Résumé
Objective To discuss the safety and operation effect of cesarean sectionof patients with early onset severe preeclampsia.Methods Clinical data were retrospectively analyzed,the treatment group made up of 236 patients with severe preeclampsia whose gestational age from 28 to 33 +6 weeks and the control group with 399 pregnancy women above 34 weeks.Main analytical items included:onset of gestational age,gestational age of termination of pregnancy,protensive of gestation,methods of termination of pregnancy,status of the occurrence of serious complications,fetal and neonatal mortality and the rate of neonatal asphyxia.Results The average conservative treatment time of treatment group was was significantly longer than that of control group [ ( 13.5 ± 1.2) d vs (9.6 ± 1.0 ) d,t =3.760,P ＜ 0.001].There was no significant difference on the cesarean section rate[70.8％ (167/236) vs 71.2％ (284/399),x2 =0.012,P =0.911 ] and neonatal mortality(2.5％vs 2.8 ％,x2 =0.026,P =0.871 ) between these two gourps.However there was significant difference on the rate of neonatal asphyxia(25.8％ vs 10.8％,x2 =20.792,P ＜ 0.001 ) and perinatal mortalit (22.0％ vs 6.9％,x2=27.782,P ＜ 0.001 ) between these two groups.Conclusion For the patients with severe early onset preeclampsia,to take conservative expectant treatment appropriately based on the safety of motherhood could avoid or reduce the possibility of the occurrence of serious complications,could extend the gestational age appropriately as well as reduce fetal and neonatal prevalence and mortality.Cesarean section is proper for the termination of pregnancy.
