Is the Use of Routine Echocardiograms Warranted in Large Pediatric Burns?

Abstract

Cardiac dysfunction can develop in large pediatric burns during the acute and recovery phase. When occurring in this population, the cardiac abnormality appears as left ventricular dysfunction or dilated cardiomyopathy. Recent studies have demonstrated perioperative and long-term cardiac dysfunction resulting in longer hospital stays for patients over 40% total body surface area. The objective of this study was to assess if early use of echocardiograms in large burns would allow for early recognition of patients at risk for cardiac dysfunction. Pediatric burn patients ages 0 to 18 years who sustained a burn injury of 30% TBSA or more or developed cardiac dysfunction during hospital course were evaluated. Echocardiograms were obtained upon admission with monthly repeats until three normal studies were attained or the patient was discharged and when symptomatic. Of the 130 acute burn patients admitted during 7/2017 to 10/2018, 10 patients met criteria for enrollment in this study. The average age was 5 years (0.8–10 years), 70% were males and 90% sustained flame injuries.Total TBSA average was 45% (24–70%) with average full-thickness burns of 33% (0–67%). Twenty echocardiogram studies were obtained. One patient with 25% TBSA burn, demonstrated severe left ventricular dysfunction with an ejection fraction (EF) of 25% from post-arrest myocardial stunning. Repeat echocardiogram studies demonstrated full recovery with normal EF. The remaining patients, despite large TBSA injuries, did not exhibit any abnormalities on echocardiogram examinations. No cardiac interventions were required. Use of echocardiograms is best performed on symptomatic burn patient populations.
