The perioperative course of factor XIII and associated chest tube drainage in newborn and infants undergoing cardiac surgery.
Perioperative acquired factor XIII deficiency has been looked upon as a potential cause of postoperative bleeding in adult cardiac surgery. ⋯ Factor XIII activity in infants with congenital heart defects is within the lower range of normal adults, independent of patient's age and the presence of cyanosis. Reconstituted blood prime maintains factor XIII activity at sufficient levels during pediatric cardiac surgery. We could not detect a correlation between FXIII and CTD.

Minimum alveolar concentration of desflurane with caudal analgesia for laryngeal mask airway removal in anesthetized children.
Regional blocks have been shown to decrease the requirement of anesthetic agents. This study was conducted to determine the optimal endtidal concentrations of desflurane for removal of Laryngeal mask airway in children in presence of caudal block. ⋯ Laryngeal mask airway can be successfully removed in 50% of anesthetized children without coughing, moving, or any other airway complications at an endtidal desflurane concentration of 3.4% in the presence of caudal analgesia.

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.

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.
