Early Oral Hydration After Thoracoscopic Surgery
The goal of this clinical trial is to learn about the safety and feasibility of early oral hydration in patients receiving video-assisted thoracoscopic surgery after general anesthesia. The main questions aims to answer:

the safety and feasibility of oral hydration supplementation in the recovery room following general anesthesia.
the degree of improvement in sore throat and dry mouth after oral hydration.
the side effects and risks of oral hydration supplementation, such as the incidence of postoperative nausea and vomiting.
the impact of oral hydration supplementation in the recovery room following general anesthesia on hemodynamics.
patient satisfaction with oral hydration supplementation in the recovery room following general anesthesia.

Participants will receive a series of oral hydration from swab moistening, and ice cube hydration to water hydration in the recovery room. Researchers will compare with the standard, no-hydration group to see if it is safe and feasible to hydrate patients in the recovery room.
