| Scientific title | |
| Study objectives | The rate of successful insertion during routine clinical anaesthesia is the primary outcome measure for comparison between the two supraglottic airway devices. 'Successful insertion' is defined as the provision of both an unobstructed, patient airway as judged clinically and by the measurement of satisfactory leak pressure. Pressure is needed to ventilate the lungs. Above a certain normal pressure, there is an audible leak of gas from between the patient's larynx and the airway management device. This leak pressure is recorded routinely all anaesthetics. The better the seal of a device at the patient's larynx, the higher the leak pressure. |

| Intervention | 1. Selection of research participants 2. Explanation of research proposal and procedure, including provision of written information sheet and sufficient time for questions 3. Written consent 4. Randomisation to receive either i-gel airway (I-gel group) or LMAu (LMA group) 5. Induction and maintenance of anesthesia in a standard manner 6. Insertion of selected airway device, examining study objectives (as above) 7. After successful insertion, it will be left in place for the maintenance of anaesthesia 8. After the end of the operation the patient will regain consciousness and the device will be removed 9. Routine assessment will be made of sore throat etc, as is normal practice |
