|---|---|
| Incidence of gastric insufflation with and without an inserted gastric tube during incremental peak airway pressure trial (PAP)in thermoelastic cuff supraglottic devices.Timepoint: 1. Pre operatively (baseline) 2. Before start of first incremental positive airway pressure trial (approximately 8-10 mins after entering the operation theatre) 3. After completion of first incremental positive airway pressure trial 4. Before start of second incremental positive airway pressure trial 5. After completion of second incremental positive airway pressure trial | — |
