Intravenous Acetaminophen Reduced the Use of Opioids Compared With Oral Administration After Coronary Artery Bypass Grafting

Conclusions: Intravenous acetaminophen had a limited opioid-sparing effect when compared with oral administration after coronary artery bypass graft surgery. The opioid-sparing effect was not accompanied by any reduction in the incidence of PONV. The clinical significance of the opioid-sparing effect could therefore be questioned.
