Critical care medicine is a specialty that brings together a truly wide spectrum of patient populations, disease states, and treatment methods. This article highlights 10 important pieces of research from 2023 (and 1 from 2022) in critical care. ⋯ Topics include transfusion medicine, fluid resuscitation, safe intubation practices and respiratory failure, and the management of acute ischemic stroke. Several trials are groundbreaking, forcing clinicians to reconsider preexisting dogma and likely adopt new treatment strategies.

Observational Study
Determinants of difficult laryngoscopy based on upper airway indicators: a prospective observational study.
The main cause of anesthesia-related deaths is the failure to manage difficult airways. Difficult laryngoscopic exposure is a major cause of unsuccessful management of difficult airways. Inadequate preoperative airway assessment hinders the clinical management of difficult airways cases, emphasizing the critical need for accurate identification of difficult airways. Currently, no definitive and reliable indicators are available to predict a difficult airway. Our study aims to predict laryngoscope exposure risk factors by combining ultrasonically measured upper airway anatomic parameters with physical examination indicators. ⋯ Our findings revealed a direct correlation between difficult laryngoscopy and age, BMI, neck circumference, neck mobility, snoring intensity, as well as ultrasound measurements of the pre-epiglottic space and thyromental distance. Furthermore, neck mobility was identified as an independent predictive factor.

Double lumen endobronchial tubes (DLTs) are frequently used to employ single lung ventilation strategies during thoracic surgical procedures. Placement of these tubes can be challenging even for experienced clinicians. We hypothesized that airway anatomy, particularly of the glottis and proximal trachea, significantly impacts the ease or difficulty in placement of these tubes. ⋯ Rotation of DLTs a full 180 instead of the recommended 90 degrees facilitates DLT intubations.
