目的 探讨超声引导双侧眶下神经阻滞对鼻中隔偏曲矫正术患者术后镇痛效果、麻醉苏醒质量的影响。方法 回顾性选取2021年8月至2025年8月我院收治的行鼻中隔偏曲矫正术治疗的患者120例，按麻醉方案不同，分为全麻组和眶下神经阻滞组，各60例。全麻组进行气管插管全身麻醉和术后镇痛泵镇痛，眶下神经阻滞组在全麻基础上进行超声引导双侧眶下神经阻滞+术后镇痛泵镇痛。比较两组麻醉前、拔管即刻、拔管后5 min血流动力学（心率、平均动脉压）水平、术后麻醉苏醒质量（苏醒时间、苏醒期躁动发生情况）、术后24 h按压镇痛泵次数、术后3 h、6 h、12 h、24 h镇痛效果[数字分级评分（NRS）]及麻醉前、拔管后5 min时血清应激指标水平及不良反应发生情况。结果 拔管即刻、拔管后5 min，眶下神经阻滞组平均动脉压、心率均低于全麻组（P＜0.05）；眶下神经阻滞组躁动发生率、术后24 h按压镇痛泵次数低于全麻组（P＜0.05）；术后3 h、6 h、12 h，眶下神经阻滞组NRS评分均低于全麻组（P＜0.05）；拔管后5 min，眶下神经阻滞组血清皮质醇（Cor）、去甲肾上腺素（NE）水平低于全麻组（P＜0.05）；两组麻醉相关不良反应总发生率比较，差异无统计学意义（P＞0.05）。结论 超声引导双侧眶下神经阻滞可有效减轻患者鼻中隔矫正术后循环波动、术后疼痛及应激反应，减少麻醉药物用量，降低躁动发生率。

目的 观察布托啡诺联合舒芬太尼镇痛方案在重症监护病房（ICU）机械通气患者中的效果及对血流动力学的影响。方法 采用前瞻性、随机对照研究,选取2021年3月—2023年3月商丘市第三人民医院ICU收治的118例机械通气患者,按1∶1随机分为观察组、对照组各59例。观察组采取布托啡诺联合舒芬太尼镇痛方案,对照组采取舒芬太尼镇痛方案。比较两组镇静、镇痛情况（镇静起效时间、停药后苏醒时间、机械通气时间、ICU住院时间、丙泊酚总用量）。以用药前（T0）、用药后6 h（T1）、12 h（T2）、24 h（T3）为时间节点,比较两组血流动力学指标[心率（HR）、平均动脉压（MAP）]。以用药后6 h（t1）、12 h（t2）、18 h（t3）、24 h（t4）为时间节点,比较两组Ricker镇静-躁动评分（SAS）、重症监护疼痛观察工具（CPOT）评分。比较两组不良反应发生情况。结果 用药后观察组镇静起效、停药后苏醒、机械通气、ICU住院时间均短于对照组,丙泊酚总用量少于对照组（P<0.05）;t1~t4时观察组CPOT评分均低于对照组,SAS评分均高于对照组（P<0.05）;T1、T2、T3时观察组HR、MAP波动幅度小于对照组（P<0.05）;观察组不良反应总发生率为10.17%,与对照组15.25%相比,差异无统计学意义（P>0.05）。结论 布托啡诺、舒芬太尼联合治疗ICU机械通气患者,可有效增强镇静、镇痛效果,维持血流动力学稳定,且安全性较高,有利于促进患者病情转归。

Objective To observe the effect of butorphanol and sufentanil combined analgesia regimen in patients with mechanical ventilation in intensive care unit（ICU）and its influence on hemodynamics．Methods A prospective,randomized controlled study was carried out on 118 patients with mechanical ventilation in ICU from March 2021 to March 2023,and the enrolled patients were randomly divided into observation group and control group with 59 cases in each group．The observation group received butorphanol combined with sufentanil analgesia regimen,and the control group received sufentanil analgesia regimen．The conditions of sedation and analgesia（sedation onset time,recovery time after drug withdrawal,mechanical ventilation time,ICU stay length,total dosage of propofol）were compared between the two groups．The hemodynamic indexes [heart rate（HR）and mean arterial pressure（MAP）] of the two groups were compared before medication（T0）,6 h（T1）,12 h（T2）and 24 h（T3）after medication as time nodes．At 6 h（t1）,12 h（t2）,18 h（t3）,24 h（t4）after medication,Ricker Sedation-Agitation Scale（SAS）and Critical Care Pain Observation Tool（CPOT）score were compared between the two groups．The occurrence of adverse reactions was compared between the two groups．Results The onset of sedation,recovery after drug withdrawal,mechanical ventilation and ICU stay in the observation group were shorter than those in the control group,and the total dosage of propofol was lower than that in the control group（P<0.05）．At t1 to t4,CPOT score of observation group was lower than that of control group,and SAS score was higher than that of control group（P<0.05）．The fluctuation amplitude of HR and MAP in the observation group was smaller than that in the control group at T1,T2 and T3（P<0.05）．The total incidence of adverse reactions in the observation group was 10.17%,compared with 15.25% in the control group,the difference was not statistically significant（P>0.05）．Conclusions The combination of butorphanol and sufentanil in the treatment of patients with mechanical ventilation in ICU can effectively enhance sedation and analgesia,maintain hemodynamic stability,and have high safety,which is conducive to promote the outcome of the disease．
