Design outcomes
Primary
| Measure | Time frame |
|---|---|
| To compare oropharyngeal leak pressure of Ambu AuraGain, Blockbuster and Protector laryngeal mask airway in paralysed anaesthetised patientsTimepoint: To compare oropharyngeal leak pressure of Ambu AuraGain, Blockbuster and Protector laryngeal mask airway immediately and 5 minutes after successful insertion of the device which will be determined by presence of normal thoracoabdominal movement and a square wave capnograph on monitor while ventilating the patients. | — |
Secondary
| Measure | Time frame |
|---|---|
| Any other complications- device displacement, soft tissue oedema , dental trauma, blood stain on study deviceTimepoint: Device displacement, soft tissue oedema, dental trauma after successful insertion of the device & during the surgical procedure. Blood stain on study device immediately after removal of the device.;Complications such as sore throat, stridor or hoarsenessTimepoint: Complications such as sore throat, stridor or hoarseness after removing the device & shifting the patient in recovery room.;To compare fibreoptic assessment of glottic view through the deviceTimepoint: Fibreoptic assessment of glottic view through the device after successful insertion which will be determined by normal thoracoabdominal movements & a square wave capnograph on monitor while ventilating the patients.;To compare first attempt success rate of the device Timepoint: First attempt successful placement of the device will be identified just after insertion of the device by presence of normal thoracoabdominal movements & a square wave capnograph on monitor while ventilating the patients.;To compare hemodynamic parametersTimepoint: To compare hemodynamic parameters preoperatively,just before insertion, immediately after insertion, 1 minute, 5 minutes & 10 minutes after insertion of the device.;To compare insertion time of deviceTimepoint: Time taken for insertion of the device started with removal of face mask & ended with normal thoracoabdominal movements & square wave capnograph on monitor while ventilating the patients.;To compare number of insertion attempts of the deviceTimepoint: Number of attempts for successful device insertion will be determined just after insertion of device by the presence of normal thoracoabdominal movement & a square wave capnograph on monitor while ventilating the patients. | — |
