Objectives: The current study was designed to assess the clinical predictors of hypoxemia and to develop a multivariable, predictive model for hypoxemia during routine gastrointestinal endoscopy.
Methods: In total, 308 patients were enrolled in the analysis. Demographic data, concurrent chronic disease information, anesthetic dose and Modified Observer's Assessment of Alertness/Sedation (MOAA/S) scores were collected and analyzed statistically.
Results: Multivariate logistic regression indicated that age (OR: 1.04; 95%CI 1.01-1.08), body mass index (BMI) (OR: 1.12; 95%CI: 1.02-1.21) and habitual snoring (OR: 3.71; 95%CI: 1.62-8.48) were independently associated with hypoxemia. A logistic regression function (LR model) was developed to predict hypoxemia considering the parameters of -7.73+0.04 age (years), +0.11 BMI, and +1.31 habitual snoring (yes or no). The area under the receiver operating characteristic (ROC) curve for the LR model was 0.76.
Conclusions: The LR model, consisting of age, BMI and habitual snoring, was a useful predictor of hypoxemia during routine sedation for gastrointestinal endoscopy.

Clinical management and nursing care for patients with tracheostomy following traumatic brain injury.

Tracheostomy is a routine surgical procedure in patients with severe traumatic brain injury, which requires mechanical ventilation to maintain gas exchange and avoid hypoxemia. Inadequate tracheostomy timing, nursing care, and decannulation would lead to a series of complications, such as aggravated pneumonia and prolonged intubation. The effects of early tracheostomy versus late tracheostomy have been explored.

Toluene sulfonic acid remimazolam is a novel benzodiazepine that differs from traditional benzodiazepines (BZDs) due to its rapid onset, swift metabolism, and lack of hepatic or renal metabolism, as well as its reduced effects on cardiac and cerebral functions. Despite its potential advantages, clinical experience with this agent remains limited. This study investigated the effect of remizolam on postoperative delirium in elderly patients undergoing painless bronchoscopy.

Understanding the tumor hypoxic microenvironment is crucial for grasping tumor biology, clinical progression, and treatment responses. This study presents a novel application of artificial intelligence in computational histopathology to evaluate hypoxia in breast cancer. Weakly supervised deep learning models can accurately detect morphologic changes associated with hypoxia in routine hematoxylin and eosin (H&E)-stained whole slide images (WSIs).

Purpose: The routine perioperative use of opioids has recently been questioned due to opioid-related side effects, which can be potentially harmful in geriatric patients. This study aimed to evaluate the effects of opioid-free anesthesia in geriatric patients undergoing hip surgery.
Patients And Methods: A total of 121 patients, aged 60 years or older, undergoing elective hip surgery were randomized to receive either opioid-free anesthesia with dexmedetomidine and esketamine (OFA group) or balanced anesthesia with opioids (CON group).
Clearing the Air on the Efficacy of Hypoxia Recognition Training.

November 2024
Hypoxia recognition training (HRT) is a requirement for many nations' military aircrew. The aim of HRT is to enhance the ability of aircrew to recognize and recover from an unexpected in-flight hypoxic exposure; however, there is a paucity of research evaluating the efficacy of HRT and whether current training approaches are optimal. Rather, the benefits of HRT are routinely promulgated based on opinions and anecdotes.
