Pain | Prospective, Randomized, Double Blind Study Comparing IV vs PO Acetaminophen in Patients Undergoing Lumbar Discectomy

Pain research study

What is the primary objective of this study?

Both intravenous and oral acetaminophen have been shown to reduce post-operative pain scores when given preoperatively. This study investigates if there is a difference between the intravenous and the oral forms when given preoperatively to patients undergoing lumbar microdiscectomy. We hypothesize that the intravenous formulation does not improve pain scores or decrease opioid consumption during the first postoperative day compared to the oral formulation.

Who is eligible to participate?

Inclusion Criteria: - Single level lumbar micro disk surgery - Ages 18-65 Exclusion Criteria - morbid obesity - prior back surgery - opioid tolerance - pregnancy

Which medical condition, disease, disorder, syndrome, illness, or injury is researched?


Study Interventions
