Lack of beta-endorphin plasma level rise in oxytocin-induced labor.

beta-Endorphin (beta-EP), beta-lipotropin (beta-LPH) and cortisol plasma levels were measured during labor in 18 pregnant women. In 7 cases labor progressed spontaneously and in 11 cases oxytocin (5 mIU/min) was administered to stimulate uterine contractions. In control and oxytocin-treated subjects hourly blood samples were taken until delivery. In spontaneous labor all three hormones showed a progressive and significant increase until parturition. In oxytocin-treated patients, however, both beta-EP and beta-LPH remained constant until parturition. Cortisol levels in oxytocin-treated patients presented a significant increase but reached values significantly lower than in control patients. These results indicate that women with uterine hypocontractility during labor requiring oxytocin showed no rise in their plasma beta-EP and beta-LPH and a blunted cortisol rise during oxytocin administration.

Comparison of induced versus non-induced labor in post-term pregnancy. A randomized prospective study.

OBJECTIVE: To determine the proper management of pregnancy in uncomplicated cases going beyond 42 weeks. DESIGN: Randomized controlled trial of induction of labor at or shortly after the 42-week limit, versus close monitoring without induction except when indicated for medical reasons. SETTING: Hospital's obstetrical department STUDY POPULATION: 188 pregnant women, randomly allocated to two groups with 94 in each. INTERVENTIONS: Induction of labor by stripping of membranes and i.v. oxytocin infusion, with artificial rupture of membranes when the cervical opening was 3 cm or more in diameter. The control group was followed with clinical, biochemical and electronic tests, intervention being applied according to needs. END POINTS: Frequency and modes of operative delivery, maternal and perinatal morbidity and mortality. MAIN RESULTS: The distribution of gestational age (in weeks) at birth was almost identical in the two groups, but there were more operative deliveries in the control group than in the induction group (64 versus 48, p less than 0.05). Maternal complications and perinatal morbidity rates were equally distributed between the groups. There was one perinatal death in the induction group and two deaths among the controls. CONCLUSION: With due reservation for small numbers, routine induction after term may result in fewer operative deliveries. No other advantage has been demonstrated when compared with close monitoring and intervention when medically indicated.
