Effect of Cuff Pressure of Endotracheal Tube on POST

Effect of Cuff Pressure of Endotracheal Tube on Postoperative Sore Throat: a Prospective Observational Study

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.

Inclusion Criteria:

- Patients undergoing laparoscopic surgery and endotracheal intubation under general anesthesia

Exclusion Criteria:

• Patients who already had sore throat and hoarseness before surgery
• Patients who were expected to have anticipated difficult airway
• Surgery duration < 1 hour
