The observation of remifentanil anesthesia in patients undergoing endoscopy sinus surgery Abstract Objective To observe the effects of recovery and the anesthetics’ consumptions during endoscopy sinus surgery with remifentanil anesthesia and isoflurane anesthesia. Methods Forty patients of ASA I-II aged 16-75 undergoing elective endoscopy sinus surgery were randomly divided into 2 groups: remifentanil group (R group)and isoflurane group (I group). Both groups were induced with Fentanyl 2•g/kg, Midazolam 1-3 mg, Atropine 0.5mg, Propofol 2mg/kg, Atracrium 0.5mg/kg intravenously. The patients were mechanically ventilated (Vt 8-10ml/kg, RR 12-14bpm, EtCO2 was maintained at 29-31mmHg in both groups) and inhalated N2O 65%(total gas flow volume 2.5L/min).The patients in R group were maintained with Remifentanil intravenously 0.1-0.3•g•kg-1•min-1 . The patients were inhalated with 1.5-3.5% isoflurane in I group. Hemodynamics changes were monitored at entering the operation room(T0, baseline), after tracheal intubation 5’(T1), at pluging into nasal cavity for topical anesthesia(T2), after pluging 5’(T3), 5 min after the beginning of operation (T4), 30 min(T5), at the end of drug infusion(T6), at extubation(T7), 5 min after extubation(T8). Blood loss, the time of spontaneous respiratory recovery and the time of opening their eyes and extubation, awake scores, the consumption of Isoflurane or Remifentanil during the operation were recorded. Results The recovery time of respiration, the time of opening their eyes and extubation were shorter in R group than in I group. The level of awakeness was much better in R group. The consumption of maintenance anesthesia drugs was lower in R group than in I group. Conclusion General anesthesia with remifentanil intravenously and N2O inhalation can make patients recovery better and quicker than general anesthesia with isoflurane and N2O inhalation, moreover this method dosen’t enhance patients’ consumption. 随着鼻内镜手术的开展,鼻腔手术范围扩大,为了保证病人术中的舒适安全,越来越多的手术采用了全身麻醉。以往我院常用静脉诱导,异氟醚、氧化亚氮和氧气吸入维持。但是术毕停药后,异氟醚短时间内迅速从体内清除导致清醒质量不佳,甚至躁动不安,增加了术后出血、呼吸道阻塞、误吸的可能。术后拔管一般需要半小时左右,减缓了手术台的周转率。 |
一、资料与方法<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 一般资料:择期行鼻内镜手术的病人40例(男性27例,女性13例),年龄16~75岁,体重45~118kg,ASA分级为I-II级。符合下列标准之一者将被排除本临床研究。15d内服用单胺氧化酶抑制药物者;已知有对阿片类药物过敏或高敏史者;心、肺、肝、肾功能不全者;休克者;怀疑入选者不具备配合研究的能力,如语言障碍、伴有其他病史或共存疾病,研究者认为不适宜者;怀疑有嗜酒、滥用药物者;全身感染者。随机分为两组,瑞芬太尼组(R组)和异氟醚组(I组)各20例。试验前获得受试者或其家属签字的知情同意书。 |
2.观察指标 (1)两组入室(T0)、气管插管后5’(T1)、术前填充鼻腔付肾纱条时(T2)、填后5’(T3)、手术开始5’(T4)、30’(T5)、停药时(T6)、拔管时(T7)、拔管后5’(T8)各时段血流动力学(SBP、DBP、HR)变化; 二、结果 1.两组病人一般资料、手术时间及术中出血量比较无显著性差异(P>0.05),见表1。 |
三、讨论<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> 鼻内镜鼻窦手术部位深,术野狭小,操作精细困难,且鼻腔内病变部位血管丰富,易出血。为提高病人术中的舒适性和安全性,近年来我院鼻内镜手术多采用全身麻醉。理想的麻醉状态要求麻醉平稳,镇痛完善,术中出血少,术野清晰,术后苏醒完全,气道保护性反射恢复,避免呼吸道梗阻和误吸。 参考文献 石嵩,1972年出生,1994年取得医学学士学位,并进入北京同仁医院麻醉科工作至今。2003年获得医学硕士学位。1999年晋升为主治医师。 |
