A prospective randomized study was undertaken to evaluate the benefit of intrauterine catheters in induced labour. Two hundred and thirty nine women who had induced labour were studied. The patients in one group had intrauterine catheters inserted and oxytocin was titrated to achieve the 75th percentile of uterine activity observed in spontaneous normal labour according to parity. Contractions were assessed by external tocography in the other group and oxytocin was titrated to achieve 6 to 7 contractions per 15 minutes each lasting > 40 seconds. Mean maximum dose of oxytocin, mode of delivery, Apgar score < 7 at 5 minutes, cord arterial blood pH < 7.15 and admission to neonatal intensive care unit did not differ significantly in the 2 groups. In conclusion, women who had intrauterine catheters did not have a shorter duration of labour, lower dose of oxytocin, fewer operative deliveries or fewer babies in poor condition at birth compared with those who had external tocography in induced labour.
进行了一项前瞻性随机研究，以评估子宫内导管在引产中的益处。对239名引产的妇女进行了研究。一组患者插入子宫内导管，并根据产次将缩宫素滴定至自然正常分娩中观察到的子宫活动第75百分位数。另一组通过外部宫缩图评估宫缩，并将缩宫素滴定至每15分钟6至7次宫缩，每次持续>40秒。两组间缩宫素的平均最大剂量、分娩方式、5分钟时Apgar评分<7、脐动脉血pH<7.15以及入住新生儿重症监护病房的情况无显著差异。总之，与引产时采用外部宫缩图的妇女相比，使用子宫内导管的妇女分娩时间并未缩短，缩宫素剂量未降低，手术分娩次数未减少，出生时状况不佳的婴儿数量也未减少。
