Pulmonary Complications and Mortality in Patients with SARS-CoV-2 Undergoing Elective and Emergent Hand Surgery.

ABSTRACT

Background Patients acutely infected with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) may have increased risk for postsurgical pulmonary complications and mortality, particularly with general anesthesia. Surgery is often delayed to mitigate risk; however, excessive delays may result in morbidity. Optimal criteria for delaying surgery in patients with or without symptoms are unknown. This study aimed to evaluate any complications following hand surgery in patients testing positive for SARS-CoV-2. Methods We retrospectively reviewed patients with a positive polymerase chain reaction test within 60 days before or after hand surgery between March 31, 2020 and March 31, 2021. Patients were telephoned also to supplement records. Type of surgery, type of anesthesia, comorbidities, timing of surgery, onset of symptoms, and complications were recorded. Results We identified 21 patients undergoing 26 procedures, of which 21 (81%) were emergency procedures and 5 (19%) were elective. Mean age was 37 years (range 17-71). General anesthesia was used in 88% of cases, with mean duration of 110 minutes. SARS-CoV-2 was diagnosed on average 6 days preoperatively (range 39 days preop-14 days postop). Positive tests were usually identified preoperatively (50%), versus day-of-surgery (25%) or postoperatively (25%). Patients were symptomatic in only 27% of cases, and completely asymptomatic in 73%. No asymptomatic patients developed complications. One patient suffered a fracture malunion after delayed surgery. Pulmonary complications were noted in 3 patients; all had prior pulmonary disease and underwent emergency surgeries under general anesthesia. Overall mortality rate was 0%. Conclusion Pulmonary complications and mortality are low following hand surgery in asymptomatic patients with a positive SARS-CoV-2 test.
