[Clonidine associated to morphine and midazolam in children submitted to mechanical ventilation: randomized, double blind and placebo controlled study].
In our country, the abstinence syndrome has high prevalence and besides the distress prolongs the length of hospital stay. The aim of this study was to evaluate the influence of associating oral clonidine to the intravenous morphine plus midazolam continuous infusion in children submitted to mechanical ventilation. ⋯ In children submitted to mechanical ventilation using high dose of opioids and diazepinic infusion the addiction of clonidine did not decrease the daily doses neither the cumulative doses and nevertheless reduced the prevalence and the evolution of abstinence syndrome.

The II Brazilian Consensus Conference on Mechanical Ventilation was published in 2000. Knowledge on the field of mechanical ventilation evolved rapidly since then, with the publication of numerous clinical studies with potential impact on the ventilatory management of critically ill patients. Moreover, the evolving concept of evidence - based medicine determined the grading of clinical recommendations according to the methodological value of the studies on which they are based. This explicit approach has broadened the understanding and adoption of clinical recommendations. For these reasons, AMIB - Associação de Medicina Intensiva Brasileira and SBPT - Sociedade Brasileira de Pneumologia e Tisiologia - decided to update the recommendations of the II Brazilian Consensus. Physical therapy during mechanical ventilation has been one of the updated topics. This objective was described the most important topics on the physical therapy during mechanical ventilation. ⋯ Physical therapy has a central role at the Intensive Care environment, mainly in patients submitted to a mechanical ventilatory support invasive or non invasive.

Agreement and correlation of pH, bicarbonate, base excess and lactate measurements in venous and arterial blood of premature and term infants.
Determine the extent of agreement and correlation between arterial samples and venous (obtained from a venous umbilical catheter), with respect to measurements of pH, bicarbonate, base excess and lactate, in critically ill term and premature newborns. ⋯ Although single venous values cannot be used as equivalent to arterial for assessing acid base status in newborns, venous blood samples can be used serially for monitoring trends over time.

Weaning from mechanical ventilation has been one of the updated topics. This objective was described the most important topics related to weaning from mechanical ventilation. ⋯ Weaning is a very important period of mechanical ventilatory support. Weaning protocols are recommended to select patients ready to be extubated.

[Cuff leak test preextubation: comparison between three methods in spontaneous ventilation].
The cuff leak test aims to evaluate the presence of airway obstruction and normally is carried through in the controlled mode of mechanical ventilation. The objective of this study was to evaluate the cuff leak in patients breathing spontaneously, across three different methods, and to compare them. ⋯ The cuff leak test in spontaneous ventilation seems to be more accurate when the patient is connected to the mechanical ventilator, and that additional studies are needed to determine the real contribution of the test in this ventilation mode to predict laryngeal edema.
