Randomized Controlled TrialXenon as an adjuvant to sevoflurane anesthesia in children younger than 4 years of age, undergoing interventional or diagnostic cardiac catheterization: A randomized controlled clinical trial.
Xenon has repeatedly been demonstrated to have only minimal hemodynamic side effects when compared to other anesthetics. Moreover, in experimental models, xenon was found to be neuroprotective and devoid of developmental neurotoxicity. These properties could render xenon attractive for the anesthesia in neonates and infants with congenital heart disease. However, experience with xenon anesthesia in children is scarce. ⋯ Our observations suggest that combining xenon with sevoflurane in preschool children is safe, feasible, and facilitates hemodynamic management. Larger and adequately powered clinical trials are warranted to investigate the impact of xenon on short- and long-term outcomes in pediatric anesthesia.

Comparative StudyA retrospective comparison of thoracic epidural infusion and multimodal analgesia protocol for pain management following the minimally invasive repair of pectus excavatum.
Pain management following minimally invasive repair of pectus excavatum is variable. We recently adopted a comprehensive multimodal analgesic protocol that standardizes perioperative analgesic management. We hypothesized that patients managed with this protocol would use more opioids postoperatively, have similar pain control, and shorter length of stay compared to patients managed with thoracic epidural infusion. ⋯ Implementation of a standardized comprehensive multimodal analgesic protocol following minimally invasive repair of pectus excavatum resulted in equivalent analgesia with a modest reduction in length of stay when compared to thoracic epidural. We did not observe an opioid sparing effect in our thoracic epidural which may reflect technique variability.

Role of ultrasound measuring position and ventilation pressure in determining correct tube size in children.
Ultrasound measurements of the airway are useful for determining correctly sized, uncuffed endotracheal tubes in children. ⋯ The airway level selected for ultrasound and airway pressure during measurement determines the rate of agreement between the measurement result and correct ETT size.

ReviewWhat is the best size predictor for dose in the obese child?
Lean body mass is commonly proposed for anesthesia maintenance drug dosing calculations. However, total body mass used with allometric scaling has been shown to be better for propofol in obese adults and children. Fat-free mass has also been used instead of lean body mass. ⋯ This fraction (Ffat) will differ for each drug and each parameter affected by body size (eg, clearance and volume of distribution). This fraction is based on the concept of theory-based allometric size. The normal fat mass based on allometric theory and partition of body mass into fat and fat-free components provides a principle-based approach explaining size and body composition effects on pharmacokinetics of all drugs in children and in adults.
