关于术后镇痛对呼吸功能影响的临床研究

Clinical research on effects of postoperative analgesia of respiratory function

目的观察不同镇痛方式对于术后呼吸功能的影响。方法选择普外科45例患者,随机均分为3组,即实验组:静脉镇痛组(VA组)、硬膜外镇痛组(EA组),对照组:肌注镇痛组(MA组)。分别在术前、术后12 h、24 h进行疼痛视觉模拟评分(VSA评分)和呼吸功能的检测和记录,并对术后并发症进行记录和比较。结果实验组患者的术后疼痛视觉模拟评分、呼吸功能均优于对照组,并且术后相关并发症的发生率显著低于对照组。结论硬膜外和静脉途径镇痛均能有效的缓解术后疼痛,改善术后患者的呼吸功能,减少相关并发症。

Objective To oberserve the effects of analgesia of respiratory function in patients after the operations. Methods 45 patients scheduled operation were divided randomly into 3 groups ： experimental groups,including intravenous-morphine analgesia group（VA group） and epidural-morphine and control group which received morphine through intramuscularly-injection（MA analgesia group（EA group）, group） . In this research,the preoperative and postoperative values were monitored and recorded,such as visual analogue scales （VAS values）, artery blood gas analysis, postoperative complications and etc. Results The values of the experimental group,such as the values of artery blood gas analysis,visual analogue scales （VAS values） were better than those of the control group. However,in the research of the complications,the control group has a higher incidence of the complications. Conclusion This research proved that postoperative analgesia, through the methods of epidural or venous analgesia, may alleviate the post-operation algesia efficiently, better the respiratory function, reduce the incidence of related postoperative complications.
