About
Postoperative sleep disorder is one of the common complications after general anesthesia. Compared to patients of various ages, elderly patients have a much higher incidence of postoperative sleep disturbance. Postoperative sleep disorders can have many adverse effects, including cognitive impairment, altered pain perception, and emotional disorders, which are not conducive to the long-term prognosis of elderly patients. Enhancing postoperative sleep quality in older patients has become a significant public health concern in the current day due to its direct relationship to both maximizing surgical outcomes and enhancing physical health. This study intends to conduct a prospective, randomized controlled, triple-blind clinical trial on use of transauricular vagal nerve stimulation to improve sleep disorders in elderly patients after general anesthesia surgery, aiming to investigate the efficacy of transauricular vagal nerve stimulation in postoperative sleep disorders in elderly patients.
