Single High-Dose Systemic Methylprednisolone Administered Preoperatively Improves Pain Control and Sleep Quality After Total Hip Arthroplasty: A Double-Blind, Randomized Controlled Trial

BACKGROUND: This study was performed to evaluate the efficacy of preoperative high-dose methylprednisolone on pain levels and sleep quality following primary total hip arthroplasty. MATERIAL AND METHODS: A double-blind, randomized controlled trial was performed in adults underdoing total hip arthroplasty. A computer-generated, permuted-block randomization scheme with a 1:1 ratio between the intervention (125 mg methylprednisolone) and control groups (normal saline) was utilized. Patients underwent a similar preoperative and postoperative protocol. Pain was assessed using the visual analog scale (VAS). Sleep quality was assessed at the 2-week postoperative visit using the Pittsburgh Sleep Quality Index (PSQI). RESULTS: With a total of 70 patients, 35 patients were included in the intervention and placebo groups. Hospital stay was significantly shorter in the intervention group (1.5 ± 0.7 vs 2.0 ± 0.5 days, P = .03). Preoperative pain levels were similar between groups, while satisfactory pain control was achieved in a significantly larger number of patients in the intervention group (18 vs 8 patients, P = .009). The intervention group was significantly more likely to have a good sleep quality than the placebo groups (74% vs 31%, P = .001). No significant differences were found between preoperative and postoperative blood sugar levels. We did not observe any cases of early postoperative wound complication, infection, or deep vein thrombosis among our patients. CONCLUSION: In this randomized controlled trial, preoperative administration of 125 mg of methylprednisolone was found to improve pain control, as measured by VAS, 24 hours after surgery, and sleep quality, as measured by PSQI, 2 weeks following surgery.
