Abstract:【Objective】 To investigate the therapeutic effect of modified Zhenwu Decoction in patients undergoing shoulder arthroscopy during the perioperative period. 【Methods】 A total of 80 patients who underwent shoulder arthroscopy in our hospital from January 2023 to December 2024 were selected and divided into a control group and an observation group according to different perioperative management methods, with 40 cases in each group. The control group received routine perioperative management and standard thermal insulation, while the observation group was additionally treated with modified Zhenwu Decoction on the basis of the control group. Body temperature indicators [incidence of hypothermia, minimum core body temperature, Bedside Shivering Assessment Scale (BSAS) score], recovery indicators [awakening time, length of stay in Post-Anesthesia Care Unit (PACU)] and postoperative complications were compared between the two groups. 【Results】 The incidence of hypothermia and BSAS score in the observation group were lower than those in the control group (P<0.05), and the minimum core body temperature was higher than that in the control group (P<0.05). The postoperative awakening time and PACU stay in the observation group were shorter than those in the control group (P<0.05). There was no statistically significant difference in the total incidence of postoperative complications between the two groups (P>0.05). 【Conclusion】 The combination of modified Zhenwu Decoction and standard thermal insulation in the perioperative period of shoulder arthroscopy can reduce the risk of perioperative hypothermia, alleviate shivering, promote early recovery of patients, and shows favorable safety.
