Opioid free regimens

Background

• The shift in pain management from a symptomatic approach to a mechanistic approach has allowed providers to address pain in a more targeted and efficient manner
• By recognizing the pain receptors that are the culprit behind a patient’s symptoms, a higher level of care can be administered

• IV Dexmedetomidine 02.-0.3 mcg/kg/hour continuous infusion

Benefits

• The cycle of opioid abuse and addiction often arises with the first time administration of opioids in the ED for a variety of medical complaints. Limiting this exposure is one of the ways providers can help combat this epidemic
• A better understanding of underlying pain mechanisms will also likely result in overall improvement in pain management and satisfaction

Feasibility

• A recent study being done at Maimonides hospital designed an 8 hour opioid free ED shift that resulted in over 80% pain satisfaction scores at 30 and 60 minutes and no opioids used during the shift with just one opioid prescription written

Weaknesses:

• During above study, a challenge was managing staff that had little experience in using medications for off label uses.
• Certain subsets of patients will have various contraindications that will need to be considered such as patients with cardiovascular disease and NSAIDs. Those contraindications will not be reviewed on this page.
