Guideline: SARS‐CoV‐2 infection, COVID‐19 and timing of elective surgery

Study from 116 countries suggests surgery should be delayed for at least seven weeks following a COVID-19 diagnosis to reduce mortality risk

BJS commission on surgery and perioperative care post-COVID-19.

The risk of postoperative complications following major elective surgery in active or resolved COVID-19 in the United States – Major, elective surgery 0–4 weeks after Covid-19 is associated with greatly increased risk of postoperative complications; surgery performed 4–8 weeks after infection is still associated with an increased risk of pneumonia.

ASA Guidance: Preoperative testing for COVID-19 is essential, regardless of vaccination.

Position statement: Perioperative management of post-COVID-19 surgical patients.

Cohort study: Postoperative in-hospital mortality of patients with COVID-19 infection was more than double that in patients without COVID-19

Risks of myocarditis, pericarditis, and cardiac arrhythmias associated with COVID-19 vaccination vs. SARS-CoV-2 infection.

Case series with 139 adolescents and young adults with suspected myocarditis following mRNA vaccination showed most cases had a mild clinical course and rapid resolution of symptoms.

Heart-inflammation risk from Pfizer COVID vaccine is very low.

Large cohort study with over 2.5 million individuals showed the incidence of myocarditis after the Pfizer vaccine was 2.13 cases per 100,000 persons.

Study with over 5.1 million vaccinated individuals showed the incidence of myocarditis after the receipt of the Pfizer vaccine was low and more common after the second dose in young male recipients.

Large Observational study shows Pfizer Covid vaccine is mostly safe but is associated with increased risk of myocarditis, adenopathy, appendicitis, and herpes zoster.
