Randomized Controlled TrialThe influence of a balanced volume replacement concept on inflammation, endothelial activation, and kidney integrity in elderly cardiac surgery patients.
A balanced fluid replacement strategy appears to be promising for correcting hypovolemia. The benefits of a balanced fluid replacement regimen were studied in elderly cardiac surgery patients. ⋯ A total balanced volume replacement strategy including a balanced HES and a balanced crystalloid solution resulted in moderate beneficial effects on acid-base status, inflammation, endothelial activation, and kidney integrity compared to a conventional unbalanced volume replacement regimen.

Controlled Clinical TrialThe vasopressin and copeptin response in patients with vasodilatory shock after cardiac surgery: a prospective, controlled study.
To evaluate arginine vasopressin (AVP) and copeptin plasma concentrations in patients with vasodilatory shock after cardiac surgery. ⋯ The AVP response to cardiac surgery is significantly different between patients with vasodilatory shock and patients undergoing uncomplicated aorto-coronary bypass surgery. Although no causative relationship between AVP concentrations and cardiovascular instability can be drawn from these results, our data support the hypothesis that inadequately low AVP plasma levels contribute to the failure to restore vascular tone in vasodilatory shock after cardiac surgery.

A new automated method versus continuous positive airway pressure method for measuring pressure-volume curves in patients with acute lung injury.
To compare pressure-volume (P-V) curves obtained with the Galileo ventilator with those obtained with the CPAP method in patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS). ⋯ The PV Tool-2 built into the Galileo ventilator is equivalent to the CPAP method for tracing static P-V curves of the respiratory system in critically ill patients receiving mechanical ventilation.

Predictive factors of non invasive ventilation failure in critically ill children: a prospective epidemiological study.
Identification of predictive factors for non-invasive ventilation (NIV) failure and determination of NIV characteristics. ⋯ NIV is a useful respiratory support technique in paediatric patients. Type 1 group classification, higher PRISM score, and lower RR decrease during NIV were independent risk factors for NIV failure.
