Abstract

According to the studies, the incidence of anesthesia-related nerve injury associated with peripheral nerve blocks (PNBs) is 0.4%, which is likely that the commonly cited is underestimated due to underreport. In addition, most complications of PNBs were reported with upper extremity blocks. The mechanisms of injury are including intraneural injuries, vascular mediated lesions, pressure, pain of injection, resistance to injection and needle designs and trauma. Anesthesia-related nerve injury can classify in three types of Neuropraxia, Axonotmesis and neurotmesis. Electrophysiology testing (NCS, EMG), Doppler Ultrasound/High-Frequency Ultrasound and Magnetic Resonance Neurography are common tests used for diagnosis of this type of injury. It can be concluded that anesthesia-related nerve injury associated with should be considered during the PNBs procedures.
