Since the advent of anaesthesia in 1846, ensuring adequate depth has been a major concern of anaesthesiologists to prevent awareness without inadvertently overloading the patients with potent drugs. The aim of this prospective comparative study was to evaluate and correlate the efficacy of Bispectral index monitoring along with PRST score in assessment of depth of anaesthesia. A total of 100 patients were included in this study undergoing surgery under general anaesthesia. Patients were included randomly in group 1(Depth of anaesthesia assessed by PRST score) and group 2 (Depth of anaesthesia was assessed by PRST score along with BIS index monitoring). The distribution of mean PRST score at T1, T2, T3, T4 and T5 was significantly higher in group 1 (Depth of anaesthesia was assessed by PRST score) as compared to group 2. Intraoperative BIS values were maintained between 40 – 60 and no post-operative awareness was detected in either of the groups. When BIS values are maintained between 40 – 60, patients are more hemodynamically stable. Bispectral index monitoring allows anaesthesiologist to directly and accurately monitor the hypnotic effect of anaesthesia.
