In the neurocritical care setting, hyponatremia is the commonest electrolyte disorder, which is associated with significant morbimortality. Cerebral salt wasting and syndrome of inappropriate antidiuretic hormone have been classically described as the 2 most frequent entities responsible of hyponatremia in neurocritical care patients. Nevertheless, to distinguish between both syndromes is usually difficult and useless as volume status is difficult to be determined, underlying pathophysiological mechanisms are still not fully understood, fluid restriction is usually contraindicated in these patients, and the first option in the therapeutic strategy is always the same: 3% hypertonic saline solution. Therefore, we definitively agree with the current concept of “cerebral salt wasting”, which means that whatever is the etiology of hyponatremia, initially in neurocritical care patients the treatment will be the same: hypertonic saline solution.

The high incidence of trauma, especially in elderly people anticoagulated with new oral anticoagulants (NOAs), has become a major challenge, particularly in critical situations with life-threatening bleeding. Under these circumstances, urgent NOA reversion becomes mandatory. Prothrombin complex has become a frequent indication in critical situations in which rapid reversal of anticoagulation is needed and where the use of fresh frozen plasma is limited. This study offers our point of view regarding the usefulness of NOAs, not only in the prevention of cardioembolic events but also as regards their emergent reversion in cases of severe bleeding associated to trauma.

OBJECTIVE: Some studies suggest that open access articles are more often cited than non-open access articles. However, the relationship between open access and citations count in a discipline such as intensive care medicine has not been studied to date. The present article analyzes the effect of open access publishing of scientific articles in intensive care medicine journals in terms of citations count. METHODS: We evaluated a total of 161 articles (76% being non-open access articles) published in Intensive Care Medicine in the year 2008. Citation data were compared between the two groups up until April 30, 2011. Potentially confounding variables for citation counts were adjusted for in a linear multiple regression model. RESULTS: The median number (interquartile range) of citations of non-open access articles was 8 (4-12) versus 9 (6-18) in the case of open access articles (p=0.084). In the highest citation range (>8), the citation count was 13 (10-16) and 18 (13-21) (p=0.008), respectively. The mean follow-up was 37.5±3 months in both groups. In the 30-35 months after publication, the average number (mean±standard deviation) of citations per article per month of non-open access articles was 0.28±0.6 versus 0.38±0.7 in the case of open access articles (p=0.043). Independent factors for citation advantage were the Hirsch index of the first signing author (β=0.207; p=0.015) and open access status (β=3.618; p=0.006). CONCLUSIONS: Open access publishing and the Hirsch index of the first signing author increase the impact of scientific articles. The open access advantage is greater for the more highly cited articles, and appears in the 30-35 months after publication.

Medicines reconciliation plays a key role in patient safety. However, there is limited data available on how this process affects critically ill patients. In this study, we evaluate a program of reconciliation in critically ill patients conducted by the Intensive Care Unit’s (ICU) pharmacist.

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. It is therefore a very useful drug in patients who can be maintained on mechanical ventilation with these levels of sedation avoiding the deleterious effects of over or infrasedation. 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.

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.

OBJECTIVE: To determine the life-sustaining treatment limitation (LSTL) predisposition upon patient admission to the intensive care unit (ICU), the criteria upon which such predisposition is based, and whether these decisions are related to structural factors of the surveyed hospitals. DESIGN: A descriptive multicenter study was made in 2010, involving the conduction of a survey in 90 hospitals, with a view to documenting the usual practice referred to LSTL upon admission in these centers. SETTING: Spanish ICUs. INTERVENTION: Opinion survey. MAIN VARIABLES OF INTEREST: Type of hospital, number of hospital beds, ICU and semicritical patient beds, usual bed availability in the ICU, use of restrictive admission criteria, use of LSTL criteria upon admission, and type of criterion used to decide LSTL. RESULTS: A total of 43 (48%) hospitals participated in the study, with LSTL being a common practice in these centers (93%). LSTL was fundamentally decided on the basis of the presence of prior severe chronic disease (95%), observation of previously declared patient will (95%), prior functional limitation (85%), and qualitative futility of care (82%). Frequent ICU bed availability (77% of the hospitals) and the use of restrictive criteria (79% of the hospitals) were also associated to patient admission with LSTL. CONCLUSIONS: Admission to ICU with LSTL is a generalized practice in Spanish Hospitals. LSTL is decided based on physiological futility from an objective medical point of view, but also in observance of ethical and moral implications based on the qualitative futility of medical care.
