Randomized Controlled Trial Multicenter Study Clinical Trial
Early reversal of rapacuronium with neostigmine.
Rapacuronium is a rapid-onset, short-acting neuromuscular relaxant. This multiple-center study determined neuromuscular recovery when neostigmine was given 2 or 5 min after rapacuronium. ⋯ Recovery of intense rapacuronium block was accelerated by early neostigmine administration. When given 2 min after rapacuronium, neostigmine was as effective as after 5 min, and 0.05 mg/kg neostigmine was comparable to 0.07 mg/kg neostigmine.

Randomized Controlled Trial Comparative Study Clinical Trial
Ultrasound-guided internal jugular venous cannulation in infants: a prospective comparison with the traditional palpation method.
Percutaneous cannulation of the internal jugular vein in infants is technically more difficult and carries a higher risk of carotid artery puncture than in older children and adults. In this prospective study, the authors tested their hypothesis that using an ultrasound scanner would increase the success of internal jugular cannulation and decrease the incidence of carotid artery puncture in infants. ⋯ Ultrasonographic localization of the internal jugular vein was superior to the landmarks technique in terms of overall success, speed, and decreased incidence of carotid artery puncture.

Randomized Controlled Trial Clinical Trial
Rapid tracheal intubation with rocuronium: a probability approach to determining dose.
Rapid tracheal intubation with rocuronium has not been studied using a probability-based approach. The authors aimed to predict doses of rocuronium giving 90% and 95% probability of in intubation within 60 s and to estimate their durations of action. ⋯ After induction with fentanyl and propofol, rocuronium, 1.04 mg/kg gives 95% probability of successful intubation at 60 s.

Operating room (OR) managers seeking to maximize labor productivity in their OR suite may attempt to reduce day-today variability in hours of OR time for which there are staff but for which there are no cases ("underutilized time"). The authors developed a method to analyze data from surgical services information systems to evaluate which management interventions can most effectively decrease variability in underutilized time. ⋯ This method can be used for decision support to determine how to decrease variability in underutilized OR time.
