RESUMO
Objective To investigate the clinical effect of restrictive episiotomy in low risk primipara.Methods 100 full-term pregnant women with low risk primipara were divided into observation group and control group according to random number table,50 cases in each group.The patients in the observation group were treated with restrictive episiotomy.The perineum,the second stage of labor,hospitalization time and cost,postpartum sexual life were compared between the two groups.Results In the observation group,the proportion of perineal incision (22.0％ vs.82.0％) was less than that in the control group,the proportion of perineal pain (4.0％ vs.26.0％) was lower than that in the control group,the incidence rate of first degree laceration(38.0％ vs.6.0％) was higher than that in the control group,the differences were statistically significant (x2 =36.058,9.490,14.918,allP ＜ 0.05).The hospitalization time of the observation group was significantly shorter than that of the control group [(3.15 ±0.78)d vs.(3.84 ± 0.98)d],the cost of hospitalization of the observation group was significantly lower than that ofthe control group[(1 814 ± 356) yuan vs.(1 999 ± 387) yuan],the differences were statistically significant (x2 =2.397,3.895,2.488,all P ＜ 0.05).The recovery time of sexual life in the observation group was significantly shorter than that in the control group[(45.6 ± 16.5)d vs.(72.5 ± 23.6)d],and the incidence rate of coital pain was lower than that of the control group (6.0％ vs.24.0％),the differences were statistically significant (x2 =6.606,6.353,all P ＜ 0.05).Conclusion Restrictive episiotomy in low risk primipara has good effect,it is conducive to postpartum recovery.
