Impact of methocarbamol on opioid use after primary ventral and inguinal hernia repair

Abstract

BackgroundMultimodal analgesia is now a mainstay of perioperative care. Our aim is to assess the impact of adding methocarbamol on opioid use for patients undergoing primary ventral (umbilical and epigastric) hernia repair (PVHR) and inguinal hernia repair (IHR). MethodsRetrospective review of patients undergoing PVHR and IHR who received methocarbamol, propensity score matched in a 2:1 fashion to patients not receiving methocarbamol. ResultsFifty-two PVHR patients receiving methocarbamol were matched to 104 control patients. Study patients were prescribed fewer opioids (55.8 vs 90.4%; p < 0.001) and received lower MME (20 vs 50; p < 0.001), with no difference in refills or rescue opioids. For IHR, study patients received fewer prescriptions (67.3 vs 87.5%; p < 0.001) and received lower MME (25 vs 40; p < 0.001), with no difference in rescue opioid (5.9 vs 0%; p = 0.374). ConclusionsMethocarbamol significantly reduced opioid prescribing in patients undergoing PVHR and IHR without increasing the risk of refill or rescue opioid.
