Observational Study
Role of circulating soluble chemokines in septic shock.
Chemokines are a large superfamily of small proteins that function not only in leukocyte trafficking, but are also necessary for linkage between innate and adaptive immunity. Little is known about their role in septic shock. We hypothesized that serum levels of the most important chemokines are related to organ failure, disease severity and outcome. ⋯ Upon admission to the ICU, IL-8 is a reliable biomarker of sepsis-induced AFR, ARDS and coagulopathy. Altered circulating MIP-1α and RANTES levels are also found in patients with septic shock and coagulopathy. However, chemokines do not appear to be good biomarkers of mortality in septic shock.

Practice Guideline
Clinical practice guidelines for evidence-based management of sedoanalgesia in critically ill adult patients.
Optimal management of sedation, analgesia and delirium offers comfort and security for the critical care patient, allows support measures to be applied more easily and enables an integral approach of medical care, at the same time that lowers the incidence of complications, wich translates in better patient outcomes. ⋯ This Guidelines contains recommendations and suggestions based on the best evidence available for the management of sedation, analgesia and delirium of the critically ill patient, including a bundle of strategies that serves this purpose. We highlight the assessment of pain and agitation/sedation through validated scales, the use of opioids initially to apropiate analgesic control, associated with multimodal strategies in order to reduce opioide consumption; to promote the lowest level of sedation necessary avoiding over-sedation. Also, in case of the need of sedatives, choose the most appropiate for the patient needs, avoiding the use of benzodiazepines and identify risk factors for delirium, in order to prevent its occurrence, diagnose delirium and treat it with the most suitable pharmacological agent, whether it is haloperidol, atypical antipsychotics or dexmedetomidine, once again, avoiding the use of benzodiazepines and decreasing the use of opioids.

To analyze the readability of informed consent documents (IC) used in an intensive care department and in the Andalusian Healthcare System (AHS). ⋯ The documents analyzed are generally difficult to read and understand by most people, and do not satisfy the basic purpose for which they were drafted.

Mitochondrial and microcirculatory distress syndrome (MMDS) can occur during systemic inflammatory response syndrome (SIRS), and is characterized by cytopathic tissue hypoxia uncorrected by oxygen transport optimization, and associated with an acquired defect in the use of oxygen and energy production in mitochondria, leading to multiple organ dysfunction (MOD). We examine the pathogenesis of MMDS, new diagnostic methods, and recent therapeutic approaches adapted to each of the three phases in the evolution of the syndrome. ⋯ Once the latter is established, the aim is to restore flow of the electron chain, mitochondrial respiration, and to avoid cellular energy collapse. Finally, in the third (resolution) stage, treatment should focus on stimulating mitochondrial biogenesis and the repair or replacement of damaged mitochondria.

Observational Study
Ten-year evolution of mechanical ventilation in acute respiratory failure in the hematogical patient admitted to the intensive care unit.
A comparison was made between invasive mechanical ventilation (IMV) and noninvasive positive pressure ventilation (NPPV) in haematological patients with acute respiratory failure. ⋯ The use of NPPV reduced mortality compared with IMV. NPPV failure was associated with more complications.
