羊水过少可发生在妊娠各期,但以晚期妊娠为常见。妊娠晚期羊水量少于300 ml者,称羊水过少。羊水过少的发生率为0.4%~4%,当羊水量少于50 ml时,围生儿病死率高达88%,是正常妊娠围生儿的13~47倍,并使剖宫产率增加[1]。现对羊水过少的143例患者资料进行分析,探讨羊水过少对母儿的影响和早期合理的临床处理措施。1资料与方法1.1一般资料收集我院2011年9月至2013年 Oligohydramnios can occur in all stages of pregnancy, but late pregnancy is common. Late pregnancy, amniotic fluid less than 300 ml, said oligohydramnios. The incidence of oligohydramnios is 0.4% to 4%. When the amniotic fluid volume is less than 50 ml, the perinatal mortality rate is as high as 88%, which is 13 to 47 times that of normal infants and increases the rate of cesarean section [1]. 143 cases of patients with oligohydramnios are now analyzed data to explore the impact of oligohydramnios on the mother and child and early rational clinical treatment. 1 Materials and Methods 1.1 General Information Collection September 2011 to 2013 in our hospital
