The aim of the study was to investigate pudendal nerve function after a non-instrumented vaginal delivery. Seventeen primiparae women who had had a non-instrumented vaginal delivery were examined 3-5 days and 3 months after delivery. At both assessments pudendal nerve terminal motor latency (PNTML) was measured. The PNTML was found to decrease significantly from 2.64 ms in the first few days after delivery to 1.95 ms 3 months after delivery (P = 0.00009). PNTML decreased in all but one of the 17 women during the observation period. Immediately after delivery 9 women (53%) had a pathological high PNTML value, which was normalized 3 months later in all but 1. It was concluded that pudendal nerve function is often impaired immediately after a non-instrumented vaginal delivery, but recovers in most women over a 3-month period.
该研究的目的是调查非器械助产阴道分娩后阴部神经的功能。对17例非器械助产阴道分娩的初产妇在产后3 - 5天和3个月进行检查。在两次评估中均测量了阴部神经终末运动潜伏期（PNTML）。发现PNTML从产后头几天的2.64毫秒显著降至产后3个月的1.95毫秒（P = 0.00009）。在观察期内，17名女性中除1人外，其余所有人的PNTML均下降。分娩后立即有9名女性（53%）的PNTML值病理性升高，3个月后除1人外其余均恢复正常。得出的结论是，非器械助产阴道分娩后，阴部神经功能常在分娩后立即受损，但在大多数女性中会在3个月内恢复。
