Effects of dexmedetomidine on propofol and remifentanil infusion rates during total intravenous anesthesia for spine surgery in adolescents.
Total intravenous anesthesia with propofol and a synthetic opioid is a frequently chosen anesthetic technique for posterior spinal fusion. Despite its utility, adverse effects may occur with high or prolonged propofol dosing regimens including delayed awakening. The current study investigated the propofol-sparing effects of the concomitant administration of the alpha(2)-adrenergic agonist, dexmedetomidine, during spinal fusion surgery in adolescents. ⋯ The concomitant use of dexmedetomidine in patients undergoing spinal fusion reduces propofol infusion requirements when compared with those patients receiving only propofol and remifentanil.

Randomized Controlled Trial Comparative StudyThe effects of 45 degree head up tilt on the lumbar puncture success rate in children undergoing spinal anesthesia.
There are few studies for procedural techniques of lumbar puncture (LP) for spinal anesthesia in children. There are no controlled studies on the effect of patient positioning. We designed this prospective, randomized study to compare the success rates of LP of the lateral decubitus and lateral decubitus position with a 45 degree head up tilt in children undergoing spinal anesthesia. ⋯ Because of higher success rate, lateral decubitus, knee-chest position with 45 degree head up tilt may be the preferred position for spinal anesthesia in infants.
