Hemodynamic response to ketamine in children with pulmonary hypertension.
The safety of ketamine in children with pulmonary hypertension has been debated because of conflicting results of prior studies in which changes in mean pulmonary artery pressure (mPAP) and pulmonary vascular resistance (PVR) have been widely variable. The goal of this prospective study was to quantitate the effects of ketamine on pulmonary hemodynamics in a cohort of children with pulmonary hypertension under conditions in which variables such as airway/ventilatory management, FiO(2), and use of vasodilating anesthetics were controlled. ⋯ Ketamine is associated with minimal, clinically insignificant hemodynamic changes in sedated, mechanically ventilated children with pulmonary hypertension.

ReviewA systematic review of methodology applied during preclinical anesthetic neurotoxicity studies: important issues and lessons relevant to the design of future clinical research.
Preclinical evidence suggests that anesthetic agents harm the developing brain thereby causing long-term neurocognitive impairments. It is not clear if these findings apply to humans, and retrospective epidemiological studies thus far have failed to show definitive evidence that anesthetic agents are harmful to the developing human brain. ⋯ Comparison between studies is thus complicated by this heterogeneous methodology and the relevance of the combined body of literature to humans remains uncertain. Future preclinical studies should use better standardized methodologies to facilitate transferability of findings from preclinical into clinical science.

Randomized Controlled TrialEconomic aspects of intraoperative coagulation management targeting higher fibrinogen concentrations during major craniosynostosis surgery.
Results of a previously published study demonstrated a significant decrease in transfusion requirements and calculated blood loss for pediatric major craniosynostosis surgery, if a ROTEM(®) FIBTEM trigger of <13 mm (early substitution group) was applied as compared to a trigger of <8 mm (conventional group). The aim of this study was a posthoc analysis of the costs for this coagulation management. ⋯ In this study, the use of a higher fibrinogen trigger was not linked to a significant increase in total costs for transfused blood products and coagulation factors, and may offer an economically equivalent approach to coagulation management.

Case ReportsThe presumed central nervous system effects of rocuronium in a neonate and its reversal with sugammadex.
We describe a 2-day-old male infant who received rocuronium as part of general anesthesia for a tracheal esophageal fistula repair. Postoperatively, he had prolonged central and peripheral neuromuscular blockade despite cessation of the rocuronium infusion several hours previously. This case discusses the presumed central nervous system effects of rocuronium in a neonate and its effective reversal with sugammadex.

Neurotoxicity, general anesthesia in young children, and a survey of current pediatric anesthesia practice at US teaching institutions.
Recent articles in both scholarly journals and the lay press about the topic of anesthetic related neurotoxicity have increased the awareness and discussion of this topic with parents and other pediatric medical specialties (i.e., surgeons, radiologists, and pediatricians). ⋯ A significant need exists to provide information to other pediatric professionals and parents. A consistent message from all providers that includes what is known, and indeed more importantly what is not known may be a useful approach.
