摘要
目的 :回顾我院 1 6例小体重先天性心脏病患儿的体外循环 (CPB)状况 ,总结其灌注技术。方法 :对我院 1 995～ 1 996年的 1 6例小体重先天性心脏病患儿临床资料及CPB情况(人工心肺机类型、预充液组成、CPB操作步骤、CPB时间、升主动脉阻断时间、心肌保护等 )做一回顾性总结。结果 :1 6例患儿。年龄 5个月～ 2岁 ,平均 1 2岁 ;体重 4 5～ 9 5kg ,平均8 2kg。CPB时间 32～ 2 84min(平均 92min) ,升主动脉阻断时间 1 4～ 1 2 1min(平均 6 4min)。冷晶体高钾停搏液经滚压泵自主动脉根部间断灌注较好的保护了心肌。结论 :适宜的血液稀释 ,根据不同疾病选择正确的灌注方法 ,良好的术中管理及心肌保护 ,可有效的使小体重先天性心脏病患儿在CPB中平稳过渡 。
Objective:To review the situation of CPB of light body weight children who suffered from congenital heart disease (CHD) and summarize the perfusion techniques.Methods:The data of 16 CHD children with light body weight were reviewed respectively including clinical and CPB materials from 1995 to 1999.The patients' age were from 5 months to 2years and body weight were 4.5～9.5kg(1.2 year and 8.2kg in average).CPB time were from 32～284min and blocking time were 14～121min (92 and 64 min in average).The cold crystal cardioplegia was pumped into the root of aorta interrupted that could protect myocardium perfectly.Conclusion:The available bloody dilution,correct perfusion methods and good management in operation and myocardium protection could reach safe effect and reduce complications and mortality.
