We managed 10 cases of propofol anesthesia with rocuronium, and recorded the time course of the neuromuscular blockade evaluated through accelerometry, as well as the estimated blood concentrations of rocuronium calculated from the administration history with a pharmacokinetic simulation analysis. Rocuronium was injected at 0.6 mg x kg(-1) initially, and the infusion rates were managed in order to maintain a twitch height at 3-10% of the control. ⋯ The time to spontaneous recovery with a twitch height of 25% and a reappearance of the fourth response in train-of-four ratio (TOF ratio) nerve stimulation was twenty minutes, even after a five-hour infusion, and was not affected by the length of the infusion. Thus, continuous infusion of rocuronium might be an effective and safe way to maintain appropriate neuromuscular blockade.

Comparative Study
[Landmark method and ultrasound-guided method of internal jugular vein puncture: comparison of residents with staffs].
We compared landmark with ultrasound-guided methods of internal jugular vein puncture in residents and staffs. ⋯ Residents need more practice of internal jugular vein puncture on a manikin before clinical practice.

In Japan, endovascular abdominal aneurysm repair became one of the standard procedures in 2006. It has been performed in 8 patients at our hospital. ⋯ We usually use radiographic monitoring for safe and precise insertion of the catheter into the epidural space. Epidural catheterization with radiographic monitoring is useful for safe and reliable epidural analgesia.
