Effect of Laryngeal Mask Airway Storage Temperature on Postoperative Sore Throat
Investigation of the Effect on Postoperative Sore Throat of Insertion of Laryngeal Mask Airways Stored at Different Temperatures
NA · Ankara City Hospital Bilkent · NCT06713343
This study is testing whether the temperature at which laryngeal mask airways are stored affects the chances of patients getting a sore throat after surgery.

What this trial studies
This study investigates how the storage temperature of classical laryngeal mask airways (cLMAs) affects the incidence of postoperative sore throat in patients undergoing elective surgery. A total of 172 patients aged 18 to 65 will be randomly assigned to two groups: one group will receive cLMAs stored at low temperatures (10-12 °C) and the other at room temperatures (22-25 °C). Postoperative symptoms such as sore throat, dysphagia, dysphonia, and cough will be assessed at multiple time points after surgery. The study aims to provide insights into optimizing airway management during general anesthesia.
Who should consider this trial
Good fit: Ideal candidates for this study are adults aged 18 to 65 who are scheduled for elective surgery requiring general anesthesia with a duration of 1 to 2 hours.
Not a fit: Patients with significant comorbidities, those outside the age range, or those with recent sore throat issues may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could lead to improved postoperative comfort and reduced incidence of sore throat for patients undergoing general anesthesia.
How similar studies have performed: While the specific approach of varying storage temperatures for cLMAs is novel, similar studies have explored factors affecting postoperative outcomes with varying degrees of success.
