title: Effect of halothane on isometric contractile properties of muscle from stress-susceptible and stress-resistant pigs.
abstract: The effect of clinical concentrations of halothane on the isometric contractile properties of muscle in stress-susceptible and stress-resistant pigs was studied. Exposure to halothane initially increased the percentage of peak twitch tension in the muscle of stress-susceptible pigs whereas the tension gradually decreased in the stress-resistant group of pigs. Halothane may act as a potentiator of muscle contraction in stress-susceptible animals, but this effect is transitory.
