocardial infarction in whom poor perfusion is the most important haemodynamic disturbance.

“…In previous retrospective studies, the induction of delivery has been claimed to reduce the perinatal mortality and morbidity, because of an intensified foetal monitoring and reduced frequency of postterm deliveries (12,19,21). Other authors have found an increased frequency of Dip I after induction and consider it to be a risk for developing cerebral injL (27).…”

The effect of induction of labour on the foetus and the newborn was investigated in a prospective randomized study. 41 neonates were studied after induction at full term by amniotomy and intravenous oxytocin infusion. The infusion rate was regulated by the intraamniotic pressure using the Cardiff infusion pump system. 39 neonates served as controls where the labour started spontaneously followed by amniotomy. In both groups foetal heart rate monitoring intraamniotic pressure recordings were performed. There were no differences in Apgar score and pH in cord blood between the groups. The newborns were evaluated the first and the fifth day of life with the Brazelton Neonatal Behavioral Assessment Scale and with a modified Prechtl neurological examination. There were no differences in behaviour and neurological state between the two groups. However, within the groups there were significant differences between the first and the fifth day concerning both neonatal behaviour and neurological state.

“…Fetal monitoring can be used from the beginning of labor. The potential to prevent term fetal death of unknown cause has also been put forward as an argument in favor of elective induction of labor [1,11].…”
