Abstract: AIM -In this study we will evaluate the effect of Bispectral index monitoring as compared to haemodynamic monitoring in patients undergoing one lung ventilation during thoracic surgery. STUDY DESIGN Prospective single blinded study METHODS - 30 adult patients of age group 20-65 years scheduled for thoracotomy were divided into two groups of 15 each. Patients in group 1 (Haemodynamic group) anaesthesia was maintained with 100 % oxygen and isoflurane based upon haemodynamic variables. The anaesthesiologist was blinded to BIS values in group 1. Patients in group 2 (BIS group) anaesthesia was maintained with 100 % oxygen and isoflurane and a BIS of 40-60 was maintained. In group 2 BIS monitoring was continuously available to the anaesthesiologist. Bispectral index values between the groups and within the group compared. Haemodynamic variability, MAC values, end-tidal isoflurane concentration, Eye opening time and extubation time and amount of isoflurane were compared between both groups. RESULTS - BIS values are high during one lung ventilation with 100 % oxygen in haemodynamic as compared to BIS group. Haemodynamic variability, eye opening time, tracheal extubation time, MAC values, End-tidal isoflurane concentration, and amount of isoflurane was less in BIS group as compared to haemodynamic group.
