Study On The Relationship Between The Residual Amniotic Fluid And Pregnancy Outcome,the Weight Factors Of Pregnant Women And The Weight Of Newborn With PROM

Objective: To explore the relationship between the residual amniotic fluid and pregnancy outcome,pregnant women’s weight and newborn’s weight with PROM.Methods: 200 pregnant women who underwent prenatal physical examination in our hospital’s obstetric clinic from January 2016 to January 2018 were selected.(1)The pregnant women were divided into three groups according to the amount of amniotic fluid left after PROM:36 cases of oligohydramnios(AFI ≤ 50mm),44 cases of amniotic fluid normal group(AFI ≥ 80mm),120 cases of oligohydramnios(AFI between 50-80mm).(2)According to the BMI index of pregnant women,Divide pregnant women into: 31 cases of low body weight recombination(BMI < 18.5kg /m2)、126 cases of normal weight group(BMI 18.5-24.9kg / m2)、32 cases of super recombination(BMI 25.0-29.9kg / m2)and 11 cases of obesity group(BMI ≥ 30 kg /m2).(3)Pregnant women were divided into three groups according to their weight gain during pregnancy:37 cases of weight gain failure group,80 cases in the standard group and 83 cases of over standard group.Adopt SPSS twenty-three The statistical software processes the data,the counting data is expressed in percentage,the comparison between groups is expressed by chi square test,the measurement data is expressed by mean ± standard deviation,and the comparison between groups is expressed by t test.The relationship between the amount of residual amniotic fluid and the mode of delivery,intrauterine infection,fetal distress and neonatal asphyxia,the relationship between the birth weight of the newborn and the socio demographic characteristics of the pregnant women,the relationship between the birth weight of the newborn and the BMI before pregnancy and the weight gain during pregnancy were analyzed.RESULTS:(1)The rate of cesarean section in oligohydramnios,oligohydramnios and normal amniotic fluid group was as follows 83.33%,44.17%and 25% The rate of cesarean section was the highest in the oligohydramnios group.With the decrease of amniotic fluid,the rate of vaginal delivery was gradually reduced and the rate of cesarean section was increased.(2)The intrauterine infection rates of oligohydramnios group,less amniotic fluid group and normal amniotic fluid group were5.56%,3.33% and 2.27%,respectively.There was no significant difference among the three groups(P>0.05).The difference of fetal distress rate between oligohydramnios group(41.67%)and oligohydramnios group(3.33%)and amniotic normal group(6.81%)was statistically significant(P<0.05),The incidence of fetal distress was higher in oligohydramnios group.The neonatal asphyxia rate of oligohydramnios,oligohydramnios and normal amniotic fluid group were 2.78%,2.50%and 2.27%respectively,There was no significant difference among the three groups(P>0.05).(3)The age,education,occupation and economic income of pregnant women were divided into groups,and the differences of newborn weight were compared,There was no statistical significance(P>0.05).(4)The proportion of hyperrecombined macrosomia(31.25%)was higher than that of low recombined macrosomia(3.22%)and normal weight group(3.17%),The difference was statistically significant(P<0.05),The proportion of super recombination giant is higher;The proportion of normal weight infants in the normal weight group(69.84%)was compared with that in the super recombination group(43.75%),The difference was statistically significant(P<0.05),The pregnant women in the normal weight group were more likely to give birth to normal weight infants,while those in the low weight group,the normal weight group,the super weight group and the obesity group were 38.71%,26.98%,25.00%and 27.27%respectively,There was no significant difference among the three groups(P>0.05).(5)The proportion of low birth weight infants(16.87%)in the overweight group during pregnancy was higher than that in the unqualified group(40.54%),The difference was statistically significant(P<0.05),The probability of delivering low birth weight infants was higher in the non-compliance group.The proportion of low birth weight infants(16.87%)in the overweight group during pregnancy was higher than that in the standard group(35.00%),The difference was statistically significant(P<0.05),The probability of low birth weight infants in the standard group is higher.The proportion of macrosomia in the overweight group during pregnancy(16.87%)was higher than that in the standard group(2.5%)and the non standard group(2.7%),The difference was statistically significant(P<0.05),The probability of giving birth to a huge baby was higher in the over standard group.CONCLUSION:(1)There was a correlation between the amount of amniotic fluid and the outcome of pregnancy.The lower the amount of residual amniotic fluid,the higher the rate of cesarean section.(2)The less the residual amniotic fluid volume in premature rupture of membranes,the higher the incidence rate of intrauterine distress,but no significant correlation with intrauterine infection and neonatal asphyxia.(3)BMI before pregnancy and weight gain during pregnancy are the risk factors that affect the birth of macrosomia.(4)Lack of weight gain during pregnancy is a risk factor for low-weight infants,which has nothing to do with BMI before pregnancy.Pregnant women who fail to achieve weight gain during pregnancy are more likely to give birth to low-weight infants.
