Therefore, we evaluated the accuracy of ultrasound-measured skin-to-hyoid bone distance (SHD) for predicting DMV in such population.Methods: This prospective observational study included adult patients with obesity scheduled for elective surgery. Preoperative airway assessment included the modified Mallampati test, thyromental distance, sternomental distance, upper lip bite test, mouth opening, neck mobility, STOP-Bang score, and the SHD measured by a handheld ultrasound probe. The mask ventilation grade was evaluated using the 4-level Han score, and grades 3 and 4 were considered as DMV. The primary outcome was the ability of SHD to predict DMV using area under the receiver operating characteristic curve (AUC) analysis. A multivariate model including the STOP-Bang score, modified Mallampati test, upper lip bite test, and SHD was also assessed.Results: Data from 326 patients were analyzed. The DMV incidence was 22/326 (6.7%). Patients with DMV were predominantly male and had higher weight, STOP-Bang score, modified Mallampati grade, upper lip bite class, and SHD than did those with easy mask ventilation. The AUC (95% confidence interval) of the SHD for predicting DMV was 0.88 (0.84-0.92). An SHD > 1.9 cm had a negative-predictive value of 99%. Multivariate analysis revealed that the SHD was an independent predictor of DMV.Conclusions: In patients with obesity, SHD measured by a handheld ultrasound probe is an independent predictor of DMV and can accurately predict DMV. An SHD ≤ 1.9 cm can exclude DMV with 99% accuracy.","PeriodicalId":17855,"journal":{"name":"Korean Journal of Anesthesiology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144497462","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}

The block group received RIP and SAP blocks (20 ml 0.25% bupivacaine each), whereas the control group received no block. The primary outcome was forced expiratory volume in one second (FEV₁) 2 h postoperatively. Secondary outcomes included forced vital capacity (FVC), FEV₁/FVC ratio, peak expiratory flow (PEF), forced expiratory flow at 25% to 75% (FEF₂₅₋₇₅), pain scores, and opioid requirements.Results: The block and control groups had similar FEV1 values (1.80 ± 0.51 vs. 1.74 ± 0.49; P = 0.659) and FEV1/FVC ratios at 2 h. The block group had higher FVC values at 6 h (2.21 ± 0.76 vs. 1.87 ± 0.48; P = 0.034) and 24 h (2.35 ± 0.65 vs. 1.97 ± 0.53; P = 0.014) and higher PEF and FEF25-75 values at 24 h. Pain scores were lower in the block group at all time points, and opioid consumption was higher in the control group during the first 6 h. The incidence of postoperative nausea and vomiting was similar.Conclusions: This study failed to demonstrate a significant difference in FEV1 values; however, improvements in FVC, PEF, and FEF25-75 indicated a potential positive impact on respiratory function, and combining the RIP and SAP blocks after MRM led to lower pain scores and decreased opioid consumption.","PeriodicalId":17855,"journal":{"name":"Korean Journal of Anesthesiology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-06-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144497463","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}

Its cardiovascular adverse effects include QTc prolongation, hypotension, bradycardia, atrioventricular block, atrial fibrillation, and asystole. Additionally, rocuronium has cardiac side effects, such as bradycardia, hypotension, cardiac arrest, circulatory collapse, and ventricular fibrillation. Herein, we investigated the effects of sugammadex, rocuronium, and combined rocuronium + sugammadex on cardiac electrophysiological parameters.Methods: In vitro experiments were performed using ventricular myocytes obtained from male Wistar rats. Myocyte contraction and relaxation responses were recorded along with action potential (AP), and L-type calcium (ICaL) and potassium channel currents (Ito, Iss, and IK1).Results: Sugammadex caused dose-dependent decreases in myocyte contraction and relaxation responses. Rocuronium had no effect in this respect, whereas its co-administration with sugammadex led to decreased contraction responses. Sugammadex prolonged the AP repolarization phase, whereas rocuronium prolonged all AP phases. Co-administration of sugammadex and rocuronium did not significantly affect AP parameters. Sugammadex suppressed the peak ICaL value, while rocuronium caused an even greater decrease. Co-administration of these drugs further decreased the current-voltage characteristics of the ICaL. However, no significant effects were observed on the potassium currents.Conclusions: Separate or combined administration of sugammadex and rocuronium had various effects on myocyte contractility, AP, and ICaL, which could cause significant changes leading to adverse cardiac events. Further experimental and clinical studies are required to understand the clinical consequences of the modulatory effects of these drugs on cardiac electrophysiological parameters.","PeriodicalId":17855,"journal":{"name":"Korean Journal of Anesthesiology","volume":" ","pages":""},"PeriodicalIF":4.2,"publicationDate":"2025-06-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144333380","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}

Primary endpoints were the burden of illness (BOI) scores and epidural contrast spread. Secondary endpoints included number of needle insertion attempts, sensory blockade, hemodynamic changes, procedure time, radiation dose, adverse events, rescue analgesics, PHN incidence and EuroQoL 5-Dimension scores.Results: Thirty-five injections were performed in 27 patients. Median levels of cephalad-caudad epidural contrast spread were 3, 4, and 5 ml following injections of 2, 3, and 4 ml. Dorsal epidural spread was observed at levels 3, 4, and 5, whereas concurrent ventral spread was observed at levels 2, 3, and 4. BOI scores at 30-180 days significantly decreased (mean difference: -25.3, 95% CI [-57.4 to 6.6], P = 0.005), accounting for reduced rescue analgesic requirements and PHN occurrence and improved EuroQoL 5-Dimension scores. Median sensory blockade at 5 min post-procedure was at level 2, 3, and 4 after 2, 3, and 4 ml of therapeutic injectate. No significant hemodynamic changes were noted at 15 min post-injection. No serious adverse events were observed.Conclusions: Spread of thoracic epidural contrast to all involved nerves was confirmed using this novel technique. Simplified needle placement reduced the technical difficulty and risk of complications. It might be a promising alternative approach for ZAP.","PeriodicalId":17855,"journal":{"name":"Korean Journal of Anesthesiology","volume":" ","pages":"236-247"},"PeriodicalIF":4.2,"publicationDate":"2025-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12142491/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143382715","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We report a case of successful removal using jet ventilation with an injection-time-controllable manual jet ventilator.Cases: A 3.3 cm-long intratracheal mass was located 5 cm below the vocal cords and obstructing 70%-80% of the trachea. Following induction, a rigid telescope under suspension laryngoscopy was used to guide the careful insertion of a hard and long catheter (inner diameter: 1.8 mm; outer diameter: 3 mm; length: 50 cm) beyond the tumor, enabling jet ventilation. The soft, lobulated mass was gradually excised using long forceps under endoscopic visualization. Anesthesia was maintained using total intravenous anesthesia. The operation lasted for 1 h and 45 min.Conclusions: This device ensured oxygenation and ventilation during the endoscopic removal of a large intratracheal tumor.
