摘要
目的:研究不同镇痛方式对老年患者开胸术后肺功能恢复的影响。方法:ASA～级老年患者40例随机分为静脉镇痛组及硬膜外镇痛组。检测术前、术后24h、48h、72h时FVC、FEV(1.0)、MMF及PaO2、PaCO2、D(A-a)O2。结果:与术前相比,两组患者术后FVC、FEV(1.0)、MMF及PaO2均下降(P<0.05),而D(A-a)O2均上升(P<0.05),但硬膜外镇痛组优于静脉镇痛组(P<0.05)。结论:连续硬膜外镇痛可明显改善术后肺功能,促进肺内氧合,是一种较好的术后镇痛方法。
Objective： To explore the effect of different analgesia methods on the recovery of pulmonary function of old patients after operation by open chest approach. Methods： 40 old patients with ASA grade 1-2 were randomly divided into intravenous analgesia group and epidural analgesia group. The change of forced vital capacity （FVC）, forced expiratory volume in 1 secon （FEV1. 0）, maximum midexpiratory flow （MMF）, alveolar oxygen partial pressure（PaO2）, alveolar partial pressure of carbon dioxide （PaCO2） and alveolar arterial oxygen partial pressure gradient （P （A-a）O2） before operation and 23.h, 48h, 72h after operation were recorded respectively. Results ： FVC, FEV （1.0）, MMF and PaO2 all decreased, while P （A-a） O2 increased compared with pre-operation （P〈0. 05）. And epidural analgesia group were better than intravenous analgesia group. Conclusion： Continuous epidural analgesia could improve pulmonary function after operation and promote oxygenation in lung, so it is a good postoperative analgesia method.
