AbstractStudy objective  Analysis of emergency cases performed during initial coronavirus disease 2019 (COVID-19) pandemic and the proportion completed under regional anesthesia (RA). Design Cohort study comparing surgical caseload during initial seven-week COVID-19 pandemic in 2020. Comparison was made with pre-COVID-19 caseload over the corresponding seven-week timeframe in 2019. Setting The setting of the study was emergency surgery theaters at Guy's and St Thomas' NHS Foundation Trust, London, UK. Patients All patients requiring emergency surgery over the defined study period were reviewed with the exception of obstetric and pediatric populations. Interventions Surgical caseload for 2020 and 2019 cohorts established using the Galaxy IT system used to log all operations. All relevant anesthetic charts for the 2020 cohort were subsequently reviewed to ascertain perioperative use of RA. Measurements The type of block, mode of approach, experience of the operator, personal protective equipment (PPE) worn, block complications, type of sedation and complications were entered into database. Main results A total of 338 emergency surgical cases were performed during the COVID-19 pandemic in 2020, compared to 603 cases over the corresponding period in 2019. This showed a 44% decrease in emergency surgical workload. There was a marked disparity in reduction of surgical caseload by surgical subspecialty. Trauma (137 vs 66 cases), a 52% decrease, and general surgery (193 vs 64 cases), a 66% decrease, were the most pronounced, and explanations for this are explored. RA was performed in 34% (26% as primary technique) of cases during the COVID-19 pandemic. The use of RA as the primary anesthesia technique was noticeably higher than previous UK data (11%), and was prominent in specialties such as general surgery, gynecology and urology, not traditionally completed under RA. Conclusions Surgical RA (and general anesthesia avoidance) has a significant role in the future to ensure high-quality perioperative care for patients whilst minimizing exposure to staff and utilization of scarce resources (PPE).Copyright © 2020, Wade et al.
