Bispectral index analysis in general anesthesia: An observational study
Journal Title: Indian Journal of Clinical Anaesthesia - Year 2018, Vol 5, Issue 3
Abstract
Introduction Bispectral index monitoring BIS is one of the major techniques used in monitoring depth of anesthesia The present study was carried out to observe the changes in BIS values visavis the changes in hemodynamic parameters during the standard general anaesthesia practices in our instituteMaterials and Methods This prospective observational study was carried out in 50 ASA III elective surgeries in adults under general anesthesia Conditions and drugs likely to interfere with BIS values were excluded Anesthesia protocol was kept uniform Patients were induced with IV propofol 2mgkg IV pentazocine 05mg kg and IV vecuronium 01mgkg Patients were intubated with appropopriate size endotracheal tube and oxygen nitrous oxide halothane and vecuronium were used for maintanence of anesthesia Patients were reversed with IV neostigmine 005mgkg and I V Atropine 20mcgkg The BIS values hemodymanic changes recovery characteristics including awareness were noted Correlation between BIS scores and hemodynamic parameters was assessedResults There were predictable changes in BIS scores with the standard anesthesia technique followed in the present study Similarly hemodynamic changes were also on the expected lines during the course of anesthesia However the correlation between BIS score and hemodynamics could not be establishedConclusion Bispectral Index Monitor is a useful tool to assess the depth of anesthesia in standard anesthetic management Alterations in anesthetic management and drug dosages can be guided by BIS scores Cost factor and the need to use updated and refined versions of the software are the possible limitations Keywords Electroencephalography Consciousness monitors Anesthesia General Hemodynamics
