Effect of Suanzaoren on Perioperative Analgesia, Hemodynamics and Postoperative Delirium

Abstract

Hip fracture is not only accompanied by severe pain, but also impair body tissue and organ functions in patients, particularly in elderly individuals who have reduced tolerance and are prone to organ damage after experiencing a hip fracture. Surgery is the primary clinical approach for treating hip fractures. However, both the fracture trauma and surgical procedure can result in significant pain during the perioperative period, leading to abnormal hemodynamic fluctuations and an increased risk of postoperative delirium. Therefore, it is crucial to select an appropriate intervention method to facilitate the postoperative rehabilitation of hip fracture patients. Traditional Chinese Medicine (TCM) acknowledges that surgery will have different degrees of impact on muscles and bones, Qi and blood. Suanzaoren Decoction contains suanzaoren, anemarrhena asphodeloides, ligusticum chuanxiong and other TCM. The effective components of these TCM, such as spinosin, sarsasapogenin, and tetramethylpyrazine, have been proved to have analgesic effects. This study demonstrates, through clinical trials, that Suanzaoren Decoction exerts a positive influence on promoting the postoperative rehabilitation of hip fracture patients by reducing postoperative pain, stabilizing hemodynamic indexes, improving inflammatory state, and shortening the duration of postoperative delirium (all P <0.05). The fact that Suanzaoren Decoction can effectively promote the postoperative rehabilitation of hip fracture patients may be related to the anti-inflammatory, analgesic and neuroprotective effects of the effective ingredients in the prescription, such as spinosin, sarsasapogenin and tetramethylpyrazine. Therefore, this study believes that Suanzaoren Decoction+ERAS intervention program represents an optimal approach for hip fracture surgery patients within the perioperative period.
