ABSTRACT
Fluid creep occurs when resuscitation after extensive burn injury reaches volumes higher than predicted. Since this has been described in patients with high opioid requirements, continuous analgesics and sedatives, including dexmedetomidine, have been avoided during resuscitation. This study sought to describe the impact of dexmedetomidine on fluid resuscitation requirements. This retrospective cohort study included adult patients with burns greater than 20% total body surface area (TBSA) resuscitated between January 2017 and June 2022 at a regional burn center. Patients deceased within 48 hours of burn were excluded. The primary outcome was volume of fluid required in the first 24 and 48 hours postburn. Secondary outcomes were the incidence of fluid-related adverse events within 7 days postburn. A total of 170 patients were included 55 in the dexmedetomidine cohort and 115 in the control cohort. After propensity matching for variables associated with fluid creep, the dexmedetomidine cohort required 4.2 ± 1.7 mL/kg/%TBSA in the first 24 hours compared to 3.6 ± 1.1 mL/kg/%TBSA in the control cohort (P = 0.03). The difference was no longer significant at 48 hours (P = 0.11). There were no differences in the incidence of acute respiratory distress syndrome, delayed escharotomy/fasciotomy, intra-abdominal hypertension, or renal replacement therapy. Dexmedetomidine exposure during acute resuscitation resulted in increased fluid requirements in the first 24 hours, suggesting it is independently associated with fluid creep; however, this increase was not sustained at 48 hours. Clinical significance of this finding is unclear, as there was no increase in adverse events related to excessive fluid resuscitation between cohorts.
