Medicina intensiva
-
Mechanical ventilation may cause and aggravate lung damage and contribute to the appearance of multiorgan failure. One of the mechanisms that has been described is alveolar hyperoxia. ⋯ Moreover, both the FiO(2) used as well as the PaO(2) achieved in the first 24h of admission are associated with mortality. Clinical trials are needed that assess the threshold of the safe oxygen level for FiO(2) and oxygen saturation.

Comparative Study
[Seasonal influence in characteristics of patients admitted to an intensive care unit].
To investigate seasonal variability in the epidemiology and the outcome of critical illness. ⋯ The stability of our climate implies that this factor does not influence the prognosis of patients who are admitted with critical illness.

Comparative Study
[Pandemic influenza A in the ICU: experience in Spain and Latin America. GETGAG/SEMICYUC/(Spanish Working Group on Severe Pandemic Influenza A/SEMICYUC)].
Pandemic Influenza A (H1N1)v infection is the first pandemic in which intensive care units (ICU) play a fundamental role. It has spread very rapidly since the first cases were diagnosed in Mexico with the subsequent spread of the virus throughout the Southern Cone and Europe during the summer season. ⋯ These data suggest that a more aggressive treatment strategy, with earlier and easier access to the antiviral treatment might reduce the number of ICU admissions and mortality.
