While the anatomically difficult airway has been studied in pediatric trauma patients, physiologic risk factors are poorly understood. Our objective was to evaluate if previously published high risk physiologic criteria for difficult airway in medical patients is associated with adverse outcomes in pediatric trauma patients. ⋯ The presence of high risk physiologic criteria is associated with increased incidence of peri-intubation, in-hospital arrest, and death in pediatric trauma patients. Children with multiple risk factors are at an incremental risk of cardiac arrest.

Emergency airway management requires matching the appropriate intubation tools to anticipated obstacles. Video laryngoscopy and flexible endoscopy are often used for difficult airways. Here we describe a case where neither method alone was anticipated to be sufficient. ⋯ The patient could not be temporized on maximized non-invasive airway support. These factors made tandem intubation, sequentially using video laryngoscopy and flexible endoscopic intubation, an appropriate intubation strategy. In this case report we describe the rationale and technique for a rapid sequence tandem intubation.

A hood shield reduces postdoffing contamination during simulated COVID-19 airway management: an exploratory, simulation-based randomized study.
SARS-CoV-2 poses a significant occupational health threat to health care workers performing aerosol-generating medical procedures, with a threefold increased risk of a positive test and predicted infection compared with the general population. Nevertheless, the personal protective equipment (PPE) configuration that provides better protection with lower contamination rates is still unknown. ⋯ ClinicalTrials.gov (NCT04373096); registered 4 May 2020.

Aerosol-generating procedures are medical interventions considered high risk for transmission of airborne pathogens. Tracheal intubation of anaesthetised patients is not high risk for aerosol generation; however, patients often perform respiratory manoeuvres during awake tracheal intubation which may generate aerosol. To assess the risk, we undertook aerosol monitoring during a series of awake tracheal intubations and nasendoscopies in healthy participants. ⋯ Awake tracheal intubation and nasendoscopy can generate high concentrations of respiratory aerosol. Specific risks are associated with lidocaine spray of the larynx, instrumentation of the vocal cords, procedural coughing and deep breaths. Given the proximity of practitioners to patient-generated aerosol, airborne infection control precautions are appropriate when undertaking awake upper airway endoscopy (including awake tracheal intubation, nasendoscopy and bronchoscopy) if respirable pathogens cannot be confidently excluded.

Predicting a difficult airway, including difficult laryngoscopy, intubation or mask ventilation, is paramount in peri-operative management. As clinical predictors are only partially reliable, ultrasound-based measurements might be useful in evaluating anterior neck fat tissues depth. ⋯ CRD42021250574.
