摘要:
The haemodynamic effects of hyoscine‐N‐butylbromide (0.30 mg/kg, intravenously) were studied in eight adult ponies in a blinded two‐period crossover experiment with repeated measures. Values for heart rate were 63%, 48% and 13% greater than control values at 1, 16 and 46 min, respectively, after administration of hyoscine‐N‐butylbromide. Cardiac output increased by 16% at 16 min after drug injection. Mean right atrial pressure was decreased by 79%, 63%, 45% and 52% at 1, 16, 46 and 61 min, respectively, after drug administration. Stroke volume was decreased by 32% at 1 min and pulmonary arterial wedge pressure was decreased by 44% at 16 min. We detected no significant difference in mean systemic arterial pressure, mean pulmonary arterial pressure, systemic vascular resistance or pulmonary vascular resistance at
