Observational StudyIntraoperative Electroencephalography Alpha-Band Power Is a Better Proxy for Preoperative Low MoCA Under Propofol Compared With Sevoflurane.
Preoperative abnormal cognitive status is a risk factor for postoperative complications yet remains underdiagnosed. During propofol general anesthesia, intraoperative electroencephalography (EEG) variables, such as alpha band power (α-BP), correlate with cognitive status. This relationship under sevoflurane is unclear. We investigated whether EEG biomarkers of poor cognitive status found under propofol could be extended to sevoflurane. ⋯ We suggest that intraoperative EEG biomarkers of abnormal cognition differ between propofol and sevoflurane under general anesthesia.

Inadequate neuraxial anaesthesia during caesarean delivery: a survey of practitioners.
We aimed to determine the knowledge, training, practices and attitudes of obstetric anaesthetic practitioners with regard to failed neuraxial anaesthesia for caesarean delivery. ⋯ Our study survey found that the consent process may not always be adequately comprehensive, and that standardised documentation and testing of the block and focused training may be beneficial to prevent patient dissatisfaction and the chance of litigation.

Postoperative respiratory failure is a major surgical complication and key quality metric. Existing prediction tools underperform, are limited to specific populations, and necessitate manual calculation. This limits their implementation. We aimed to create an improved, machine learning powered prediction tool with ideal characteristics for automated calculation. ⋯ We developed a general-purpose, machine learning powered prediction tool with superior performance for research and quality-based definitions of postoperative respiratory failure.

To determine the association between the presence of upper respiratory tract viral infection symptoms and occurrence of perioperative respiratory adverse events (PRAE) in children with positive viral screening, and to analyze the risk of PRAE in children with SARS-CoV-2 compared to non-SARS-CoV-2 infection. ⋯ There was no significant difference in the incidence of PRAE between symptomatic and asymptomatic children with laboratory confirmed viral respiratory infection, and between children with the Omicron variant of SARS-CoV-2 compared to non-SARS-CoV-2 respiratory viruses. However, the risk was increased in children with recent fever.

Observational StudyTracheal Narrowing and Its Impact on Anesthesia Care in Patients With Morquio A (Mucopolysaccharidosis Type IVA): An Observational Study.
Recently, tracheal narrowing has been recognized as a significant comorbid condition in patients with Morquio A, also known as mucopolysaccharidosis IVA. We studied a large cohort of patients with Morquio A to describe the extent of their tracheal narrowing and its relationship to airway management during anesthesia care. ⋯ Clinically significant tracheal narrowing was present in patients with Morquio A, and the degree of such narrowing likely contributed to the difficulty with airway management during their anesthetic care. Tracheal narrowing worsens with age, but the progression appears to slow down after 20 years of age. In addition to tracheal narrowing, spirometry values of FEF25%-75% may be helpful in the overall evaluation of the airway in patients with Morquio A.
