Percutaneous subclavian central venous catheterization in children and adolescents: success, complications and related factors.
The objective of this study was to investigate the rates of success and of complications of percutaneous subclavian central venous catheterization in children and adolescents and to identify factors associated with them. ⋯ The chance of success was greater when patients were sedated for catheterization. There was a greater chance of complications related to insertion of the catheter when percutaneous subclavian central venous catheterization was performed by less experienced physicians, and it would be prudent to designate those central venous catheterizations that present greater risk to surgeons with greater experience.

Evaluation of the dead space to tidal volume ratio as a predictor of extubation failure.
The objective of this study was to evaluate the ratio of dead space to tidal volume (VD/VT) as a predictor of extubation failure of children from mechanical ventilation. ⋯ In a pediatric population receiving mechanical ventilation due to a variety of etiologies, the VD/VT ratio was unable to predict the populations at risk of extubation failure or of reintubation.

Evaluation of peak inspiratory pressure and respiratory rate during ventilation of an infant lung model with a self-inflating bag.
To evaluate the peak inspiratory pressure and ventilation rate achieved by physicians when using a neonatal self-inflating bag on a lung model. ⋯ Ventilation rates achieved with the self-inflating bag were adequate in approximately 80% of pressure curves analyzed, but the physicians were unable to provide ventilation with minimal pressure variation, producing pressures that diverged from those defined by the neonatal resuscitation training course in 70% of the curves. This was irrespective of whether they were ventilating the lung model analogous to preterm or full term infant lungs.

Evaluation of peak inspiratory pressure, tidal volume and respiratory rate during ventilation of premature lambs using a self-inflating bag.
To evaluate the peak inspiratory pressure, tidal volume and respiratory rate achieved during manual ventilation of premature lambs, using a self-inflating bag. ⋯ There was major variation in peak inspiratory pressure and tidal volume/kg values, which were in many cases elevated, attaining levels that habitually cause biotrauma, while respiratory rates were adequate in the majority of cases.
