摘要: 目的:观察右美托咪定(Dexmedetomidine,Dex)对颅内动脉瘤患者围拔管期应激反应和苏醒质量的影响。方法:选择Hunt/ Hess分级为I~II 级的施行颅内动脉瘤夹闭术患者50 例。随机分成右美托咪定(A组)和生理盐水对照组 (B组) ,每组25例。A组麻醉前 10 min 微泵静脉注射右美托咪定 0.5 μg/kg,术中 0.4 μg·kg-1·h-1持续泵注,B组给予等容量的0.9%的氯化钠注射液。两组均采用静吸复合全麻。记录入手术室时(T1)、拔管即刻(T2)、拔管后 5 min(T3)、10 min(T4) 的血压(BP)、心率(HR)变化,抽外周静脉血测定皮质醇(COR)、血糖(GLU)、血乳酸(LAC)浓度, 并记录麻醉恢复时间,苏醒期躁动评分、拔管后 30 min 视觉模拟(VAS)镇痛评分和Ramsay镇静程度评分。结果:B组的MAP、HR、COR、GLU、LAC较A组增高更为明显(P<0.01 或P<0.05);B组苏醒期躁动评分和拔管后 30 min VAS评分高于A组,而Ramsay镇静程度评分低于A组(P<0.05)。结论:右美托咪定有效抑制了围拔管期的应激反应,能提高麻醉苏醒质量,不延迟苏醒时间。

Abstract: AIM: To observe the effect of dexmedetomidine on intracranial aneurysms with stress response and awakening quality on tracheal extubation.METHODS: Select Hunt / Hess grading as I-II-class implementation of intracranial aneurysm surgery patients 50 cases, and randomly divided into dexmedetomidine group (group A) and normal saline group (group B), 25 patients in each. Group A were given dexmedetomidine with 0.5 μg/kg continuous infusion for 10 min before anesthesia, intraoperative 0.4 μg·kg-1·h-1 continuous infusion. Group B were given the same dose of 0.9% sodium chloride injection. Both groups were treated with combined intravenous-inhalation anesthesia. We recorded the changes of blood pressure (BP) and heart rate (HR) at into the operating room (T1),extubation (T2), extubation after 5 min (T3), 10 min (T4),measured the concentration of cortisol (COR), blood glucose (GLU), blood lactate (LAC), and recorded anesthesia recovery time,restlessness rating,visual analogue pain scores (VAS) and Ramsay sedation scores after extubation 30 min.RESULTS: The MBP, HR, COR, GLU, LAC of Group B increased more significantly (P<0.01 or P<0.05) than group A. Group B restlessness score and at VAS score 30 minutes after extubation were higher than those of group A, but Ramsay sedation scores were lower in group A (P<0.05).CONCLUSION: Dexmedetomidine can effectively inhibit the stress response to tracheal extubation period, can improve the quality of recovery from anesthesia, do not delay recovery.
