The main purpose of physiologic delivery is to rely on mother's body for childbirth. In physiologic delivery method pregnant women attend delivery preparation classes and they learn how to overcome fear and pain. This study compares delivery outcomes among women who participated in physiologic delivery with those who had undergone non-physiologic delivery.
All patients referred for physiologic delivery were assessed. Exclusion criteria were lack of PROM, post date, cephalopelvic disproportion, multi-fetal pregnancy, Meconium stain, blood pressure above 90/140, placenta previa and previous record of cesarean. Data was entered in SPSS 16 software and Fisher and Chi-square tests were used to compare vaginal laceration, episiotomy and Apgar score between two groups.
Twelve out of 73 pregnant women (16.4%) in physiologic delivery group and 27 out of 69 pregnant women (39.1%) in non-physiologic delivery group needed episiotomy (P = 0.002). Ten patients (13.7%) in physiologic delivery group and seven persons (10.1%) in the non-physiologic delivery group were suffering from vaginal laceration (P = 0.51). There was no significant statistical difference between newborns' Apgar score in two groups.
Physiologic delivery can reduce the need for episiotomy without any further complications.
生理性分娩的主要目的是依靠母亲的身体进行分娩。在生理性分娩方法中，孕妇参加分娩准备课程，学习如何克服恐惧和疼痛。本研究比较了参与生理性分娩的妇女与接受非生理性分娩的妇女的分娩结局。
对所有转诊进行生理性分娩的患者进行评估。排除标准为胎膜早破、过期妊娠、头盆不称、多胎妊娠、胎粪污染、血压高于90/140、前置胎盘和既往剖宫产史。数据录入SPSS 16软件，采用Fisher检验和卡方检验比较两组之间的阴道裂伤、会阴切开术和阿氏评分。
生理性分娩组73名孕妇中有12名（16.4%）需要会阴切开术，非生理性分娩组69名孕妇中有27名（39.1%）需要会阴切开术（P = 0.002）。生理性分娩组10名患者（13.7%）和非生理性分娩组7名患者（10.1%）发生阴道裂伤（P = 0.51）。两组新生儿阿氏评分无显著统计学差异。
生理性分娩可减少会阴切开术的需求，且无任何进一步并发症。
