COMPARISON BETWEEN ADRENALINE AND WITHOUT ADRENALINE SOLUTION ON BLEEDING CONTROL OF SKIN GRAFT DONOR SITE: A RANDOMIZED CONTROLLED TRIAL

Abstract

OBJECTIVE: To compare the bleeding control of skin graft donor site between normal saline soaked gauze with adrenaline and conventional technique having no adrenaline. METHODS: This open-label randomized control trial was conducted at Dr. Ruth K.M. Pfau Civil Hospital, Karachi, Pakistan from October 2020 to March 2021. Seventy-five patients were randomized to interventional (n=36, 48%) and control group (n=39, 52%) through sealed envelopes. Diluted solution was prepared by adding 30cc of Ringer’s lactate and 10cc of lignocaine 2%, with 1cc of adrenaline of 1:200000 with 200 ml of normal saline solution. Solution for control group was containing only normal saline. Following the skin harvesting at donor site, a gauze piece soaked with tumescent solution was applied at the donor site wound. Bleeding severity and epithelialization were assessed. Data was recorded in a pre-designed performa and analyzed through SPSS version-25. RESULTS: There was no significant differences in baseline characteristics like age (p=0.823), gender (p=0.984) and nature of injury (p=0.936) among two groups. Severe, moderate and mild bleeding was noted in 20/39 (51.3%), 15/39 (38.5%) and 4/39 (10.3%) cases in control group as compared to 0/36 (0%); 2/36 (5.6%) and 25/36 (69.4%) cases in interventional group respectively (**<0.001). No bleeding was noted in 9/36 (25%) cases of interventional group. Complete epithelialization was observed in 24/36 (66.7%) & 17/39 (43.6%) cases in adrenaline and control groups respectively (p=0.045). CONCLUSION: Application of adrenaline was more effective in bleeding control and early epithelialization at donor site following the skin harvesting as compared to conventional technique.
