目的 探讨自然流产后再次妊娠的间隔时间是否影响围产结局。 方法 对自然流产后 12个月内再次妊娠的 10 2例孕妇进行回顾性调查 ,两次妊娠间隔时间≤ 3个月者为 2 8例 (≤ 3月组 ) ,间隔时间 >3月者 74例 (>3月组 ) ,比较两组围产结局。 结果 两组前置胎盘、早产和胎膜早破的发生率 (3.6 %与 4 .0 % ,3.6 %与 10 .8% ,17.8%与 14 .9% )差异无显著性 (P >0 .0 5 ) ,两组阴道分娩、产钳助产和剖宫产率差异无显著性 (P >0 .0 5 ) ,≤ 3月组低体重儿、巨大儿和 1minApgar评分≤ 7分的发生率分别为 3.6 %、10 .7%和 3.6 % ,与 >3月组 (5 .4 %、9.4 %和 6 .7% )比较 ,差异无显著性 (P >0 .0 5 )。≤ 3月组无一例新生儿转入重症监护室、出生缺陷和死亡 ,而 >3月组有 6例新生儿转入重症监护室 ,2例出生缺陷 ,1例新生儿死亡。 结论 自然流产后再次妊娠的间隔时间可能对围产结局没有影响。
Objective To investigate whether the interval of pregnancy after spontaneous abortion affects perinatal outcome. Methods Retrospective investigation was carried out on 102 pregnant women who relapsed within 12 months after spontaneous abortion. There were 28 pregnant women (≤ March) with two pregnancies less than 3 months and 74 patients with interval> 3 months (> March group), compared two groups of perinatal outcomes. Results There was no significant difference in the incidence of placenta previa, premature labor and premature rupture of membranes between the two groups (3.6% vs 4.0%, 3.6% vs10.8%, 17.8% vs14.9%) (P> 0.05). There was no significant difference in the rate of cesarean section and cesarean section between the two groups (P> 0.05), the incidence of ≤3 months in ≤3 months group, giant child and 1 min of apgar score Were 3.6%, 10.7% and 3.6%, respectively. There was no significant difference between the three groups (5.4%, 9.4% and 6.7%) (P> 0.05). No newborn infants were admitted to intensive care unit, birth defects and deaths in ≤ 3 months group, while 6 infants in> March group were transferred to intensive care unit, 2 were born with defects and 1 died of newborns. Conclusion The interval of pregnancy after spontaneous abortion may have no effect on perinatal outcome.
