Objective To investigate the efficacy and safety of paracervical block combined with alfentanil in hysteroscopic day surgery under total intravenous anesthesia. Methods This study used a prospective randomized controlled study approach. A total of 60 day surgery patients requiring hysteroscopic surgery under general anesthesia admitted to Weifang People’s Hospital between October and December 2020 were randomly selected. All patients were divided into trial group and control group by completely random number table method, with 30 patients in each group. The trial group received paracervical block combined with total intravenous anesthesia with alfentanil, and the control group received total intravenous anesthesia with alfentanil. The general condition, operation time, recovery time, intraoperative propofol dosage, postoperative pain score, intraoperative motion response and postoperative nausea and vomiting incidence were compared between the two groups. Results There was no significant difference in age, body mass index and incidence of comorbidities between the two groups (P>0.05). There was no significant difference in the operation time, recovery time, pain score at 2 hours after operation, and incidence of nausea and vomiting between the two groups (P>0.05). In the control group, the dose of propofol [(34.07±12.67) vs. (28.33±9.10) mL], the pain score on awakening (1.50±0.78 vs. 0.77±0.50), and the incidence of body movement response (20.0 % vs. 0.0%) were higher than the trial group (P<0.05). Conclusion The use of paracervical block combined with alfentanil in hysteroscopic day surgery under total intravenous anesthesia can reduce the amount of propofol during the operation, reduce postoperative pain, and reduce perioperative adverse reactions, which has a good efficacy and safety.
目的:观察等效剂量瑞芬太尼和芬太尼诱导气管插管对小儿血流动力学的影响。方法:40例择期行全麻患儿随机分为瑞芬太尼组和芬太尼组,麻醉诱导使用咪唑安定0.15mg/kg、丙泊酚2.5mg/kg、芬太尼2.5μg/kg或瑞芬太尼2μg/kg和维库溴铵0.1mg/kg。分别于麻醉诱导前(T0)、诱导后2min(T1)、插管后1、2min(T2、T3)记录心率、收缩压和舒张压。结果:两组诱导前血流动力学指标相似。与T0时比较,两组患儿T1时收缩压、舒张压均降低(Plt;0.05或Plt;0.01),心率均减慢(Plt;0.05或Plt;0.01);瑞芬太尼组T2.T3时收缩压、舒张压降低(Plt;0.05或Plt;0.01),心率减慢(Plt;0.05);芬太尼组T2、T3时收缩压、舒张压升高(Plt;0.05),心率增快(Plt;0.05)。与芬太尼组比较,瑞芬太尼组T1、T2和T3时收缩压、舒张压均降低(Plt;0.05),心率减慢(Plt;0.05)。结论:瑞芬太尼比等效剂量芬太尼能更好地抑制小儿全麻诱导气管插管时的心血管反应。
目的:观察静脉应用小剂量氯胺酮超前镇痛法对接受腹腔镜下子宫切除手术患者术后疼痛及认知功能的影响。方法:38例择期接受腹腔镜下子宫切除术患者(ASA分级12)随机分为氯胺酮组和对照组。氯胺酮组于手术开始前5min静脉滴注氯胺酮015mg·kg-1,术中持续泵注3μg·kg-1·min-1至手术结束;对照组使用生理盐水。记录术中使用氯胺酮后心率,平均动脉压的变化;术后24h内静脉使用芬太尼的剂量,VAS疼痛评分,头晕、恶心、呕吐等不良反应,中枢神经系统症状以及术后2h患者认知功能。结果:两组患者在24h内静脉使用芬太尼的剂量,VAS疼痛评分,不良反应,中枢神经系统症状以及术后2h的认知功能方面没有统计学差异。〖HTH〗结论:〖HTSS〗静脉使用小剂量氯胺酮超前镇痛并不能减少术后芬太尼的用量,不能降低术后疼痛评分。尽管使用小剂量氯胺酮并没有增加患者术后的不良反应,也不影响患者术后认知功能障碍,不建议作为腹腔镜下子宫切除术患者常规使用。
ObjectiveTo evaluate the feasibility and efficiency of patient-controlled analgesia and sedation (PCAS) with propofol and remifentanil for colonoscopy in elderly patients. MethodsSixty elderly patients preparing for painless colonoscopy between May and September 2015 were randomly allocated into PCAS group and total intravenous anesthesia (TIVA) group with 30 patients in each. In the PCAS group, the mixture of remifentanil and propofol at 0.6 mL/(kg·h) was pumped continuously after an initial bolus of 0.05 mL/kg mixture. The examination began three minutes after the infusion was finished. Patients could press the self-control button. Each bolus delivered 1 mL and the lockout time was 1 minute. In the TIVA group, patients received fentanyl at 1 μg/kg and midazolam at 0.02 mg/kg intravenously, and accepted intravenous propofol at 0.8-1.0 mg/kg two minutes later. The examination began when the patients lost consciousness. ResultsA significant decline of mean arterial blood pressure was detected within each group after anesthesia (P < 0.05). The decrease of mean blood pressure in the TIVA group was more significant than that in the PCAS group (P < 0.05). The heart rate, pulse oxygen saturation and respiratory rate decreased significantly after anesthesia in both the two groups (P < 0.05), while end-tidal CO2 increased after anesthesia without any significant difference between the two groups (P > 0.05). The induction time, time to insert the colonoscope to ileocecus, and total examination time were not significantly different between the two groups (P > 0.05). As for the time from the end of examination to OAA/S score of 5 and to Aldrete score of 9, the PCAS group was significantly shorter than the TIVA group (P < 0.05). ConclusionPCAS with remifentanil and propofol can provide sufficient analgesia, better hemodynamic stability, lighter sedation, and faster recovery compared with TIVA.

ObjectiveTo systematically evaluate the effectiveness and safety of dezocine versus fentanyl for postoperative patient-controlled intravenous analgesia (PCIA). MethodsWe electronically searched the specialized trials registered in The Cochrane Library (Issue 2, 2013), the Cochrane anesthesia group, MEDLINE, EMbase, CBM, CNKI, VIP and WanFang Data from inception to February, 2013. Randomized controlled trials (RCTs) on dezocine versus Fentanyl for postoperative PCIA were included. RevMan 5.0 software was used for meta-analysis after critically literature screening, data extracting and assessing of methodological quality independently by two reviewers. ResultsA total of 15 RCTs involving 1 116 patients were finally included. The results of meta-analysis showed that there was no significant difference in postoperative analgesia and sedation at the hour-points of 2 h, 4 h, 6 h, 8 h, 12 h, 24 h, and 48 h after surgery. As for safety, the incidences of postoperative nausea, vomiting, skin pruritus, respiratory depression and uroschesis in the dezocine group were lower than those in the fentanyl group. ConclusionCompared with fentanyl, dezocine has the same effects of analgesia and sedation for PCIA; its incidence of adverse reactions is lower, so dezocine is safer in clinic.

【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.
目的 通过对腹部手术后自控静脉镇痛（PCIA）不同药物配方的研究，探讨酒石酸布托啡诺与舒芬太尼用于术后PCIA临床效果。 方法 将2012年2月－8月收治的60例麻醉分级为Ⅰ～Ⅲ级需术后镇痛的腹部手术患者（均无心、肺、肝、肾、脑、内分泌疾病及过敏史）随机分成两组：酒石酸布托啡诺组（N组，n=30），舒芬太尼组（S组，n=30）。观察镇痛效果和不良反应发生率。 结果 两组镇痛效果差异无统计学意义（P＞0.05），不良反应（包括恶心、呕吐、头晕、嗜睡、皮肤瘙痒、呼吸抑制、尿潴留等），N组发生率均低于S组（P＜0.05）。 结论 酒石酸布托啡诺用于PCIA安全、有效，不良反应少。
