RESUMO
Combined regional anesthesia is frequently used as a tool for management of postoperative pain. The profile of side effects of the opioids used via this route is similar to those occurring after systemic administration. The onset of vertigo with vertical nystagmus is an adverse effect rarely described after the use of intrathecal, epidural or intravenous morphine. We report the case of a patient who presented this complication in the postoperative period of a partial nephrectomy, after the administration of intrathecal morphine, with complete resolution by intravenous naloxone.

La anestesia regional combinada es utilizada frecuentemente como herramienta para el tratamiento del dolor postoperatorio. Los efectos secundarios de los opioides utilizados por esta vía son similares a los que se presentan luego de la administración sistémica. La aparición de vértigo con nistagmo vertical es un efecto adverso muy pocas veces descripto con el uso de morfina por vía intratecal, epidural o endovenosa. Comunicamos el caso de un paciente que presentó esta complicación en el postoperatorio de una nefrectomía parcial, luego de la administración de morfina intratecal, con resolución completa mediante el uso de naloxona endovenosa.
