Editorial
Kicking on while it's still kicking off - getting surgery and anaesthesia restarted after COVID-19.
Cook and Harrop-Griffiths survey the damage of a health system stretched to its limits in response to the UK's COVID-19 crisis, and how elective surgery could be carefully recommenced – particularly considering that the pandemic is far from over.
"....this has been achieved ‘by the skin of our teeth’ and until very recently, the threat of insufficient ICU beds, ventilators, and the need for triage were all anticipated: a few hospitals were overcome by the surge of critically ill patents."
They highlight several priorities as the NHS looks to return to a 'new normal' of healthcare provision:
- Support ICU needs of those with COVID.
- Make hospitals safe for patients both with and without COVID.
- Returning staff and services to pre-pandemic areas as possible.
- Protect staff with adequate personal protective equipment.
- Appropriate surgical case triage.
"Having weathered the COVID‐19 storm, we are now being asked to assess the damage done, pick up the pieces and rebuild. However, this storm will rage for many months. Flattening the epidemic curve does not reduce the total number of cases but spread their burden over a longer period of time..."
Of particularly note is the challenge of ensuring COVID positive patients do not undergo non-essential surgery, known to be associated with a high post-operative mortality. They explore the complexities of pre-operative isolation and testing (PCR or CT), and the inherent limitations of these.
summary"The move from a health service focused on one single disease to one that continues that challenge while also addressing all the other health needs of the population may be even harder than that the crisis phase that preceded it."

Review Meta Analysis
Outcomes from intensive care in patients with COVID-19: a systematic review and meta-analysis of observational studies.
The emergence of coronavirus disease 2019 (COVID-19) has led to high demand for intensive care services worldwide. However, the mortality of patients admitted to the intensive care unit (ICU) with COVID-19 is unclear. Here, we perform a systematic review and meta-analysis, in line with PRISMA guidelines, to assess the reported ICU mortality for patients with confirmed COVID-19. ⋯ As the pandemic has progressed, the reported mortality rates have fallen from above 50% to close to 40%. The in-ICU mortality from COVID-19 is higher than usually seen in ICU admissions with other viral pneumonias. Importantly, the mortality from completed episodes of ICU differs considerably from the crude mortality rates in some early reports.

Randomized Controlled Trial
The impact of respiratory protective equipment on difficult airway management: a randomised, crossover, simulation study.
The current international COVID-19 health crisis underlines the importance of adequate and suitable personal protective equipment for clinical staff during acute airway management. This study compares the impacts of standard air-purifying respirators and powered air-purifying respirators during simulated difficult airway scenarios. Twenty-five anaesthetists carried out four different standardised difficult intubation drills, either unprotected (control), or wearing a standard or a powered respirator. ⋯ Videolaryngoscopy allowed the shortest intubation times regardless of the respiratory protective device used. Anaesthetists rated heat and vision significantly higher in the powered respirator group; however, noise levels were perceived to be significantly lower than in the standard respirator group. We conclude that standard and powered respirators do not significantly prolong simulated advanced intubation procedures.

Coronavirus disease 2019 (COVID-19) has had a significant impact on global healthcare services. In an attempt to limit the spread of infection and to preserve healthcare resources, one commonly used strategy has been to postpone elective surgery, whilst maintaining the provision of anaesthetic care for urgent and emergency surgery. General anaesthesia with airway intervention leads to aerosol generation, which increases the risk of COVID-19 contamination in operating rooms and significantly exposes the healthcare teams to COVID-19 infection during both tracheal intubation and extubation. ⋯ The goal of this review is to provide up-to-date, evidence-based recommendations or expert opinion when evidence is limited, for performing regional anaesthesia procedures in patients with suspected or confirmed COVID-19 infection. These recommendations focus on seven specific domains including: planning of resources and staffing; modifying the clinical environment; preparing equipment, supplies and drugs; selecting appropriate personal protective equipment; providing adequate oxygen therapy; assessing for and safely performing regional anaesthesia procedures; and monitoring during the conduct of anaesthesia and post-anaesthetic care. Implicit in these recommendations is preserving patient safety whilst protecting healthcare providers from possible exposure.

The COVID-19 pandemic marks an extraordinary global public health crisis unseen in the last century, with its rapid spread worldwide and associated mortality burden. The longevity of the crisis and disruption to normality is unknown. With COVID-19 set to be a chronic health crisis, clinicians will be required to maintain a state of high alert for an extended period. ⋯ It highlights various individual as well as organisational strategies. With the success of slowing disease spread in many countries to date, and reduced work-load due to limitations on elective surgery in many institutions, there is more time and opportunity to be pro-active in implementing measures to mitigate or minimise potential adverse psychological effects and improve, restore and preserve the well-being of the workforce now and for years to come. The purpose of this review is to review available literature on strategies for minimising the psychological impact of the COVID-19 pandemic on clinicians and to identify pro-active holistic approaches which may be beneficial for healthcare workers both for the current crisis and into the future.
