A novel technique of blindly positioning bronchial blockers for one-lung ventilation: a prospective, randomized, crossover study.
J Cardiothorac Surg
January 2025
Department of Anesthesiology and Pain Medicine, Seoul National University Hospital, Seoul National University College of Medicine, 101 Daehak-ro, Jongno-gu, Seoul, 03080, Republic of Korea.
Background: Several methods for blindly positioning bronchial blockers (BBs) for one-lung ventilation (OLV) have been proposed. However, these methods do not reliably ensure accurate positioning and proper direction. Here, we developed a clinically applicable two-stage maneuver by modifying a previously reported one-stage maneuver for successful insertion of a BB at the appropriate depth and direction in patients requiring lung isolation where a flexible bronchoscope (FOB) is not applicable.

A BIS <35 was considered very low and was not only without evident clinical benefit but also associated with a greater risk of postoperative delirium. We considered the association between BIS and the anesthetic dose of inhalational agents, quantified using the minimum alveolar concentration (MAC) fraction, which was the patient's end-tidal inhalational agent concentration divided by the agent's altitude- and age-adjusted minimum alveolar percentage concentration.

January 2025
Department of Anaesthesiology and Pain Medicine, Samsung Medical Centre, Sungkyukwan University School of Medicine, Seoul, Republic of Korea.
Background: Remimazolam is a novel ultra-short-acting benzodiazepine known for its hemodynamic stability over propofol. However, its hemodynamic effects compared to those of etomidate are not well established. This study aimed to determine whether the use of remimazolam is non-inferior to etomidate with regard to the occurrence of post-induction hypotension in patients undergoing coronary arterial bypass grafting.

Objectives: Suspension laryngoscopy can trigger vagal reflexes, leading to a decrease in heart rate, a phenomenon that is more common in patients with a high body mass index (BMI). This study aims to systematically evaluate the effect of BMI on heart rate during suspension laryngoscopy (SL-HR) in patients with laryngeal lesions.
Methods: We employed univariate generalized linear regression and stratified analyses to assess the relationship between BMI and changes in SLHR, adjusting for confounders such as age, gender, intubation type, and depth.
Qualitative study on the ability of neurological nurses to manage patients with indwelling gastrointestinal canal.
Front Med (Lausanne)
December 2024
The First Affiliated Hospital of China Medical University, Shenyang, China.
Aim And Objectives: This study aims to assess the proficiency of nurses in the neurology department in managing patients with indwelling gastrointestinal canal.
Background: Many critically ill patients in neurology departments require the placement of nasoenteric tubes to provide enteral nutrition. However, in clinical practice, there exists considerable variability in nurses' competencies regarding the management of patients with nasoenteric tubes.
