Abstract:
Objective To review multi-center experience on rescue use of extracorporeal membrane oxygenation(ECMO) in pediatric patients with acute fulminant myocarditis and to investigate its short-term outcome in China.Methods The survey was conducted in 28 tertiary hospitals in China mainland.All children<18 years who had been supported with non-open chest ECMO to rescue acute fulminant myocarditis in PICU were reviewed.Results Twenty-three of 63 patients with ECMO support were diagnosed acute fulminant myocarditis.Their mean age was(86.3±48.8)months,mean weight was(25.8±12.1)kg,and mean left ventricular ejection fraction was(39.5±15.6)%.Eighteen patients(78.3%) survived to discharge and 5 cases(21.7%) died.The average length of ECMO was(119.1±57.3)h,(110.6±42.7)h for survival,(150.0±93.8)h for nonsurvival.There was no statistically difference between survival and death in ECMO support time(P=0.41).The mean arterial pressure increased from(60.7±23.7)mmHg(1mmHg=0.113kPa) of the beginning to(72.1±9.8)mmHg at 24h after ECMO treatment,and increase of mean arterial pressure was higher in the survival compared with the nonsurvival(P=0.04).The mean serum lactate decreased from(6.8±5.1)mmol/L at ECMO initiation to(2.9±2.6)mmol/L at 24h after ECMO treatment,and decrease of serum lactate was higher in survival group compared to nonsurvival group(P<0.001).Twenty-one patients(91.3%) were decanulated from ECMO successfully.Three patients died within 30 days after ECMO support,and eighteen patients survived to hospital discharge.The overall survival rate was 78.3%.There were no significant difference between the death and the survival in ECMO support time(P=0.41) and medical cost(P=0.24).The most common complications during ECMO were bleeding and disfunction of oxygenator.Of the 18 survivors,15 were followed up,4 experienced obvious sequelae,and 2 had neurologic issues.Conclusion ECMO is an effective hemodynamic support treatment that confers better clinical outcome for pediatric patients with acute fulminant myocarditis.
