Multicenter StudySafety of Antifibrinolytics in 6583 Pediatric Patients Having Craniosynostosis Surgery: A Decade of Data Reported from the Multicenter Pediatric Craniofacial Collaborative Group.
Antifibrinolytics such as tranexamic acid and epsilon-aminocaproic acid are effective at reducing blood loss and transfusion in pediatric patients having craniofacial surgery. The Pediatric Craniofacial Collaborative Group has previously reported low rates of seizures and thromboembolic events (equal to no antifibrinolytic given) in open craniofacial surgery. ⋯ This multicenter international experience of pediatric craniofacial surgery reports no increase in seizures or thromboembolic events in those that received antifibrinolytics (tranexamic acid and epsilon-aminocaproic acid) versus those that did not. This report provides further evidence of antifibrinolytic safety. We recommend following pharmacokinetic-based dosing guidelines for administration.

Levobupivacaine plasma concentrations following repeat caudal anesthetics.
A single caudal anesthetic at the start of lower abdominal surgery is unlikely to provide prolonged analgesia. A second caudal at the end of the procedure extends the analgesia duration but total plasma concentrations may be associated with toxicity. Our aim was to measure total plasma levobupivacaine concentrations after repeat caudal anesthesia in infants and to generate a pharmacokinetic model for prediction of plasma concentrations after repeat caudal anesthesia in neonates, infants and children. ⋯ Repeat caudal levobupivacaine 2.5 mg kg-1 at 3 h after an initial 2.5 mg kg-1 dose does not exceed the concentration associated with systemic local anesthetic toxicity. In 2.5% of simulated neonates (weight 3.8 kg, PMA 40 weeks), repeat caudal anesthesia demonstrates broaching of the lower concentration limit associated with toxicity at both 3 and 4 h after initial caudal.

Justification Of Empiric Methodology to Determine Dexmedetomidine Dose for the TREX Study.
Dexmedetomidine is the sedative agent administered in combination with remifentanil and low dose of sevoflurane in the interventional arm of the ongoing TREX trial (Trial Remifentanil DExmedetomidine). The TREX pilot study (published in Paediatr Anaesth 2019;29:59-67) established infusion rates higher than those initially proposed. This could be attributed to an inappropriate target concentration for sedation or incorrect initial pharmacokinetic parameter estimates. ⋯ This current PK analysis from the Italian arm of the TREX study confirms that plasma concentration of dexmedetomidine is predictable using known covariates such as age and size. The initial target concentration (0.6 μg.L-1 ) used to sedate children cared for in the intensive care after cardiac surgery was inadequate for infants in the current TREX study. A target concentration 1 mcg.L-1 , corresponding to a loading dose of 1 mcg.kg-1 followed by an infusion of 1 mcg.kg-1 .hour-1 , provided adequate sedation.

ReviewMaking quality improvement data more accessible and understandable: analyst, designer, and storyteller.
Making data more accessible and understandable in quality improvement requires a diversity of approaches beyond formal teaching in technical skills of measurement. Improvement practitioners might co-opt the wider skillset of analyst, designer, and storyteller in tailoring the team strategy needed to make best use of the data used to inform decision-making at the point of care. Data literacy levels, negative prior experiences, or limited access to technology might influence the ability of teams to engage in measurement. ⋯ Thoughtful data visualization takes account of the inherent perceptual challenges of comprehending data and complex images. Establishing a routine of simplification-removing redundant elements and distractions-and amplifying aspects that aid understanding can bring clarity to the important concepts within a chart. Story-telling techniques can help wider audiences engage with data by carefully shaping analytical and emotional content around a central narrative-always mindful of the limitations of working memory, and the emotional momentum needed to inspire change.
