[Malignant hyperthermia in swine: a study of atracurium in MH-susceptible swine].
Since muscle relaxants have been implicated in triggering malignant hyperthermia (MH) in MH-susceptible humans and animals, the potential of new muscle relaxants for triggering MH needs to be assessed in vivo in MH-susceptible pigs. The triggering potential of atracurium was evaluated in six MH-susceptible pigs during one hour infusion of a 90% blocking dose (0.4 mg/kg/h) of atracurium. ⋯ Rectal temperature decreased slightly (36.4 to 35.6 degrees C) and end tidal CO2 was stable at 5.46 kpa. In this study atracurium did not trigger MH in susceptible pigs.
