BACKGROUND

Intertrochanteric fracture in the geriatric population is associated with poor prognosis, which may be attributed to consistent stress and the systemic inflammatory response. Dexamethasone is an exogenous glucocorticoid commonly used in clinical practice for broad anti-inflammatory action. The purpose is to investigate whether a single preoperative low-dose dexamethasone can improve the in-hospital prognosis in geriatric intertrochanteric fracture patients undergoing internal fixation surgery.

METHODS

Between June 2020 and October 2022, 219 eligible patients with intertrochanteric fractures were in this study. After meeting the inclusion and exclusion criteria, 160 patients were randomly allocated to the dexamethasone or placebo groups (80 patients who are geriatric with an intertrochanteric fracture in each group). The patients in the dexamethasone group received 10 mg (2 mL) of dexamethasone intravenously, whereas the patients in the placebo group received 2 mL of saline intravenously within 30 minutes before being sent to the operating room. The efficacy-related outcomes (the first bed-chair transfer ability, in-hospital mortality, and length of stay) and safety-related outcomes (infection events and hyperglycemia) were collected for analysis.

RESULTS

There were no significant differences in the baseline characteristics between the 2 groups. The dexamethasone group had a significantly higher rate of the first bed-chair transfer than the placebo group (65.0% [52/80] vs 48.8% [39/80], relative risk = 1.46, 95% confidence interval = 1.02 to 2.11; P = .038). One patient in the dexamethasone group and 7 patients in the placebo group died during hospitalization (1.3% [1/80] vs 8.8% [7/80], relative risk = 0.92, 95% confidence interval = 0.86 to 0.99; P = .07). No differences were found in the length of stay, infections, and hyperglycemia between the 2 groups.

CONCLUSION

A single preoperative low-dose of dexamethasone can improve the in-hospital prognosis (increase the ability of the first bed-chair transfer and potentially decrease the in-hospital mortality) in geriatric intertrochanteric fracture patients after internal fixation surgery.
