ABSTRACT
Objective To explore clinical effect of dinoprostone in premature rupture of the membranes at term cervical ripening.Methods 42 cases with premature rupture of the membranes at term cervical ripening were selected.All patients were randomly divided into two groups.The dinoprostone group had 21 cases,which applied the treatment of dinoprostone belt the posterior fornix of vagina medicine induced abortion.The oxytocin group had 21 cases,which applied the treatment of intravenous drip oxytocin.The time of induction labor,6h,12h cervical Bishop score after using the medication,drugs acting time,labor conditions and perinatal situation,pregnancy outcome and some other index were observed.Results It taken (6.18 ± 4.48 ) h until parturient and ( 12.62 ± 8.03 ) h until the cervical mouth full open in the dinoprostone group,which were shorter than the oxytocin group,that taken( 10.21 ±5.42) h,( 18.87 ± 9.14) h.( t =2.62,2.35,all P ＜ 0.05 ).There was no significant difference about cervical Bishop score before using the medication.It's(7.52 ± 2.44 ) point 6h after using the medication and( 9.03 ± 1.96 ) point 12h after in the dinoprostone group.They were better than the oxytocin group,which were(5.97 ± 1.95 )point,(7.13 ±2.12 )point.It was significantly different( t =2.27,3.02,all P ＜0.05 ).The average incubation period of dinoprostone group wss (9.91 ± 1.73 )h.It's longger than the oxytocin group,which was( 8.72 ± 1.34)h.The active period of dinoprostone group was(4.36 ± 0.66 ) h.It's shortter than the oxytocin group,which was( 5.84 ± 1.02 ) h.The difference was significant( t =2.49,5.58,all P ＜ 0.05 ).There was no significant difference in the second and third stage of laber between the two groups( t =0.56,0.33,all P ＞ 0.05 ).There was also no significant difference about intrauterine distress,amniotic fluid contamination,cesarean section,intestinal bleeding,the Apgar score of newborns and some other index in the two groups ( x2 =0.00,0.00,0.52,t =0.84,1.04,all P ＞ 0.05 ).Conclusion Dinoprostone had good promoting effect on cervical ripening for preterm premature rupture of membranes pregnant woman.Its effect was better than oxytocin and it was safe to use.
