The Effect of Softening of Endotracheal Tubes on the Decrement of Postoperative Hoarseness and Sore Throat.

Background: Hoarseness, cough, and sore throat are the most prevalent complications after removing patients' endotracheal tube and general anesthesia. Various methods have been proposed to reduce these complications after intubation.

Objectives: The present study aimed to assess the effect of softening the endotracheal tube with normal warm saline on reducing post-intubation complications such as sore throat and hoarseness.
