Human serum albumin (HSA) has been used for a long time as a resuscitation fluid in critically ill patients. It is known to exert several important physiological and pharmacological functions. Among them, the antioxidant properties seem to be of paramount importance as they may be implied in the potential beneficial effects that have been observed in the critical care and hepatological settings. ⋯ Such chemical modifications can occur during bioprocesses and storage conditions of the commercial HSA solutions, resulting in heterogeneous solutions for infusion. In this review, we explore the mechanisms that are responsible for the specific antioxidant properties of HSA in its native form, chemically modified forms, and commercial formulations. To conclude, we discuss the implication of this recent literature for future clinical trials using albumin as a drug and for elucidating the effects of HSA infusion in critically ill patients.

Role of biomarkers in the management of antibiotic therapy: an expert panel review: I - currently available biomarkers for clinical use in acute infections.
In the context of worldwide increasing antimicrobial resistance, good antimicrobial prescribing in more needed than ever; unfortunately, information available to clinicians often are insufficient to rely on. Biomarkers might provide help for decision-making and improve antibiotic management. ⋯ Other promising biomarkers that may prove useful in the near future but need to undergo more extensive clinical testing include sTREM-1, suPAR, ProADM, and Presepsin. New approaches to biomarkers of infections include point-of-care testing and genomics.

Lactate clearance for death prediction in severe sepsis or septic shock patients during the first 24 hours in Intensive Care Unit: an observational study.
This study was design to investigate the prognostic value for death at day-28 of lactate course and lactate clearance during the first 24 hours in Intensive Care Unit (ICU), after initial resuscitation. ⋯ During the first 24 hr in the ICU, lactate clearance was the best parameter associated with 28-day mortality rate in septic patients. Protocol of lactate clearance-directed therapy should be considered in septic patients, even after the golden hours.

The pain, agitation, and delirium practice guidelines for adult critically ill patients: a post-publication perspective.
The recently published Clinical Practice Guidelines for the Management of Pain, Agitation, and Delirium in Adult Patients in the Intensive Care Unit differ from earlier guidelines in the following ways: literature searches were performed in eight databases by a professional librarian; psychometric validation of assessment scales was considered in their recommendation; discrepancies in recommendation votes by guideline panel members are available in online supplements; and all recommendations were made exclusively on the basis of evidence available until December of 2010. Pain recognition and management remains challenging in the critically ill. Patient outcomes improve with routine pain assessment, use of co-analgesics and administration as well as dose adjustment of opiates to patient needs. ⋯ Lighter or no sedation is beneficial, and interruption is desirable in patients who require deep sedation for specific pathologic states. Delirium screening is probably useful; no treatment modality can be unequivocally recommended, and the benefit of prophylaxis is established only for early mobilization. The details of these recommendations, as well as more recent publications that complement the guidelines, are provided in this commentary.

How caregivers view patient comfort and what they do to improve it: a French survey.
Intensive care unit (ICU) patients are exposed to many sources of discomfort. Most of these are related to the patient's condition, but ICU design or how care is organized also can contribute. The present survey was designed to describe the opinions of ICU caregivers on sources of patient discomfort and to determine how they were dealt with in practice. The architectural and organizational characteristics of ICUs also were analyzed in relation to patient comfort. ⋯ Results of this survey showed that ICUs are poorly equipped to ensure patient privacy and rest. Access by loved ones and their participation in care also is limited. The data also highlighted that some sources of discomfort are less often taken into account by caregivers, despite being considered to contribute significantly.
