Effect of Three Kinds of Application Methods on Cervical Dilatation for Induced Abortion

Objective:To explore the ideal method on cervical dilatation for induced abortion.Methods:300 cases of early pregnant women were randomly divided into 3 groups.Patients in group A (lidocaine group) exposed the cervix who were injected by 1 mL lidocaine at the 3 and 9 point of the cervix,and abortion operation started after 1 minute.Patients in group B (misoprostol group) were placed 400 μg misoprostol in the rectum 2 hours beforeoperation.Patients in group C (misoprostol combined with lidocaine group)were placed 400 μg misoprostol in the rectum and injected by 1 mL lidocaine at the 3 and 9 point of the cervix 2 hours later,and operation started after 1 minute.Cervical dilatation,analgesia,complications,incidence of abortion syndrome and bleeding were observed in the three groups.Results:The analgesia effect of group C was obviously better than that of group A and group B (P0.01),and the operation time was shorter.The cervical dilation of group C was better than that of group A (P 0.01),but there was no significant difference from group B (P0.05).There was no obvious difference among the blood loss of the three groups (P 0.05).No abortion syndrome happened in groups B and C,while there was 1 case of abortion syndrome in group A.Conclusions:Rectal administration of 400 μg misoprostol combined with lidocaine analgesia for induced abortion can achieve good results of cervical dilatation.Medication is simple,effective,safe and can be widely used.
