Objective To observe the application effect of "trinity" synergistic emergency in the cure and treatment of children with fulminant myocarditis (FM).

Methods Clinical materials of FM children with routine emergency nursing (control group) and FM children with "trinity" synergistic emergency (observation group) were retrospectively analyzed, with 42 cases in each group. The complications, weaning rate of extracorporeal membrane oxygenation (ECMO), mortality, myocardial injury markers (aspartate aminotransferase and lactate dehydrogenase) and cardiac function (left ventricular ejection fraction) before and after intervention were compared between the two groups, and the satisfaction degree to nursing of family members in both groups was investigated.

Results The total incidence rate of complications in the observation group was lower than that in the control group (P < 0.05), while the weaning rate of ECMO was higher than that in the control group (P < 0.05); after intervention, serum levels of aspartate aminotransferase and lactate dehydrogenase in both groups were lower than those before intervention, and the levels of the two indexes in the observation group were significantly lower than those in the control group (P < 0.05); the left ventricular ejection fraction in both groups was significantly higher than that before intervention, and the index in the observation group was higher than that in the control group (P < 0.05); the satisfaction degree to nursing of family members in the observation group was significantly higher than that in the control group (P < 0.05).

Conclusion For children with FM, "trinity" synergistic emergency can reduce the complications, increase the weaning rate of ECMO, improve the myocardial injury and cardiac function, and increase the satisfaction degree to nursing of family members.
