What Perioperative Factors Are Associated With High-risk Daily Morphine Milligram Equivalent Totals in Spinal Decompressions?

Patients with high MME per day who underwent spinal decompression were significantly younger with higher BMIs and preoperative VAS with an increased incidence of preoperative opioid use and intraoperative ketamine. A closer look at interaction models revealed that a combination of high preoperative pain and intraoperative ketamine usage were at a significantly increased risk of higher MME consumption. Preoperative opioid risk education and mitigation strategies should be considered in patients with high MME risk, especially in younger patients already utilizing opioids before surgery.
