Background: Midazolam is a short-acting benzodiazepine frequently used in the perioperative setting. This study aimed to investigate the potential impact of intraoperative midazolam on postoperative delirium (POD) in older patients undergoing non-cardiac surgery.

Methods: This study included patients aged ≥ 65 years who received general anaesthesia between April 2020 and April 2022 in multiple hospitals across China. POD occurring within 7 days was assessed using the 3-minute Diagnostic Interview for Confusion Assessment Method (3D-CAM). Univariable and multivariable logistic regression models based on the random effects were used to determine the association between midazolam administration and the occurrence of POD, presented as risk ratio (RR) and 95% confidence intervals (CI). Kaplan-Meier cumulative incidence curve was plotted to compare the distribution of time to POD onset between patients who received midazolam and those who did not. Subgroup analyses based on specific populations were performed to explore the relationship between midazolam and POD.

Results: In all, 5,663 patients were included, of whom 723 (12.8%) developed POD. Univariate and multivariable logistic regression analyses based on random effects of different hospitals showed no significant association between midazolam medication and POD among older population (unadjusted RR=0.96, 95% CI: 0.90-1.30, P=0.38; adjusted RR=1.09, 95% CI: 0.91-1.33, P=0.35). Kaplan-Meier curve showed no difference in the distribution of time to POD onset (Hazard ratio [HR]=1.02, 95%CI: 0.88-1.18, P=0.82). The results of subgroup analyses found that intraoperative midazolam treatment was not associated with POD in the specific subgroups of patients.

Conclusions: Intraoperative administration of midazolam may not be associated with an increased risk of POD in older patients undergoing non-cardiac surgery.

背景:咪达唑仑是一种短效苯二氮卓类药物,常用于围术期环境。本研究旨在探讨术中使用咪达唑仑对接受非心脏手术的老年患者术后谵妄(POD)的潜在影响:本研究纳入了 2020 年 4 月至 2022 年 4 月期间在中国多家医院接受全身麻醉的年龄≥ 65 岁的患者。采用 3 分钟意识障碍诊断访谈评估法(3D-CAM)对 7 天内发生的 POD 进行评估。基于随机效应的单变量和多变量Logistic回归模型用于确定咪达唑仑用药与POD发生之间的关系,以风险比(RR)和95%置信区间(CI)表示。绘制了 Kaplan-Meier 累计发病率曲线,以比较接受和未接受咪达唑仑治疗的患者之间 POD 发病时间的分布情况。根据特定人群进行了分组分析,以探讨咪达唑仑与 POD 之间的关系:总共纳入了 5,663 名患者,其中 723 人(12.8%)出现了 POD。基于不同医院随机效应的单变量和多变量逻辑回归分析表明,在老年人群中,咪达唑仑用药与 POD 之间无显著关联(未调整 RR=0.96,95% CI:0.90-1.30,P=0.38;调整 RR=1.09,95% CI:0.91-1.33,P=0.35)。卡普兰-梅耶曲线显示,POD发病时间分布无差异(危险比[HR]=1.02,95%CI:0.88-1.18,P=0.82)。亚组分析结果显示,术中咪达唑仑治疗与特定亚组患者的POD无关:结论:在接受非心脏手术的老年患者中,术中使用咪达唑仑可能与 POD 风险增加无关。

Background: Recent evidence indicates that general anesthesia and sleep-wake behavior share some overlapping neural substrates. GABAergic neurons in the central amygdala (CeA) have a high firing rate during wakefulness and play a role in regulating arousal-related behaviors. The objective of this study is to investigate whether CeA GABAergic neurons participate in the regulation of isoflurane general anesthesia and uncover the underlying neural circuitry.

Methods: Fiber photometry recording was used to determine the changes in calcium signals of CeA GABAergic neurons during isoflurane anesthesia in Vgat-Cre mice. Chemogenetic and optogenetic approaches were used to manipulate the activity of CeA GABAergic neurons, and a righting reflex test was used to determine the induction and emergence from isoflurane anesthesia. Cortical electroencephalogram (EEG) recording was used to assess the changes in EEG spectral power and burst-suppression ratio during 0.8% and 1.4% isoflurane anesthesia, respectively. Both male and female mice were used in this study.

Results: The calcium signals of CeA GABAergic neurons decreased during the induction of isoflurane anesthesia and was restored during the emergence. Chemogenetic activation of CeA GABAergic neurons delayed induction time (mean ± SD, vehicle vs. clozapine-N-oxide: 58.75±5.42 s vs. 67.63±5.01 s; n=8, P=0.0017) and shortened emergence time (385.50±66.26 s vs. 214.60±40.21 s; n=8, P=0.0017) from isoflurane anesthesia. Optogenetic activation of CeA GABAergic neurons produced a similar effect. Furthermore, optogenetic activation decreased EEG delta power (Pre-stim vs. Stim: 46.63%±4.40% vs. 34.16%±6.47%; n=8, P=0.0195) and burst-suppression ratio (83.39%±5.15% vs. 52.60%±12.98%; n=8, P=0.0002). Moreover, optogenetic stimulation of terminals of CeA GABAergic neurons in the basal forebrain (BF) also promoted cortical activation and accelerated behavioral emergence from isoflurane anesthesia.

Conclusions: Our results suggest that CeA GABAergic neurons play a role in general anesthesia regulation, which facilitates behavioral and cortical emergence from isoflurane anesthesia through the GABAergic CeA-BF pathway.

背景:最近的证据表明,全身麻醉和睡眠-觉醒行为有一些重叠的神经基底。中央杏仁核(CeA)中的GABA能神经元在清醒时具有较高的发射率,并在调节唤醒相关行为中发挥作用。本研究旨在探讨杏仁核中央 GABA 能神经元是否参与异氟醚全身麻醉的调控,并揭示其潜在的神经回路:方法:采用纤维光度记录法测定Vgat-Cre小鼠在异氟烷麻醉过程中CeA GABA能神经元钙信号的变化。化学遗传学和光遗传学方法被用来操纵CeA GABA能神经元的活动,右反射试验被用来确定异氟烷麻醉的诱导和唤醒。皮层脑电图(EEG)记录分别用于评估0.8%和1.4%异氟醚麻醉期间EEG频谱功率和猝发抑制比的变化。本研究使用了雄性和雌性小鼠:结果:CeA GABA能神经元的钙信号在异氟醚麻醉诱导过程中减少,并在苏醒过程中恢复。对CeA GABA能神经元的化学激活延迟了异氟烷麻醉的诱导时间(平均值±标度,载体 vs. 氯氮平-氧化物:58.75±5.42 s vs. 67.63±5.01 s;n=8,P=0.0017),缩短了异氟烷麻醉的苏醒时间(385.50±66.26 s vs. 214.60±40.21 s;n=8,P=0.0017)。光遗传激活 CeA GABA 能神经元也产生了类似的效果。此外,光遗传激活降低了脑电图的δ功率(刺激前 vs. 刺激:46.63%±4.40% vs. 34.16%±6.47%;n=8,P=0.0195)和猝发抑制比(83.39%±5.15% vs. 52.60%±12.98%;n=8,P=0.0002)。此外,对基底前脑(BF)中的CeA GABA能神经元末端进行光遗传刺激也促进了大脑皮层的激活,并加速了异氟烷麻醉后的行为唤醒:我们的研究结果表明,CeA GABA能神经元在全身麻醉调节中发挥作用,通过GABA能CeA-BF通路促进行为和大脑皮层从异氟醚麻醉中苏醒。

Background: Diaphragm dysfunction is common in intensive care unit and associated with weaning failure and mortality. Diagnosis gold standard is the transdiaphragmatic or tracheal pressure induced by magnetic phrenic nerve stimulation. However, the equipment is not commonly available and requires specific technical skills. We aimed to evaluate ultrasound guided transcutaneous phrenic nerve stimulation for daily bedside assessment of diaphragm function by targeted electrical phrenic nerve stimulation.

Methods: In this randomized cross-over study we compared a new method of ultrasound guided transcutaneous electrical phrenic nerve stimulation (SONOTEPS method) using a peripheral nerve stimulator, with the magnetic phrenic nerve stimulation. Intensive care unit adult patients under mechanical ventilation with a Richmond-Agitation-Sedation-Scale score of -4 or -5 were included. Each patient received the two methods of stimulation, in a randomized order. The primary outcome was the tracheal pressure (Ptrach) induced by stimulation.

Results: We analyzed 232 measures of Ptrach from 116 patients of whom 77 presented a diaphragm dysfunction (Ptrach < 11 cmH2O) and 50 a severe diaphragm dysfunction (Ptrach < 8 cmH2O). The Passing-Bablok regression showed no significant differences (intercept A of -0.03 [CI95:-0.83-0.52] and slope B of 0.98 [CI95:0.90-1.05]) between SONOTEPS method and magnetic stimulation which were positively correlated (R²=0.639). The mean bias was -1.08 (CI95 5.02, -7.18) cmH2O. The receiver operating curves showed an excellent performance for the diagnosis of diaphragm dysfunction and severe diaphragm dysfunction with respectively an area under curve of 0.90 (CI95 0.83-0.97) and 0.88 (CI95 0.82-0.95). This performance was not significantly affected by the body mass index or the presence of a neck catheter.

Conclusions: The SONOTEPS method is a simple and accurate tool for bedside assessment of diaphragm function with ultrasound guided transcutaneous phrenic nerve stimulation in sedated patients with no or minimal spontaneous respiratory activity.

背景:膈肌功能障碍在重症监护室很常见,与断奶失败和死亡率有关。诊断的金标准是通过磁性膈神经刺激诱发经膈或气管压力。然而,这种设备并不常见,而且需要特定的技术技能。我们旨在评估超声引导下的经皮膈神经刺激,通过有针对性的膈神经电刺激对膈肌功能进行日常床旁评估:在这项随机交叉研究中,我们比较了使用外周神经刺激器的超声引导经皮膈神经电刺激新方法(SONOTEPS 方法)和磁性膈神经刺激方法。研究对象包括接受机械通气的重症监护室成人患者,这些患者的里士满激动-镇静-量表评分为-4 或-5 分。每位患者按随机顺序接受两种刺激方法。主要结果是刺激引起的气管压力(Ptrach):我们分析了 116 名患者的 232 次 Ptrach 测量值,其中 77 人出现横膈膜功能障碍(Ptrach < 11 cmH2O),50 人出现严重横膈膜功能障碍(Ptrach < 8 cmH2O)。Passing-Bablok 回归结果显示,SONOTEPS 方法与磁刺激之间无明显差异(截距 A 为 -0.03 [CI95:-0.83-0.52],斜率 B 为 0.98 [CI95:0.90-1.05]),两者呈正相关(R²=0.639)。平均偏差为-1.08 (CI95 5.02, -7.18) cmH2O。接收器工作曲线显示,横膈膜功能障碍和严重横膈膜功能障碍的诊断效果极佳,曲线下面积分别为 0.90 (CI95 0.83-0.97) 和 0.88 (CI95 0.82-0.95)。体重指数或颈部导管的存在对这一性能没有明显影响:SONOTEPS方法是一种简单而准确的工具,可用于对无自发呼吸活动或自发呼吸活动极少的镇静患者进行超声引导下经皮膈神经刺激的膈肌功能床旁评估。
