摘要
目的比较体外循环与非体外循环冠状动脉搭桥术对患者呼吸功能的影响。方法择期行冠脉搭桥术的患者20例,分为体外循环组(CCABG)和非体外循环组(OPCABG),测定气管插管拔除后48 h内FVC与FEV1指标的变化,并测定2组手术前后不同时点桡动脉血氧含量(Ca(O2))和术后氧合指数(OI)。结果术后24 h 2组患者FVC和FEV1均较术前显著下降(P均<0.05),组间比较有显著性差异(P<0.05)。2组患者术后各时点Ca(O2),均较术前显著下降(P均<0.05),OI均较术前显著提高(P<0.01),术后各时点OPCABG组Ca(O2)显著高于CCABG组(P<0.01),术后各时点QIOPCABG组均显著低于CCABG组(P<0.01)。结论冠状动脉搭桥术对患者的肺功能有显著影响,但OPCABG对患者的呼吸功能影响较小,且呼吸功能的恢复明显优于CCABG。
Objective It is to compare the effect of the patient＇s respiratory function between onrpump and off-pump coronary artery bypass grafting. Method 20 patients had been done operation of coronary artery bypass grafting according the plan, They were divided into two groups： on-pump（CCABG） and off-pump（OPCABG）. The changes of the FVC and FEV1 were assayed after extubation within 48 h. And the Ca（O2 ） of the radial artery and the oxygenation index（OI） were assayed in correspond time point before and after operation. Results After operation within 24 h, the FVC and the FEV1 of two groups were more decrease obviously than before（ P 〈 0.05 ）, and the respiratory function of the OPCABG group and the CCABG group had significant deviation （P〈0.05）. The Ca（02） of the two groups were decrease obviously（P〈0. 05）, and the OI were increase obviously than before（P〈 0.01）, In the all time point after operation, the Ca（O2） of the OPCABG group were higher obviously than the CCABG group（ P 〈 0.01 ）, but the OI of the OPCABG group were lower obviously than the CCABG group（ P〈 0.01 ）. Conclusion The coronary artery bypass grafting have conspicuous effect on the lung function of patients, but the OPCABG have less effect on respiratory function of patients and more benefit to the recovery than the CCABG.
