目的 观察开胸食管癌根治术后不同镇痛方法的镇痛效果以及血糖的变化情况 ,探讨不同镇痛方法对食管癌根治术后应激反应的影响。方法 36例行食管癌根治术患者 ,按术后镇痛方法的不同随机分为病人自控镇痛 (PCA)组和肌肉注射镇痛 (MI)组。比较两组镇痛效果 ,监测围麻醉期病人血糖的变化 ,并进行统计学分析。结果 PCA组镇痛效果优于MI组 ,前者视觉疼痛模拟评分 (VAS)低于后者 (P <0 .0 5 )。PCA组血糖浓度相对恒定 ,并且低于MI组 (P <0 .0 5 )。结论 开胸食管癌根治术后PCA镇痛效果良好 ,能有效地降低疼痛所致的应激反应 ,有助于术后恢复。
Objective To observe the analgesic effects of different analgesic methods after thoracotomy esophageal cancer and the changes of blood glucose, and to explore the effect of different analgesic methods on the stress response after esophagectomy. Methods Thirty - six patients undergoing esophageal cancer radical mastectomy were randomly divided into patient - controlled analgesia (PCA) group and intramuscular injection (MI) group according to the method of postoperative analgesia. The analgesic effects of the two groups were compared to monitor the changes of blood glucose in patients during anesthesia and statistical analysis was made. Results The analgesic effect of PCA group was better than that of MI group. The former had lower visual analogue pain score (VAS) than the latter (P <0.05). The blood glucose level in PCA group was relatively constant and lower than that in MI group (P <0.05). Conclusion PCA analgesia after thoracotactic esophagectomy is effective and can effectively reduce the pain-induced stress response and help postoperative recovery.
