COMPARISON OF SINGLE AND DOUBLE LAYERED SAPHENECTOMY WOUND CLOSURE TECHNIQUES IN CORONARY ARTERY BYPASS GRAFT SURGERY (CABG) USING ASEPSIS WOUND SCORE

Abstract

Objective: To compare the mean ASEPSIS wound scores in single-layer versusdouble-layer closure of below-knee saphenectomy wound at 5 postoperativeday in coronary artery bypass graft surgery patients.

Methodology: This randomized controlled trial was conducted at Department ofCardiac Surgery, Dow University of Health Sciences and Civil Hospital Karachifrom January to June 2017. Patients of either gender with age of 50-60 yearshaving multi-vessel coronary artery disease undergoing elective, isolated CABGwith ejection fraction greater than 40% and controlled diabetes and hypertensionfor more than 5 years were included in the study . Patients were randomlyassigned to two groups (Single layer closure and Double layer closure).Woundswere examined and scored (using ASEPSIS scoring system) by consultant on 5postoperative day.

Results: A total of 80 patients were included in the study . Patients were divided intwo groups (S= Single layer closure and D= Double layer closure ) having 40patients each. The mean age was 54.9 3.31 years. About 77.5% of patientswere males. Mean ASEPSIS score in group S was 3.10 1.02 while in group Dwas 5.68 1.30 (p<0.05).

Conclusion: Compared with double-layer, single-layered technique has lowermean ASEPSIS score in saphenectomy wounds of CABG surgery patients andhence is more suitable modality of saphenectomy wound closure.
