Suspected Malignant Hyperthermia: a Case Report

Main Article Content

Varisara Charoenyingpaisal


We described a patient who developed probable malignant hyperthermia after receiving succinylcholine and sevoflurane. An explore-laparotomy for a right ovarian cystectomy was performed under general anesthesia on a 30-year-old Thai woman who had never previously had anesthesia. She developed tachycardia after receiving succinylcholine and sevoflurane, as well as an unexpected increase in ETCO2 and body temperature. Respiratory and metabolic acidosis was also evident. Rhabdomyolysis was suspected due to dark brownish urine and apparently high creatine phosphokinase. The clinical presentation was used to make a diagnosis of malignant hyperthermia. This patient received supportive and symptomatic care without the use of dantrolene. Finally, the outcome was satisfying since it was rapidly recognized and handled.
