Varying Degrees Of Oligohydramnios On The Impact Of Late Pregnancy Outcome

ObjectiveExplore oligohydramnios on the impact of late pregnancy outcome ,and further discuss the varying degrees of oligohydramnios according to amniotic fluid index on the impact of late pregnancy outcome .MethodsSelect 480 cases of puerperas as the observation group, from September 2007 to August 2009 in the Obstetrics of TengZhou Central People's Hospital, the amniotic fluid index≤8cm, according to amniotic fluid index (AFI) all the patients were divided into two groups: Group A's amniotic fluid index≤5cm,Group B's amniotic fluid index>5cm and≤8cm, and 480 examples who randomized sampling amniotic fluid quantity normal puerperas in the same period are the control group.Carries on the clinical observation to object of study's pregnancy outcome, mainly includes the following several targets: fetal heart monitoring, the termination pregnancy time, delivery mode, fetal growth restriction, meconium-stained amniotic fluid, neonatal asphyxia and neonatal death. Patients in the control group compared with observation group and A, B two groups of pregnancy outcome.ResultsAll the patients were taken fetal heart monitoring. It find that NST experiment abnormality patient is 167 cases in observation group and control group is 73 cases.The differences between observation group and control group are statistically significant (P<0.001).The observation group and control group in delivery gestational weeks to compare, obtains P<0.02 through the t-test,the differences between the two groups are statistically significant.The number of cesarean section is 315 cases in observation group, the cesarean section rate is 65.63%.The number of cesarean section is 178 cases in control group, the cesarean section rate is 37.08%.In delivery mode,the differences between observation group and control group are statistically significant (P<0.001).In meconium-stained amniotic fluid,fetal growth restriction,neonatal asphyxia,the differences between observation group and control group are also statistically significant.The observation group was divided into two groups: Group A's amniotic fluid index≤5cm, Group B's amniotic fluid index>5cm and≤8cm, it find that NST experiment abnormality patient is 76 cases in A group and B group is 91,the differences between A group and B group are statistically significant (P<0.001).A group, B group with control group these three groups, in the delivery gestational weeks to compare, uses the variance analysis, P>0.05(F =2.721, P =0.066), the differences are not statistically significant. Between the A and B groups in fetal growth restriction, the differences are not statistically significant. The number of cesarean section is 128 case in A group, the cesarean section rate is 81.01%.The number of cesarean section is 187 cases in B group, the cesarean section rate is 58.07%.In delivery mode,the differences between A group and B group are statistically significant.The rate of neonatal asphyxia is 22.78% in A group,B group is 12.11%.The rate of meconium-stained amniotic fluid is 57.59% in A group,B group is 29.50%,in the rate of neonatal asphyxia and meconium-stained amniotic fluid,the differences between A group and B group are statistically significant.A group,B group compares with the control group, in the fetal growth restriction, cesarean section , meconium-stained amniotic fluid, neonatal asphyxia , on these four indicators are statistically significant differences.There was no neonatal death in each group.ConclusionsIn late trimester of pregnancy,monitoring the quantity of amniotic fluid and screening oligohydramnios are very important for improve neonate prognosis.At present the ultrasonic measurement amniotic fluid quantity is most commonly used by the amniotic fluid exponential method and accurate, the amniotic fluid index (AFI) should be as routine antenatal monitoring indicator. To already full 37 week-long oligohydrammios, when the amniotic fluid index≤5cm pregnancy result is bad, should the prompt cesarean termination pregnancy. When the amniotic fluid index>5cm and≤8cm, you can state in the intensive care intrauterine circumstances, where the vaginal trial production.
