背景/目的：分娩持续时间因妊娠而异，少于12小时被认为是正常的。现代产科实践包括积极的分娩管理，目的是防止分娩时间延长及其后遗症。本研究的主要目的是确定和比较的平均持续时间之间的自然发病的劳动力nulluliasis（Po）和multiplyasis（P.1），并确定影响因素的劳动力duration of labor.Materials and Methods：本研究是一项前瞻性研究进行了2004年5月15日和6月14日在劳动病房的大学伊洛林教学医院，伊洛林，尼日利亚。238名符合纳入标准的妇女进行了研究。结果：多胎妊娠分娩室平均入院-分娩时间（3.77 ± 2.88）h明显短于初产妇（5.00 ± 3.17）h（P = 0.235）;产程（从临产开始到分娩）的平均+/- SD持续时间在多次妊娠组（8.73 +/- 4.17小时）比未妊娠组（11.23 +/- 4.29小时）短（P = 0.426）。差异无显著性（t检验，P > 0.05）。产妇年龄、产次与产程时间有显著相关性（Pearson相关系数分别为-0.019、-0.027，P < 0.05）。产程时间与母亲年龄、个体产次相关。
Background/Objective: Duration of labor varies from one pregnancy to another and a period of less than 12 hours is regarded as normal. Modern obstetric practice involves active management of labor with the aim of preventing prolonged labor and its sequelae. The main objective of this study was to determine and compare the average duration of labor of spontaneous onset between nulliparas (Po) and multiparas (P.1) and to determine factors affecting duration of labor.Materials and Methods: This study was a prospective study carried out between 15 May and 14 June 2004 at the Labor Ward of the University of Ilorin Teaching Hospital, Ilorin, Nigeria. Two hundred and thirty-eight women who satisfied the inclusion criteria were studied. The inclusion criteria were term pregnancy with vertex presentation, labor with spontaneous onset, live fetus at presentation and spontaneous vertex delivery.Results: The mean +/- SD admission-delivery interval in labor ward was shorter (3.77 +/- 2.88 hours) among multiparas than that of nulliparas (5.00 +/- 3.17 hours) (P = 0.235). The mean +/- SD duration of labor (from the onset of labor to delivery) was shorter among multiparas (8.73 +/- 4.17 hours) than that of nulliparas (11.23 +/- 4.29 hours) (P = 0.426). The differences were not significant (t-test, P > 0.05). Maternal age and individual parity had significant correlation with the duration of labor in this study (Pearson correlation = -0.019, -0.027, respectively, P < 0.05).Conclusion: Interestingly, duration of labor was not significantly different among multiparas and nulliparas although it was shorter. Correlation existed between duration of labor and maternal age and individual parity.
