Feasibility and accuracy of pediatric core temperature measurement using an esophageal probe inserted through the gastric lumen of a second-generation supraglottic airway device: a prospective observational study.

Background: Accurate core temperature measurement in children is crucial; however, measuring esophageal temperature (TE) using a supraglottic airway device (SAD) can be challenging. Second-generation SADs, which have a gastric channel, can measure TE, and reduce gastric air volume. This study aimed to compare TE, measured using a probe inserted through the SAD gastric channel, with tympanic membrane (TTM) and forehead (TZHF) temperatures, measured using a zero-heat-flux cutaneous thermometer, with rectal temperature (TR).

Update of Vocal Fold Shortening With Retrodisplacement of Anterior Commissure for Voice Feminization.

Objectives: To assess the efficacy and long-term durability of the enhanced technique of Type II Vocal Fold Shortening and Retrodisplacement of the Anterior Commissure (VFSRAC) for voice feminization compared with the preceding Type I method.

Methods: A retrospective analysis encompassed 506 patients drawn from a cohort of 1025 MtF transgender women who underwent VFSRAC between 2003 and 2021. The study period included cases from 2015 to 2021, during which the Type II update technique was implemented, involving a modification to the suture technique.

Comparison of analgesic effect of pericapsular nerve group block and supra-inguinal fascia iliaca compartment block on dynamic pain in patients with hip fractures: a randomized controlled trial.

Background: Patients with hip fracture often experience severe pain, particularly during movement or slight positional change, prior to the occurrence of surgery. It is essential to explore the appropriate analgesic methods before surgery in patients with hip fracture, especially those capable of alleviating dynamic pain. Pericapsular nerve group (PENG) block was introduced as a useful technique for hip analgesia.

Minimizing optical attribute errors for a lane departure warning system using an ultra-wide-angle camera.

Advanced driver assistance systems (ADAS) rely on lane departure warning (LDW) technology to enhance safety while driving. However, the current LDW method is limited to cameras with standard angles of view, such as mono cameras and black boxes. In recent times, more cameras with ultra-wide-angle lenses are being used to save money and improve accuracy.

Effect of Remimazolam- versus Propofol-Based Total Intravenous General Anesthesia on Intraoperative Hemodynamic Stability for Major Spine Surgery in the Prone Position: A Randomized Controlled Trial.

: Remimazolam offers advantages over propofol in terms of hemodynamic stability. However, it remains unclear whether remimazolam-based total intravenous anesthesia (TIVA) can reduce intraoperative hypotension compared to propofol-based TIVA, especially after prone positioning. In this study, we compared the effects of remimazolam- and propofol-based TIVA on intraoperative hemodynamic stability in patients undergoing surgery in the prone position.

Comparison of preemptive and preventive intravenous acetaminophen on opioid consumption in pediatrics undergoing posterior spinal fusion surgery: a randomized controlled trial.

Background: Posterior spinal fusion (PSF), commonly used for adolescent idiopathic scoliosis (AIS), causes severe postoperative pain. Intravenous (IV) administration of acetaminophen has shown promise for opioid-sparing analgesia; however, its analgesic effect and optimal timing for its standard use remain unclear. Our study aimed to evaluate the analgesic effect and optimal timing of IV acetaminophen administration in pediatric and adolescent patients undergoing PSF and requiring adequate pain control.

Effective remimazolam loading dose for adequate sedation in regional anesthesia.

Purpose: Remimazolam is a novel ultrashort-acting sedative considered appropriate for continuous infusion during surgical procedures. Nevertheless, information regarding its loading dose for sedation during surgery is limited. We aimed to determine the 90% effective dose (ED) of the remimazolam loading dose for sedation in patients undergoing limb surgery under regional anesthesia.

The impact of inappropriate steroid exposure before the diagnosis of Kawasaki disease.

Background: Kawasaki disease (KD) is a systemic inflammatory disease characterized by vasculitis. In South Korea, some pediatric doctors empirically prescribe steroids to control febrile pediatric patients. This study aimed to evaluate the clinical characteristics of patients with KD after steroid exposure.

Central Catheter-Induced Cardiac Tamponade in Neonates: Two Case Reports.

Intraoperative central venous catheter (CVC) insertion has become a routine procedure for pediatric cardiac surgery patients at our center. The case in which large amounts of pericardial effusion resulting in cardiac tamponade other than direct puncture of the catheter is a rare, but often causes fatal complications. Two of our patients suffered cardiac collapse after surgery owing to cardiac tamponade.

Postoperative Valgus Deformity and Progression of Ostheoarthritis in Non-Displaced Femoral Neck Fractures.

Purpose: Nondisplaced femoral neck fractures have traditionally been treated with in situ fixation. However, poor surgical and clinical outcomes have been reported for fractures with valgus deformity >15°, and the reduction of valgus impaction has recently been emphasized. In addition, early degenerative osteoarthritis can be caused by cam-type femoroacetabular impingement after healing of femoral neck fractures.

A comparison of the continuous supraclavicular brachial plexus block using the proximal longitudinal oblique approach and the interscalene brachial plexus block for arthroscopic shoulder surgery: A randomised, controlled, double-blind trial.

Background: Continuous interscalene brachial plexus block (ISB) is widely used for arthroscopic shoulder surgery, but the incidence of hemidiaphragmatic paresis (HDP) has been reported to reach 100%. Several methods, including injections distal to the C5-C6 nerve roots, have been attempted to reduce the HDP incidence. However, catheter placement distal to the C5-C6 nerve roots interferes with the surgical site.

Effect of Operating Conditions on the Gasification of Pet-Coke Water Slurry in an Entrained-Flow Gasifier Simulation.

Petroleum coke, commonly known as pet-coke, represents a promising and cost-effective alternative fuel source, produced as a byproduct of large-scale heavy crude oil refining. This study first simulated the gasification process of pet-coke slurry using a three-dimensional computational fluid dynamics (CFD) approach based on the Eulerian-Lagrangian method. The simulation was carried out in a 2-ton-per-day (2TPD) entrained-flow gasifier, aiming to optimize the production of hydrogen (H) and carbon monoxide (CO) as synthetic gases.

Comparison of international medical costs for interventional pain treatment: a focus on Korea and Japan.

Background: The rise in national health care costs has emerged as a global problem given the ever-aging population and rapid development of medical technology. The utilization of interventional pain management has, similarly, shown a continued rise worldwide. This study evaluates the differences in the medical costs in the field of interventional pain treatment (IPT) between two countries: Korea and Japan.

Norepinephrine prevents hypotension in older patients under spinal anesthesia with intravenous propofol sedation: a randomized controlled trial.

Reducing hypotension is crucial as hypotension is the most common side effect of spinal anesthesia, and in older patients with various comorbidities, it can lead to fatality. We hypothesized that continuous infusion of norepinephrine could effectively prevent hypotension in older patients undergoing hip surgery under spinal anesthesia with propofol sedation. The study randomly assigned patients aged ≥ 70 years to either a control (Group C, n = 35) or a norepinephrine group (Group N, n = 35).

Right lower lung midline herniation as a rare complication in an infant with heart-lung transplantation: A case report.

Background: Lung herniation is a rare complication of heart-lung transplantation that can be fatal owing to vascular compromise and airway obstruction. To date, only five cases of lung herniation related to heart-lung transplantation have been reported in the literature; however, to the best of our knowledge, this is the first worldwide report of heart-lung transplantation-related lung herniation in an infant.

Methods: We describe the case of lung herniation as a rare heart-lung transplantation-related complication in an infant.
