The mortality of postcardiac arrest patients has gradually reduced in years but it still is as high as 50%, despite advancements in the diagnostic and therapeutic approaches, i.e. revascularization and therapeutic moderate hypothermia. However, recent evidence suggests that other therapeutic interventions aimed to minimize progressive deterioration of the brain and other organs function might be helpful to reduce in-hospital mortality and improve neurologic outcome as well as quality of life after cardiac arrest. ⋯ In pediatric patients, hypoxia and hyperoxia were not associated with higher in-hospital mortality, while hypocapnia and hypercabia with higher in-hospital mortality worse neurologic outcome. We propose a general bundle for ventilator treatment after cardiac arrest, including: 1) therapeutic hypothermia for 12-24 hours; 2) mean arterial pressure ≥65-75 mmHg; 3) PaO2 between 60-200 mmHg and PCO2 between 30 and 50 mmHg; 4) protective MV with tidal volume of 6-8 mL/kg and positive end expiratory pressure of between 5-10 cmH2O; 5) monitoring of respiratory mechanics, extravascular lung water, hemodynamics, non-invasive transcranial Doppler and intracranial pressure monitoring; and 6) others supportive care, i.e. blood sugar and seizures control.

Randomized Controlled TrialValidity and fidelity of the upper airway in two high-fidelity patient simulators.
Human patient simulators are frequently used for airway management training and research. However, little is known about their fidelity and validity. The use of these simulators as a benchmark model remains highly questionable. The objective of this study was to evaluate the validity and fidelity of two patient simulators (compared to actual patients) for anaesthesia residents performing three airway management techniques. ⋯ Patient simulators are not a valid alternative to human patients for conducting scientific evaluations of supraglottic airway management techniques. HAL and SimMan do have adequate validity for endotracheal intubation, but the fidelity and validity are low when a laryngeal mask is used or if mask ventilation is performed. Therefore, previous simulation-based airway device evaluation studies must be interpreted with great caution.

ReviewNovel multi-drug resistant microorganisms in critically ill: a potential threat.
Infections due to multidrug resistant (MDR) pathogens are among the major threats in critically ill patients. Reduced vancomycin susceptibility in Staphylococcus aureus, high-level aminoglycoside resistance in enterococci, extended spectrum beta-lactamase and carbapenemases production in Enterobacteriaceae, carbapenem and colistin resistance in Pseudomonas spp. and Acinetobacter spp. are increasing in many intensive care units around the world. In the last few years some new anti-Gram-positive agents have been developed, whereas for Gram-negatives the available options are very limited. Infections control and antimicrobial stewardship programs are currently the only available options to avoid a further increase of these pathogens.
