Continuous versus interrupted sutures for perineal repair.

backgroundMillions of women worldwide undergo perineal repair after childbirth and the type of repair may have an impact on pain and healing.

objectivesThe objective of this review was to assess the effects of continuous subcuticular versus interrupted transcutaneous sutures on women following perineal repair. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register. Date of last search: June 1999. SELECTION CRITERIA: Randomised trials comparing continuous subcuticular versus interrupted transcutaneous sutures for the closure of perineal skin after vaginal delivery. DATA COLLECTION AND ANALYSIS: Trial quality was assessed independently by two reviewers. Data were extracted by one reviewer and checked by the second reviewer. Study authors were contacted for additional information. MAIN

resultsFour studies involving 1864 women were included. The trials were heterogeneous with respect to operator skill and training. Compared with interrupted sutures, a continuous subcuticular suture technique of perineal repair was associated with less pain for up to 10 days post partum (odds ratio 0.68, 95% confidence interval 0.53 to 0.86). No differences were seen in the need for analgesia, need for resuturing of the wound or in dyspareunia. Based on one trial only, there was no difference in long-term pain and failure to resume pain-free intercourse within three months of the birth. The continuous technique was associated with less need for the removal of sutures. REVIEWER'S

conclusionsThe continuous subcuticular technique of perineal repair may be associated with less pain in the immediate postpartum period than the interrupted suture technique. The long-term effects are less clear.
