Background & Methods: The aim of the study is to Observation of BIS to assess the level of consciousness and depth of anaesthesia throughout the period of balanced general anaesthesia. During the above said study period, 100 patients posted for elective general
surgeries under general anaesthesia underwent continuous EEG analysis. Patients underwent routine pre- anaesthetic evaluation and routine NPO protocols. Results: Study population consisted of 100 ASA-PS I/II patients in the age group of 18- 60 years belonging to both sexes scheduled for elective general surgeries. After taking informed written consent, all the patients were taken up for the respective surgeries. On arrival to the operation theatre, Bispectral index electrode was applied on the patients forehead and
connected to the multiparameter monitor and BIS values monitored throughout. Inj. glycopyrrolate 0.2mg I.V., Inj. Fentanyl 1 mcg/kg I.V. was administered. Conclusion: Bispectral index is a simple, objective measure to assess depth of anaesthesia. There were predictable changes in BIS with the anesthesia technique in the present study. Similarly hemodynamic changes were also on the expected lines during the course of anesthesia.
