case report of malignant hyperthermia following to the administration of succinyl choline and halotan in a patient with previous non complicated surgery with halotan

ABSTRACT

Malignant hyperthermia is amongst the most life-threatening complications of surgery. The most classical type occurs following to the administration of agents used for induction of anesthesia. The patient was 56 years old male being scheduled for Tympanomastoidectomy due to chronic otitis media. Induction of anesthesia was performed via Thiopental sodium, Fentanyl, Succinyl choline and lidociane. After 75 minutes of induction of anesthesia, the patient experienced increase in blood pressure, heart rate, body temperature, acid-base and electrolyte impairment being suggestive of malignant hyperthermia. Regarding to its life-threatening feature, the occurance of malignant hyperthermia is probable during surgery even in patients with previous non-complicated surgeries. Therefore, continuous monitoring, and appropriate history, early diagnosis and reduction of side effects are necessary
