Usefulness of Intravenous Regional Anesthesia for Upper Extremity Arterial Injury Emergencies in Patients with COVID-19: A Case Series and Literature Review

Abstract

The medical field has undergone many changes since the start of the coronavirus disease 19 (COVID-19) pandemic. In small- and medium-sized hospitals that lack negative pressure facilities for operating rooms, it is impossible to operate on patients infected with COVID-19. As a result, many patients requiring emergency surgery experience serious complications or die. The authors performed intravenous regional anesthesia (IVRA) and emergency surgery in an isolation room on three patients who needed prompt surgical management for upper extremity arterial injuries but could not enter the operating room due to COVID-19 infection. Anesthesia was successful in all cases. A minor anesthetic complication occurred in one patient, who recovered spontaneously. IVRA is a relatively safe and easy method for anesthesia. Moreover, since the tourniquet is inflated before anesthesia, it is well-suited for patients with arterial injury. The method is simple and therefore easy to perform in an isolation room where space and manpower are limited. IVRA can be a good option in emergency surgery for upper extremity artery injury.
