Background: Epinephrine (EPI) or norepinephrine (NOR) is widely used to treat cardiovascular collapse during lipid emulsion (LE) resuscitation for drug toxicity. However, the effect of LE on the vasoconstriction caused by EPI or NOR remains unknown. The purpose of this study was to examine the effect of an LE (Intralipid) on the vasoconstriction caused by EPI and NOR in isolated rat aorta.
Methods: The effect of LE on the vasoconstriction caused by EPI or NOR in isolated rat aorta was examined. Additionally, the effect of LE on the calcium increase caused by EPI or NOR was investigated. The distribution constant (KD: lipid to aqueous phase) of EPI or NOR between a LE (1%) and an aqueous phase was determined.
Results: LE (1 and 2%) did not significantly alter vasoconstriction caused by EPI or NOR in isolated endothelium-intact aorta. Moreover, the LE did not significantly alter the increased calcium level caused by EPI or NOR. The log KD of EPI in the LE (1%) was -0.71, -0.99, and -1.00 at 20, 50, and 100 mM ionic strength, respectively. The log KD of NOR in the LE (1%) was -1.22, -1.25, and -0.96 at 20, 50, and 100 mM ionic strength, respectively.
Conclusions: Taken together, the Intralipid emulsion did not alter vasoconstriction induced by EPI or NOR that seems to be due to the hydrophilicity of EPI or NOR, leading to sustained hemodynamic support produced by EPI or NOR used during LE resuscitation.
背景:肾上腺素(EPI)或去甲肾上腺素(NOR)被广泛用于治疗药物中毒的脂质乳剂(LE)复苏过程中的心血管衰竭。然而,LE 对 EPI 或 NOR 引起的血管收缩的影响仍然未知。本研究的目的是探讨一种脂质乳剂(Intralipid)对EPI和NOR在离体大鼠主动脉中引起的血管收缩的影响:方法:研究了LE对EPI或NOR引起的离体大鼠主动脉血管收缩的影响。此外,还研究了 LE 对 EPI 或 NOR 引起的钙增加的影响。测定了 EPI 或 NOR 在 LE(1%)和水相之间的分布常数(KD:脂相到水相):结果:LE(1% 和 2%)没有明显改变 EPI 或 NOR 在离体内皮接触主动脉中引起的血管收缩。此外,LE 对 EPI 或 NOR 引起的钙水平升高也无明显改变。在 20、50 和 100 mM 离子强度下,LE(1%)中 EPI 的对数 KD 分别为-0.71、-0.99 和-1.00。在 20、50 和 100 mM 离子强度下,LE(1%)中 NOR 的对数 KD 分别为-1.22、-1.25 和 -0.96:综上所述,Intralipid乳液不会改变EPI或NOR诱导的血管收缩,这似乎是由于EPI或NOR的亲水性所致,从而导致在LE复苏过程中使用EPI或NOR产生持续的血流动力学支持。

Background: Minimalist transcatheter aortic valve replacement (TAVR) under monitored anesthesia care (MAC) emphasizes early recovery. Remimazolam is a novel benzodiazepine with a short recovery time. This study hypothesized that remimazolam is non-inferior to dexmedetomidine in terms of recovery after TAVR.
Methods: In this retrospective observational study, remimazolam was compared to dexmedetomidine in patients who underwent TAVR under MAC at a tertiary academic hospital between July 2020 and July 2022. The primary outcome was timely recovery after TAVR, defined as discharge from the intensive care unit within the first day following the procedure. Propensity score matching was used to compare timely recovery between remimazolam and dexmedetomidine, applying a non-inferiority margin of -10%.
Results: The study included 464 patients, of whom 218 received remimazolam and 246 received dexmedetomidine. After propensity score matching, 164 patients in each group were included in the analysis. Regarding timely recovery after TAVR, remimazolam was non-inferior to dexmedetomidine (152 of 164 [92.7%] in the remimazolam group versus 153 of 164 [93.3%] in the dexmedetomidine group, risk difference [95% CI]: -0.6% [-6.7%, 5.5%]). The use of remimazolam was associated with fewer postoperative vasopressors/inotropes (21 of 164 [12.8%] vs. 39 of 164 [23.8%]) and temporary pacemakers (TPMs) (76 of 164 [46.3%] vs. 108 of 164 [65.9%]) compared to dexmedetomidine.
Conclusions: In patients undergoing TAVR under MAC, remimazolam was non-inferior to dexmedetomidine in terms of timely recovery. Remimazolam may be associated with better postoperative recovery profiles, including a lesser need for vasopressors/inotropes and TPMs.
背景:在监测麻醉护理(MAC)下进行经导管主动脉瓣置换术(TAVR)强调早期恢复。雷马唑仑是一种新型苯二氮卓类药物,恢复时间短。本研究假设,就TAVR术后恢复而言,雷马唑仑不劣于右美托咪定:在这项回顾性观察研究中,对 2020 年 7 月至 2022 年 7 月期间在一家三级学术医院接受 MAC 下 TAVR 的患者进行了雷马唑仑与右美托咪定的比较。主要研究结果是 TAVR 术后的及时康复,即术后第一天内从重症监护室出院。采用倾向得分匹配法比较雷马唑仑和右美托咪定的及时恢复情况,非劣效性差值为-10%:研究共纳入 464 名患者,其中 218 人接受了雷马唑仑治疗,246 人接受了右美托咪定治疗。经过倾向评分匹配后,每组各有164名患者纳入分析。在TAVR术后及时恢复方面,雷马唑仑的效果不劣于右美托咪定(雷马唑仑组164例中有152例[92.7%],右美托咪定组164例中有153例[93.3%],风险差异[95% CI]:-0.6% [-6.7% to 5.5%])。与右美托咪定相比,使用瑞马唑仑可减少术后使用血管加压剂/肌注(164例中的21例[12.8%]对164例中的39例[23.8%])和临时起搏器(TPM)(164例中的76例[46.3%]对164例中的108例[65.9%]):结论:对于在 MAC 下接受 TAVR 的患者,就及时恢复而言,雷马唑仑不优于右美托咪定。雷马唑仑可能与更好的术后恢复情况有关,包括对血管抑制剂/肌注和TPM的需求较少。

Background: The ramped position facilitates mask ventilation and endotracheal intubation in patients with obesity. This study aimed to determine whether the ramped position improves supraglottic airway (SGA) insertion in patients with obesity.
Methods: In this prospective, randomized, single-center trial, 48 obese patients undergoing elective surgery were randomized into either ramped or sniffing position groups. The Ambu® AuraGainTM (Ambu A/S), a second-generation SGA, was used. The primary outcome was the time required for the AuraGain insertion. Secondary outcomes included ease and number of insertion attempts, oropharyngeal leak pressure (OLP), and complications. The number needed to treat (NNT) was calculated to ensure ease of insertion.
Results: The time required for the AuraGain insertion was significantly shorter in the ramped group than in the sniffing group (13.0 [11.0, 16.0] vs. 24.0 [21.0, 28.0], P < 0.001). The insertion was easier in the ramped group than in the sniffing group (23/24 vs. 13/24, NNT = 2.4 [95% CI, 1.6, 5.0], P = 0.003). The first-attempt success rate was higher in the ramped group than in the sniffing group, although the difference was not statistically significant (22/24 vs. 18/24, P = 0.319). The OLP and postoperative complication rates were not significantly different between the groups.
Conclusions: The ramped position reduced the time required for the AuraGain insertion in obese patients while providing comparable airway sealing without increasing adverse events. Therefore, a ramped position may be a more suitable option for SGA insertion in this population.

Background: The Rapid-O2 oxygen insufflation device® (Rapid-O2) was designed primarily for rescue oxygenation in cannot intubate, cannot oxygenate (CICO) events; thus, hypercapnia is inevitable. Rapid-O2 was modified to enhance ventilation using the Venturi effect during expiration.
Methods: To determine the most effective combination of inner catheters (20 G, 18 G, 16 G, 14 G, and 2-mm inner diameter [ID] transtracheal catheter [TTC]) and insufflation catheters (16 G, 14 G, and 2-mm ID TTC) for achieving optimum ventilation, insufflating and expiratory flows were measured at an oxygen flow rate of 15 L/min. The insufflating and expiratory pressures were measured at 6-15 L/min. The flows and pressures were measured using a gas flow analyzer. The insufflating and expiratory times were measured using a trachea-lung model to obtain minute volumes. To assess the improvement by modifying the Rapid-O2, minute volumes were measured using the Rapid-O2.
Results: The most appropriate inner catheter was 18 G. The insufflating pressures ranged from 97 (2-mm ID TTC) to 377 cmH2O (16 G) at 15 L/min. During expiration, similar negative pressures of 50 cmH2O were measured in the insufflation catheters at 15 L/min. At lung compliance of 100 ml/cmH2O, the minute volumes through a 2-mm ID and 14 G insufflation catheters were 7.0 and 5.37 L/min, respectively, at 15 L/min. The minute volumes were significantly greater in modified Rapid-O2.
Conclusions: Modified Rapid-O2 provided sufficient minute volumes in adults using a 14 G or 2-mm ID insufflation catheter at 15 L/min, demonstrating its potential for ventilation in CICO events.

Background: Central venous catheterization by anesthesiologists carries risks such as accidental arterial puncture. This case report highlights a rare subclavian artery aneurysm (SAA) detected during ultrasound-guided internal jugular vein (IJV) access, emphasizing the importance of recognizing anatomical variations.
Case: An 88-year-old female with hypertension and atrial fibrillation was scheduled for lumbar laminectomy and posterior fusion. Preoperative evaluation revealed right lower lobe atelectasis and mild aortic sclerosis. During ultrasonography for right IJV catheterization, two vessels of different diameters were observed on the common carotid artery's (CCA's) lateral side. The larger vessel disappeared at the upper neck level, showing arterial pulsation on Color Doppler. Postoperative neck computed tomography confirmed a right SAA and a 5-mm saccular aneurysm in the left intracranial artery. The patient had no vascular disease, trauma, or relevant family histories.
Conclusions: Anesthesiologists should be aware of anatomical variations during IJV catheterization. Ultrasound with Doppler is crucial for accurate artery identification.

Background: In this study, we aimed to investigate whether opioid-sparing anesthesia (OSA) reduces postoperative nausea and vomiting (PONV) in patients undergoing laparoscopic gynecological surgery.
Methods: Adult patients undergoing elective laparoscopic gynecological surgery were randomly assigned to either the opioid-using anesthesia (OUA) or the OSA groups. In the OUA group, remifentanil was administered as an opioid during general anesthesia. In the OSA group, apart from a single dose of 5 μg/kg of alfentanil for tracheal intubation, no other opioids were used. In both groups, a multimodal intravenous non-opioid analgesic regimen was used preferentially in the post-anesthesia care unit (PACU). The primary outcome was the incidence of PONV, assessed by symptoms until the postoperative day (POD) 1.
Results: A total of 120 patients were included in this study. The incidence of nausea in the PACU was significantly lower in the OSA group compared to in the OUA group (31.7% in the OSA group vs. 51.7% in the OUA group, P = 0.026). Pain scores and the incidence of opioid analgesic administration were lower in the OSA group during PACU stay, resulting in a significantly lower number of patients requiring rescue opioid analgesics (3.3% vs. 18.3%, P = 0.008). There were no significant differences in intraoperative vital signs, hemodynamic interventions, or duration of PACU and hospital stay between the two groups.
Conclusions: OSA significantly reduced postoperative nausea, pain scores, and the need for rescue analgesics in the PACU without increasing hemodynamic instability in patients undergoing laparoscopic gynecological surgery.

The primary outcome was the incidence of PONV, assessed by symptoms until the postoperative day (POD) 1.</p><p><strong>Results: </strong>A total of 120 patients were included in this study. The incidence of nausea in the PACU was significantly lower in the OSA group compared to in the OUA group (31.7% in the OSA group vs. 51.7% in the OUA group, P = 0.026). Pain scores and the incidence of opioid analgesic administration were lower in the OSA group during PACU stay, resulting in a significantly lower number of patients requiring rescue opioid analgesics (3.3% vs. 18.3%, P = 0.008). There were no significant differences in intraoperative vital signs, hemodynamic interventions, or duration of PACU and hospital stay between the two groups.</p><p><strong>Conclusions: </strong>OSA significantly reduced postoperative nausea, pain scores, and the need for rescue analgesics in the PACU without increasing hemodynamic instability in patients undergoing laparoscopic gynecological surgery.</p>","PeriodicalId":17855,"journal":{"name":"Korean Journal of Anesthesiology","volume":null,"pages":null},"PeriodicalIF":4.2,"publicationDate":"2024-08-23","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142055928","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Background: The incidence of epistaxis during nasotracheal intubation via the left nostril is more frequent than that during intubation via the right nostril. This study evaluated the effect of the reverse bevel and tip direction of the nasotracheal tube on the incidence of epistaxis during nasotracheal intubation via the left nostril.
Methods: Patients undergoing right-sided maxillofacial surgery requiring left nasotracheal intubation were randomly allocated to the control (tracheal tube in the conventional direction) or reverse (a 180˚ reverse direction, with the tube bevel facing the nasal septum and the leading edge (i.e., the tip) of the bevel pointing away from the nasal septum) groups (n = 37 for both). The primary outcome was the incidence of epistaxis evaluated using videolaryngoscopy.
Results: The incidence of epistaxis in the reverse group was significantly lower than that in the control group (9 [24.3%] vs. 20 [54.1%], P = 0.009; relative risk = 0.45; 95% CI: 0.24, 0.85; absolute risk reduction = 29.8%; number needed to treat = 3.36). The severity of epistaxis was significantly lower in the reverse group (P = 0.002). The first attempt nasal passage (P = 0.027) was significantly higher in the reverse group. Postoperative nasal pain was lower (P < 0.001), and patient satisfaction was higher (P < 0.001) in the reverse group. Nasotracheal tube-related complications did not occur in either group.
Conclusions: The reverse bevel and tip direction of the nasotracheal tube reduced the incidence and severity of epistaxis and increased patient satisfaction among patients undergoing left nasotracheal intubation.
