Muscle perfusion in the horse

Abstract
Muscle perfusion was studied in conscious and anesthetized horses by monitoring the clearance of a locally injected bolus of saline containing 133Xe. The mean of all the measurements made from the branchiocephalicus and semimembranosus muscles in conscious subjects was 1.29 ml/min per 100 g, while in anesthetized subjects it was 0.40 ml/min per 100 g. The significance of these results is discussed in relation to the clinical occurrence of post-anesthetic myositis.
