Examining Analgesic Synergy and Efficacy in Trauma Care

Overview

Traumatic injury is responsible for over 25 million (16%) Emergency Department visits and over 225,000 deaths each year per 2021 Center for Disease Control data. This is the 3rd leading cause of death in the US. Often, acute care for the injured patient requires administration of pain medication for the purposes of acute pain control from injury. The mainstay of treatment for pain control has historically involved opioid pain medication.

A different medication which has been used in place of full agonist opioids is a product known as buprenorphine, which was developed in the 1960's. This medication works as a partial agonist/antagonist of the µ opioid pain receptors. It has performed robustly in comparison to full opioid agonist (FAO) medications, and in a recent meta-analysis of this medication, it was responsible for reducing pain, less rescue analgesia use, and similar rates of adverse events in comparison to full opioid agonist therapy. This also concurrently lowered the amount of Morphine Milligram Equivalents (MME) used by the postoperative patients, although the achievement of lower pain scores is the significant finding. These data assert that buprenorphine is more efficacious than FAO in mitigating acute post op pain due to comparable analgesic effect and longer duration of action when compared to many other oral opioids. This medication has been commonly used in patients with opioid abuse disorder and has shown improvements in specific patient outcome metrics when induction therapy is performed in hospital for patients with opioid use disorder (OUD). Further, continuation of buprenorphine for patients taking the medication as an outpatient for acute pain control has been shown to be safe, and to have similar efficacy to discontinuation in favor of standard pain regimen therapy.
