Portable Handheld Point-of-Care Ultrasound for Detecting Unrecognized Esophageal Intubations.
Esophageal intubations are not an uncommon occurrence in prehospital settings, occurring as high as 17%. These "never events" are associated with significant morbidity and mortality especially when unrecognized or when there is delayed recognition. Here, we review the currently available techniques for confirming endotracheal tube intubation and their limitations, and present the case for the application of portable handheld point-of-care ultrasound as an emerging technology for detection of potentially unrecognized esophageal intubations such as during cardiac arrest. We also provide algorithms for confirmation of tracheal intubation.

A Decision Tree Approach to Airway Management Pathways in the 2022 Difficult Airway Algorithm of the American Society of Anesthesiologists.
The American Society of Anesthesiologists' (ASA) Task Force on Management of the Difficult Airway has developed a decision tree tool that uses inductive assessments to guide the anesthesiologist's choice of pathway in the ASA's Difficult Airway Algorithm. The tool prompts the anesthesiologist to consider the risk of difficulty with laryngoscopy (direct or indirect) and tracheal intubation, facemask or supraglottic ventilation, gastric contents aspiration, and rapid oxyhemoglobin desaturation. ⋯ Entry into the awake intubation pathway is encouraged when the patient is judged at risk of difficult tracheal intubation and one or more of the following: difficult ventilation, significant aspiration risk, and/or rapid oxyhemoglobin desaturation. The decision tree tool is anticipated to improve communication between anesthesiologists and others by clearly identifying those factors of concern and how decision-making is affected by those concerns.

A 31-year-old G2P1 (gravida 2 para 1) woman at 34 weeks of gestation presented after a motor vehicle collision with an incomplete cervical spinal cord injury. The patient underwent emergent anterior cervical decompression and fusion (ACDF), immediately followed by cesarean delivery. We discuss the clinical decision making to perform ACDF first, weighing risks and benefits to both mother and baby. We also address important anesthetic considerations for this pregnant patient having emergent spine surgery, including positioning with left uterine displacement, rapid sequence intubation to minimize aspiration risk, choice of vasopressor, implications of total intravenous maintenance anesthetic, and the medical teams involved in this care.

The optimal noninvasive modality for oxygenation support in COVID-19-associated hypoxemic respiratory failure and its association with healthcare worker infection remain uncertain. We report here our experience using high-flow nasal oxygen (HFNO) as the primary support mode for patients with COVID-19 in our institution. ⋯ Our experience indicates that HFNO is an effective first-line therapy for hypoxemic respiratory failure in COVID-19 patients, and can be safely used without significant discernable infection risk to healthcare workers.
