Clinical Study of Stellate Ganglion Block Combined with General Anesthesia on Hemodynamics, Cognitive Function, and Gastrointestinal Function in Elderly Patients Undergoing Partial Hepatectomy

Partial hepatectomy under general anesthesia is prone to hemodynamic alterations, and stress reactions are the main contributing factors to postoperative cognitive function in elderly partial hepatectomy patients. Postoperative cognitive dysfunction increases the incidence of postoperative complications and long-term morbidity and mortality in elderly patients. With the increasing trend of aging population and the gradual increase of elderly people undergoing surgical treatment, it is especially important to study the corresponding prevention and treatment measures. In this study, a total of 90 patients with primary liver cancer who received hepatectomy in our hospital from July 2020 to July 2021 were included as the research subject. The changes in hemorheology, stress-related indexes, cognitive function, postoperative pain, and gastrointestinal function were compared between the two groups The results showed that SGB combined with general anesthesia can effectively reduce hemodynamic fluctuations in elderly partial hepatectomy patients, alleviate surgical stress, promote postoperative recovery of cognitive function and gastrointestinal function with high safety, and is worthy of clinical promotion.
