Abstract:BackgroundPostoperative pain at skin graft donor sites is frequently undertreated in burn patients, which can impair reconstructive outcomes and result in harmful psychological consequences. We find a critical need to explore and promote non-opioid, multimodal analgesics. Donor site infiltration of the local anesthetic liposomal bupivacaine in adolescent and young adult burn patients has not been previously investigated. Therefore, the goal of this study was to evaluate intraoperative liposomal bupivacaine infiltration for postoperative donor site pain control in adolescent and young adult burn patients undergoing reconstructive skin graft procedures.MethodsThis retrospective analysis included patients aged 14–25 years, who underwent at least two reconstructive skin graft procedures, one that received donor site infiltration of the standard treatment (bupivacaine hydrochloride) and one that received donor site infiltration of liposomal bupivacaine. The final sample included 30 patients with a total of 44 liposomal bupivacaine cases and 53 standard treatment cases analyzed.ResultsIn the authors’ five-year experience, the use of liposomal bupivacaine compared to standard treatment was associated with statistically significant decreases in 0–4 h postoperative pain scores (mean 1.4/10 versus 2.3/10, p = 0.04) and 0–24 h postoperative pain scores (mean 1.7/10 versus 2.4/10, p = 0.02). Neither analgesic was associated with adverse events. Differences in length of stay and inpatient postoperative opioid usage were not regarded as significant.ConclusionIn this retrospective analysis, the authors report the first results that suggest intraoperative liposomal bupivacaine donor site infiltration may be associated with statistically improved patient outcomes in adolescent and young adult burn patients. However, the reported differences are most likely not clinically significant, establishing the necessity for further evaluation of using liposomal bupivacaine in this unique patient population.
