Background: Perfusion index (PI) is a reliable and accurate indicator to conventional hemodynamic criteria for recognition of stress response to insertion of endotracheal intubation during Propofol, Fentanyl and Isourane anaesthesia among adult patients. However, there is scarce literature indicating its relation with Sevourane. The current study was executed to examine the changes in PI as an indicator of pressor response after ETT and laryngoscopy supplemented with Sevourane. Methodology:Asingle prospective randomized comparative controlled trial was carried out at one of the public medical schools in Maharashtra. Atotal 60 patients were distributed into two groups namely Group S (study group) - patients mask ventilated with 100% Oxygen and 1% Sevourane and Group C (control group) - patients mask ventilated with 100% Oxygen only. Results: The perfusion index following pre-medication did not change signicantly. No signicant change was detected after pre-oxygenation. After induction, there was a rise in PI after Propofol administration whereas after mask ventilation, it remained stable in group C but in group S it was improved after giving Sevourane. Conclusion: During mask ventilation, 1% Sevourane is effective in controlling the perfusion index after laryngoscopy and endotracheal intubation.
