This study assessed the association between standing intravenous acetaminophen and opioid exposure after cardiac surgery. Before vs after implementation of a standardized pain pathway, we report decreased opioid exposure, 0.38 milligram per kilogram of morphine equivalents [IQR 0.10-0.81] vs 0.26 milligram per kilogram of morphine equivalents [0.09-0.56] (P = .01) and increased acetaminophen exposure, 3 [2-4] vs 4 [4-5] doses (P < .001).
Keywords: cardiac surgery; multimodal analgesia; opioid-sparing.
