Brief summary
different ways of airway management in elective minor surgeries of geriatric patients
Detailed description
The investigators will used two different ways of pro-seal laryngeal mask insertion technique (laryngoscopy- guided technique or the standard technique) in elective minor surgeries of geriatric toothless patients. The investigators will record the respiratory dynamics, heartbeat, systolic, diastolic, mean arterial pressures every 5 minutes during surgery. The investigators will record the laryngeal mask insertion time and oropharyngeal leakage pressure. The investigators will evaluate the placement of a laryngeal mask according to young criteria. The development and severity of coughing, retching, laryngospasm, extremity, and head movement during laryngeal mask placement will be recorded. Bloodstains, sore throat, hoarseness will be recorded on the mask that may develop due to laryngeal mask placement. The investigators will use the Briacombe scoring and Campbell category system to assess the position of laryngeal mask airway devices.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| laryngeal mask placement | First minute after laryngeal mask insertio | 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. |
| complications of laryngeal mask insertion | Complications will be evaluated within 1 hour after patient recovery. | complications like sore throat, hoarseness, nausea, and vomiting or Bloodstain on the laryngeal mask. we simply asked patients about them |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| respiratory dynamics | The first minute after the laryngeal mask insertion, and every 5 minutes thereafter up to the 20th minute | The investigator will record the (tidal volume(ml) value from the mechanical ventilator after wearing the laryngeal mask. |
| hemodynamic response | Before putting on the Layngeal mask, it will record in beats / minute at 5 minutes for 1 minute and 20 minutes after wearing | Heart rate will record before LMA and post LMA used at first minute |
| oxygen saturation | Before putting on the Layngeal mask, it will record in %SpO2 at 5 minutes for 1 minute and 20 minutes after wearing | saturation will record before LMA and post LMA used at first minute |
| hemodynamic responce | Before putting on the Layngeal mask, it will record in mm Hg at 5 minutes for 1 minute and 20 minutes after wearing | mean blood pressure will record before LMA and post LMA used at first minute |
| insertion time | 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. | 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 |
