To know the family needs of patients admitted to our Intensive Care Unit (ICU). ⋯ Most family members were highly satisfied with the care provided to them and their relatives in the intensive care unit, but the need to improve some aspects of the communication with families was identified.

Ventilator-induced lung injury (VILI) is associated to a high rate of mortality with an important social impact. Mechanical ventilation induces structural and ultrastructural alterations in all cell types of the lung and can derive in the transduction of intracellular signals, as well as in changes in the expression of genes, a process known as mechanotransduction. ⋯ VILI can be modulated by means of diverse interventions as the use of protective ventilatory modes, therapeutic approaches based on vasoactive and antioxidative drugs, and more recently treatments based on the use of repairing substances of the surfactant like poloxamers among others. Knowledge of the mechanisms involved in VILI is definitive for a better approach to this condition.

To analyze the limitation of therapeutic effort (LTE) in our Intensive Care Unit (ICU) and the variables associated with that decision. ⋯ LTE is a common practice and is usually performed among the care team and the patient's surrogates. The main variables associated with LSC are those related to the severity of illness, previous quality of life, medical disease and patient's age.

Pseudomonas aeruginosa is a pathogen commonly encountered in clinical practice in critically ill patients. It is a serious cause of infection, associated with a high rate of morbidity and mortality. Inappropriate antimicrobial therapy and delay in starting effective antimicrobial therapy is associated with worse prognostic. ⋯ This combination therapy must be changed to monotherapy on the basis on the specific susceptibility pattern of the initial isolate. In cases without microbiological diagnosis and poor outcome, combination therapy will be maintained and other causes of infection will be studied. Multicentre prospective randomized trials in critically ill patients are needed to determine which antimicrobials combinations improve outcome in Pseudomonas infections.
