Effect of ritodrine on labor after premature rupture of the membranes.

The effect on labor of administering ritodrine after a premature rupture of the membranes (PROM) was studied in a double-blind trial in 30 patients. The patients were selected according to the following criteria: 28 to 36 weeks' gestation, only 1 fetus, cervix dilated 4 cm or less, and absence of pyrexia or other signs of uterine infection. Fourteen patients received ritodrine and 16 received a placebo. The 2 groups were statistically comparable. None of the patients receiving ritodrine delivered within 24 hours. The difference between the 2 groups was statistically significant with respect to the number of patients delivered within 24 hours (P less than 0.05). However, after 24 hours, there was no difference between the groups as regards the length of pregnancy. The infections registered in the mothers of infants were few and easily controlled. The incidence of idiopathic respiratory distress syndrome (IRDS) was low in the study and allows no conclusions concerning the benefit of prolonging the pregnancy for more than 24 hours after PROM.

Intrapartum electronic fetal monitoring in low-risk pregnancies.

The value of fetal monitoring in low-risk pregnancies was evaluated in 4278 deliveries, 85% of all low-risk patients delivered in 1977 and 1978 at the University Hospital of Lund. An irreproachable tracing was recorded in less than half the cases. Fetal heart rate changes demanding scalp pH measurements or operative intervention for fetal distress occurred in about 10% of all deliveries. In only 30 patients (0.7%) was cesarean section performed for fetal distress. No intrapartal deaths occurred. The perinatal mortality (antenatal deaths excluded) was 0.14%. Only 3 of 1000 newborns had an Apgar score less than 7 at 5 minutes. The reported negative implications of routine fetal monitoring, such as overdiagnosis of fetal distress, cannot be verified in this study when electronic fetal monitoring and pH measurements are combined. The excellent fetal outcome suggests benefits from routine electronic fetal monitoring even in low-risk pregnancies.

Selection criteria for oxytocin stress test.

The main aim of the investigation was to study in which patients oxytocin stress test (OST) should be used. From 1071 patients routinely monitored with antenatal cardiotocography ( = non-stress test) 112 were selected for 151 OSTs for two reasons: 1) normal or suspect pathologic non-stress test (NST) 2) slight or severe pathologic NST regardless of risk classification. In the first group of 85 OSTs, only 2 proved positive. In the second group of 66 OSTs, 22 were positive. The oxytocin stress will give little additional information to the NST when the latter is normal; the OST could be restricted to the relatively few patients with pathologic NST.

Selection criteria for antenatal cardiotocography.

The present report considers two questions: 1) Which patients should be monitored routinely and 2) the interpretation of antenatal cardiotocography. During 26 months 812 patients with risk pregnancies were monitored with antenatal CTG. Most of them were daily registered. One hundred and seventeen (14.5%) showed pathological CTG changes. The CTG patterns were put into four classes according to the degree of seriousness. A comparison between high risk and low risk pregnancies showed that nearly all abnormal CTGs occurred in the high risk group. Within the high risk group, patients with essential hypertension and intrauterine growth retardation had pathological CTG changes in 20--30%. The study shows that high risk pregnancies should be monitored regularly at short intervals to allow early diagnosis of fetal distress. The value of routine CTG in low risk pregnancy can be questioned.

A study of complications in preterm deliveries after prolonged premature rupture of the membranes.

The risk of infection for mother and baby after spontaneous rupture of the membranes was evaluated in a prospective study of 24 patients with ruptured membranes before the 36th week of pregnancy. The mean length of pregnancy after rupture was 10 days and 2 hours. Only patients harboring Group B streptococci or E. coli in the urogenital tract were treated with antibiotics (during delivery). With the exception of 1 woman, all patients harbored one or more pathogens in the urogenital tract. Four mothers were infected but all recovered. One of 26 infants died from infection. The study did not confirm any association between prolonged rupture of the membranes and the frequency of idiopathic respiratory distress syndrome, nor did it contradict attempts to actively prolong pregnancy after rupture of the membranes.
