This research study is a prospective, randomized, blinded, placebo controlled trial evaluating the benefit of IV acetaminophen (Ofirmev™) as adjuvant analgesia in geriatric hip fracture patients. IV acetaminophen has received FDA approval. IV acetaminophen does not have the liver toxicity as oral acetaminophen. No oral acetaminophen will be administered. All patients diagnosed with a hip fracture aged at least 65 years and expected to undergo surgical intervention are eligible to participate. Hip fractures affect greater than 300,000 geriatric patients annually, representing the second leading cause of hospitalization for this patient population. Pain control in these patients is often problematic due to co-morbidities and changes in their pharmacokinetic and pharmacodynamic profiles. Subjects may receive the normal DVT prophylactic treatments post-op.
