The COVID-19 pandemic has led to the production of novel devices intended to protect airway managers during the aerosol-generating procedure of tracheal intubation. Using an in-situ simulation model, we evaluated laryngoscopist exposure of airborne particles sized 0.3 - 5.0 microns using five aerosol containment devices (aerosol box; sealed box with and without suction; vertical drape; and horizontal drape) compared with no aerosol containment device. Nebulised saline was used as the aerosol-generating model for 300 s, at which point, the devices were removed to assess particle spread. ⋯ Compared with no device use, neither horizontal nor vertical drapes showed any difference in any particle size exposure at any time. Finally, when the patient coughed, use of the aerosol box resulted in a marked increase in airborne particle exposure compared with other devices or no device use. In conclusion, novel devices intended to protect the laryngoscopist require objective testing to ensure they are fit for purpose and do not result in increased airborne particle exposure.

ReviewUse of nasal high flow oxygen during acute respiratory failure.
Nasal high flow (NHF) has gained popularity among intensivists to manage patients with acute respiratory failure. An important literature has accompanied this evolution. In this review, an international panel of experts assessed potential benefits of NHF in different areas of acute respiratory failure management. ⋯ When intubation is required, NHF can be used to pre-oxygenate patients either alone or in combination with non-invasive ventilation (NIV). Similarly, NHF reduces reintubation alone in low-risk patients and in combination with NIV in high-risk patients. NHF may be used in the emergency department in patients who would not be offered intubation and can be better tolerated than NIV.

Intubation practices for children in emergency departments and intensive care units across Australia and New Zealand: A survey of medical staff.
Intubation of children in the emergency setting is a high-risk, low incidence event. Standardisation of clinical practice has been hampered by a lack of high-quality evidence to support one technique over another. The aim of the present study is to determine clinician preference in intubation practice of children in EDs and ICUs in Australia and New Zealand to provide baseline information to allow future targeted research focused on improving the safety and efficacy of paediatric emergency airway management. ⋯ Within Australia and New Zealand there is considerable variation in paediatric emergency airway clinical practice, in particular with respect to pre-oxygenation, apnoeic oxygenation and use of video laryngoscopy. Definitive clinical trials are required to best inform clinical practice in this area.

Multicenter StudyRescue Intubation in the Emergency Department After Prehospital Ketamine Administration for Agitation.
Prehospital intramuscular (IM) ketamine is increasingly used for chemical restraint of agitated patients. However, few studies have assessed emergency department (ED) follow-up of patients receiving prehospital ketamine for this indication, with previous reports suggesting a high rate of post-administration intubation. This study examines the rate of and reasons for intubation and other airway interventions in agitated patients who received ketamine by Emergency Medical Services (EMS). ⋯ The observed rate of intubation in patients receiving prehospital ketamine for agitation was 16.3%. Study data did not reveal an age or dose-dependent rate of intubation. Further research should be conducted to compare the airway intervention rate of agitated patients receiving ketamine versus other sedatives in a controlled fashion.
