Comparative StudyComparison of pediatric perioperative risk assessment by ASA physical status and by NARCO-SS (neurological, airway, respiratory, cardiovascular, other-surgical severity) scores.
ASA-PS is a widely used perioperative health assessment method, but with poor reproducibility. A novel objective, pediatric-specific risk classification system based on Neurological, Airway, Respiratory, Cardiovascular, Other categories and Surgical Severity (NARCO-SS) has been validated in only one US center. ⋯ NARCO-SS is a valid risk stratification tool that is better than the ASA-PS in discriminating children with adverse perioperative outcomes. The poor calibration of both scores suggests neither can reliably predict perioperative outcomes in individual patients. Modification of neurological and airway categories may improve the predictive accuracy of the NARCO-SS.

Comparative StudyEvaluation of the minimum volume of salvage blood required for the successful use of two different autotransfusion devices.
Autotransfusion in pediatric anesthesia is beneficial in several clinical settings; however, more frequent usage is deterred by process-related costs and the fact that the absolute volume of blood returned may be minimal. ⋯ Red cell mass rather than salvaged blood volume represents a reliable predictor of the successful use of an autotransfusion device. Measuring the hematocrit of the salvaged blood could improve the use of the devices. The investigated devices are likely to be roughly equivalent in effectiveness.

Ultrasound assessment of gastric volume in the fasted pediatric patient undergoing upper gastrointestinal endoscopy: development of a predictive model using endoscopically suctioned volumes.
Aspiration of gastric contents can be a serious anesthetic-related complication. Gastric antral sonography prior to anesthesia may have a role in identifying pediatric patients at risk of aspiration. We examined the relationship between sonographic antral area and endoscopically suctioned gastric volumes, and whether a 3-point qualitative grading system is applicable in pediatric patients. ⋯ The results suggest that sonographic assessment of the gastric antrum provides useful information regarding gastric content (empty versus nonempty) and volume (ml·kg(-1) ) in pediatric patients. Results suggest that the three-point grading system may be a valuable tool to assess gastric 'fullness' based on a qualitative exam of the antrum.
