Preemptive Pregabalin in Children and Adolescents Undergoing Posterior Instrumented Spinal Fusion: A Double-Blinded, Placebo-Controlled, Randomized Clinical Trial.

Background: Pregabalin as part of a multimodal pain-management regimen has been shown to reduce opioid consumption after spinal surgery in adults but it is unclear whether this is also true in adolescents. Pregabalin has been found to have neuroprotective effects and therefore could have a positive impact on pain after spinal deformity surgery. We conducted a randomized, double-blinded, placebo-controlled clinical trial of adolescent patients undergoing spinal fusion to evaluate the short-term effects of pregabalin on postoperative pain and opioid consumption.

Back Pain and Quality of Life After Surgical Treatment for Adolescent Idiopathic Scoliosis at 5-Year Follow-up: Comparison with Healthy Controls and Patients with Untreated Idiopathic Scoliosis.

Background: Posterior spinal fusion with pedicle screws is the gold-standard treatment for adolescent idiopathic scoliosis (AIS); however, it is unclear whether this procedure results in improved long-term back pain and health-related quality of life compared with patients not surgically treated for AIS. The aim of the present study was to evaluate back pain and quality of life in surgically managed patients with a minimum follow-up of 5 years compared with patients with untreated AIS and a healthy control group.

Methods: Fifty-five consecutive adolescent patients who underwent posterior pedicle screw instrumentation for AIS by a single orthopaedic surgeon were prospectively enrolled.

Pharmacokinetics and Sedative Effects of Intranasal Dexmedetomidine in Ambulatory Pediatric Patients.

Background: Our aim was to characterize the pharmacokinetics and sedative effects of intranasally (IN) administered dexmedetomidine used as an adjuvant in pediatric patients scheduled for magnetic resonance imaging (MRI) requiring sedation.

Methods: This was an open-label, single-period study without randomization. Pediatric patients from 5 months to 11 years of age scheduled for MRI and receiving IN dexmedetomidine for premedication as part of their care were included in this clinical trial.

Premedication with intranasal dexmedetomidine decreases barbiturate requirement in pediatric patients sedated for magnetic resonance imaging: a retrospective study.

Background: Barbiturates are commonly used in ambulatory sedation of pediatric patients. However, use of barbiturates involve risks of respiratory complications. Dexmedetomidine, a highly selective α-adrenoceptor agonist, is increasingly used for pediatric sedation.

Preoperative pregabalin has no effect on intraoperative neurophysiological monitoring in adolescents undergoing posterior spinal fusion for spinal deformities: a double-blind, randomized, placebo-controlled clinical trial.

Purpose: This study was designed to evaluate the effect of preoperative pregabalin on intraoperative neurophysiological monitoring in adolescents undergoing surgery for spinal deformities.

Methods: Thirty-one adolescents undergoing posterior spinal fusion were randomized to receive preoperatively either pregabalin 2 mg/kg twice daily or placebo. The ability to make reliable intraoperative neurophysiological measurements, transcranial motor (MEPs) and sensory evoked potentials (SSEP) was evaluated.

Mechanism-based population pharmacokinetic and pharmacodynamic modeling of intravenous and intranasal dexmedetomidine in healthy subjects.

Purpose: Dexmedetomidine is an α2-adrenoceptor agonist used for perioperative and intensive care sedation. This study develops mechanism-based population pharmacokinetic-pharmacodynamic models for the cardiovascular and central nervous system (CNS) effects of intravenously (IV) and intranasally (IN) administered dexmedetomidine in healthy subjects.

Method: Single doses of 84 μg of dexmedetomidine were given once IV and once IN to six healthy men.

Bioavailability of dexmedetomidine after intranasal administration.

Purpose: The aim of this proof-of-concept study was to characterize the pharmacokinetics and pharmacodynamics of intranasal dexmedetomidine compared with its intravenous administration in a small number of healthy volunteers.

Methods: Single doses of 84 μg of dexmedetomidine were given once intravenously and once intranasally to seven healthy men. Plasma dexmedetomidine concentrations were measured for 10 h, and pharmacokinetic variables were calculated with standard noncompartmental methods.

Ketoprofen and tramadol for analgesia during early recovery after tonsillectomy in children.

Background: Pain following tonsillectomy is often intense. Nonsteroidal anti-inflammatory drugs and opioids are effective, but both can cause adverse effects. Tramadol may be a viable alternative for post-tonsillectomy pain.
