There has been a substantial burden of healthcare worker infection during the current coronavirus (COVID-19) pandemic, likely due to a lack of adequate preparedness, suboptimal institutional infection control measures, atypical patient presentation, poor compliance with personal protective equipment (PPE) and exposure to high-risk aerosol generating procedures, such as endotracheal intubation. There is significant concern that developing countries will face heightened levels of staff exposure during the COVID-19 pandemic. ⋯ However, in practice these boxes were found to hamper endotracheal intubation and other procedures due to the limited space and manoeuvrability they allow. To further reduce particle dispersion and to improve on the practicality and ergonomic design of the prototype "aerosol box", the Intubox was developed by staff at the Charlotte Maxeke Johannesburg Academic Hospital after instituting several changes to the prototype design.

The unexpected problematic airway represents a large proportion of anesthesia-related morbidity and mortality. The retromolar or paraglossal approach is an alternative to the majority of the rigid instruments used for tracheal intubation, which follow the midline to access the glottis. This single-center, prospective case-series study offers an option to conventional laryngoscopy in case of a poor glottic view, introducing an instrument (the rigid tube for laryngoscopy) that uses the retromolar approach to accomplish tracheal intubation. ⋯ This tool was tested on 30 patients with an unsatisfactory glottic view when using the Macintosh laryngoscope and obtained excellent results with respect to intubation time and complications. The reduced visual field is the main limitation of this method, which requires a training period for reasonable expertise. This simple, robust, and cheap instrument could be a rescue option in case of a difficult airway.

Those involved in the airway management of COVID-19 patients are particularly at risk. Here, we describe a practical, stepwise protocol for safe in-hospital airway management in patients with suspected or confirmed COVID-19 infection.

Randomized Controlled Trial Comparative Study Observational Study
Comparison of gastric insufflation using LMA-supreme and I-gel versus tracheal intubation in laparoscopic gynecological surgery by ultrasound: a randomized observational trial.
The application of bedside ultrasound to evaluate gastric content and volume can assist in determining aspiration risk. Applying positive pressure ventilation via supraglottic airway devices (SAD) can result in a degree of gastric insufflation. This study assessed and compared the antral cross-sectional area (CSA) in patients undergoing laparoscopic gynecological surgery when managed with different SAD. ⋯ The SADs do not cause obvious gastric insufflation. Thus, LMA-Supreme and I-gel can be widely used as alternative to endotracheal intubation for the short laparoscopic gynecological surgery.
