Randomized Controlled Trial
Adductor Canal Blocks with Bupivacaine and Magnesium After Same-day Discharge Total Knee Arthroplasty Improve Post-operative Pain Relief and Decrease Opioid Consumption: A Prospective Randomized Controlled Trial.
Adequate pain management is a critical component of facilitating same-day discharge for total knee arthroplasty (TKA). Adductor canal blocks (ACB) have been shown to be an effective technique for managing pain after TKA. The objective of this study was to investigate the impact of adding magnesium to local anesthetic in ACB on postoperative pain, opioid consumption, nausea, and overall patient satisfaction. ⋯ The addition of magnesium to local anesthetic in ACB decreases pain scores and opioid consumption, without increasing nausea, when compared with ACB with local anesthetic alone.

OxyContin was reformulated with a polyethylene oxide matrix in August 2010 to reduce the potential for intravenous abuse and for abuse by insufflation. The objective of this study was to evaluate the impact of OxyContin's reformulation on overdose (OD) risk for individuals dispensed OxyContin in comparison to those dispensed other opioids under regular care. ⋯ This study did not detect an overall effect of the OxyContin reformulation on OD in insured patients under regular medical care. There is a suggestion of a modestly reduced OxyContin-associated OD risk following the reformulation but only in commercially insured individuals receiving single-opioid regimens.
