早产可由胎膜早破、多胎妊娠、宫颈机能不全、胎儿畸形、子宫肌瘤、子宫畸形、重度子痫前期、胎盘早剥或各种其他内科和产科并发症引起。研究表明，早产往往是由上生殖道感染。因此，早产的病因往往不同于足月分娩。术语“自发性早产”经常被应用时，没有诱发因素已被确定。也许“特发性早产”是更准确的描述。通过超声波对胎儿体重的估计，可以明显看出先前异常对早产胎儿的影响。对于一个给定的胎龄，那些随后早产的估计体重显着低于那些最终在足月分娩。因此，早产是一个产科问题，并不是孤立发生的。最佳管理需要意识到
Preterm delivery can result from premature rupture of the membranes, multiple gestation, incompetent cervix, fetal malforma-tion, fibroid uterus, uterine malformation, severe preeclampsia, abruptio placentae, or a wide variety of other medical and obstetric complications. Studies suggest that preterm labor is often preceded by upper genital tract infection. Thus, the etiology of preterm labor often differs from that of labor at term. The term “spontaneous preterm labor” has often been applied when no predisposing factor has been identified. Perhaps “idiopathic preterm labor” would be a more accurate description. The influence of preceding abnormalities on the fetus who delivers prematurely is apparent from ultrasound estimates of fetal weight. For a given gestational age, the estimated weights of those with subsequent preterm delivery are significantly lower than those who ultimately deliver at term. Thus, preterm delivery is an obstetric problem that does not occur in isolation. Optimal management requires an awareness of the
