Many aspects of ventilatory management in patients with ARDS are still controversial and one of the major controversies is should HFO or CMV ideally be used to manage this patients. As shown by David et al. when the two approaches to ventilatory support are applied using similar principles the physiologic outcomes appear to be similar. ⋯ The key to managing ARDS regardless of mode is to use an open lung protective ventilatory strategy. It is not the mode that makes the difference, it is the approach used to apply the mode!

Comparative Study
Arginine-vasopressin in catecholamine-refractory septic versus non-septic shock in extremely low birth weight infants with acute renal injury.
The aim of this study was to assess the efficacy of arginine-vasopressin (AVP) as a rescue therapy in catecholamine-refractory septic and non-septic shock in extremely low birth weight (ELBW) infants with acute renal injury. ⋯ AVP may be a promising rescue therapy in catecholamine-resistant shock in ELBW infants with acute renal injury. Larger prospective clinical trials are warranted to assess the efficacy and safety of AVP as a pressor adjunct in septic versus non-septic shock in ELBW infants.

Comparative Study
Procalcitonin, lipopolysaccharide-binding protein, interleukin-6 and C-reactive protein in community-acquired infections and sepsis: a prospective study.
Clinicians are in need of better diagnostic markers in diagnosing infections and sepsis. We studied the ability of procalcitonin, lipopolysaccharide-binding protein, IL-6 and C-reactive protein to identify patients with infection and sepsis. ⋯ C-reactive protein, IL-6 and lipopolysaccharide-binding protein appear to be superior to procalcitonin as diagnostic markers for infection and sepsis in patients admitted to a Department of Internal Medicine. Procalcitonin appears to be superior as a severity marker.

Hyperlactatemia during cardiopulmonary bypass is relatively frequent and is associated with an increased postoperative morbidity. The aim of this study was to determine which perfusion-related factors may be responsible for hyperlactatemia, with specific respect to hemodilution and oxygen delivery, and to verify the clinical impact of hyperlactatemia during cardiopulmonary bypass in terms of postoperative morbidity and mortality rate. ⋯ Hyperlactatemia during cardiopulmonary bypass appears to be related mainly to a condition of insufficient oxygen delivery (type A hyperlactatemia). During cardiopulmonary bypass, a careful coupling of pump flow and arterial oxygen content therefore seems mandatory to guarantee a sufficient oxygen supply to the peripheral tissues.

Comparative Study
SOFA is superior to MOD score for the determination of non-neurologic organ dysfunction in patients with severe traumatic brain injury: a cohort study.
To compare the discriminative ability of the SOFA and MOD scoring systems with respect to hospital mortality and unfavorable neurologic outcome in patients with severe traumatic brain injury admitted to intensive care. ⋯ In patients with brain injury, the SOFA scoring system has superior discriminative ability and stronger association with outcome compared to the MOD scoring system with respect to hospital mortality and unfavorable neurologic outcome.
