IntroductionIn lieu of limited studies on the timing of burn wound eschar excision for burns, a more comprehensive analysis is indicated to determine the effects of early wound excision following burns. This study aims to address the outcomes of early wound excision in burn patients.MethodsData collection were from TriNetX research database. Three groups of burn patients were stratified by the number of days in which they received burn wound excision within 14 days of injury. Five outcomes were observed: death, wound infection, sepsis, myocardial contractile dysfunction, and blood transfusion. Risk and incidence of various health outcomes were compared between the groups after propensity-matching age, sex, ethnicity, race and burn size using a z-test with p < 0.05 considered significant.ResultsWe identified 6158 burn patients with wound excision within 14 days of injury, the majority of whom (60.1%) received burn wound excision between 0 and 3 days after burn. 72.5% of patients had burns covering less than 20% of total body surface area. After propensity matching, we found a significantly lower risk of mortality in those who received burn wound excision within the first three days (3.84%) as compared to 8-14 days after burn (6.09%) (p < 0.05). Moreover, we found a decreased risk of wound infection in patients with burn wound excision within 0-3 days (37.84%) compared to those 4-7 days (42.48%) (p < 0.05). No statistical difference was detected in propensity-matched groups for myocardial contractile dysfunction, blood transfusion, or sepsis. In addition, the risk of hypertrophic scaring significantly decreased when wound excision was performed within 0-3 days (22% within 0-3 days, 28% within 4-7 days, p < 0.05).ConclusionBurn wound excision within 3 days of injury is beneficial when comparing to later treatment between 4 and 14 days, which results in a significantly lowered risk of mortality and infection in burn patient.Copyright © 2023 Elsevier Ltd and International Society of Burns Injuries.
