Primary outcomePrimary: The Best Glottic View Obtained During Laryngoscopy — 186; 228; 163; 151 participants — p=>0.05
Summary
Our hypothesis is that the view of the glottis may be improved by putting all patients requiring intubation in the ramped or back up position while maintaining the classic sniffing position.

Eligibility Criteria
Inclusion Criteria
- Adult surgical patients who required intubation as part of their routine anaesthesia
Exclusion Criteria
- Patients less than 18 years old,
- Patients recognised to have difficult airways where an alternative method of intubation (e.g. fibre optic) was the method of choice,
- Patients undergoing emergency surgery where patient positioning and data collection might cause delay (e.g. exsanguinating patients) or where the supine position is not optimal (e.g. brisk bleeding into the upper airway),
- Patients requiring rapid sequence induction of anaesthesia
