Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Duration of reaching to the Bispectral Index between 60 to 70. Timepoint: from the start point of induction untill reaching to the Bispectral Index between 60 to 70. Method of measurement: using the bispectral index monitor based on electroencephalogram waves during anesthesia, measuring time in seconds.;Duration till the loss of response to squeezing the trapezius muscle. Timepoint: from the start point of induction to complete loss of response to squeezing the trapezius muscle. Method of measurement: measuring time in seconds, by physical examination and observing patient's reaction.;Duration until Laryngeal Mask Airway installation. Timepoint: from the start point of induction until Laryngeal Mask Airway installation. Method of measurement: measuring time in seconds.;Existence of reaction to Laryngeal Mask Airway installation. Timepoint: During Laryngeal Mask Airway insertion. Method of measurement: Observing the patient's reaction.;Heart rate. Timepoint: Immediately before induction and one minute after induction and during operation of the Laryngeal Mask Airway. Method of measurement: Beat Per minute using a non-invasive heart rate monitor.;Blood pressure. Timepoint: Immediately before induction and one minute after induction and during operation of the Laryngeal Mask Airway. Method of measurement: In millimeters of mercury using a non-invasive method of measuring blood pressure by monitoring device.;Oxygen saturation. Timepoint: Immediately before induction and one minute after induction and during operation of the Laryngeal Mask Airway. Method of measurement: in percent, by pulse oximeter device. | — |
