Abstract:
Objective To review multi-center experience on rescue use of extracorporeal membrane oxygenation(ECMO) in pediatric patients with respiratory failure and to investigate its short-term outcome in China.Methods The survey was conducted in 4 tertiary hospitals in China mainland.All children<18 years old who had been supported with non-open chest ECMO to rescue respiratory failure in PICU were reviewed.Results Twenty-one patients with ECMO support were diagnosed respiratory failure.Male was 14,female was 7.Twelve patients successfully weaned off ECMO, 8 patients survived to discharge and 13 died.The largest part of protopathy was severe pneumonia(33%)and acute respiratory distress syndrome(29%).Their mean age was 29.0(9.0,81.5)months, mean weight was 12.0(9.0,20.8)kg,and mean OI index was 31.5(19.2,41.0).The average length of ECMO run was 149.0(91.2,242.0)hours.The blood gas analysis showed that PO2 increased from 49.5(40.4,61.9)mmHg(1mmHg=0.133kPa) at the beginning to 65.0(42.6,120.5)mmHg at 24h after ECMO treatment,and the increase of PO2 was higher in the survival compared with the nonsurvival[52.0(1.8,89.4) mmHg vs.8.2(-15.1,33.9) mmHg,P=0.036].The SO2 increased from 80.0%(70.4%,91.8%)at ECMO initiation to 98.0%(95.6%,100%)at 24h after ECMO treatment,and increase of SO2 was higher in survival group compared to that of nonsurvival group[23.5%(11.4%,27.1%) vs.4.3%(2.4%,23.8%),P=0.039].VV mode had higher survival rate than VA mode(3/3 vs.5/18).The longer the use of ventilator before ECMO,the mortality rate increased as well.The mechanical ventilation time before ECMO was significantly longer in nonsurvival group than that in the survival group[4.5(2.5,12.0)h vs.1.6(1.0,2.2)h,P=0.015].The most common complications during ECMO run were bleeding and disfunction of oxygenator.Conclusion ECMO is an effective support treatment for the pediatric patients with respiratory failure,which significantly improves oxygenation.
