Abstract

Background: The safety of performing spinal anaesthesia for both patients and anaesthetists alike in the presence of active infection with the novel coronavirus disease 2019 (COVID-19) is unclear. Here, we report the clinical characteristics and outcomes for both patients with COVID-19 and the anaesthetists who provided their spinal anaesthesia.

Methods: Forty-nine patients with radiologically confirmed COVID-19 for Caesarean section or lower-limb surgery undergoing spinal anaesthesia in Zhongnan Hospital, Wuhan, China participated in this retrospective study. Clinical characteristics and perioperative outcomes were recorded. For anaesthesiologists exposed to patients with COVID-19 by providing spinal anaesthesia, the level of personal protective equipment (PPE) used, clinical outcomes (pulmonary CT scans), and confirmed COVID-19 transmission rates (polymerase chain reaction [PCR]) were reviewed.

Results: Forty-nine patients with COVID-19 requiring supplementary oxygen before surgery had spinal anaesthesia (ropivacaine 0.75%), chiefly for Caesarean section (45/49 [91%]). Spinal anaesthesia was not associated with cardiorespiratory compromise intraoperatively. No patients subsequently developed severe pneumonia. Of 44 anaesthetists, 37 (84.1%) provided spinal anaesthesia using Level 3 PPE. Coronavirus disease 2019 infection was subsequently confirmed by PCR in 5/44 (11.4%) anaesthetists. One (2.7%) of 37 anaesthetists who wore Level 3 PPE developed PCR-confirmed COVID-19 compared with 4/7 (57.1%) anaesthetists who had Level 1 protection in the operating theatre (relative risk reduction: 95.3% [95% confidence intervals: 63.7-99.4]; P<0.01).

Conclusions: Spinal anaesthesia was delivered safely in patients with active COVID-19 infection, the majority of whom had Caesarean sections. Level 3 PPE appears to reduce the risk of transmission to anaesthetists who are exposed to mildly symptomatic surgical patients.
