Retrospective Analysis of Surgical Patients During SARS - CoV-2 (COVID - 19) Omicron Surge in a Teaching University Hospital

Omicron surge during SARS - CoV - 2 (COVID) pandemic, presented with different characteristics in comparison to earlier surges due to other Variants of Concern (VoC). Parameters like surgical outcome, including prolonged ICU stay, post operative pulmonary complication and mortality were analysed.Methods: Patient data who underwent both elective and emergency surgeries were collected from 1st January 2022 to 31st March 2022 during Omicron wave in Kingdom of Bahrain were collected and analysed. Relevant data of patient were collected along with vaccination details, including, type of vaccination, number of doses received and number of booster doses.Results: Of the 81 patients who underwent major surgery, 12 were COVID positive and 69 were negative. Patients who were admitted to ICU admission (OR = 0.91 95% CI = (0.26-3.12) P = 0.88) , patients who underwent post operative ventilation ( OR = 0.92 95% CI = (0.26 - 3.21) P=0.90) and mortality (OR = 0.47 95% CI = (0.056 - 4.09) P=0.50) were not significantly different between COVID positive and negative patients. Similarly, those who underwent emergency surgery, 46/419 patients were COVID positive. Patients who were admitted to ICU admission (OR = 1.68 95% CI = (0.70 - 4.03) P = 0.24) P = 0.88) , patients who underwent post operative ventilation ( OR = 1.84 95% CI = (0.72 - 4.73) P=0.20) and mortality (OR = 0.465 95% CI = (0.006 - 3.58) P=0.46) were not significantly different between COVID positive and negative patients.Conclusion: In conclusion, patients who underwent elective and emergency surgery during Omicron wave were not associated with significant post operative ICU admission, prolonged ventilation or mortality.
