ABSTRACT
Background: Globally critically ill COVID-19 (Coronavirus disease-19) patients have stretched critical care services. This study was undertaken to find factors implicated in mortality amongst COVID positive and negative patients presenting with severe acute respiratory illness (SARI) and factors having the probability of indicating COVID positivity. Methods: The demographic parameters, comorbid illness, clinical parameters and laboratory values of 327 patients were retrospectively analyzed to find the risk factors for mortality in COVID positive and negative patients and factors predicting COVID positivity amongst SARI patients. Results: 58% of SARI patients tested positive by RTPCR. Most common comorbidities were diabetes and hypertension, 35.2% and 33% respectively. Duration of swelling and low haemoglobin were significantly associated with mortality in COVID positive group (p=0.01, 0.005). Acidosis and tachycardia (p=0.003, 0.034) were associated with mortality amongst COVID negative. Creatinine, Sequential Organ Failure Assessment (SOFA) and quick SOFA (qSOFA) were higher in non-survivors of both groups (p<0.001). Age, history of contact or from containment zone, cough, pain abdomen and P/F ratio were significant predictors of COVID positivity (1.020(1.006–1.035);3.889(1.316–11.495);2.908(1.182–7.152);2.147(1.149–4.012);0.997(0.994-1.000) respectively) by multivariable regression analysis. Conclusion: A long duration of swelling and low haemoglobin (<12 g%) were responsible for COVID positive mortality while pain abdomen, raised levels of AST, tachycardia and acidosis were associated with mortality in COVID negative. Deranged creatinine, higher SOFA and qSOFA were associated with mortality in both groups. Age, contact history, residence in containment zone, cough, pain abdomen and poor P/F ratio are predictive factors for COVID positivity. © 2023 Tehran University of Medical Sciences.

ABSTRACT
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. Therefore, the provision of regional anaesthesia may be key during this pandemic, as it may reduce the need for general anaesthesia and the associated risk from aerosol-generating procedures. However, guidelines on the safe performance of regional anaesthesia in light of the COVID-19 pandemic are limited. 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.
