Coronavirus disease (COVID-19) was declared a pandemic by the World Health Organization on 11 March 2020 because of its rapid worldwide spread. In the operating room, as part of hospital outbreak response measures, anesthesiologists are required to have heightened precautions and tailor anesthetic practices to individual patients. In particular, by minimizing the many aerosol-generating procedures performed during general anesthesia, anesthesiologists can reduce exposure to patients' respiratory secretions and the risk of perioperative viral transmission to healthcare workers and other patients. ⋯ By doing so, we hope to address an issue that may have downstream implications in the way we practice infection control in anesthesia, with particular relevance to this new era of emerging infectious diseases and novel pathogens. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) is not the first, and certainly will not be the last novel virus that will lead to worldwide outbreaks. Having a well thought out regional anesthesia plan to manage these patients in this new normal will ensure the best possible outcome for both the patient and the perioperative management team.

Toronto anaesthesiologists Muñoz-Leyva & Niazi share observations from PPE training simulations, identifying the 'high risk' moments where frequent exposures and PPE failures are seen.
Why is this important?
For all the understandable concern over adequate access to PPE and discussion of appropriate levels of protection, HCW safety is entirely dependent on the effective use of this protective equipment.
Identifying common areas of 'biosafety breach' allows both clinicians and PPE supervisors to apply added attention to these steps. These areas can be conceptualised as offering a disproportionate safety benefit for the time and resources deployed in ensuring compliance at these moments.
Which areas did they identify as most important?
Donning
- N95 mask fit-testing and fit-checking; notably shaving facial hair to ensure a face-mask interface seal.
- Use of extended-cuff gloves with gown cuff tucked securely into glove.
- Time management: PPE donning should never be rushed, even in critical medical emergencies.
Doffing
- Glove removal is a high-risk step. When removing the second, inner glove, ensure as little contact as possible with the glove sleeve by the ungloved hand.
- Gown removal is the next highest risk step. Do not touch the front of the gown, especially with ungloved hands.
- Mask removal avoid touching front of mask; avoid any snapping of straps.
- Perform alcohol-based hand-hygiene after each article is removed.

Observational Study
Ultrasound assessment of gastric content in fasted patients before elective laparoscopic cholecystectomy: a prospective observational single-cohort study.
Patients with symptomatic gallbladder diseases exhibit delayed gastric emptying. We evaluated the residual gastric content in fasted patients scheduled for elective laparoscopic cholecystectomy because of symptomatic gallbladder disease using ultrasonography. ⋯ The gastric ultrasound assessment revealed that 13% of patients scheduled for elective cholecystectomy because of symptomatic gallbladder disease had a full stomach despite following the fasting guidelines. This was higher than the reported incidence of a full stomach among the general surgical population. Further studies are required to delineate the clinical implications of our findings.
