目的 探讨右美托眯定镇静治疗对重症患者全身炎性反应的影响.方法 将2013年1月至2014年2月江苏省苏州市吴江区第一人民医院60例接受机械通气治疗的重症监护病房(ICU)住院患者按照随机数字表法分为观察组和对照组,各30例.同期选取健康成人志愿者20人为健康对照组.2组患者均在常规治疗基础上给予镇静治疗,必要时给予瑞芬太尼镇痛治疗.观察组给予右美托咪定负荷剂量1 μg/kg,后以0.20 ~0.75μg/(kg·h)维持;对照组给予咪达唑仑负荷剂量0.1 mg/kg,后以0.05~0.20 mg/(kg·h)维持.比较2组患者治疗前和治疗24、48 h的全身炎症反应综合征(SIRS)评分,并在这3个时点抽取静脉血测定血浆C反应蛋白(CRP)、肿瘤坏死因子α(TNF-α)和白细胞介素6(IL-6)的浓度.比较2组患者机械通气时间、ICU住院时间、多器官功能障碍综合征(MODS)发生率和28 d病死率.结果 治疗前,对照组与观察组患者TNF-α、IL-6和CRP浓度均明显高于健康对照组[(25.9±12.1)、(26.5 ±12.3) ng/L比(3.6±1.9) ng/L, (200.3±135.O)、(202.6±139.3) ng/L比(3.0±1.9) ng/L,(126.4±51.9)、(138.4 ±51.8) mg/L比(3.8±2.5)mg/L],差异均有统计学意义(均P<0.05).观察组治疗48 h SIRS评分、TNF-α、IL-6、CRP水平均明显低于对照组[(1.3±0.5)分比(2.4±0.6)分、(12.3±6.8) ng/L比(23.2±11.2) ng/L、(53.0±33.1)ng/L比(168.2±113.8) ng/L、(29.2±11.4) mg/L比(95.5±42.3) mg/L],差异均有统计学意义(均P<0.05).观察组患者机械通气时间、ICU住院时间、MODS发生率均明显低于对照组[(4.9±2.6)d比(8.0 ±2.3)d、(8±3)d比(12±3)d、6.7% (2/30)比30.0% (9/30)],差异均有统计学意义(均P<0.05).结论 右美托咪定镇静治疗能有效降低重症患者血浆炎症因子水平,减轻全身炎性反应,并改善预后。
Objective To investigate the effect of dexmedetomidine on systemic inflammatory response in critically ill patients.Methods Sixty critical patients receiving ventilation in intensive care unit (ICU) were randomly divided into observation group (30 cases) and control group (30 cases);20 healthy adult volunteers were selected as healthy group.The critical patients received sedation therapy on the basis of conventional treatment and analgesia therapy with remifentanil was given if necessary;observation group was additionally administrated with dexmedetomidine [loading dose 1 μg/kg, then maintained with 0.20-0.75 μg/(kg · h)];control group was additionally administrated with midazolam [loading dose 1 mg/kg, then maintained with 0.05-0.20 mg/(kg · h)].The systemic inflammatory response syndrome (SIRS) scores, the levels of serum C reactive protein (CRP), tumor necrosis factor (TNF)-α and interleukin (IL)-6 before treatment, 24 and 48 h after treatment were compared between observation and control group;the duration of mechanical ventilation, length of stay in ICU, incidence of multiple organ dysfunction syndrome (MODS) and 28 day mortality were compared between observation and control group.Results Before treatment, the levels of serum TNF-α, IL-6 and CRP in control group and observation group were significantly higher than those in healthy group [(25.9 ± 12.1), (26.5 ±12.3) ng/L vs (3.6±1.9) ng/L, (200.3±135.0), (202.6±139.3) ng/L vs (3.0±1.9)ng/L, (126.4±51.9), (138.4 ± 51.8) mg/L vs (3.8 ± 2.5) mg/L] (P 〈 0.05).Forty eight hours after treatment, the SIRS scores and the levels of serum TNF-α, IL-6 and CRP in observation group were significantly lower than those in control group [(1.3±0.5) scores vs (2.4±0.6) scores, (12.3±6.8) ng/L vs (23.2±11.2) ng/L,(53.0±33.1) ng/Lvs (168.2±113.8) ng/L, (29.2±11.4) mg/Lvs (95.5 ±42.3) mg/L] (P〈0.05).The duration of mechanical ventilation, length of stay in ICU, incidence of MODS in observation group were significantly lower than those in control group [(4.9 ± 2.6) d vs (8.0 ± 2.3) d, (8 ± 3) d vs (12 ± 3) d, 6.7% (2/30) vs 30.0% (9/30)] (P 〈 0.05).Conclusion Dexmedetomidine infusion during sedation may effectively decrease the levels of serum cytokines, prevent the inflammatory effects and improve the prognosis in critically ill patients.
