The prevalence of substance use disorder in the liver transplantation (LT) population makes postoperative pain management challenging. We report our initial experience with a novel, comprehensive, multidisciplinary opioid avoidance pathway in 13 LT recipients between January 2018 and September 2019. Patients received comprehensive pre‐LT education on postoperative opioid avoidance by the surgeon, pharmacist, and psychologist at the time of listing. Immediately after LT, patients received a continuous incisional ropivacaine infusion, ketamine, acetaminophen, and gabapentin as standard nonopioid medications; rescue opioids were used as needed. We compared outcomes with a historical cohort of 27 LT recipients transplanted between August 2016 and January 2018 managed primarily with opioids. On average, opioid avoidance patients used 92% fewer median (interquartile range [IQR]) morphine milligram equivalents (MMEs) versus the historical cohort (7 [1‐11] versus 87 [60‐130] MME; P < 0.001) per postoperative day over a similar length of stay (8 [7‐10] versus 6 [6‐10] days; P = 0.14). Fewer outpatient MMEs were prescribed within the first 60 days after LT in the opioid avoidance group versus the historical cohort: 125 (25‐150) versus 270 (0‐463) MME (P = 0.05). This proof‐of‐concept study outlines the potential to profoundly reduce opioid utilization in the LT population using a comprehensive multidisciplinary approach.
Most pharmacologic interventions that have been tried in an effort to prevent or ameliorate POI are ineffective or cause intolerable adverse effects. Research is needed to identify and develop new drug therapies for POI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
