Effect of dressings on saphenous vein harvest incision pain, distress and cosmetic result

Abstract

Little research has examined the healing and pain associated with saphenous vein (SV) harvest incisions, and no literature has addressed the associated distress and cosmetic result. The purpose of this study was to determine whether dry sterile gauze dressings, transparent film dressings or no dressings were more effective in hospitalized patients undergoing coronary artery bypass graft (CABG), in terms of minimizing leg incisional pain, minimizing the distress of a leg scar and improving the cosmetic appearance of the leg incision scar. Patients were randomized to dressing type on postoperative day (POD) 1, completed a pain and distress visual analogue scale (VAS) on PODs 1, 3 and 5, and a cosmetic result VAS upon discharge. Overall, leg incisional pain decreased over time (p < 0.05). Females reported decreasing pain between PODs 1 and 3, while males reported increasing pain between PODs 1 and 3 (p < 0.05). The film-dressing group reported decreasing pain from PODs 1 to 3, while the no-dressing and gauze-dressing groups reported increasing pain from PODs 1 to 3 (p < 0.05). Pain on POD 5 was positively correlated with an unfavorable cosmetic result (r = 0.42, p < 0.05), and distress on POD 5 was positively correlated with an unfavorable cosmetic result (r = 0.44, p < 0.05). The results of this study are encouraging and support the continued testing of dressings to minimize pain and distress, as well as enhancing cosmetic result.
