Randomized Controlled Trial Comparative StudyIntravenous acetaminophen reduced the use of opioids compared with oral administration after coronary artery bypass grafting.
The purpose of this study was to evaluate if intravenous acetaminophen compared to oral administration reduced the consumption of opioids and their side effects without an increase in pain during the stay in the intensive care unit (ICU). ⋯ 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.

Randomized Controlled TrialA randomized controlled clinical trial of real-time needle-guided ultrasound for internal jugular venous cannulation in a large university anesthesia department.
The purpose of this study was to evaluate needle-guided ultrasound for internal jugular venous cannulation in a large university anesthesia department, to determine cumulative cannulation success by method, to determine first-pass cannulation success by method and operator, and to determine arterial puncture by method and operator. ⋯ Although the needle guide facilitates prompt cannulation with ultrasound in the novice operator, it offers no additional protection against arterial puncture. This may be because of a lack of control of needle depth rather than needle direction. A possible solution may be biplanar ultrasound for central venous cannulation.
