Multicenter StudyApnea Testing Practice to Increase Baseline PaCO2 and Frequency of Blood Gas Analyses.
To study the influence of the initial partial pressure of carbon dioxide (PaCO2) and frequency of blood gas analyses on the positivity rate and safety of apnea testing (AT). ⋯ Increasing the baseline PaCO2 and doing more blood gas analyses can significantly shorten the time needed for AT and improve the AT positivity rate.

Multicenter Study Observational StudyAbnormal Iron Status and Adverse Outcome After Elective Cardiac Surgery: A Prospective, Observational Multicenter Study.
To investigate the incidence of preoperative abnormal iron status and its association with packed red blood cell (PRBC) transfusion, postoperative major complications, and new onset of clinically significant disability in patients undergoing elective cardiac surgery. ⋯ An abnormal iron status before elective cardiac surgery was associated with an increased risk of postoperative major complications but not with PRBC transfusion or a new onset of clinically significant disability.

Randomized Controlled TrialComparison of an Ultrasound-Guided Dynamic Needle Tip Positioning Technique and a Long-Axis In-Plane Technique for Radial Artery Cannulation in Older Patients: A Prospective, Randomized, Controlled Study.
The authors compared the dynamic needle tip positioning (DNTP) technique and the long-axis in-plane (LAIP) technique in older patients. ⋯ The DNTP technique has better efficiency and safety than the LAIP technique for radial artery catheterization in the older population.

ReviewNeuraxial Anesthesia in Patients With Aortic Stenosis: A Systematic Review.
Neuraxial anesthesia (NA) has been contraindicated in patients with aortic stenosis (AS) due to concerns of sympathetic blockade and hemodynamic instability. These considerations are based on precautionary expert recommendations, supported by expected physiologic effects, but in the absence of any published scientific evidence. In light of the increasing elderly population and the prevalence of AS, this systematic review compiles available literature on NA in patients with AS to address the understanding of the anesthetic practice and safety in this population. ⋯ The relative risk of different AS severities remains unclear, and optimal medication dosing remains elusive. The authors' data suggested that NA may not be contraindicated in carefully selected patients with AS. The authors' results should inform the design of future prospective studies comparing NA and general anesthesia in patients with AS.

ReviewThe Promise of Artificial Intelligence-Assisted Point-of-Care Ultrasonography in Perioperative Care.
The role of point-of-care ultrasonography in the perioperative setting has expanded rapidly over recent years. Revolutionizing this technology further is integrating artificial intelligence to assist clinicians in optimizing images, identifying anomalies, performing automated measurements and calculations, and facilitating diagnoses. Artificial intelligence can increase point-of-care ultrasonography efficiency and accuracy, making it an even more valuable point-of-care tool. Given this topic's importance and ever-changing landscape, this review discusses the latest trends to serve as an introduction and update in this area.
