Under simulated conditions perspex aerosol intubating boxes increased intubation time, decreased first-pass intubation success, and increased PPE breaches. Their use during the COVID pandemic cannot be recommended.

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.

The world is currently facing an unprecedented healthcare crisis caused by a pandemic novel beta coronavirus, severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The pathogen is spread by human-to-human transmission via droplets exposure and contact transfer, causing mild symptoms in the majority of cases, but critical illness, bilateral viral pneumonia, and acute respiratory distress syndrome (ARDS) in a minority. ⋯ This article presents a summary of learning points in epidemiological infection control from the SARS epidemic, alongside a review of evidence connecting current understanding of the virologic and environmental contamination properties of SARS-CoV-2. We present suggestions for how personal protective equipment policies relate to the viral pandemic context and how the risk of transmission by and to anaesthetists, intensivists, and other healthcare workers can be minimised.

Determinants of fatigue in emergency department clinicians who wear personal protective equipment.
To determine the independent predictors for clinician fatigue and decline in cognitive function following a shift in the ED during early stages of the COVID-19 pandemic. ⋯ Working afternoon shifts was associated with fatigue. There was no association between HRZ allocation and fatigue, but our study was limited by a low COVID workload and fluctuating PPE requirements in the non-HRZs. Workplace interventions that target the prevention of fatigue in ED clinicians working afternoon shifts should be prioritised.

Multicenter Study Observational Study
Real-world comparison between mechanical and manual cardiopulmonary resuscitation during the COVID-19 pandemic.
The COVID-19 pandemic has posed significant challenges to healthcare systems worldwide, including an increase in out-of-hospital cardiac arrests (OHCA). Healthcare providers are now required to use personal protective equipment (PPE) during cardiopulmonary resuscitation (CPR). Additionally, mechanical CPR devices have been introduced to reduce the number of personnel required for resuscitation. This study aimed to compare the outcomes of CPR performed with a mechanical device and the outcomes of manual CPR performed by personnel wearing PPE. ⋯ This study found no significant differences in survival rates and neurological outcomes between mechanical CPR and PPE-equipped manual CPR in the ED setting. However, a longer total CPR duration was observed in the mechanical CPR group. Further research is required to explore the impact of PPE on healthcare providers' performance and fatigue during CPR in the context of the pandemic and beyond.
