【摘要】 目的 比较瑞芬太尼、丙泊酚、艾司洛尔用于支撑喉镜手术气管插管时患者的心血管反应。 方法 选取2009年1-3月就诊的60例拟于全身麻醉下行择期支撑喉镜下声带息肉切除术的患者，随机分为丙泊酚组、艾司洛尔组和瑞芬太尼组，每组20例。麻醉诱导采用咪达唑仑、芬太尼和丙泊酚，患者意识消失后给予琥珀胆碱。1 min后各组分别给予丙泊酚2 mg/kg、艾司洛尔1 mg/kg和瑞芬太尼1 μg/kg。30 s后进行气管插管。记录患者诱导前及插管前、插管后1、3、5 min的心率和血压水平。 结果 各组插管前的收缩压和心率较诱导前明显降低，插管后1、3 min的收缩压和心率较插管前升高（Plt;0.05)。丙泊酚组和艾司洛尔组插管后的收缩压较瑞芬太尼组升高（Plt;0.05)。丙泊酚组插管后心率较瑞芬太尼组增加（Plt;0.05)。 结论 对行支撑喉镜手术的患者，气管插管前30 s给予1 μg/kg瑞芬太尼较2 mg/kg丙泊酚和1 mg/kg艾司洛尔能更有效地减轻气管插管时的血流动力学反应。【Abstract】 Objective To assess the different effects of remifentanil, propofol, and esmolol on hemodynamic responses during intubation in CO2 laser endolaryngeal microsurgery (CO2-LELM). Methods A total of 60 patients aged from 18 to 65 years, admitted from January to March 2009 and scheduled to undergo elective CO2-LELM under general anesthesia for treatment of vocal cord polyp were randomly assigned to a propofol group, an esmolol group, and a remifentanil group. Anesthesia was induced with midazolam (0.015-0.02 mg/kg), fentanyl (1 μg/kg), and propofol (1 mg/kg). After the patients became unconscious, succinylcholine (1 mg/kg) was given one minute later. Then the patients in the three groups received propofol (2 mg/kg), esmolol (1 mg/kg), and remifentanil (1 μg/kg), respectively. Intubation was performed 30 secconds later. Heart rate (HR) and systolic blood pressure (SBP) were measured noninvasively before general anesthesia induction (baseline, Tb), just before intubation(Ti), and one, three, and five minutes after intubation (T1, T3, T5). Results The demographic data including age, sex and body weight were comparable in the three groups. Tracheal intubation caused significant increases in SBP and HR in all groups compared with Ti (Plt;0.05). After intubation, SBP in the propofol group and the esmolol group were significantly higher than that in remifentanil group (Plt;0.05), and HR in the propofol group was significantly higher than that in the remifentanil group (Plt;0.05). Conclusion In patients with CO2-LELM, remifentanil (1 μg/kg) administrated 30 seconds before intubation is maximal effective compared with propofol (2 mg/kg) or esmolol (1 mg/kg) in attenuating the hemodynamic responses to oraltracheal intubation.

Methods Data was collected from April 2009 to November 2009. Sixty patients after cesarean section under continuous epidural anesthesia were randomly divided into three different groups.Group A was given sufentanil 0.3 μg/mL and 0.125% ropivacaine for PCEA, group B was given sufentanil 0.4 μg/mL and 0.125% ropivacaine, group C was given sufentanil 0.5 μg/mL and 0.125% ropivacaine. The analgesia effects were evaluated by the visual analogue scales (VAS). Side effects were also recorded. Results The VAS scores were significantly the highest in group A than that in group B and group C, the VAS scores in group B were higher than that in group C (Plt;0.05). The incidence of side effects, such as postoperative nausea and vomiting, lethargy, and pruritus, was not significant among the three groups (Pgt;0.05). Conclusion 0.5 μg/ mL sufentanil and 0.125% ropivacaine recommended for PCEA with background 4 mL/h is safe and effective for patients after cesarean section.
【摘要】 目的 比较术后芬太尼皮下镇痛（PCSA）与硬膜外镇痛（PCEA）的临床效果，以及对胃肠功能的影响。 方法 2009年1-6月间观察择期硬膜外麻醉下经腹子宫切除术患者120例，术后分别实施PCSA与PCEA，观察术后第4、8、12、24、48 h的镇痛、镇静情况，呼吸循环、恶心呕吐及其他不良事件，记录术后首次肛门排气时间，测评术后镇痛满意度。 结果 术后两组患者镇痛优良率均在90%以上，各时点镇痛评分、镇静评分、恶心呕吐发生率、首次肛门排气时间以及患者镇痛优良率差异均无统计学意义（Pgt;0.05）。 结论 术后芬太尼PCSA与PCEA一样，效果确切，对术后胃肠功能无明显影响，患者满意，是一种安全、有效的镇痛方法。【Abstract】 Objective To compare clinical efficiency and gastrointestinal reaction of subcutaneous patient-controlled analgesia (PCSA) and epidural patient-controlled analgesia (PCEA) with fentanyl analgesic for patients after operation. Methods A total of 120 patients having undergone transabdominal hysterectomy under epidural anesthesia between January and June 2009 accepted PCSA or PCEA after operation. We evaluated the state of analgesia and sedation at the 4th, 8th, 12th, 24th and 48th hour after operation. We also looked into the respiration, blood circulation, nausea, vomiting and other abnormal events of the patients during the first 48 hours after operation. At the same time, we recorded the first time of anal exsufflation after operation and the degree of patients’ satisfaction. Results The analgesic effective rate was higher than 90% in both groups. There were no significant differences in analgesia and sedation scores at above-mentioned points after operation, incidence of nausea and vomiting, first time of anal exsufflation or analgesic effective rate between the two groups. Conclusion PCSA with fentanyl can be as effective in relieving postoperative pain as PCEA with fentanyl without obvious adverse effect in the gastrointestinal function. Therefore, PCSA is a safe and effective method to alleviate postoperative pain.
目的:探讨甲状腺手术中氟比洛芬酯对丙泊酚—瑞芬太尼麻醉效果的影响。方法:将210例择期丙泊酚—瑞芬太尼麻醉下行甲状腺手术患者随机分为对照组和氟比洛芬酯组,每组105例。于切皮前30 min,对照组静脉注入等量生理盐水10mL,氟比洛芬酯组经静脉注入氟比洛芬酯注射液100 mg。分别记录患者麻醉前10 min (T0)、切皮时(T1)、切皮后10 min (T2)、切除腺体时 (T3)以及拔管时 (T4) 的血流动力学 (SBP、DBP、HR) 的变化以及术后口述描述评分(VRS)。结果:与对照组比较, 氟比洛芬酯组T14时SP、DP均降低,两组差别有统计学意义(Plt;005)。氟比洛芬酯组离开手术室时无痛率明显高于对照组,两组差别有统计学意义(Plt;005)。结论:氟比洛芬酯对丙泊酚—瑞芬太尼麻醉下行甲状腺手术患者血流动力学影响小,且减轻术后疼痛,术后恢复更为舒适。
目的:比较瑞芬太尼联合异丙酚或依托咪酯全麻在腹腔镜妇科手术中的临床效果。方法:择期腹腔镜妇科手术80例,随机分成瑞芬太尼异丙酚组(RP组)和瑞芬太尼依托咪酯组(RE组),各40例。两组全麻诱导用药相同,维持麻醉RP组采用瑞芬太尼联合异丙酚、RE组采用瑞芬太尼联合依托咪酯。记录基础值、诱导后、插管后1 min、3 min、气腹时、气腹后10、20、30、40 min的动脉收缩压(SBP)、舒张压(DBP)、心率(HR);记录停药至自主呼吸恢复、睁眼、拔除气管导管、恢复定向能力的时间;记录清醒即刻及清醒后1、2、4、8、12、16、20、24 h患者疼痛程度,采用VAS评分;记录24 h内不良反应发生情况。 结果: 两组SBP、DBP均在诱导后明显低于基础值(Plt;001), 插管后恢复,气腹开始后趋于平稳;两组HR均在诱导后减慢(Plt;001),插管后及气腹开始时恢复。RP组自主呼吸恢复、呼之能睁眼、拔除气管导管及恢复定向能力的时间均明显短于RE组(Plt;001)。麻醉清醒即刻、清醒后1、2、4、8 h VAS评分RE组明显低于RP组(Plt;005),12、16、20、24 h VAS评分两组比较无显著性差异(Pgt;005)。术后发生恶心呕吐患者数RP组明显减少(Plt;005)。 结论:全麻行腹腔镜妇科手术时,瑞芬太尼联合异丙酚或依托咪酯都能缓解气腹及手术引起的血流动力学变化,瑞芬太尼联合异丙酚术后苏醒快且能明显降低术后恶心呕吐的发生率,但术后疼痛较为严重。
目的 探讨丙泊酚-瑞芬太尼对肝脏缺血再灌注损伤的保护作用以及作用机制。 方法 2009年6月－2011年12月选择择期需阻断肝门的肝脏手术患者40例，随机分为丙泊酚-瑞芬太尼组（P组）和异氟醚组（I组），每组20例。在术前（T0）和肝门阻断开放后30 min（T1）、60 min（T2）、6 h（T3）、24 h（T4）、72 h（T5）分别抽取动脉血，测定天冬氨酸氨基转移酶（AST）、丙氨酸氨基转移酶（ALT）和肿瘤坏死因子α（TNF-α）的含量。 结果 两组AST、ALT、TNF-α较术前均有增高，差异有统计学意义（P＜0.05）；P组增高幅度明显低于I组，差异有统计学意义（P＜0.05）。 结论 丙泊酚-瑞芬太尼对肝脏缺血再灌注损伤具有保护作用，抑制TNF-α的产生可能为其作用机制之一。
