Design outcomes

Primary

MeasureTime frame
Laryngeal mask airway displacement during surgery, hemodynamic changes, rebreathing CO2 content, amount of anesthetic medication required in both groups (e.g., narcotics), time from the end of surgery to tube removal, and complications such as nausea and vomiting, dental trauma, oxygen saturation drop, airway spasm (tracheolaryngospasm), sore throat, and postoperative airway ulceration. Timepoint: Outcomes such as laryngeal mask airway displacement during surgery, hemodynamic changes, CO2 regurgitation, amount of medication required during anesthesia in both groups (e.g., narcotics), and time from the end of surgery to tube removal during anesthesia will be measured and recorded. Other outcomes such as nausea and vomiting, dental trauma, oxygen desaturation, airway spasm (tracheolaryngospasm), sore throat, and airway ulceration will be assessed after surgery. Method of measurement: A researcher-made checklist is used to collect patient information, which is designed according to the intended objectives. Both groups will be studied in terms of variables such as age, gender, Mallampati score, and BMI. Then, the intended objectives of the study will be compared in the two groups. We will use the anesthesiologist and his assistant to record the movement of the laryngeal mask airway during the procedure, and we will observe, record, and compare hemodynamic changes, CO2 return content, the amount of medication required during anesthesia in both groups (e.g., narcotics), the time from the end of the procedure to the removal of the tube, and complications such as nausea and vomiting, dental damage, oxygen saturation drop, airway spasm (tracheolaryngospasm), sore throat, and postoperative airway ulceration.
