Improved Intraoperative Hemodynamics in Burn Surgery: An Institutional Change to Pediatric-Specific Hemostasis...

A cornerstone of burn surgery hemostasis is infiltration of tumescent vasopressor solutions and topical vasoconstrictor-soaked compresses. Studies detailing pediatric-specific concentrations of these solutions are lacking. Our aim was to assess hemodynamic changes after an institutional change in tumescent vasopressor solution and vasopressor-soaked topical compresses for hemostasis management during pediatric burn surgery. Once the institutional change was implemented, cases performed before and after the intervention were reviewed; inclusion criteria included age 0 to 18 years, burn TBSA ≥ 10%, and surgery length > 50 minutes. Primary outcomes included changes in intraoperative mean arterial pressure, maximum inhaled anesthetic concentration, need for direct-acting vasodilators, estimated blood loss, and need for blood transfusions. Thirty patients were included in the intervention group, and 31 in the control group. There was a significant difference in peak intraoperative blood pressure in the intervention group (21.4%) compared with the control group (48.0%, P = .005). Maximum inhaled anesthetic concentrations were lower in the intervention group (2.5% vs 2.8%, P = .02). Estimated blood loss per TBSA decreased significantly (8.2 ml/1% TBSA vs 1.7, P = .008), as well as blood transfusion rates, with a transfusion rate of 16.7% in the intervention group vs 45.2% in the control group (P = .03). The changes instituted in type and concentration of tumescent solution and vasopressor-soaked topical compresses were associated with improved hemodynamic changes and decreased transfusion rates intraoperatively.
