Intra-operative neurophysiological monitoring (IONM) & its role in neurosurgeries: An exceedingly essential monitoring technique

Abstract

Balanced anaesthesia with intra-operative neuro monitoring (IONM) is an ideal choice for neurosurgeries wherein the functionalities of nerve has to be ascertained. The optimum goals during neurosurgeries include maintaining normothermia, hemodynamic parameters and blood loss. Neurophysiological monitoring consisting but not limited to evoked potentials originating from motor, somatosensory areas has become an indispensable tool in neurosurgeries to prevent nerve injuries and paralysis. This case describes the anaesthesia considerations in a case of laminectomy where IONM was used. The anaesthesiologist must have adequate knowledge regarding IONM to avoid interference and signal alteration due to anaesthesia. Hence, a proper teamwork is required between the anaesthesiologist, surgeon and neurophysiologist in order to provide a high-quality perioperative care and to detect and prevent neurological injuries.
