Peripheral branch of the radial nerve injury after venipuncture and sedation for surgical intervention

Abstract

In May 2024, DATASUS recorded 6,334 hospitalizations for surgical complications in the SUS, with 21% related to ulnar nerve injuries, according to the literature. Nerve injuries are classified into neuropraxia, axoniotmesis, and neurotmesis, according to severity. The radial nerve, located in the upper limb, can be affected by injuries during surgery or the patient's positioning. The American Society of Anesthesiologists emphasizes the importance of positioning and anatomical knowledge to avoid these injuries. Peripheral venous access, which is widely used, can result in nerve injuries, which are often underdiagnosed. Although peripheral venipuncture can cause complications, injuries are usually treatable and full recovery is possible with conservative treatment.
