Recently, dexmedetomidine has been marketed in Spain and other European countries. The published experience regarding its use has placed dexmedetomidine on current trends in sedo-analgesic strategies in the adult critically ill patient. Dexmedetomidine has sedative and analgesic properties, without respiratory depressant effects, inducing a degree of depth of sedation in which the patient can open its eyes to verbal stimulation, obey simple commands and cooperate in nursing care. ⋯ Because of its effects on α2-receptors, it's very useful for the control and prevention of tolerance and withdrawal to other sedatives and psychotropic drugs. The use of dexmedetomidine has been associated with lower incidence of delirium when compared with other sedatives. Moreover, it's a potentially useful drug for sedation of patients in non-invasive ventilation.

Monitoring during mechanical ventilation allows the measurement of different parameters of respiratory mechanics. Accurate interpretation of these data can be useful for characterizing the situation of the different components of the respiratory system, and for guiding ventilator settings. In this review, we describe the basic concepts of respiratory mechanics, their interpretation, and their potential use in fine-tuning mechanical ventilation.

A study was made of the epidemiological data of sepsis requiring admission to the ICU in patients over 65 years of age, with an evaluation of independent predictors of survival at 2 years. ⋯ Sepsis showed different demographic characteristics and clinical presentations in the elderly. In the aging cohort, after adjusting for potential confounders, inadequate empirical antimicrobial therapy was associated to a 2-fold decrease in survival at two years.
