High-frequency oscillatory ventilation in pediatrics and neonatology.
This article intends to review literature on high frequency oscillatory ventilation and describe its main clinical applications for children and neonates. Articles from the last 15 years were selected using MedLine and SciElo databases. The following key words were used: high frequency oscillatory ventilation, mechanical ventilation, acute respiratory distress syndrome, children, and new-born. ⋯ It may be also useful in the air leak syndrome and obstructive pulmonary disease. Evidence that, in neonates, high frequency oscillatory ventilation is superior to conventional mechanical ventilation is lacking. However there is evidence that better results are only achieved with this ventilatory mode to manage the air leak syndrome.

Evaluation of extracurricular internships in the adult's intensive care units.
Students of Salvador - BA, Brazil were trained in critical care medicine by accomplishing extracurricular internships. This study aims to detect changes in attitude and interest of students who concluded these internships as well as the most frequent activities developed. ⋯ This study showed that internships in adult intensive care units of Salvador (BA), Brazil provided students with greater assurance to evaluate critical patients, increased their interest to follow an intensivist physician career and allowed contact with the main procedures and topics related to critical care medicine.

Effects of respiratory physiotherapy on intracranial pressure and cerebral perfusion pressure in severe traumatic brain injury patients.
After brain injury intracranial hypertension is the major cause of mortality, in addition to the possibility of functional, behavioral and cognitive sequels. Scarcity of studies on the effects of respiratory physiotherapy on these patients may lead to contradictory performances. This study aimed to assess the effects of customary respiratory physiotherapy maneuvers on intracranial and cerebral perfusion pressures in patients with severe brain injury. ⋯ The manual vibrocompression maneuver did not increase intracranial pressure or cerebral perfusion pressure in patients with severe brain injury. Intratracheal aspiration induced a significant and transient increase of the intracranial and cerebral perfusion pressures.

Ramsay and Richmond's scores are equivalent to assessment sedation level on critical patients.
The main purpose of this study was to compare performance of the Ramsay and Richmond sedation scores on mechanically ventilated critically ill patients, in a university-affiliated hospital. ⋯ In this study, Ramsay and Richmond sedation scores were similar for the assessment of deep, insufficient and adequate sedation. Both have good correlation with mortality in over sedated patients.

Central and mixed venous oxygen saturation in septic shock: is there a clinically relevant difference?
Central venous oxygen saturation (SvcO2) has been proposed as an alternative for mixed venous oxygen saturation (SvO2), with a variable level of acceptance according to available data. This study aimed to evaluate possible differences between SvO2 and SvcO2 or atrial venous saturation (SvaO2), with emphasis on the role of cardiac output and their impact on clinical management of the septic patient. ⋯ This study showed that the correlation and agreement between SvO2 and SvcO2 is weak and may lead to different clinical management.
