摘要:
目的 探究并分析右美托咪定不同给药方式联合腹横肌平面阻滞(transversus abdominis plane,TAP)对老年结直肠癌根治术患者术后苏醒以及免疫功能的影响。 方法 选取2018年6月—2019年6月杭州市富阳区第一人民医院收治的95例老年结直肠癌根治术患者,按照随机数字表法将其分为观察组(48例)和对照组(47例)。观察组患者右美托咪定在TAP阻滞中给予,对照组患者麻醉诱导前静脉给予负荷量。观察2组患者一般资料、手术前后血流动力学参数(HR、MAP、SpO2)、苏醒期间SAS评分(Riker镇静和躁动评分)、苏醒期恢复情况、术后疼痛评分、免疫指标(CD4+、CD8+、CD4+/CD8+)。 结果 拔管时2组患者HR及MAP显著高于手术结束时(均P < 0.05);观察组患者睁眼时、拔管时、拔管后30 min躁动评分明显低于对照组(均P < 0.05);观察组患者自主呼吸恢复时间、睁眼时间以及拔管时间均明显短于对照组(均P < 0.05);术后1、3 d 2组患者VAS评分较术后6 h明显降低,观察组患者术后1、3 d VAS评分显著低于对照组(均P < 0.05);观察组术后CD4+、CD8+、CD4+/CD8+水平显著高于对照组,差异有统计学意义(均P < 0.05)。 结论 右美托咪定局部用药联合TAP阻滞相对于静脉用药联合TAP阻滞更能有效缩短患者苏醒时间,改善患者术后免疫功能,值得临床推广。 Abstract:Objective To investigate and analyze the effect of different administration methods of dexmedetomidine combined with transverse abdominal plane (TAP) block on the recovery and immune function of elderly patients after radical resection of colorectal cancer. Methods Total 95 elderly patients with colorectal cancer undergoing radical surgery admitted to the First People's Hospital of Fuyang District from June 2018 to June 2019 were divided into observation group (48 cases) and control group (47 cases) according to the random number table method. The patients in the observation group were given dexmedetomidine in TAP block, and the patients in the control group were given intravenous load before anesthesia induction. The general data, hemodynamic parameters (HR, MAP, SpO2), SAS score (Riker sedation and agitation score), recovery during recovery, postoperative pain score, and immune index (CD4+, CD8+, CD4+/CD8+) were observed. Results The HR and MAP of the two groups at extubation were significantly higher than those at the end of operation (all P < 0.05). The restlessness scores at eye opening, extubation and 30 min after extubation in the observation group were significantly lower than those in the control group (all P < 0.05). The recovery time of spontaneous breathing, eye opening time and extubation time in the observation group were significantly lower than those in the control group (all P < 0.05). The VAS scores of the two groups on the 1st and 3rd day after operation were 6. The VAS score of the observation group were significantly lower than that of the control group at 1 d and 3 d after operation (all P < 0.05). The levels of CD4+, CD8+, CD4+/CD8+ in the observation group were significantly higher than those in the control group (all P < 0.05). Conclusion Dexmedetomidine combined with TAP block is more effective than intravenous drug combined with TAP block in shortening the recovery time and improving the postoperative immune function of patients, which is worthy of clinical promotion. -
