Eligibility

Inclusion criteria

Inclusion criteria: ASA STATUS 1, 2, 3 ELECTIVE SURGERY IN THE SUPINE POSITION UNDER GENERAL ANAESTHESIA REQUIRING ORAL ENDOTRACHEAL INTUBATION

Exclusion criteria

Exclusion criteria: Difficult airway both anticipated and unanticipated. Multiple attempts of endotracheal intubation (two or more attempts). History of sore throat. Known anatomical laryngotracheal abnormalities. Surgeries in which nitrous oxide will not used or nitrous oxide discontinued intraoperatively. Patient in whom on table extubation is not done.

Design outcomes

Primary

MeasureTime frame
. To quantify the amount of air required to inflate the cuff to achieve intracuff pressure of 25 cmH2O under standard conditionsTimepoint: After endotracheal intubation and every hourly during intraoperative period

Secondary

MeasureTime frame
1. To observe the anatomical changes in the trachea before and after endotracheal cuff inflation. 2. Serial monitoring of ETT intracuff pressure every hourly and to find out any variations in the intracuff pressure during intraoperative period. 3. To see the incidence of postoperative sore throat. 4. To find out whether duration of surgery affects the incidence of post operative sore throat. Timepoint: during intraoperaive period tracheal diametres and cuff pressures will be measured and monitored in postopertaive sore throat will be assessed in post operative period
