ReviewSurfactant from neonatal to pediatric ICU: bench and bedside evidence.
Surfactant is a cornerstone of neonatal critical care for the treatment of respiratory distress syndrome of preterm babies. However, other indications have been studied for various clinical conditions both in term neonates and in children beyond neonatal age. A high degree of evidence is not yet available in some cases and this is due to the complex and not yet totally understood physiopathology of the different types of pediatric and neonatal lung injury. ⋯ On the whole, surfactant is able to improve oxygenation in infection related respiratory failure, pulmonary hemorrhage and meconium aspiration syndrome. Bronchoalveolar lavage with surfactant solution is currently the only means to reduce mortality or need for extracorporeal life support in neonates with meconium aspiration. While surfactant bolus or lavage only improves the oxygenation and ventilatory requirements in other types of postneonatal acute respiratory distress syndrome (ARDS), there seems to be a reduction in the mortality of small infants with RSV-related ARDS.

ReviewCorticosteroids as adjunctive treatment in Community-Acquired Pneumonia.
Community-acquired Pneumonia (CAP) is the first leading infectious cause of death in developed countries. The mortality rate in severe CAP is very high and has not changed in recent years, despite advances in antimicrobial therapy and supportive measures. Several studies have identified an excessive host inflammatory response as a marker of poor prognosis in CAP. ⋯ However, two recent meta-analyses found improved mortality in the subgroup with severe CAP and/or receiving >5 days of glucocorticoid treatment. Dosage, duration of treatment and side effects are two important aspects not well determined yet. This review discusses the association of corticosteroids as adjunctive therapy and its association with clinical outcomes and side effects in patients with CAP.

Comparative StudyExtended versus bolus infusion of meropenem and piperacillin: a pharmacokinetic analysis.
Extended infusion of beta-lactam antibiotics has been advocated as a method for optimizing antibiotic exposure in critically ill patients. The objective of this study was to compare the pharmacokinetics/pharmacodynamics of extended infusion versus bolus infusion of piperacillin and meropenem in critically ill patients with normal renal function. ⋯ This study confirms that extended infusion in critically ill patients result in advantageous pharmacokinetic profiles by increasing the fT>MIC for piperacillin and meropenem. In a significant subpopulation of critically ill patients with normal renal function, a 100% fT>MIC target is not reached, even with 3-hour extended infusions.

Observational StudyArterial lactate for predicting mortality in children requiring extracorporeal membrane oxygenation.
Dynamic arterial lactate indices predict mortality more accurately than static arterial lactate measurements in children with septic shock or congenital cardiac defects. The current study evaluates whether this also applies to children with primary respiratory disease requiring extracorporeal membrane oxygenation (ECMO). ⋯ Static arterial lactate measurements and, to a lesser extent, dynamic arterial lactate indices predict mortality in pediatric, but not neonatal ECMO patients. The magnitude and trend over time rather than the duration of lactate derangement are associated with mortality.

Resistive Index or Color-Doppler Semi-Quantitative Evaluation of Renal Perfusion by Inexperienced Physicians: Results of a pilot study.
Doppler-based renal resistive index (RI) calculation may help in the early detection of acute kidney injury (AKI). Its feasibility and reproducibility by inexperienced operators remain unknown. The main objective of this study was to compare performances of junior and senior operators in assessing renal perfusion using both the semiquantitative color-Doppler scale and RI calculation. ⋯ A brief course on renal Doppler allowed inexperienced operators to assess effectively renal perfusion with a good reliability when compared to senior operators. In addition, our results suggest the good diagnostic performance of both Doppler-based RI and semi-quantitative renal perfusion assessment in predicting short-term renal dysfunction reversibility.
