Background and Aims: I gel has become one of the popular choice to provide anaesthesia using intravenous propofol as induction agent. This study aims to compare the dose of propofol required for induction and insertion of I gel using Bispectral index monitor as a guide. Materials and Methods: A randomised prospective study was conducted in 60 patients of ASA grade I-II of either sex aged 20-50 years who underwent elective surgery under general anaesthesia using I gel device. The patients were randomly divided in to two groups. Group A received BIS guided propofol to achieve target value of 50 and Group B received propofol till loss of eyelash reflex and jaw relaxation. The total dose of propofol and ease of insertion was compared between the groups. The statistical analysis was done using unpaired t test, chi square test and student t test. A p value of <0.05 was considered significant.Results: The demographic characteristics were comparable in both groups. The mean induction dose of propofol required in Group A and Group B was 84.66 ± 5.56 mg 97.33 ±10.48 mg respectively which was statistically significant ( p <0.000). The ease of insertion and hemodynamic parameters were was comparable in both groups. Conclusion: Induction dose of propofol required for I gel insertion by using BIS value as a guide reduces the overall dose without affecting the appropriate conditions required for I gel insertion.
