摘要： 目的 观察右旋美托咪定在轻中度颅脑损伤患者术后镇静中的临床效果。方法 选择符合纳入标准的180例轻中度颅脑损伤患者作为研究对象,采用随机数字表法将其分为右旋美托咪定组（A组）、丙泊酚组（B组）和咪唑安定组（C组）。观察并记录患者术后用药前（T1）,用药后1 h（T2）、6 h（T3）、12 h（T4）、12 h（T5）、24 h（T6）的Richmond躁动-镇静（Richmond Agitation and Sedation Scale, RASS）评分、颅内压（intracranial pressure,ICP）值、脑灌注压的变化情况及低血压、心动过缓的发生情况。结果 A组、B组和C组在T1~T3的RASS评分和CPOT评分无显著差异（P>0.05）。A组和B组在T4~T6的RASS得分和CPOT得分显著低于C组（P>0.05）。T4~T6时A组和B组的最佳镇静比例（RASS评分在-2~+1）显著高于C组（P>0.05）。同一时间点B组的过度镇静比例（RASS评分<-2）高于A组（P>0.05）。C组在同一时间点的激动比例（RASS评分>+1）高于A组和B组（P>0.05）。A组和B组在T3~T5时的ICP值显著低于C组（P>0.05）,且A组和C组在所有时间点的lCP值均无差异。三组在所有时间点的CPP（P=0.06）和低血压和心动过缓的发生率（P=0.015）均无差异。结论 右旋美托咪啶在轻中度颅脑损伤患者术后中的镇静疗效安全可靠,更易于使镇静程度控制在理想范围内（RASS评分处于-2~+1分）。

Abstract: Objective To explore the sedative effect of dexmedetomidine on patients with mild to moderate traumatic brain injury after operation and on intracranial pressure （ICP）. Methods A total of 180 patients with mild to moderate traumatic brain injury meeting designed inclusion criteria were enrolled as study subjects, and were divided into group A （dexmedetomidine）, group B （dexmedetomidine + propofol）, and group C （midazolam） by the random number table method. The Richmond Agitation Sedation Scale （RASS） score, ICP, changes of cerebral perfusion pressure （CPP）, and occurrence of hypotension and bradycardia were recorded before surgery （T1）, 1 h （T2）, 2 h （T3）, 6 h （T4）, 12 h （T5）, and 24 h （T6） after surgery. Results The RASS scores and Critical-care Pain Observation Tool （CPOT） scores of group A, group B, and group C at T1-T3 were not significantly different （P>0.05）. The RASS score and CPOT scores of group A and group B at T4-T6 were significantly lower than those of group C （P>0.05）. The proportions of optimal sedation （RASS score at -2 to +1） of group A and group B at T4-T6 were significantly higher than that of group C （P>0.05）, the proportions of over sedation （RASS score < -2） of group B at the same time points were higher than those of group A （P>0.05）, and the proportions of agitation （RASS score > +1） of group C at the same time points were higher than those of group A and group B （P>0.05）. The ICP values of group A and group B at T3-T5 were significantly lower than the values of group C （P>0.05）, and no difference in the lCP values were found between group A and group B at all time points. There was no difference in CPP at all time points （P=0.06） and the incidence rates of hypotension and bradycardia （P=0.15） among the three groups. Conclusion Dexmedetomidine produces a safe and reliable sedative effect on patients with mild to moderate traumatic brain injury after operation, and tends to achieve optimal sedation （RASS score at -2 to +1）.
