- Primary Outcome Measures
Name Time Method Primary aim: <br/ ><br>1) To compare endotracheal cuff pressures obtained by- manual inflation of pilot balloon (by a syringe) and direct inflation via a cuff pressure gauge. <br/ ><br>2) To evaluate changes in cuff pressure over time. <br/ ><br>Timepoint: 1. just after intubation <br/ ><br>2. at 30 mins <br/ ><br>3. at 1 hour <br/ ><br>4. at 2 hours <br/ ><br>5. at 3 hours <br/ ><br>6. at 4 hours/ just before extubation
- Secondary Outcome Measures
Name Time Method Secondary aim: <br/ ><br>To assess complications like sore throat, hoarseness of voice, cough, post extubation stridor which may occur as a result of overinflated ETT cuff; aspiration which may occur as a result of insufficiently inflated cuff. <br/ ><br>Timepoint: secondary outcome observed after 2 hours and 24 hours after extubation
