Comparative StudyComparison of bicarbonate-buffered fluid and isotonic saline solution as Cell Saver washing fluids for packed red blood cells.
Massive transfusion (MT) can cause severe electrolyte and acid-base disturbances in neonates and infants due to the unphysiological composition of packed red blood cells (PRBCs). Washing of the PRBCs using Cell Saver systems prior to MT is recommended for this reason. ⋯ Washing of PRBCs with BB-HS rather than NaCl results in a more physiological composition with improvements of electrolyte concentrations, acid-base balance and erythrocyte stability.

Features of lateral cephalograms associated with difficult laryngoscopy in Japanese children undergoing oral and maxillofacial surgery.
Difficult laryngoscopy and tracheal intubation are occasionally encountered in children with congenital anomalies or micrognathia. However, no study has elucidated anatomical etiology in relation to craniofacial development. ⋯ Difficult laryngoscopy and tracheal intubation are expected in children aged <4 years with lower-positioned hyoid bone caused by caudal larynx as well as undeveloped maxilla and mandible, and in those aged ≥4 years with increased inclination of the mandible as well as undeveloped mandible.

Direct laryngoscopy after potential difficult intubation in children only predicts standard Cormack and Lehane view to within one grade.
Some techniques used to achieve intubation in children predicted to have a difficult airway do not involve direct laryngoscopy or assessment of the laryngeal grade. Direct laryngoscopy may therefore be performed immediately after intubation to provide a record for future anesthetics. It is unknown whether this postintubation grade accurately reflects the standard laryngeal grade in this group. ⋯ Assessment and documentation of a postintubation laryngeal grade does not appear to provide reliable information for future anesthetics and may even have the potential to be misleading. Any such documentation should always refer to the presence of an endotracheal tube and be interpreted with caution.

Inspired gas humidity and temperature during mechanical ventilation with the Stephanie ventilator.
To measure inspired gas humidity and temperature delivered by a Stephanie neonatal ventilator with variations in (i) circuit length; (ii) circuit insulation; (iii) proximal airway temperature probe (pATP) position; (iv) inspiratory temperature (offset); and (v) incubator temperatures. ⋯ Long insulated Stephanie circuits should be used for neonatal ventilation when the infant is nursed in an incubator. The recommended inspiratory temperature (offset) of 37(-0.5)°C produced inspired humidity and temperature below international standards, and we suggest an increase to 39(-2.0)°C.

A review of 5434 percutaneous pediatric central venous catheters inserted by anesthesiologists.
To review the results of an anesthesiologist led pediatric percutaneous central venous access service. ⋯ This study demonstrates a high success rate and low complication rate during pediatric percutaneous internal jugular vein CVC insertions by trained anesthesiologists using LTs. Smaller children, hemodialysis CVCs, and the team's learning curve were identified as risk factors for insertion failure.
