A prospective study in 180 mothers and babies examined the effects of oxytocin in induced labour on plasma bilirubin levels in cord blood, as well as on the incidence of neonatal jaundice. Raised plasma bilirubin levels in cord blood, probably enhanced by breakdown of fetal red cells, appeared to be a dose dependent effect of oxytocin. Commensurate with this was the finding that a larger proportion of babies in the induced group manifested a greater severity of jaundice.

A retrospective study of 12 461 single births confirmed an association between maternal oxytocin infusion and neonatal jaundice. The effect of oxytocin on jaundice was independent of gestational age at birth, sex, race, epidural anaesthesia, method of delivery, and birth weight, each of which was significantly associated with neonatal jaundice. The effect of oxytocin was, however, small, producing a calculated mean increase in peak plasma bilirubin concentration of 8.6 mumol/1 (0.5 mg/100 ml); this excess was independent of sex and less than the effect of the baby being born one week earlier.

An investigation was made into the onset and severity of neonatal jaundice in 114 patients following spontaneous labour and labour induced by (a) amniotomy, (b) amniotomy and simultaenous infusion of oxytocin, (c) amniotomy and simultaneous administration of oral prostaglandin E2 (PGE2). No significant difference in serum bilirubin levels in the first five days of life was found in the four groups.

Concern about a neonatal jaundice rate of 8-6 per cent prompted a retrospective survey of 981 full term infants. There was a highly significant association between increased oxytocin dosage and neonatal jaundice in induced labours. A significant association was also demonstrated between neonatal jaundice and both breast-feeding and minor infections. No association was demonstrated between neonatal jaundice and the method of delivery of birth weight. The results of the survey suggest that while oxytocin in high doses should be used with caution, the benefits obtained from the drug outweigh the risk of hyperbilirubinaemia which it may cause.

A retrospective controlled study using data from the Cardiff Births Survey examined a possible relation between oxytocin administration to induce or accelerate labour and the subsequent development of neonatal jaundice. Among 10 591 infants born in Cardiff between 1970 and 1972 the incidence of neonatal jaundice was higher in infants born after oxytocin administration than among others. Analysis by gestational age at delivery, birth weight, Apgar score, length of labour, sedative and analgesic therapy during labour, and suppression of lactation showed that this association held within all these categories except among small immature infants, who are at high risk of jaundice in any case.

The Authors have correlated neonatal jaundice with the administration of oxytocin and prifinium bromide to the mother either alone or in association during labour. The percentage of neonatal jaundice in women treated with ritodrine hydrochloride during the second and third trimester of pregnancy was also calculated. A total of 1.101 deliveries were taken into consideration between January 1984 and June 1986. Thirty-three patients were treated with oxytocin alone; 444 patients with oxytocin and prifinium bromide; 81 patients with ritodrine hydrochloride during the second and third trimesters of pregnancy, and 192 patients were untreated. This study indicates that all drugs may contribute to producing neonatal jaundice, as shown in the graphs, and drugs during labour should be used with extreme caution and be limited in quantity and period.

To determine the effects of fluid restriction in induced labour with oxytocin in 5% dextrose solution, maternal venous blood and fetal cord venous blood were examined in 164 mothers in induced labour and 29 mothers with a spontaneous onset of labour. After satisfactory uterine activity was induced either the oxytocin infusion was managed according to routine delivery unit practice (n = 36), or infusion rates were halved (n = 45), or quartered (n = 43), or discontinued (n = 40). Despite fluid restriction during labour the mean sodium concentration in maternal blood or cord blood had fallen to a similar extent in all four induced groups at delivery. Potassium, urea, creatinine, total protein, and albumin in maternal blood or cord blood were affected differently by induced labour as compared with sodium. The fall in sodium concentration in maternal blood was a more consistent reflection of the total volume of fluid received, mean infusion rates and cord blood sodium after infusion rates were quartered or discontinued. The incidence of hyponatraemia was 5% in mothers and 8% in infants. A comparison of hyponatraemic and normonatraemic cord blood showed no significant differences in serum bilirubin levels or red cell counts, but more hyponatraemic infants developed neonatal jaundice. It is suggested that in induced labour fluid restriction alone does not prevent hyponatraemia and neonatal jaundice.

A prospective randomized controlled trial of 202 patients was set up to examine the efficiency and safety of 40 mg of intravaginal prostaglandin F2 alpha (PGF2 alpha) in a tylose gel to stimulate labour after artificial or spontaneous membrane rupture. The control group received a standard intravenous oxytocin regimen. The PGF2 alpha treated group had a significantly shorter length of labour (6.2 +/- 3.6 hours) compared to the oxytocin group (7.5 +/- 4.3 hours) (p less than 0.05). The analgesic requirements were significantly reduced in the PGF2 alpha treated patients. In PGF2 alpha treated patients 46 of 105 required no analgesia whereas 17 of 97 oxytocin treated patients required no analgesia (p less than 0.001). There were similar reductions for epidural (p less than 0.005) and pethidine requirements (p less than 0.005). No differences were found between groups with regards mode of delivery. There were no adverse maternal side-effects associated with PGF2 alpha usage. A significant reduction (p less than 0.05) in the incidence of neonatal jaundice requiring phototherapy occurred in the PGF2 alpha group. Prostaglandin F2 alpha appears to be a safe, efficient and better alternative to intravenous oxytocin to stimulate labour in the presence of ruptured membranes, allowing ambulation, a reduction in length of labour and less need for analgesia and intravenous therapy.

A total of 821 patients, 39-40 weeks pregnant, was obstetrically normal at admission. In 212 of them intra-uterine pressure (IUP) was monitored before and during inducing labor by oxytocin, in 212 patients delivery was also induced by oxytocin but not monitored, in 197 by combining oxytocin and amniotomy, and 200 had spontaneous delivery. Inducibility could be predicted by uterine baseline activity and a 50 mu i.v. shot of oxytocin, together with determination of cervical status and placental location. The duration of labour induction was affected by parity, placental location and cervical status, but was predicted only to a minor degree by baseline activity and uterine oxytocin sensitivity. Amniotomy did not affect caesarean, section rate. The newborn child benefited from IUP monitoring: fewer transfers to pediatrics were necessary, there was less neonatal jaundice and fewer blood exchanges. It is assumed that if labor is not monitored through IUP, oxytocin may cause neonatal hyperbilirubinaemia through episodes of increased uterine resting pressure.

A prospective study of 78 neonates provides evidence for an association between maternal oxytocin infusion and neonatal jaundice. On the second and fifth days infants of mothers whose labour had been induced by amniotomy followed immediately by intravenous oxytocin (group C) had mean total bilirubin levels significantly higher (P <0.05) than did infants whose mothers had had a spontaneous onset of labour and did not require oxytocin (group A). Bilirubin levels in infants of mothers whose onset of labour was spontaneous but required oxytocin to accelerate progress (group B) did not differ significantly from group A.Though these findings suggest a dose dependent effect of oxytocin, other possible explanations are suggested which take into account other drugs administered to the mother and also differences in the corticosteroid status of the groups of infants.
