Multicenter Study Observational Study
Analysis of neutrophil gelatinase-associated lipocalin in the critical patient.
To determine if NGAL value exceeding 150 ng/mL is a good diagnostic test for acute renal failure in critically ill patients. ⋯ A NGAL>150 ng/mL does not seem to be an excellent test for AKI in critically ill patients but is associated with a worse prognosis.

The medical indications of tracheostomy comprise the alleviation of upper airway obstruction; the prevention of laryngeal and upper airway damage due to prolonged translaryngeal intubation in patients subjected to prolonged mechanical ventilation; and the facilitation of airway access for the removal of secretions. Since 1985, percutaneous tracheostomy (PT) has gained widespread acceptance as a method for creating a surgical airway in patients requiring long-term mechanical ventilation. Since then, several comparative trials of PT and surgical tracheostomy have been conducted, and new techniques for PT have been developed. ⋯ Tracheostomy should be performed as soon as the need for prolonged intubation is identified. However a validated model for the prediction of prolonged mechanical ventilation is not available, and the timing of tracheostomy should be individualized. The present review analyzes the state of the art of PT in mechanically ventilated patients--this being regarded by many as the technique of choice in performing tracheostomy in critically ill patients.

Although several studies have established the association between antibiotics and Clostridium difficile infection (CDI), there is a lack of epidemiological studies on the incidence of CDI in European Intensive Care Units outside the context of infection outbreaks. The present study describes the incidence, patient characteristics, complications, and recurrence rates of CDI in a Spanish ICU. ⋯ Less than 1% of the patients admitted to a clinical-surgical ICU in a large teaching institution in Spain developed CDI. However, a high risk of recurrence/complications was associated with prolonged ICU stay.

Hemodynamic monitoring offers valuable information on cardiovascular performance in the critically ill, and has become a fundamental tool in the diagnostic approach and in the therapy guidance of those patients presenting with tissue hypoperfusion. From introduction of the pulmonary artery catheter to the latest less invasive technologies, hemodynamic monitoring has been surrounded by many questions regarding its usefulness and its ultimate impact on patient prognosis. The Cardiological Intensive Care and CPR Working Group (GTCIC-RCP) of the Spanish Society of Intensive Care and Coronary Units (SEMICYUC) has recently impulsed the development of an updating series in hemodynamic monitoring. Now, a final series of recommendations are presented in order to analyze essential issues in hemodynamics, with the purpose of becoming a useful tool for residents and critical care practitioners involved in the daily management of critically ill patients.

The new published guidelines of compartment syndrome are supposed to be a helpful tool in order to make decisions in patients with abdominal hypertension. From a surgical perspective of view, an important effort has been made in order to reach consensus in different phases in which there is no clear answer in evidence-based medicine. It is mandatory the use of a universal classification of open abdomen and there are three main concepts that must be observed: make a decompressive laparotomy when conservative measures have failed, attempt to closure the abdomen as soon as possible and the use of negative-pressure treatments that facilitates the management of an open abdomen. Although most of recommendations that have been delivered are not high grades, the present guide is an important assistant for the management of intra-abdominal hypertension and several lines of investigation are opened in order to answer the doubts that have been addressed.
