胸腔镜下肺叶切除术患者围术期多模式镇痛效果及其对免疫功能的影响

 目的 探讨多模式镇痛对胸腔镜下肺叶切除术患者围术期镇痛和免疫功能的影响。方法 胸腔镜下肺叶切除术患者90例,男51例,女39例,年龄18~65岁,随机分为3组(每组30例),对照组:静脉自控镇痛(patient controlled intravenous analgesia,PCIA);超前镇痛组:氟比洛芬酯+PCIA;多模式镇痛组:氟比洛芬酯+胸椎旁神经阻滞(thoracic paravertebral nerve block,TPVB)+PCIA。记录术中丙泊酚、瑞芬太尼用量及舒芬太尼追加量,术后6、24、48 h疼痛视觉模拟评分(visual analogue scale,VAS)、48 h内镇痛泵按压次数,采用流式细胞仪测量麻醉前(T₀)、术毕(T₁)、术后24 h(T₂)、术后72 h(T₃)T淋巴细胞亚群(CD3⁺、CD4⁺、CD8⁺)与NK细胞百分比,并计算CD4⁺/CD8⁺。结果 与对照组比较,超前镇痛组和多模式镇痛组瑞芬太尼用量和舒芬太尼追加量显著减少(P<0.05),超前镇痛组术后6 h的VAS评分明显降低(P<0.05)、T₁时NK细胞百分比以及CD3⁺、CD4⁺、CD4⁺/CD8⁺水平明显升高(P<0.05);多模式镇痛组术后6 h、24 h VAS评分均较低(P<0.05),镇痛泵按压次数少(P<0.05),T₁、T₂时NK细胞百分比、CD3⁺、CD4⁺、CD4⁺/CD8⁺水平及T₃时CD3⁺、CD4⁺较高(P<0.05),术后恶心呕吐发生率低(P<0.05)。结论 胸腔镜肺叶切除术中,多模式镇痛可增强术后镇痛效果,减少围术期阿片类药物使用量,减轻免疫抑制,且不增加术后恶心呕吐发生率。其中,氟比洛芬酯联合椎旁神经阻滞围术期镇痛更完善,对免疫功能影响小。

Effects of multimodal analgesia on perioperative analgesia and immune function in patients undergoing thoracoscopic lobectomy

Objective To investigate the effects of multimodal analgesia on perioperative analgesia and immune function in patients undergoing thoracoscopic lobectomy. Methods Ninety patients with lung resection under thoracoscope (51 males, 39 females, and aged 18 to 65) were randomly and evenly divided into three groups:the control group in which patient-controlled intravenous analgesia(PCIA)was adopted, Preemptive analgesia group that received flurbiprofen axetil +PCIA, and the multimodal analgesia group where flurbiprofen axetil+thoracic paravertebral nerve block (TPVB)+ PCIA was used. The usage of intraoperative propofol, remifentanil dosage and additional dosage of sufentanil were recorded. The VAS scores at postoperative 6, 24, 48 h and the number of times the analgesia pump was pressed within 48 h were calculated. Venous blood samples were collected before anesthesia (T₀), at the end of the surgery(T₁), and on the morning of one day(T₂) and three days (T₃) after operation. The levels of T lymphocyte subsets(CD3⁺ , CD4⁺ and CD8⁺ ) and NK cells were measured by flow cytometry, and the ratio of CD4⁺/CD8⁺ was calculated.Results Compared with control group, the dosage of remifentanil and sufentanil supplementation in preemptive analgesia group and multimodal analgesia group were significantly decreased (P<0.05); In preemptive analgesia group,the VAS score at 6 h after surgery was significantly decreased (P<0.05), the percentage of NK cells at T₁ and the levels of CD3⁺, CD4⁺ and CD4⁺/CD8⁺ were significantly increased (P<0.05); In multimodal analgesia group, the VAS scores at 6 h and 24 h after surgery were significantly decreased (P<0.05), the analgesia pump was pressed less frequently(P<0.05), the percentage of NK cells and the levels of CD3⁺, CD4⁺,CD4⁺/CD8⁺ at T₁ and T₂, and the levels of CD3⁺ and CD4⁺ at T₃ were increased(P<0.05), and the incidence of postoperative nausea and vomiting group was lower (P<0.05).Conclusions For thoracoscopic lobectomy, multimodal analgesia can enhance postoperative analgesia, reduce perioperative opioid dosage, alleviate immunosuppression, and increase no incidence of postoperative nausea and vomiting. Besides, flurbiprofen ester combined with paravertebral nerve block had can contribute more to perioperative analgesia and immune function.
