目的探讨短产的特点及后果。方法将99例单胎头先露且产程持续3小时或更短的足月妊娠与产程更长的对照组进行比较，并根据产妇年龄、产次和出生体重与指标病例相匹配。结果短产多发生于多胎妊娠。在这些病例中，第一和第二产程都被发现缩短。在短产程病例中，胎盘脱垂、子宫收缩过快和母体使用可卡因的情况明显更多。严重会阴撕裂伤、产后出血、产伤和低Apgar评分在病例组和对照组之间分布大致相等。短产程中不良结局的优势发生在扩张率和下降率超过规定的第95百分位数限值的亚组中。结论分娩时间小于或等于3小时与胎盘早剥密切相关，但不是母儿发病的主要因素。
Objective To determine the characteristics and consequences of short labor. Methods Ninety-nine term pregnancies with singleton vertex presentation and labor lasting 3 hours or less were compared with controls with longer labor, matched to the index cases by maternal age, parity, and birth weight. Results Short labor occurred mostly in multiparas. Both the first and second stages of labor were found to be shortened in these cases. There was significantly more placental abruption, uterine tachysystole, and maternal cocaine use among short-labor cases. Major perineal lacerations, postpartum hemorrhage, birth trauma, and low Apgar scores were distributed approximately equally between cases and controls. A preponderance of the bad outcomes in the short labors occurred in the subgroup of those with rates of dilatation and descent that exceeded established 95th percentile limits. Conclusions Labors of 3 hours or less in duration were strongly associated with placental abruption, but were otherwise not major contributors to maternal and fetal morbidity.
