胎膜早破对宫内羊水量的影响

足月胎膜早破中胎儿窘迫及难产发生率都有增加,其发生原因可能与羊水流失有关,本文对1988年1—5月在我院住院的32例胎膜早破进行了羊水量变化及临床经过的观察并与对照组相比较,结果表明,胎膜早破后,宫腔内羊水量都有减少,其程度随时间延长而加重,当破膜时间超过24小时,最大羊水池直径都在3cm以下,胎儿窘迫发生率及手术产率都较对照组为高,本文结果说明既往常规等待24小时的做法,对母胎不利,应及早引产为宜。

Effect of premature rupture of membranes on the amniotic fluid volme

Premature rupture of membranes (PROM) is of concern because of its many complications which are dangerous for both mother and fetus. One of those complications is the loss of amniotic fluid that may, cause feual distress and difficult lacbor. From January to May, 1988, there were 32 cases of term PROM with singleton in cephalic presentation in our hospital; the effect of PROM on the volume of amniotic fluid and the clinical course were studied. The result showed that the volume was decreased in all cases. The vertical diameter of the largest pocket of amniotic pool was less than 3cm if the latent time was beyond 24 hours. The incidence of fetal distress and surgical delivery were higher in PROM as compared with control group. According to our data, an earlier induction of labor instead of waiting for 24 hours is recommended.
