To summarize the nursing experience of a child who developed ventricular fibrillation storm after cardiac valve replacement surgery and was successfully treated by extracorporeal cardiopulmonary resuscitation. In critical situations where defibrillation was repeated and drug therapy was ineffective，the emergency team for extracorporeal membrane oxygenation after cardiac surgery was quickly activated to implement cardiopulmonary resuscitation. Subsequently，targeted temperature management，neuroprotective strategies，and goal-directed analgesia and sedation protocols were implemented. Through multidisciplinary team collaboration and meticulous nursing care，the child was successfully liberated from ECMO on postoperative day（POD） 7. He was transferred from ICU to the cardiac surgery on POD 12，and was discharged on POD 19. The follow-up showed good prognosis.
