Abstract: Summarize the emergency care experience of severe heart stroke in a 6-year-old child who was left in a closed car carriage. To solve the major problems such as thermal asphyxia,body fluid loss,repeated febrile convulsions,we implemented combined cooling technology,continuous core temperature monitoring,target-oriented capacity management to maintain the balance of water,electrolyte and acid-base,the management of artificial airway to effectively keep the airway unobstructed,case of repeated convulsive seizures,and family participatory care. After 6 h of emergency multidisciplinary emergency treatment and precision care,the child was successfully transferred to the emergency intensive care unit for further treatment,and later transferred to the other hospital for rehabilitation treatment. After a follow-up of one month,the child had a good prognosis.
