Wrong route medication errors due to tubing misconnections are potentially life-threatening complications that have been made possible by the universal use of the Luer connector. The new International Organization of Standardization standards for small bore connectors, ISO 80369 series, have been developed to reduce the risk of these types of erroneous connections. ⋯ However, design and manufacturing standards have progressed slowly, and clinical roll-outs have been delayed, despite the implementation of California laws to promote their use. We are currently in a state of transition where new connectors for enteral and neuraxial use will be entering the clinical market in the next few years, and increasing use will identify additional patient safety concerns.

Introducing the 6-4-0 fasting regimen and the incidence of prolonged preoperative fasting in children.
Children often starve for longer than recommended by current preoperative fasting guidelines. ⋯ The introduction and implementation of the 6-4-0 fasting regimen reduces median fluid fasting duration and the number of children subjected to extended fasting.

De Barsy syndrome is a rare, autosomal recessive syndrome characterized by cutis laxa, progeroid appearance, ophthalmic opacification, skeletal malformations, growth delays, and intellectual disability. ⋯ This expanded case series suggests that providers caring for patients with de Barsy syndrome should be aware of potential challenges with airway management, vascular access, and temperature monitoring.

Review Meta AnalysisDonohue syndrome: A review of literature, case series, and anesthetic considerations.
Donohue syndrome is a rare autosomal recessive disorder of insulin resistance, causing a functional defect in insulin receptor function, and affecting the ability of the insulin to bind the receptor. Features include severe hyperinsulinism and fasting hypoglycemia, along with severe failure to thrive despite feeding. An accelerated fasting state results in muscle wasting, decreased subcutaneous fat, and an excess of thick skin. A reduced thoracic diameter is accentuated by increased abdominal distension, which impacts on respiratory reserve. Cardiac disease develops early in life, with progressive hypertrophic cardiomyopathy as a result of hyperinsulinism. Prognosis is poor with the majority of patients dying in infancy of sepsis. The aim of this review is to report our experience of providing anesthesia for patients with Donohue syndrome, and inform guidance for safe management of these children, based on a comprehensive literature review. ⋯ There is currently no published literature relating to anesthetic management of Donohue syndrome. We report a case series of 5 patients with Donohue syndrome who have presented to our institution. This small series of children with this complex disorder demonstrates a clearly increased risk of general anesthesia. Many of the risks relate to restrictive lung disease and abdominal distension which worsens with bag valve mask ventilation and limited respiratory reserve which leads to precipitous desaturation. During induction, a spontaneously breathing technique is recommended. If required, bag valve mask ventilation should be accompanied by constant gastric aspiration. Intubation is challenging, and a difficult airway plan, including a second experienced anesthetist and ENT support, should be in place. These children are predisposed to developing cardiomyopathy and therefore at risk of cardiovascular collapse under anesthesia.

ReviewThe anatomy of the pediatric airway: Has our knowledge changed in 120 years? A review of historic and recent investigations of the anatomy of the pediatric larynx.
There is disagreement regarding the anatomy of the pediatric airway, particularly regarding the shape of the cricoid cartilage and the location of the narrowest portion of the larynx. ⋯ In vivo studies do not take into account the motion of the highly pliable laryngeal upper airway structures (aryepiglottic, vestibular, and vocal folds). Maximal abduction of these structures with tracheal tubes or bronchoscopes always demonstrates a larger opening of the glottis compared to the outlet of the cricoid ring. Injury to the larynx depends upon ease of tracheal tube or endoscope passage past the cricoid cartilage and not passage through the readily distensible more proximal structures. The infant larynx is funnel shaped with the narrowest portion the circular or near circular cricoid cartilage confirmed by multiple in vitro autopsy specimens carried out over the past century.
