Abstract This observational study aimed to compare the glottic view between video and direct laryngoscopy for tracheal intubation in surgical position thyroid surgery with intraoperative neuromonitoring. Patients scheduled elective neuromonitoring were enrolled. After induction of anesthesia, patients positioned posture a standard inclined pillow under their head back. An investigator assessed using percentage opening (POGO) scale modified Cormack–Lehane grade then sequentially while same...

Objectives/Hypothesis To compare effect of 1 and 2 mg/kg sugammadex on the incidence intraoperative bucking neuromonitoring (IONM) quality in thyroid surgery. Study Design Randomized controlled trial. Methods Patients qualified for surgery with IONM were eligible this double‐blind, randomized, After tracheal intubation 0.6 rocuronium, or was administered to patients group I II, respectively.

Ventilation should be assisted without asynchrony or cardiorespiratory instability during anesthesia emergence until sufficient spontaneous ventilation is recovered. In this multicenter cohort study, we develop and validate a reinforcement learning-based Artificial Intelligence model for control Emergence (AIVE) from general anesthesia. Ventilatory hemodynamic parameters 14,306 surgical cases at an academic hospital between 2016 2019 are used training internal testing of the model. The...
For safe nasotracheal intubation without middle turbinate injury, the tracheal tube should pass through lower pathway, which is beneath inferior and immediately above nasal floor of nostril. The purpose this study was to assess influence tip lifting on incidence passing preformed Ring-Adair-Elwyn (RAE) tubes pathway during intubation.Patients were randomly assigned a "nasal group" or "neutral group." patients in group, an investigator pulled cephalad direction when inserting RAE into nostril...
Intraoperative neuromonitoring (IONM) is frequently used in thyroid surgery to reduce recurrent laryngeal nerve injury. The use of neuromuscular blockade agent facilitate tracheal intubation, a common cause IONM failure. We performed retrospective analysis assess the efficacy neostigmine-glycopyrrolate as reversal for during surgery. Rocuronium (0.6 mg/kg) was administered muscle relaxation. Neostigmine (2 mg) and glycopyrrolate (0.4 were immediately after intubation. Cricothyroid...
Retrospective Observational Study
Abstract Tuffier line is a common landmark for spinal anesthesia. The 10th rib has been suggested as new to predict the intervertebral levels. We evaluated accuracy of these 2 anatomic landmarks identifying L4-L5 space using ultrasonography in elderly patients with hip fracture. Seventy-nine scheduled fracture surgery under anesthesia were included. In lateral decubitus position side up, was identified alternately line, drawn between highest points both iliac crests, and line. an imaginary...
BACKGROUND: Maneuvers for preventing passive regurgitation of gastric contents are applied to effectively occlude the esophagus throughout rapid sequence induction and intubation. The aim this randomized, crossover study was investigate effectiveness cricoid paratracheal pressures in occluding through anesthesia videolaryngoscopy. METHODS: After 40 adult patients, location esophageal entrance relative glottis upper trachea at low region were assessed using an ultrasonography, outer diameter...
BACKGROUND: Accurate identification of the cricothyroid membrane is crucial for successful cricothyroidotomy. The aim this study was to compare conventional downward and modified upward laryngeal handshake techniques in terms accuracy identify nonobese female patients. METHODS: In 198 anesthetized patients, identified by either technique (n = 99) or 99). According technique, palpating neck from greater cornu hyoid bone, thyroid laminae, cricoid cartilage. located moving up sternal notch....
Summary The aim of this study was to evaluate the effectiveness cricoid and paralaryngeal force for oesophageal entrance occlusion during induction anaesthesia. Seventy‐four patients were included in randomised, crossover study. relative position glottis outer anteroposterior diameter upper assessed at baseline, after application 30 N force, rate with direct laryngoscopy. changed 45 out 74 anaesthesia laryngoscopy compared awake state. decreased mean ( SD ) a similar degree (8.5 (2.1) mm 6.4...
BACKGROUND: Cricoid pressure has been used as a component of the rapid sequence induction and intubation technique. However, concerns have raised regarding effectiveness safety cricoid pressure. Paratracheal pressure, potential alternative to prevent regurgitation gastric contents or aspiration, studied be more effective in preventing insufflation during positive ventilation. adopt paratracheal compression into our practice, adverse effects including its effect on glottic view direct...
BACKGROUND Different head and neck positions may affect video laryngoscopy in terms of laryngeal exposure, intubation difficulty, advancement the tracheal tube into glottis occurrence palatopharyngeal mucosal injury. OBJECTIVE We investigated effects simple extension, elevation without extension sniffing position on using a McGRATH MAC laryngoscope. DESIGN A randomised, prospective study. SETTING Medical centre governed by university tertiary hospital. PATIENTS total 174 patients undergoing...
The GBAR experiment aims to measure the gravitational acceleration of antihydrogen H.It will use H+ ions formed by interaction antiprotons with a dense positronium cloud, which require about 10 positrons produce one H + .We present first results on positron accumulation, reaching 3.8 ± 0.4 × 8 e collected in 560 s.
Clinicians sometimes encounter resistance in advancing a tracheal tube, which is inserted via nostril, from the nasal cavity into oropharynx during nasotracheal intubation. The purpose of this study was to investigate effect neck extension on advancement tubes intubation.Patients were randomized 'neck group (E group)' or 'neutral position (N for controlled trial. After induction anesthesia, RAE tube nostril. For E group, an anesthesiologist advanced with patient's extended. N without...
Abstract This prospective, randomized controlled trial evaluated the effect of neostigmine for intraoperative neuromonitoring (IONM) during thyroid surgery. Forty subjects undergoing thyroidectomy with IONM, into administration after tracheal intubation (Group N, n = 20) or control treatment normal saline C, 20), completed trial. Electromyography amplitudes vagus nerve (V1) were recorded before dissection. The time from initial V1 signal check to successful stimulation was recorded. In Group...
BACKGROUND For nasotracheal intubation, the nasal pathway between inferior turbinate and hard palate (lower pathway) is preferred for patient safety. However, selecting lower can be challenging because passage of tube through usually performed blindly. OBJECTIVES We investigated whether facing bevel tracheal in cephalad direction could help advancing during intubation. DESIGN A randomised, blinded trial. SETTING SMG-SNU Boramae Medical Center, Seoul National University College Medicine,...
Mounier-Kuhn syndrome (MKS) is a disease characterized by dilation of the trachea and mainstem bronchi.Due to risk airway leakage, pulmonary aspiration, tracheal damage, MKS can be fatal in patients undergoing intubation.Moreover, may not diagnosed preoperatively due its rarity.In this case, patient neurosurgery was incidentally with during general anesthesia.During anesthesia induction, difficulties management led anesthesiologist suspect MKS.Airway leakage resolved case using oropharyngeal...
Intraoperative neuromuscular blockade affects the resting tension between vocal cords. We assessed effect of on postoperative sore throat and hoarseness following tracheal intubation in patients undergoing lumbar spinal surgery prone position. Altogether, 99 were included; 50 did not receive blockade, 49 received moderate during maintenance anesthesia. Neuromuscular was performed depending use intraoperative neurophysiological monitoring. The number attempts, time to achieve intubation,...
Background and Objectives: Retrograde intrarenal surgery (RIRS) is a minimally invasive technique for nephrolithiasis. RIRS performed via monitor screen displaying magnified surgical site. Respiration can affect the stability of view during because kidneys are close to diaphragm. The purpose this trial compare effect anesthesia type on between spinal general anesthesia.
