Risk of Postoperative Complications After Major Elective Surgery in Active or Resolved COVID-19

Abstract

1.1. Objective: To determine the affiliation among the timing of surgical procedure relative to the improvement of Covid-19 and the dangers of postoperative complications. 1.2. Background: It is unknown whether or not patients who recovered from Covid-19 after which underwent a prime elective operation have an increased danger of developing postoperative complications. 1.3. Material and Methods: The risk of postoperative complications for patients with Covid-19 research process, 18 primary forms of optionally available operations with inside the Covid-19 Research Database was evaluated the use of multivariable logistic regression. Patients were grouped through time of surgical procedure relative to Covid-19 infection i.e. 1. Pre-Covid-19: Surgical procedure performed earlier than January 2020 2. Peri-Covid-19: 0 to 4 weeks after Covid-19 infection 3. Early post-Covid-19: 4 to 8 weeks after infection 4. Late post-Covid-19: 8 weeks after infection. 1.4. Results: A total of 6479 patients who met study criteria were included in the study. Out of 6479 patients 3021 (46.6%) PeriCovid-19 had an elevated risk of developing postoperative pneumonia in 44(1.4%) patients, respiratory failure in 69(2%), pulmonary embolism in 23(0.5%), sepsis in 35(1.1%), arthythmia in 59(1.9%), renal failure in 75 (2.4%), UTI in 75(2.4%), DVT in 40(1.3%) patient’s respectively when compared to pre-Covid-19 patients. Early post-Covid-19 patients had an increased risk of developing postoperative pneumonia in 16 (2.9%), respiratory failure in 15(2.7%), pulmonary embolism in 7(1.2%), sepsis in 13(2.3%), arthythmia in 15(2.7%), renal failure in 13(2.3%), UTI in 17(3.1%), DVT in 10(1.8%) patients respectively when compared to pre-Covid-19 patients. Late post-Covid-19 patients did not have an increased risk of postoperative complications when compared to pre-Covid-19 patients. 1.5. Conclusions: Major, elective surgery 0 to 04 weeks after Covid-19 infection is related to an improved risk of postoperative complications. Surgery achieved four to eight weeks after Covid-19 infection remains related to an improved risk of postoperative pneumonia, while surgical treatment eight weeks after Covid-19 analysis is not related to improved complications.
