We examined the hemodynamic effects of congesting cuffs (rotating tourniquets) in 12 patients with first acute myocardial infarction and new onset of congestive heart failure 24 to 48 hours after admission. Congesting cuffs were applied for two periods of 15 minutes each, 15 minutes apart, and inflated to 30 mm Hg and 60 mm Hg consecutively. No change was noticed in mean pulmonary artery wedge pressure, which was 20 +/- 3 mm Hg at the beginning of the study and 19 +/- 3 mm Hg at the completion (P greater than .05, NS), nor in other hemodynamic and blood gases parameters. Patients' clinical conditions remained unchanged. We conclude that application of congesting cuffs at pressures of 30 mm Hg and 60 mm Hg does not result in any change in clinical or hemodynamic data in patients with acute myocardial infarction and new onset of congestive heart failure.
我们对12例首次发生急性心肌梗死且在入院后24至48小时出现新发充血性心力衰竭的患者，研究了充血袖带（旋转止血带）的血流动力学效应。充血袖带分两个阶段应用，每个阶段15分钟，间隔15分钟，依次充气至30毫米汞柱和60毫米汞柱。平均肺动脉楔压未见变化，研究开始时为20±3毫米汞柱，结束时为19±3毫米汞柱（P大于0.05，无显著性差异），其他血流动力学和血气参数也无变化。患者的临床状况保持不变。我们得出结论，对急性心肌梗死和新发充血性心力衰竭患者应用30毫米汞柱和60毫米汞柱压力的充血袖带，不会导致临床或血流动力学数据发生任何变化。
