The influence of spasmoanalgetic Dolantin on electrical activity of the smooth musculature of the cervix during labour was studied in 50 primiparous women after induction of labour. The highest electrical activity was measured at the time of uterine contraction (AC) and between contractions (BC). The basic pattern of Dolantin-produced changes in muscular contractions in the cervix observed via EMG activity is that of the EMG activity diminishing with contractions of the uterine corpus and even more so in the period between contractions. Dolantin administered during the latent phase of induced labour did not accelerate cervical dilatation either in the latent or in the active phase of amniotomy- and Oxytocin-induced labour.

We investigated whether opiate analgesics as commonly administered to women during labor would affect later response to maternal separation in infant guinea pigs. Meperidine hydrochloride (10-15 mg/kg i.m.) was administered to late-pregnant guinea pigs 5 min prior to labor induction with oxytocin. On Day 11 or 12 postnatal, pup distress vocalizations, locomotor activity, and plasma cortisol were measured under one of two conditions: alone (alone in a novel environment for 30 min) or mother (with the dam in the novel environment). Female pups exposed to intrapartum meperidine emitted fewer vocalizations than controls in the alone condition. Plasma cortisol was higher in meperidine females in the alone condition than in controls at the end of the separation period, but the difference was not significant. There was no drug effect on vocalizations or cortisol in males. Neither test condition nor drug affected activity level. The data suggest that intrapartum opiates may alter separation-induced distress in female guinea pig infants.
