摘要
目的:分析体外循环术后长期机械通气治疗患者的预后因素。方法:回顾分析60例体外循环术后长期机械通气治疗患者的临床资料,分析转流时间、机械通气时间、病种与治疗失败比例之间的关系;统计失败病例心外脏器功能障碍频数与分布。结果:治愈组与失败组间转流时间有显著差异(P<0.05);机械通气时间存在极显著差异(P<0.01),两者之间正相关。病种与失败比例无明确联系(P>0.05)。失败病例功能障碍的心外脏器或系统依次为肺、肾、脑、胃肠、代谢、肝。结论:体外循环术中转流时间延长、术后机械通气时间延长提示预后不良,这与病种无明确关系。单纯心、肺功能不全者预后良好,心、肺功能不全合并肺出血、肺部感染或者第二脏器功能不全者愈后不良。
Objective To analyze the factors influencing the prognosis of the patients undergoing long-term mechanical ventilation (LTMV) after cardiac pulmonary bypass (CPB). Methods The clinical data of 60 patients, who underwent LTMV after CPB, were reviewed and The relationships between the factors including CPB time, mechanical ventilation (MV) lime and the disease category,and the lost rate were analyzed. The frequency and distribution of failure organs except heart in the lost cases were also calculated. Results There were significant difference ( P<0.05) in CPB timeand very significant difference ( P<0.01) in MV time between the suceessful group and the lost group. CPB time was positively correlated with MV time. The lost rate was little related with the disease category. The common faiure organs or systems except heart in the lost cases in turn were the lung, kidney, brain, gastrointestines, metabolism and liver. Conclusions The prolonged CPB time during the operation and MV time after the operation suggest that the prognosis is bad. The prognosis is good in patienes only with heart or lung dysfunclion,but it is bad in the paeients with heart and lung dysfunctions accompanied with pulmonary hemorrhage, pulmonary infection or another organ dysfunction.
