Objective: To evaluate the effect of reducing-opioids on postoperative delirium (POD) incidence in elderly patients with gastric cancer surgery. Methods: From July 2016 to September 2021, 130 elderly patients undergoing scheduled gastric cancer surgery in Zhejiang Cancer Hospital were selected and divided into conventional opioid general anesthesia group (group A) and reducing-opioids general anesthesia group (group B) according to random number table. Postoperative analgesic pump formula: group A: 0.2% ropivacaine and 1 μg/ml sufentanil solution; Group B: 0.2% ropivacaine solution. POD assessment was performed once daily between 8 am and 8 pm for 3 days after surgery. The primary outcome measures were POD incidence 3 days after surgery, and the secondary outcome measures included anaesthesia related adverse events 3 days after surgery, such as nausea and vomiting, postoperative fever and fatigue. Results: Among the 130 patients, 7 patients were excluded because they did not comply with the POD test after operation. Finally, 123 elderly patients completed the study. There were 59 cases in group A, aged (73±5) years, including 45 males, and 64 cases in group B, aged (71±6) years, including 56 males. The incidence of total POD 3 days after surgery in group A and B was 30.5% (18/59) and 18.8% (12/64), respectively, with no statistical significance (P>0.05). However, POD incidence at 48 and 72 h after operation in group A [27.1% (16/59) and 16.9% (10/59)] was higher than that in group B [10.9% (8/64) and 4.7% (3/64), both P<0.05]. The incidence of nausea and vomiting in group A was higher than that in group B [15.3% (9/59) vs 1.6% (1/64), P<0.05]. Conclusion: Reducing-opioids consumption have no effect on the incidence of total POD 3 d after gastric cancer surgery in elderly patients, but can reduce the risk of POD 48-72 h after surgery.
目的： 探讨少阿片类药物对老年胃癌手术患者术后谵妄（postoperative delirium，POD）发生率的影响。 方法： 选取2016年7月至2021年9月期间在浙江省肿瘤医院行限期胃癌手术的老年患者130例，按随机数字表法分为常规阿片全身麻醉组（A组）和少阿片全身麻醉组（B组）。术后镇痛泵配方为：A组：0.2%罗哌卡因+1 μg/ml舒芬太尼溶液；B组：0.2%罗哌卡因溶液。术后3 d内每天上午8点和晚上8点之间行1次POD评估。主要观察指标是术后3 d的POD发生率，次要观察指标包括术后3 d的麻醉相关不良事件，如恶心呕吐、术后发热和乏力等。 结果： 130例患者中，术后有7例不配合完成POD测试而排除，最终123例老年患者完成研究。A组59例，年龄（73±5）岁，其中男45例。B组64例，年龄（71±6）岁，其中男56例。A、B两组患者术后3 d总POD发生率分别为30.5%（18/59）、18.8%（12/64），差异无统计学意义（P>0.05），但是A组术后48、72 h的POD发生率［27.1%（16/59）、16.9%（10/59）］均高于B组［10.9%（8/64）、4.7%（3/64），均P<0.05］。术后3 d并发症中，A组恶心呕吐发生率高于B组［15.3%（9/59）比1.6%（1/64），P<0.05］。 结论： 少阿片类药物对老年胃癌手术患者术后3 d总POD的发生率无影响，但是可以降低术后48~72 h的POD风险。.
