Abstract:[Objective] To investigate the efficacy and safety of dexamethasone used in perioperative period of femoral intertrochanter-ic fractures in elderly. [Methods] A total of 105 patients who underwent surgical treatments for femoral intertrochanteric fracture in our hos-pital from July 2021 to July 2023 were included and randomly divided into blank group, single-dose group and multiple-dose group by ran-dom number table method, with 35 cases in each group. The patients were given corresponding dexamethasone treatment in each group.The clinical and test data of the three groups were compared. [Results] All patients in the three groups had operation performed successful-ly. The multiple-dose group proved significantly superior to the blank group and single-dose group in terms of consumption of Tramadol[(60.4±13.2) mg vs (90.3±20.3) mg vs (75.4±17.6) mg, P<0.001] and metoclopramide [(7.7±3.8) mg vs (13.1±5.1) mg vs (10.5±3.1) mg, P<0.001]. The incidence of perioperative nausea and vomiting was ranked as the multipl-dose group < single-dose group < blank group [cases(%), 3 (8.6) vs 7 (20.0) vs 10 (28.6), P<0.001]. The ICFS, PSQI and VAS in the three groups were significantly decreased 1 and 3 days aftersurgery compared with those preoperatively (P<0.05). The multiple-dose group was significantly better than the blank group and singledosegroup regarding PSQI score and VAS score (P<0.05). In term of blood test, there were no statistically significant differences in WBC,CRP and IL-6 among the three groups before surgery (P>0.05). However, the multiple-dose group and single-dose group proved significnt-ly superior to the blank group in WBC [(9.7±2.6)×109/L vs (10.5±2.4)×109/L vs (12.8±3.2)×109/L, P<0.001], CRP [(19.2±6.9) mg/L vs (27.6±8.7) mg/L vs (39.4±10.2) mg/L, P<0.001] and IL-6 [(32.6±9.6) pg/ml vs (42.8±9.7) pg/ml vs (64.7±11.4) pg/ml, P<0.001] 3 days postopera-tively. [Conclusion] Multiple administrations of low-dose dexamethasone during perioperative period of femoral intertrochanteric fracturesnot only reduce pain, improve sleep and relieve perioperative fatigue, but also does not increase the risk of hormone-related complications.
