To summarize the nursing experience of one case of idiopathic scoliosis complicated with malignant hyperthermia after operation. It aimed at the problems of how to recognize and treat malignant hyperthermia，how to manage body temperature and end-expiratory carbon dioxide partial pressure，how to use dantrolene sodium correctly and avoid the development of rhabdomyolysis. We controlled body temperature as early as possible，continuously monitored core body temperature and end-expiratory carbon dioxide pressure，used dantrolene sodium rationally， monitored creatine kinase and implemented alkalization of urine and other measures. After 11 days of treatment and nursing，the patients were successfully removed from the ventilator and transferred back to the ward for treatment. He was discharged successfully 20 days after the operation. He was followed up for 3 months after discharge and his condition was good.
