Adults who use marijuana experience more pain after surgery than non-marijuana users, according to a study presented at the Anesthesiology 2022 annual meeting.

“Cannabis is the most commonly used illicit drug in the United States and is increasingly used as an alternative treatment for chronic painbut there is limited data showing how it affects patient outcomes after surgery“, said Elyad Ekrami, MD, lead author of the study and clinical research fellow in the Outcomes Research Division at the Cleveland Clinic’s Institute of Anesthesia. Adults cannabis users experience more – not less – after surgery pain. As a result, they had higher opioid consumption after surgery. “

The researchers analyzed the records of 34,521 adult patients — 1,681 of whom were cannabis users — who had elective surgery at the Cleveland Clinic between January 2010 and December 2020. marijuana users used the drug within 30 days before surgery, while other patients had never used marijuana. Patients who used cannabis experienced 14% more pain in the first 24 hours after surgery than patients who never used marijuana. Additionally, cannabis-using patients consumed 7% more opioids after surgery, which the authors note was not statistically significant, but could be clinically relevant.

“The link between use marijuana, pain scores and opioid consumption have been previously reported in smaller studies, but they have conflicting results,” added Dr. Ekrami. Our study had a much larger sample size and did not include patients with a diagnosis of chronic pain or who received regional anesthesia, which would seriously contradict our results. Furthermore, our study groups were balanced by confounding factors including age, gender, tobacco and other illicit drug use, as well as depression and psychosis. . “

Dr. Ekrami notes that additional research is needed to better define the effects of cannabis on surgical outcomes. “Doctors should consider that patients use marijuana may experience more pain and require slightly higher opioid doses after surgery, highlighting the need to continue to explore a multimodal approach to postoperative pain management,” he said.
