What this trial studies

This project aims to compare the effects of three types of laryngeal masks—BlockBuster, i-gel, and GMA-TULIP—on postoperative throat pain and patient comfort during laparoscopic surgeries performed in the Trendelenburg position under general anesthesia. The study will involve patients aged 18 to 80 who are undergoing surgeries lasting less than three hours and meet specific health criteria. By evaluating the incidence of sore throat and overall satisfaction, the research seeks to identify the most effective airway management method for enhancing patient outcomes.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 to 80 with a body mass index under 28, undergoing laparoscopic surgeries in the Trendelenburg position.

Not a fit: Patients with difficult airways, laryngopharyngeal diseases, or those unable to cooperate with the study will not benefit from this research.

Why it matters

Potential benefit: If successful, this study could lead to improved postoperative comfort and reduced throat pain for patients undergoing laparoscopic surgeries.

How similar studies have performed: Previous studies have indicated varying success with different laryngeal masks, but this specific comparison is relatively novel.
