Randomized Controlled Trial Clinical TrialEffects of low dose ketamine before induction on propofol anesthesia for pediatric magnetic resonance imaging.
We aimed to investigate effects of low dose ketamine before induction on propofol anesthesia for children undergoing magnetic resonance imaging (MRI). ⋯ Intravenous administration of low dose ketamine before induction and maintenance with propofol preserves hemodynamic stability without changing the duration and the quality of recovery compared with propofol alone.

Clinical Trial Controlled Clinical TrialLevobupivacaine spinal anesthesia in neonates: a dose range finding study.
Our aim was to determine the clinical efficacy of levobupivacaine for awake spinal anesthesia in ex-premature infants having lower abdominal surgery. The secondary aim was to determine the minimum local analgesic dose (MLAD) defined as the median effective local anesthetic dose for spinal anesthesia in neonates. ⋯ Levobupivacaine is an effective agent for spinal anesthesia in neonates at a recommended dose of 1 mg x kg(-1). It appears to be of equivalent potency to racemic bupivacaine for motor blockade in ex-premature infants requiring lower abdominal surgery.

Droperidol for perioperative sedation causes a transient prolongation of the QTc time in children under volatile anesthesia.
Droperidol is useful for postoperative sedation in infants and children after cardiac surgery because it provides sedation and akinesia with minimal respiratory depression. However, droperidol has been associated with QT prolongation and ventricular arrhythmias. We investigated, if neuroleptanalgesic doses of droperidol led to QT prolongation and cardiac arrhythmias in children undergoing cardiac surgery. ⋯ The statistically significant prolongation of QTc time after a sedative dose of droperidol is of concern because it may increase the risk for malignant cardiac arrhythmias. A large, prospective study is necessary to identify the true risk for arrhythmias after droperidol in this patient population, but our study suggests that any arrhythmogenic risk, if present, will be very transient, since the increase in QTc time was limited to a period of less than 30 min after the bolus.
