Primary Outcome Measures

Name	Time	Method
Sevoflurane consumptionTimepoint: One point measurement immediately after the extubation of the patient (using the ventilator display panel).

Secondary Outcome Measures

Name	Time	Method
Consumption of the fresh gas flow (Oxygen and air)Timepoint: One point measurement after the extubation of the patient (on the ventilator display panel).;Haemodynamic parameters (pulse, mean arterial pressure)Timepoint: Once every 5 minutes after the start of anaesthesia till the extubation of the patient.;Time taken to achieve target Minimum alveolar concentrationTimepoint: Time of initiation of Sevoflurane is noted. <br/ ><br>Time to reach target Minimum alveolar concentration is noted. Time difference is calculated and noted.;Time taken to extubationTimepoint: Time of discontinuing Sevoflurane is noted. Time of extubation is noted. Time difference is calculated and noted.;Total IV Atracurium usedTimepoint: One point measurement after discontinuing IV Atracurium infusion.;Total IV Fentanyl usedTimepoint: One point measurement after discontinuing IV Fentanyl infusion.
