An observational study in Laparoscopic Surgery, Tracheal Intubation Morbidity and Sore-throat, sponsored by Seoul National University Hospital. Completed at 2 sites in South Korea. Open to participants aged 19 Years and older. Per ClinicalTrials.gov, last updated 2026-01-12.
Sponsored by Seoul National University Hospital · Observational
The main objective of this study is to evaluate the association between the duration of intraoperative cuff overpressure and the development of postoperative sore throat.
For patients undergoing laparoscopic surgery after tracheal intubation, continuous cuff pressure monitoring is performed by connecting a pressure monitor to the cuff of the endotracheal tube. The incidence of postoperative sore throat was evaluated via direct questioning in all patients. This study aimed to investigate the association between the development of postoperative sore throat and the duration of overpressure in the cuff of the endotracheal tube.
