Clinical observation on the time of termination of pregnancy and method of delivery in pregnant patients with hypertension

Objective To discuss the clinical influence of time of termination of pregnancy and method of delivery for pregnancy outcomes in pregnant patients with hypertension.Methods 156 pregnant patients with hypertension were divided into less than 34 weeks group with 22 pa-tients,34-36 weeks group with 41 patients,over 36 weeks group with 93 patients according to the time of the termination of pregnancy,and two groups including vaginal delivery group with 38 patients and cesarean section group with 118 patients according to delivery methods.The birth weight,neonatal asphyxia,neonatal mortality,maternal morbidity were contrasted between the three and two groups.Results The birth weight in the less than 34 weeks group were signifi-cantly lower than that the 34-36 weeks group and above 36 weeks group (P <0.01).The 34-36 weeks group was significantly lower than that in the above 36 weeks group(P <0.01).Neona-tal asphyxia and neonatal mortality in the less than 34 weeks group were significantly higher than that in the 34-36 weeks group and above 36 weeks group(P <0.01 or P <0.05).The 34-36 weeks group was significantly higher than that in the above 36 weeks group(P <0.05).But the difference was not significant in maternal morbidity in the three groups (P > 0 .0 5 ).The birth weight in the vaginal delivery group were significantly lower than that in the cesarean section group(P <0.01).And the neonatal asphyxia,neonatal mortality,and maternal morbidity in the vaginal delivery group were significantly higher than that in the cesarean section group (P <0.01).Conclusion Pregnancy patients with hypertension in shorter gestational time should be given reasonable treatment to extend pregnancy time.And they should terminate pregnancy at about 36 weeks of pregnancy and operate cesarean section to reduce the damage to the fetal.In this way,neonatal and maternal perinatal morbidity can reduce.
