Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The anesthesiologist will administer the intervention which will approximately last about 20-60 seconds. After induction and insertion of pro-Seal laryngeal mask either in a classic way, with a laryngoscope or with the help of video laryngoscope volume-controlled ventilation mode will be set. We will record the respiratory dynamics, heartbeat, systolic, diastolic, mean arterial pressures every 5 minutes during surgery. We will record the laryngeal mask insertion time and oropharyngeal leakage pressure. We 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. We will use the Briacombe scoring system to assess the position of laryngeal mask airway devices.

Outcomes
Primary outcome [1] 321594 0
To evaluate the best fiberoptic bronchoscopic view while insertion of pro-Seal laryngeal mask either in a classic way, with a laryngoscope or with the help of a video 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.
Timepoint [1] 321594 0
if we insert the laryngeal mask for the first time with no resistance, only with jaw opening movement, we call it an easy insertion. If slight resistance occurred while insertion, we call it Moderately difficult placement . if we insert it at second or third time, we exclude these patients.
Secondary outcome [1] 375504 0
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,
Timepoint [1] 375504 0
we will record the time of insertion from the time laryngeal mask airway passes the incisor teeth until we see end-tidal CO2.
Secondary outcome [2] 375506 0
We will record: - complications like sore throat, hoarseness, nausea, and vomiting we simply asked patients about them

half an hour after surgery
Secondary outcome [3] 377644 0
Following electrocardiography, we will record the heartbeat.

We will record the respiratory dynamics (tidal volume, peak airway pressure, end-tidal CO2) from the mechanical ventilator,

Secondary outcome [8] 381910 0
We will record the mean arterial pressures. By monitoring non-invasive blood pressure.
Timepoint [8] 381910 0
Every 5 minutes during surgery.
Secondary outcome [9] 381911 0
We will record the oxygen saturation. With pulse oximeter evaluation.
