Different dexamethasone doses in the perioperative period improve short-term outcomes of total hip arthroplasty: a randomized controlled trial.

Dexamethasone provides short-term advantages in reducing pain, PONV, inflammation, and ICFS, and increasing ROM in the early postoperative period after THA. Dexamethasone efficacy in reducing post-THA pain, inflammation, and PONV at 10 mg and 15 mg is similar during the first 48 h. Dexamethasone (30 mg) divided into three 10 mg doses was superior to two doses (15 mg) in reducing pain, inflammation, and ICFS, as well as in increasing ROM on postoperative day 3.
