Abstract

Severe cardiac insufficiency resistant to drug therapy developed in the immediate post-perfusion period in 1.5-2% of cardiosurgical patients who underwent operation in the recent 8 years. In view of this, such a method of mechanical sustenance of the weakened heart as left-ventricular bypass (LVB) was suggested. LVB lasting 5.7 hours on average, was carried out in 56 patients in the immediate postperfusion period in adequately corrected heart valvular disease. It was shown that by unloading the left ventricle by means of a roller pump the average arterial pressure can be raised, the average left-ventricular pressure lowered, and the dose of the administered cardiotonics reduced. All this contributes to the restoration of the patient's own adequate circulation. Owing to LVB, cardiac activity was restored in 56% of patients, 41% of patients recovered and were discharged from the hospital. The results bear evidence that LVB is an effective method for sustenance of circulation in cardiosurgical patients.

[心脏外科患者左心室搭桥治疗急性心功能不全]。
在近8年接受心脏外科手术的患者中,1.5-2%的患者在灌注后立即出现严重的心功能不全,对药物治疗产生耐药性。鉴于此,建议采用左心室旁路(LVB)作为机械维持虚弱心脏的方法。56例经充分纠正的心脏瓣膜疾病患者在灌注后立即进行LVB,平均持续5.7小时。结果表明,通过滚轴泵卸载左心室,可以提高平均动脉压,降低平均左心室压,并减少给药剂量。所有这些都有助于恢复病人自身的充足循环。由于LVB, 56%的患者心脏活动恢复,41%的患者康复出院。结果表明,LVB是一种有效的心脏外科病人维持循环的方法。
