摘　　要：目的研究地佐辛与芬太尼术后静脉自控镇痛（PCIA）对胃肠道肿瘤患者免疫功能的影响。方法将80例肿瘤手术患者按数字表法分为地佐辛组与芬太尼组，每组各40例患者。芬太尼组采用芬太尼0．8mg＋生理盐水稀释到100ml镇痛方案；地佐辛组采用镇痛泵使用前先静脉注射5mg负荷量的地佐辛，然后采用地佐辛20mg＋生理盐水稀释到100ml的镇痛方案．手术前、手术后24小时、48小时、72小时测定患者外周血T淋巴细胞亚群（CD3^＋、CD4＋,CD4＋／CD8＋）。结果两组患者的一般资料无统计学差异．两组术后24小时CD3^＋、CD4＋,CD4＋／CD8^＋均较手术前降低，差异有显著性（P〈0．05），两组术后24小时CD3＋、CD4^＋相比地佐辛组更高，差异有显著性（P〈0．05），48小时后两组均升高，而芬太尼组仍低于手术前水平，地佐辛组则恢复接近正常水平，两组相比地佐辛组高于芬太尼组，差异有显著性（P〈0．05），72小时后两组均恢复至术前水平。结论地佐辛术后静脉自控镇痛对患者免疫功能抑制较轻，术后患者免疫功能恢复较快，对机体的免疫功能有较好的保护作用，值得老年胃肠道肿瘤患者临床广泛推广应用。Objective To investigate the effect of patient controlled intravenous analgesia （PCIA） with de- zocine and fentanyl on the distribution of T-lymphocytes in elderly patients with gastrointestinal cancer. Meth- ods 80 patients with tumor undergoing radical operation were randomly divided into dezocine group and fen- tanyl group, 40 cases in each group. All patients used PCIA. The analgesic regimen of fentanyl group was 0.8 mg fentanyl＋saline diluted to 100 ml, the analgesic regimen of dezocine group was dezocine 20 mg＋saline diluted to 100 ml after intravenous injection of 5 mg load of dezocine. Peripheral blood samples were obtained before opera- tion, 24, 48, 72 hours after operation. T-lymphocyte subsets were measured, and used VAS score to record pa- tients＇ satisfaction. Results The amount of CD3^＋,CD4^＋, CD4^＋/CD8＋ lymphocytes decreased 24 hours after opera- tion in two groups （P〈0.05）, The amount of CD3^＋, CD4＋, CD4^＋/CD8^＋ lymphocytes in dezocine groups were nearly to baseline in 48 hours postoperatively, and significantly higher than those of fentanyl group. The whole T-lym- phocytes recovered in 72 hours postoperatively in two groups. Conclusion Dezocine has less impact on immune function in elderly patients with gastrointestinal cancer.
