目的

观察右美托咪定联合羟考酮对胃癌根治术患者免疫功能的影响。

方法

选择新疆维吾尔自治区人民医院2015年6月至2016年3月全麻下行胃癌根治术患者60例,用随机数字表法将其分为2组:羟考酮组(O组)和右美托咪定联合羟考酮组(DO组),每组30例。所有患者行静脉全麻,静脉泵注异丙酚4~6 mg·kg-1·h-1,靶控输注瑞芬太尼3~4 μg/L,术毕前30 min静脉注射羟考酮0.04 mg/kg;DO组诱导后以0.5 μg·kg-1·min-1的速度静脉泵注右美托咪定至术毕前30 min。术毕采用经静脉自控镇痛。于术前(T0)、术毕(T1)、术后4 h(T2)和8 h(T3)时抽取静脉血标本,用流式细胞仪测定T淋巴细胞亚群CD3+、CD4+、CD8+和NK细胞CD16+/CD56+水平,计算CD4+/CD8+比值。记录术后镇痛VAS评分、恶心呕吐、呼吸抑制、头痛等不良反应发生情况。

结果

与T0时比较,两组T1、T2时CD3+、CD4+、CD4+/CD8+比值、NK细胞CD16+/CD56+水平降低,CD8+水平升高(P<0.01)。与O组比较,DO组T1、T2时CD3+、CD4+、CD4+/CD8+比值和NK细胞CD16+/CD56+水平升高(P<0.01),不良反应发生率差异无统计学意义。

结论

右美托咪定联合羟考酮对胃癌根治术患者术后免疫功能抑制程度较单纯羟考酮减轻。

Objective

To observe the effect of dexmedetomidine combined with oxycodone in immune function of patients undergoing gastrectomy.

Methods

Sixty patients undergoing elective radical resection of gastric carcinoma were randomized into two groups from People's Hospital of Xinjiang Uygur Autonomous Region between June 2015 to March 2016: Group O treated with oxycodone and Group DO dexmedetomidine combined with oxycodone, with 30 cases in each group. All patients received intravenous general anesthesia with 4-6 mg·kg-1·h-1 propofol and target controlled infusion of 3-4 μg/ml remifentanil. Group O were injected through veins 0.04 mg/kg oxycodone 30 min before the end of surgery, and patients in Group DO were give intravenous injection of 0.5 μg·kg-1·h-1 dexmedetomidine consistently till 30 min before the end of the operation. The patient-controlled intravenous analgesia (PCIA) was used for postoperative analgesia. Before surgery (T0), at the end of surgery (T1), 4 days (T2) and 8 days (T3) after surgery, venous blood samples were collected for detection of T lymphocyte subsets CD3+, CD4+, CD8+ and natural killer (NK) cell CD16+/CD56+ levels by flow cytometry. CD4+/CD8+ ratio was calculated. The occurrence of postoperative VAS score and adverse reactions such as nausea, vomiting, headache and respiratory expression were recorded after surgery.

Results

Compared with the value at T0, the levels of CD3+, CD4+, CD4+/CD8+, and CD16+/CD56+ were significantly decreased at T1 and T2, and the CD8+ level was increased (P<0.01). Compared with group O, the levels of CD3+, CD4+, CD4+/CD8+, and CD16+/CD56+ in group DO were significantly increased at T1 and T2 (P<0.01), and there was no significant difference in the incidence of adverse reactions after surgery in the two groups.

Conclusion

The effect of dexmedetomidine combined with oxycodone is better than oxycodone alone on immune function in patients undergoing radical resection of gastric carcinoma.
