Observational StudyPrevalence of Early Posttraumatic Seizures in Children With Moderate to Severe Traumatic Brain Injury Despite Levetiracetam Prophylaxis.
To evaluate the prevalence of early seizures after levetiracetam prophylaxis in children with moderate to severe traumatic brain injury. ⋯ Early clinical posttraumatic seizures occurred frequently in children with moderate to severe traumatic brain injury despite seizure prophylaxis with levetiracetam. Younger children and those with abusive head trauma were at increased risk of seizures. Further studies are needed to evaluate the efficacy of levetiracetam before it is routinely used for seizure prophylaxis in these children, particularly in young children and those who have suffered from abusive head trauma.

Randomized Controlled TrialA Double-Blinded, Randomized, Placebo-Controlled Clinical Trial of Aminophylline to Prevent Acute Kidney Injury in Children Following Congenital Heart Surgery With Cardiopulmonary Bypass.
Acute kidney injury occurs commonly in children following congenital cardiac surgery with cardiopulmonary bypass and has been associated with increased morbidity and mortality. Aminophylline, a methylxanthine nonselective adenosine receptor antagonist, has been effective in the management of acute kidney injury in certain populations. This study sought to determine whether postoperative administration of aminophylline attenuates acute kidney injury in children undergoing congenital cardiac surgery with cardiopulmonary bypass. ⋯ In this placebo-controlled randomized clinical trial, we found no effect of aminophylline to prevent acute kidney injury in children recovering from cardiac surgery performed with cardiopulmonary bypass. Future study of preoperative aminophylline administration to prevent acute kidney injury may be warranted.

ReviewEfficacy of α2-Agonists for Sedation in Pediatric Critical Care: A Systematic Review.
Children in PICUs normally require analgesics and sedatives to maintain comfort, safety, and cooperation with interventions. α2-agonists (clonidine and dexmedetomidine) have been described as adjunctive (or alternative) sedative agents alongside opioids and benzodiazepines. This systematic review aimed to determine whether α2-agonists were effective in maintaining patients at a target sedation score over time compared with a comparator group. We also aimed to determine whether concurrent use of α2-agonists provided opioid-sparing effects. ⋯ Reporting of study results using the outcome "time maintained at target sedation score' for clonidine or dexmedetomidine was poor. Only one trial compared clonidine with midazolam using a sedation score outcome. This study was underpowered to demonstrate equivalence to midazolam as a sedative. The adjunctive use of clonidine demonstrated significant decreases in opioid use in neonates but not in older groups. Clonidine dose was inconsistent between studies. Dexmedetomidine demonstrated an opioid-sparing effect in two small trials. Further studies, including dose-finding studies and studies with sedation score-based outcomes, are needed.

Randomized Controlled TrialThe Effect of Methylprednisolone on Plasma Concentrations of Neutrophil Gelatinase-Associated Lipocalin in Pediatric Heart Surgery.
Plasma neutrophil gelatinase-associated lipocalin is a kidney injury marker used in pediatric heart surgery. Neutrophil gelatinase-associated lipocalin is also a constituent of specific granules of neutrophils. Corticosteroids are widely used in pediatric heart surgery. Methylprednisolone inhibits degranulation of neutrophil-specific granules. Use of corticosteroids has not been taken into account in studies of neutrophil gelatinase-associated lipocalin in pediatric heart surgery. We studied the influence of systemically administered methylprednisolone on plasma neutrophil gelatinase-associated lipocalin concentrations in pediatric heart surgery. ⋯ Preoperatively administered methylprednisolone profoundly decreases plasma neutrophil gelatinase-associated lipocalin levels. Neutrophil gelatinase-associated lipocalin seems to originate to a significant extent from activated neutrophils. Preoperative methylprednisolone is a confounding factor when interpreting plasma neutrophil gelatinase-associated lipocalin levels as a kidney injury marker in pediatric heart surgery.
