Effects of Multiple Intravenous Doses of Perioperative Vitamin C on Pain Management Following Total Hip Arthroplasty

In the vitamin C group, the subcutaneous morphine injection dosage was considerably lower (0-24h 6.1mg ± 2.7mg vs 4.0mg ± 2.9mg, p = 0.000, total use 8.3mg ± 3.1mg vs 6.6mg ± 3.9mg, p = 0.018). During the perioperative term, the vitamin C group experienced better hip motion and lower VAS pain levels at rest and during exercise.
