Comparison of suture material and technique of closure of subcutaneous fat and skin in caesarean section.

BACKGROUND

A large number of women undergo caesarean section throughout the world. These women pass through a period of post operative pain and a morbidity period. These women translate into a substantial portion of population and hence there is a load on the financial resources of healthcare system. Use of the appropriate technique to approximate the wound after caesarean section would not only avoid financial load but also help in early recovery of the patient.

OBJECTIVE

The aim of this study is to compare the effects of alternative techniques for closure of subcutaneous fat and skin on maternal health and use of healthcare resources in caesarean section.

METHODS

Patients undergoing Caesarean section were divided in two groups of one thousand patients each. Patients with hematological disorders or a malignancy, diabetes, septicemia or chorioamnionitis were excluded from the study. In all the patients, after stitching the uterus, the rectus sheath was stitched with thread vicryl No.1 (synthetic absorbable braided sutures with polyglycolic acid, polycaprolactone and calcium stearate coating), using a round body needle. Then the patients were divided into two groups. In group I, vicryl No.1 thread used in stitching of the rectus sheath was continued into the skin with application of subcuticular stitches, after securing the edges with a knot. In group II, after stitching the rectus sheath with vicryl No. 1, the thread was cut and interrupted sutures were applied in subcutaneous fat with thread vicryl No. 2. Skin was stitched with subcuticular stitches using proline 2, a non-absorbable propylene suture. The two groups of patients were observed for the duration of surgery, post-operative pain in stitches, patient satisfaction about removal of stitches, evidence of wound infection or seroma, and cosmetic results.

RESULTS

It was noted that the duration of surgery in group I was on average 7.5 minutes less as compared to the duration in group II. Patients in group I were more satisfied with the results of the surgery and were relieved to know that their stitches did not need to be removed.

CONCLUSIONS

Although no difference was found in the rates of wound infection and formation of scar tissue between the group I and group II, the duration of surgery was less and the patients were more satisfied in group I.
