Airway Morbidity
Conditions
Brief summary
The LMA ProtectorTM is a new extraglottic airway device which brings together features of both the LMA ProSealTM (high seal cuff, gastric access and bite block - to facilitate ventilation, airway protection and airway obstruction, respectively) and the LMA UniqueTM (single use - prevention of disease transmission). In the following randomized study the investigators test the hypothesis that ease of insertion, oropharyngeal leak pressure, fiberoptic position and ease of gastric tube placement differ between the LMA ProtectorTM and the Ambu AuraGainTM in paralyzed, anesthetized patients.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| oropharyngeal leak pressure | 5 min | Oropharyngeal leak pressure was determined by closing the expiratory valve of the anesthesia breathing system and a fixed gas flow of 3 l minute-1. The airway pressure at which an equilibrium was reached was noted (maximum allowed 40 cm H2O). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| anatomic position | 5 min | The anatomic position was assessed by passing a fiberoptic scope through the airway tube stopping 0,5 cm prior to the end of the tube. The airway tube view was scored using an established scoring system. |
