Reliability of Tracheal Temperature as a Measurement of Core Body Temperature During Cardiac Surgery Using Cardiopulmonary Bypass.
J Clin Med
January 2025
Department of Anesthesiology and Pain Medicine, Anam Hospital, Korea University College of Medicine, Seoul 02841, Republic of Korea.
: To compare tracheal temperature (T) with nasopharyngeal temperature (T) in patients undergoing cardiac surgery using cardiopulmonary bypass (CPB). : T was measured using a thermistor in the cuff of an endotracheal tube and T was monitored using an esophageal stethoscope. Depending on the management of the CPB strategy, the operation was divided into four periods (pre-CPB, cooling, rewarming, and post-CPB).

Article Synopsis
- Contralateral tension pneumothorax can be a life-threatening complication during one-lung ventilation, often misdiagnosed due to general anesthesia masking symptoms.
- A case study was presented of a patient with tension pneumothorax during thoracic spine surgery, and no prior cases were found in a comprehensive search of anesthesia databases from 2001 to 2017.
- Delayed diagnosis can lead to serious consequences, as initial signs like rising inspiratory pressure may not be recognized early enough, emphasizing the importance of heightened awareness and improved diagnostic tools like ultrasound and training.
Correlations between heart sound components and hemodynamic variables.

Department of Anesthesiology and Pain Medicine, Asan Medical Center, Brain Korea 21 Project, University of Ulsan College of Medicine, 88, Olympic-ro 43-gil, Songpa-gu, Seoul, 05505, Korea.
Article Synopsis
- * Different drugs were administered to manipulate cardiac contractility and vascular resistance, and the correlation between heart sound changes (specifically S1 amplitude) and blood pressure metrics was analyzed.
- * The findings suggest that changes in S1 amplitude are closely linked to cardiac contractility variations, but not significantly related to vascular resistance changes, indicating the potential for non-invasive monitoring of hemodynamic conditions.
Effectiveness of Cricoid and Paratracheal Pressures in Occluding the Upper Esophagus Through Induction of Anesthesia and Videolaryngoscopy: A Randomized, Crossover Study.

Department of Anesthesiology and Pain Medicine, SMG-SNU Boramae Medical Center, College of Medicine, Seoul National University, Seoul, Republic of Korea.
Background: Maneuvers for preventing passive regurgitation of gastric contents are applied to effectively occlude the esophagus throughout rapid sequence induction and intubation. The aim of this randomized, crossover study was to investigate the effectiveness of cricoid and paratracheal pressures in occluding the esophagus through induction of anesthesia and videolaryngoscopy.
Methods: After the induction of anesthesia in 40 adult patients, the location of the esophageal entrance relative to the glottis and location of the upper esophagus relative to the trachea at the low paratracheal region were assessed using an ultrasonography, and the outer diameter of the esophagus was measured on ultrasound before and during application of cricoid and paratracheal pressures of 30 N.
Bedside ultrasonic localization of the nasogastric tube in a patient with severe COVID-19: A case report.
World J Clin Cases
May 2022
Cancer Center, Daping Hospital, Army Medical University, Chongqing 400042, China.
Background: The indwelling nasogastric tube is commonly used for supplying enteral nutrition to patients who are unable to feed themselves, and accurate positioning is essential in the indwelling nasogastric tube in the body of the aforementioned patients. In clinical practice, abdominal radiography, auscultation, and clinical determination of the pH of the gastric juice are routinely used by medical personnel to determine the position of the tube; however, those treatments have proved limitations in specific cases. There are few case reports on the precise positioning of the nasogastric tube in patients with coronavirus disease 2019 (COVID-19), for whom a supply of necessary nutrition support is significant throughout the process of treatment.
