Pre-Anesthesia Re-Evaluation in Post COVID-19 Patients Posted for Elective Surgeries: an Online, Cross-Sectional Survey.

Multiple studies have reported the increased risk of pulmonary complications and mortality in patients undergoing surgery with perioperative COVID-19 infection. With several reports of long-term sequelae in patients recovered from COVID-19 infection, this survey was conducted to collect the opinions of anesthesiologists regarding modifications to pre-anesthesia checkup (PAC) when COVID-19 survivors are posted for elective surgeries. We designed, validated and distributed a detailed online questionnaire, about various modifications in PAC in different patient populations like asymptomatic patients, patients with mild, moderate or severe hypoxia, significant cardiac complaints during COVID-19 and also geriatric, pediatric and pregnant patients with a history of COVID-19. We received 154 responses. Majority of responders agree that 0–2 weeks from the date of negative for SARS-CoV-2, is the ideal duration for all elective surgeries. Greater than 50% responders agree that a fresh PAC evaluation should be done for such patients which should include documentation of current functional status, fresh chest X-ray, electrocardiogram and coagulation profile. All patients who had hypoxia or cardiac symptoms during COVID-19 infection and even recovered asymptomatic geriatric patients should undergo cardiorespiratory evaluation with investigations such as HRCT chest, ABG, PFT, echocardiography and troponin I levels. Patients’ PAC should be individualized, factoring in the severity of COVID-19 infection, post recovery functional status, associated co-morbidities and the urgency as well as the risk of surgical intervention.
