Health authority | |
Study type | Interventional |
Patients undergoing video-assisted thoracoscopic surgery requiring double-lumen tube intubation are randomized into two groups; gum group and control group. In the gum group, patients are instructed to chew gum for 2 minutes, approximately 10 minutes before induction of anesthesia. Patients in the control group are instructed to swallow saliva twice. Postoperative sore throat and hoarseness are assessed 30 minutes after recovery room admission, and at 2 and 24 hours after extubation.
