title: Anesthesia in malignant hyperthermia susceptible patients.
abstract: The intra- and postoperative course of 30 general and 3 regional anesthetics in 27 MH-carriers verified by in vitro contracture tests is reported. None of the patients received dantrolene prophylactically. Disposable tubings were used for ventilation, vaporizers and soda lime were removed. ECG, esophageal temperature, blood pressure, oxygen saturation, and end tidal pCO2 were monitored. Minor tranquilizers were offered for premedication. Fentanyl, thiopentone, nitrous oxide, non depolarizing relaxants, neuromuscular antagonists and naloxone were used. In three patients, surgery was performed during epidural or spinal anesthesia with the use of amide local anesthetics. Neither MH-related changes in perioperative heart rates, body temperatures, and CK levels nor any other symptoms of MH were observed in any patient. The anesthetic techniques used seem to be safe and reliable; the anesthetic management of known MHS patients is discussed in detail.
