| Type | Measure | Description | Time frame | Safety issue |
|---|---|---|---|---|
| Primary | laryngeal mask placement | To evaluate the best fiberoptic bronchoscopic view while insertion of pro-Seal laryngeal mask either in a classic way, or with the help of laryngoscope. The fibreoptic evaluation Includes 4, only vocal cords visible; 3, vocal cords plus posterior epiglottis visible 2, vocal cords plus anterior epiglottis visible
; 1, vocal cords not seen. |
First minute after laryngeal mask insertio | |
| Primary | complications of laryngeal mask insertion | complications like sore throat, hoarseness, nausea, and vomiting or Bloodstain on the laryngeal mask.
we simply asked patients about them |
Complications will be evaluated within 1 hour after patient recovery. | |
| Secondary | hemodynamic response | Heart rate will record before LMA and post LMA used at first minute | Before putting on the Layngeal mask, it will record in beats / minute at 5 minutes for 1 minute and 20 minutes after wearing | |
| Secondary | insertion time | Insertion time was defined from the time of removal of the facemask to the time of the appearance of first capnography upstroke. we assessed this outcome stopwatch | The investigator will record the insertion time in seconds from the moment the laryngeal mask airway passes the incisors until the end-tidal CO2 is visible. | |
| Secondary | respiratory dynamics | The investigator will record the (tidal volume(ml) value from the mechanical ventilator after wearing the laryngeal mask. | The first minute after the laryngeal mask insertion, and every 5 minutes thereafter up to the 20th minute | |
| Secondary | hemodynamic responce | mean blood pressure will record before LMA and post LMA used at first minute | Before putting on the Layngeal mask, it will record in mm Hg at 5 minutes for 1 minute and 20 minutes after wearing | |
| Secondary | oxygen saturation | saturation will record before LMA and post LMA used at first minute | Before putting on the Layngeal mask, it will record in %SpO2 at 5 minutes for 1 minute and 20 minutes after wearing | |
| Secondary | respiratory dynamics | The investigator will record the peak airway pressure (cmH2O) value from the mechanical ventilator after wearing the laryngeal mask. | The first minute after the laryngeal mask insertion, and every 5 minutes thereafter up to the 20th minute | |
| Secondary | respiratory dynamics | The investigator will record the end-tidal CO2(mmHg) value from the mechanical ventilator after wearing the laryngeal mask. | The first minute after the laryngeal mask insertion, and every 5 minutes thereafter up to the 20th minute |
