摘要
目的:评价主动脉内球囊反搏(IABP)在心脏手术后救治低心排血量(低心排)的效果。方法:28例术后应用中等剂量心脏活性药物支持不能改善的低心排患者,均立即使用KAATPlusIABP(40ml)。监测桡动脉和主动脉压力波形,持续监测左心功能,记录尿量,观察末梢循环状况。结果:全组患者IABP辅助时间为(48±32)h,早期生存率为75.0%。所有患者在应用IABP后,桡动脉压力(基础收缩压)均在早期有所下降(P<0.01);基础舒张压上升(P<0.01);平均动脉压增加;尿量明显增加,术前2例肌酐水平高的患者20h后恢复正常;持续左心功能监测结果见CO、CI于应用IABP后2h明显恢复,48h已经恢复到术前水平,MAP于应用后即明显提高,外周阻力明显降低。结论:IABP对救治心脏手术后低心排起到了重要作用,大大降低了死亡率。
Objective: To evaluate the clinical experience of low cardiac output (CO) following cardiac surgery with CPB during intra aortic balloon counterpulsation(IABP). Methods: The patients were used KAATⅡplus IABP(40 ml), that standard is if used medium of dosage medicines following low CO can't perfect, then used IABP at once. The patients were arterious waveform was calculated, and continuous cardiac output monitor in 28 patients after IABP. The changes of hemodynamic parameters and urine were recorded. Results: The IABP time was (48±32) h in all patients. Early stage of live rate is 75.0%. Arterious pressure decreased, while diastolic pressure increased significantly ( P <0.01). The CO and Cardiac index(CI) were also markedly increased immediately after applying IABP and recovered to the preoperative level 48 hrs after IABP. Conclusion: The clinical experience of low CO following cardiac surgery with CPB during IABP is very important, mortality rate is decreased.
