To find out the relation of carbon dioxide (CO2) levels in the lungs while awakening from anesthesia and return of consiousness using the monitoring with concentration of anesthetic gases in the lungs.

Design outcomes

Primary

MeasureTime frame
Changes in EtCO2 and its relation with emergence from anaesthesia and return of consciousness.Timepoint: Baseline ABG will be done after induction and 2nd ABG will be done before giving reversal. After giving reversal the following parameters will be recorded every minute - vitals, SpO2, RR, tidal volume and for every 30 seconds EtCO2, MAC, BIS and TOF will be noted.—

Secondary

MeasureTime frame
To find out the correlation of ETCO2 with adequacy of neuromuscular blockade reversal and emergence as measured with MAC, BIS.Timepoint: Baseline ABG will be done after induction and 2nd ABG will be done before giving reversal. After giving reversal the following parameters will be recorded every minute - vitals, SpO2, RR, tidal volume and for every 30 seconds EtCO2, MAC, BIS and TOF will be noted.—
