NITROUS OXIDE ANAESTHESIA INDUCED VITAMIN B12 DEFICIENCY PRESENTING AS ACUTE MYELONEUROPATHY
Keywords:

Abstract
Nitrous oxide (N2O) can precipitate vitamin B12 (cyanocobalamin) deficiency in susceptible individuals with borderline vitamin stores. We present a case of an alcohol-dependent patient who developed acute neurological symptoms following N2O anesthesia for mandibular surgery. Timely recognition and treatment resulted in complete neurological recovery. N2O induced acute neurological symptoms must be kept as an important differential diagnosis in at-risk patients who undergo surgery under general anesthesia.
