Clinical Trial Summary

The purpose of this study is to determine whether preoperative administration of Modified Tian Wang Bu Xin Dan Hydrogel Patch prevents the incidence of postoperative delirium in elderly patients undergoing major surgery.

Description:

The Traditional Chinese Medicine (TCM) Tian Wang Bu Xin Dan (TWBXD, Cheonwangbosimdan), first recorded in Effective Formulae Handed Down for Generations ( Shi Yi De Xiao Fang) in 1337, is a herbal medicine that has been continuously utilized in Chinese medicine. It alleviates insomnia, anxiety, and palpitation by furnishing energy and stabilizing patients' mind. Cheonwangbosimdan can mitigate primary insomnia and secondary insomnia in patients with hyperthyroidism and menopause without severe side effects.

Tianwang Buxin Decoction has the same effect as Olanzapine for the treatment of delirium after hip joint replacement in falling-induced senile femoral neck fracture patients.

This study aim to evaluate the incidence of postoperative delirium in elderly patients treated with prophylactic Modified Cheonwangbosimdan Hydrogel Patch versus placebo patch.
