Dexmedetomidine might be effective in combination with sevoflurane for anesthesia, but prospective randomized controlled clinical trials with which to verify this hypothesis are lacking. In total, 120 patients who underwent embolization of an intracranial aneurysm were recruited from Anhui Provincial Hospital and Renmin Hospital of Wuhan University of China and randomly allocated to two groups. After intraoperative administration of 2% to 3% sevoflurane inhalation, one group of patients received pump-controlled intravenous injection of 1.0 ~tg/kg dexmedetomidine for 15 minutes followed by maintenance with 0.3 ~tg/kg/h until the end of surgery; the other group of patients only underwent pump-controlled infusion of saline. Bispectral index monitoring revealed that dexmedetomidine-assisted anesthesia can shorten the recovery time of spon- taneous breathing, time to eye opening, and time to laryngeal mask removal. Before anesthetic induction and immediately after laryngeal mask airway removal, the glucose and lactate levels were low, the S100~ and neuron-specific enolase levels were low, the perioperative blood pressure and heart rate were stable, and postoperative delirium was minimal. These findings indicate that dexmedetomidine can effectively assist sevoflurane for anesthesia during surgical embolization of intracranial aneurysms, shorten the time to consciousness and extubation, reduce the stress response and energy metabolism, stabilize hemodynamic parameters, and reduce adverse reactions, thereby reducing the damage to the central nervous system.

目的探讨术前给予帕瑞昔布钠对瑞芬太尼快通道麻醉行腹腔镜胆囊切除术后苏醒期的影响。方法择期行腹腔镜胆囊切除术患者64例,随机均分为两组,术前20min分别静注帕瑞昔布钠40mg(P组)或等量生理盐水2ml(C组)。术中持续泵注丙泊酚和瑞芬太...目的探讨术前给予帕瑞昔布钠对瑞芬太尼快通道麻醉行腹腔镜胆囊切除术后苏醒期的影响。方法择期行腹腔镜胆囊切除术患者64例,随机均分为两组,术前20min分别静注帕瑞昔布钠40mg(P组)或等量生理盐水2ml(C组)。术中持续泵注丙泊酚和瑞芬太尼维持麻醉。记录自主呼吸恢复时间、睫毛反射时间、睁眼时间、拔管时间;记录拔管后患者疼痛VAS评分、Ramsay镇静评分和躁动情况。结果两组患者的自主呼吸恢复时间、睫毛反射时间、睁眼时间、拔管时间差异无统计学意义。与C组比较,拔管后10、30、60 min P组疼痛VAS评分、躁动评分明显降低,Ramsay镇静评分明显升高(P<0.05)。结论帕瑞昔布钠能较好地减轻快通道麻醉清醒期的躁动和疼痛,明显改善患者的血流动力学和应激反应,不良反应少,提高患者苏醒期的安全性。展开更多
目的比较两种快通道麻醉方法在肾移植手术的应用效果。方法 36例符合美国麻醉师协会（American Society of Anesthesiologists,ASA）分级Ⅲ~Ⅳ级的终末期肾病拟行肾移植术患者,采用随机数字法将患者随机分为Ⅰ组和Ⅱ组各18例。两组麻醉...目的比较两种快通道麻醉方法在肾移植手术的应用效果。方法 36例符合美国麻醉师协会（American Society of Anesthesiologists,ASA）分级Ⅲ~Ⅳ级的终末期肾病拟行肾移植术患者,采用随机数字法将患者随机分为Ⅰ组和Ⅱ组各18例。两组麻醉诱导用药相同。Ⅰ组吸入0.8%-1.8%七氟醚,使用小剂量顺式阿曲库胺[0.05-0.10 mg/（kg.h）]持续输注和常规剂量瑞芬太尼[0.1-1.0μg/（kg.min）]维持麻醉,预计手术结束前30 min停用顺式阿曲库胺,结束前15 min停止使用七氟醚,并将瑞芬太尼减低至维持量的1/10-1/5用至拔除气管导管。Ⅱ组使用丙泊酚[5-12 mg/（kg.h）]全凭静脉麻醉,以常规剂量顺式阿曲库胺[0.1-0.2 mg/（kg.h）]及瑞芬太尼[0.1-1.0μg/（kg.min）]维持麻醉,预计手术结束前30 min停用顺式阿曲库胺,手术结束后观察两组患者的睫毛反射时间、睁眼时间、拔管时间、术中知晓例数以及苏醒期躁动评分。结果Ⅰ组与Ⅱ组的睫毛反射时间、睁眼时间、拔管时间比较差异无统计学意义（均为P〉0.05）。两组患者均未出现术中知晓。Ⅰ组的躁动发生率明显低于Ⅱ组（P〈0.05）。Ⅰ组的顺式阿曲库胺、瑞芬太尼用量均明显少于Ⅱ组（均为P〈0.05）。结论七氟醚＋瑞芬太尼＋顺式阿曲库铵或丙泊酚＋瑞芬太尼＋顺式阿曲库铵这两种快通道麻醉方法用于肾移植手术均具有可控性良好、安全性高、患者苏醒迅速等特点,而七氟烷＋瑞芬太尼＋顺式阿曲库铵的组合更节省药物用量,且苏醒质量更高。展开更多
