Multicenter Study Observational StudyShort anesthesia without intravenous fluid therapy in children: Results of a prospective non-interventional multicenter observational study.
The German guidelines recommend that intravenous fluid therapy should not be mandatorily performed in children with short fasting times undergoing short anesthesia, but there is a lack of clinical studies including a large number of pediatric patients. Therefore, we performed a prospective non-interventional multicenter observational study to evaluate the perioperative hemodynamic and metabolic stability of children undergoing short anesthesia without intravenous fluid therapy. ⋯ Our study supported the German guidelines recommendation that perioperative intravenous fluid therapy is not mandatory in children beyond the neonatal period with short pre- and postoperative fasting times undergoing short anesthesia (<1 h).

Randomized Controlled TrialA randomized, double-blind, dose-controlled study of the use of dexmedetomidine alone for procedural sedation of children and adolescents undergoing MRI scans.
Dexmedetomidine is a selective α2-adrenergic agonist originally approved for sedation of adults in the intensive care unit and subsequently approved for procedural sedation in adults undergoing medical procedures. Dexmedetomidine is widely used off-label for procedural sedation in children. ⋯ Dexmedetomidine was well tolerated. The high dose was associated with meaningfully greater efficacy compared with lower doses. Based on these results, the recommended starting dose for procedural sedation in children ≥1month-<2years is loading dose 1.5 mcg/kg/maintenance infusion 1.5 mcg/kg/h; children ≥2-<17years is loading dose 2.0 mcg/kg/maintenance infusion 1.5 mcg/kg/h.

Impact of dietary ketosis on volatile anesthesia toxicity in a model of Leigh syndrome.
Genetic mitochondrial diseases impact over 1 in 4000 individuals, most often presenting in infancy or early childhood. Seizures are major clinical sequelae in some mitochondrial diseases including Leigh syndrome, the most common pediatric presentation of mitochondrial disease. Dietary ketosis has been used to manage seizures in mitochondrial disease patients. Mitochondrial disease patients often require surgical interventions, leading to anesthetic exposures. Anesthetics have been shown to be toxic in the setting of mitochondrial disease, but the impact of a ketogenic diet on anesthetic toxicities in this setting has not been studied. ⋯ Our findings suggest that extra caution should be taken in the anesthetic management of mitochondrial disease patients in dietary ketosis.

Determination of optimal positive end-expiratory pressure using electrical impedance tomography in infants under general anesthesia: Comparison between supine and prone positions.
This study determined the optimal positive end-expiratory pressure levels in infants in supine and prone positions under general anesthesia using electrical impedance tomography (EIT). ⋯ The prone position required higher positive end-expiratory pressure than the supine position in mechanically ventilated infants under general anesthesia. EIT is a promising tool to find the optimal positive end-expiratory pressure, which needs to be individualized.
