Moyamoya syndrome carries a high risk of cerebral ischemia, and impaired cerebrovascular autoregulation may play a critical role. Autoregulation indices derived from near-infrared spectroscopy (NIRS) may clarify hemodynamic goals that conform to the limits of autoregulation. ⋯ NIRS-derived indices may identify hemodynamic goals that optimize autoregulation in pediatric moyamoya.

High-frequency micro-ultrasound for vascular access in young children--a feasibility study by the High-frequency UltraSound in Kids studY (HUSKY) group.
Cannulation of small arteries and veins in young children can be challenging. Although anesthesiologists frequently use ultrasound for placement of central venous lines and nerve blocks, its use for cannulation of small, peripheral vessels is less helpful. Ultrasound systems (7-15 MHz) currently used in clinical practice focus poorly at the sub-10-mm space and thus lack the resolution to allow accurate ultrasound-guided cannulation of small vessels. High-frequency micro-ultrasound (HFMU) is a new technology that allows higher resolution (15-50 MHz) compared with conventional ultrasound. Limited human studies have been performed thus far with HFMU, and none have been performed in young children or for vascular access. ⋯ The experience gained in this feasibility study suggests that HFMU could be a valuable addition to our armamentarium for difficult vascular access in the future.

Review Meta AnalysisOpioid-sparing effects of perioperative paracetamol and nonsteroidal anti-inflammatory drugs (NSAIDs) in children.
Addition of paracetamol or NSAIDs significantly reduces post-operative opioid consumption in children, although not demonstrably opioid side effects.

Multicenter StudyPediatric cardiopulmonary arrest in the postanesthesia care unit: analysis of data from the American Heart Association Get With The Guidelines-Resuscitation registry.
Nearly 20% of anesthesia-related pediatric cardiopulmonary arrests (CPAs) occur during emergence or recovery. The aims of this study were to describe (i) the nature of pediatric postanesthesia care unit (PACU) CPA and subsequent outcomes and (ii) factors associated with mortality. ⋯ This study identified similar risk factors and underlying causes as described in previous reports of pediatric perioperative CPA, with higher mortality following a cardiac/hemodynamic cause.
