【摘要】 目的 :探讨肺切除术后并发心律失常的原因。方法 :5 6 2例肺切除术后发生心律失常与年龄、术式、术前肺功能检测、术后血气分析的影响。结果 :5 6 2例术后并发心律失常 10 4例 (18.5 % ) ,年龄大于 70岁 ,全肺切除术分别占 38.77%及2 7.72 %。FEV1<5 0 % ,MVV <5 0 % ,FVC <5 0 %分别占 6 7.2 7%、4 6 .5 3%及 6 7.93%。术后 2 3例血气分析PO2 <6 0mmHg ,CO2 >4 5mmHg ,SO2 <0 .96 ,2 1例发生心律失常。后经气管切开 ,积极纠正缺氧 ,3天内心律失常消失。本组死亡 4例 (3.84 % )。结论 :全肺切除 ,大于 70岁 ,FEV1、MVV及FVC <5 0 % ,明显缺氧易诱发心律失常。更多还原

【Abstract】 Objective:To analyze the reasons of complicated arrhythmia after resection of lung. Methods:The relation of arrhythmia with age, operation mode,preoperative lung function and postoperative blood gas of 562 cases of lung resection were analyzed. Results:There were 104 of 562 cases (18.5%) complicated with arrhythmia postoperatively. 38.77% of them were older than 70 years. 27.72% had operation of pneumonectomy.The parameters of FEV 1,MVV,FVC lower than 50% were 67.24%,46.53% and 67.93% respectively.Postoperative blood gas analysis of the 23 cases showed that Po 2 was lower than 60 mmHg,Pco 2 was higher than 45 mmHg,So 2 was lower than 96%.21 of them developed postoperative arrhythmia.After tracheotomy and immediately correcting anoxia,all the 21 patients recovered from arrhythmia within 3 days.4 patients died in this group(3.84%).Conclusion:Pneumonectomy,in patients older than 70,results in the parameters of FEV 1,MVV and FVC lower than 50%.Significant anoxia is the cause of arrhythmia.更多还原
