Cardiovascular measurements were made in 12 children in whom arterial hypotension was induced with pentolinium and halothane. Propranolol was given to five patients who exhibited tachycardia. Measurements were made at the following stages: before induction of hypotension, 5 min after the administration of pentolinium, when a "dry" opening field was obtained, at the time of maximum hypotension and when arterial pressure had returned to 90% of the control values. The decrease in arterial pressure 5 min after the administration of pentolinium was accompanied by tachycardia, but there was no significant change in cardiac index and the operative field was congested. A substantial decrease in cardiac output occurred when a "dry" field was obtained.
对12名使用潘托铵和氟烷诱发动脉低血压的儿童进行了心血管测量。给5名出现心动过速的患者使用了普萘洛尔。在以下阶段进行测量：诱导低血压前、给予潘托铵后5分钟、获得“干燥”手术视野时、出现最大低血压时以及动脉压恢复到对照值的90%时。给予潘托铵后5分钟动脉压下降伴有心动过速，但心脏指数无显著变化，且手术视野充血。获得“干燥”视野时心输出量大幅下降。
