Post-Operative Pain, Chronic
Conditions
Brief summary
This study is a randomized study that compares two commonly used post-operative pain reducing techniques by measuring the level of pain and use of pain medication after knee surgery.
Detailed description
Post-operative pain is a commonly associated with knee surgery. Treatment often includes an oral or intravenous (IV) narcotic regimen which often leads to nausea, vomiting and can cause consti-pation. These issues can contribute to the overall discomfort of the post-operative patient. Intra-operative injections and local nerve blocks have become common adjuncts to narcotics to reduce post-operative pain and the necessity for oral or IV narcotic use. The aim of this study is to com-pare analgesic use and clinical effects on post-operative pain management with intra-articular in-jection of 20ccs of 2% lidocaine with epinephrine at the start of the case plus 20ccs 0.5% mar-caine with epinephrine at the end of the case vs. adductor canal saphenous nerve blockade in pa-tients undergoing knee arthroscopy, as indicated by the need for rescue narcotics and patient pain scores. A randomized, single blinded study will be performed to evaluate post-operative pain control using VAS scores at 1, 2, 4, 8, 12, 24, 36, and 48hrs post-operatively, rescue narcotic use in the PACU, and total narcotic consumption over the same time period.
Interventions
DRUGAdductor Canal Block
The anesthesia provider will identify the adductor canal using ultrasound guidance and inject 15ccs of 0.5% marcaine with epinephrine around the saphenous nerve.
receive 20ccs of 2% lidocaine with epinephrine as an intra-articular injection
