  ABSTRACT: Background: Hypnosis monitoring has been shown to reduce the incidence of awareness. A-line ARX-IndexTM (AAI) derived from auditory evoked potentials (AEP) represents as a numerical variable depth of anaesthesia. Objectives: To study the efficacy of AEP as an indicator of anaesthetic depth and monitor intraoperative awareness in neurosurgical patients by using the AAI scale. Design: Prospective cohort study is used. Setting: The study is in Neurosurgical centre of Tertiary care hospital. Participants: Neurosurgical patients requiring general anaesthesia with duration of surgery between 90 - 150 minutes were enrolled for the study. Intervention: Patients in Group 1 (control) were monitored by conventional methods. Patients in Group 2 (study) underwent intraoperative monitoring by using the AEP monitor. Primary outcome: To study the efficacy of AEP monitoring and AAI index for monitoring the depth of anaesthesia and reducing the incidence of awareness. Results: There was no significant difference in the intraoperative haemodynamic responses measured between the two study groups (p > 0.5). There was no significant difference in the identification of intraoperative awareness by using conventional parameters between the two groups (p > 0.5). There was also a significantly faster time to recovery for patients in Group 2 (p
