Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Duration of insertionTimepoint: Time from picking up the device to first successful breath made by manual ventilation | — |
Secondary
| Measure | Time frame |
|---|---|
| Hemodynamic effectsTimepoint: Pulse Rate , Blood Pressure (systolic , diastolic & mean) , Oxygen saturation are monitored and recorded.;Leak volumesTimepoint: The difference between inspired tidal volume (ITV) and expired tidal volume (ETV);Number of insertion attemptsTimepoint: A failed attempt is defined as removal of the device from the mouth before re-insertion.;Perioperative ComplicationsTimepoint: Bronchospasm ,Laryngospasm and coughing , trauma , postoperative sore throat (constant pain, independent of swallowing), dysphagia (difficulty or pain with swallowing), dysphonia (difficulty or pain with speaking);Reposition attemptsTimepoint: Manipulations allowed: gentle pushing or pulling of the device, chin lift, jaw thrust, head extension, or neck flexion.;Sealing pressure (airway leak pressure)Timepoint: Measuring the minimal airway pressure at which an audible gas leak occurred using a stethoscope placed just lateral to thyroid cartilage. | — |
