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.
