Effects of Early Versus Delayed Excision and Grafting on Restoring the Functionality of Deep Burn-Injured Hands: A Double-Blind, Randomized Parallel Clinical Trial

Abstract

Hand burns have major impacts on daily activities. An interdisciplinary and multifaceted approach is necessary to effectively treat these burns. Generally, hands are common sites for burn injuries. It is known that Early Excision and Grafting (EEG) of deep burn wounds can decrease scar and subsequent contracture formation compared with Delayed Excision and Grafting (DEG) method. Accordingly, this study aimed to compare the effects of these procedures on function of hands with deep burns, by using the Michigan Hand Questionnaire (MHQ). In this double-blind randomized clinical trial, we evaluated a total of 50 patients (age range: 15-70 years) with deep second-degree burns of both hands from January 2013 to December 2015. The subjects were randomly divided into two groups, treatment (EEG) and control (DEG) groups (25 patients per group). They followed up postoperatively for 3 months. MHQ was completed for each of them to determine the function of the hands, pain sensation, limitation of daily activities, overall satisfaction, and cosmetic appearance during follow-up. Data were analyzed in the groups using SPSS version 16. Baseline characteristics of the groups were matched. In early postoperation, hand functions and daily activities, gross appearance, and pain sensation were better in EEG group. After 1 and 3 months, no significant difference was detected between the groups except for patient satisfaction which was better in EEG group. Also, EEG group was associated with a significant shorter hospital stay and lower treatment costs compared with DEG group. Graft take rate was similar in both groups. EEG is recognized as the standard treatment for deep skin burns, but we did not find any significant difference between effects of EEG and DEG on hand functions although EEG group had shorter hospital stay and lower treatment costs compared with DEG. The main goal of treatment of hand burns is restoration of the hand functions. Based on our findings, hand function was not related to the type of surgery. Also, as all wounds in both surgical groups healed less than 3 weeks, the authors suggest that the excision time limit could be change in our burn center from 10 days to 2 to 3 weeks when we use sheet graft as for hands.
