As of now the relationship between glycocalyx degradation and microcirculatory perfusion abnormalities in non-septic critical ill patients is unclear. In addition, conjunctival sidestream dark field-imaging for the purpose of glycocalyx thickness estimation has never been performed. We aimed to investigate whether changes in glycocalyx thickness in non-septic patients are associated with microcirculatory alterations in conjunctival and sublingual mucosa. In this single-centre prospective observational study, using techniques for direct in-vivo observation of the microcirculation, we performed a single measurement of microcirculatory perfusion parameters and visualized glycocalyx thickness in both ocular conjunctiva and sublingual mucosa in mixed cardio surgical (n = 18) and neurocritical patients (n = 27) and compared these data with age-matched healthy controls (n = 20)...

BACKGROUND: Transfusion therapy is associated with increased morbidity, mortality and costs. Conventional coagulation tests (CCT) are weak bleeding predictors, poorly reflecting coagulation in vivo. Thromboelastometry (ROTEM) provides early identification of coagulation disorders and can guide transfusion therapy by goals, reducing blood components transfusion. OBJECTIVE: The aim of this study is to describe coagulation profile of critically ill patients using ROTEM and evaluate the association between CCT and thromboelastometry...

Skeletal muscle weakness is common in the intensive care units (ICU). Approximately 50% of patients under mechanical ventilation for more than 7 days show signs of ICU-acquired muscle weakness. In these patients, muscle weakness may be the result of axonal polyneuropathy, myopathy or a combination of both. The commonest risk factors in patients with ICU-acquired weakness (AW) are the severity and duration of the systemic inflammatory response, duration of the stay in the ICU and of mechanical ventilation, hyperglycemia, hypoalbuminemia, parenteral nutrition, and administration of corticosteroids and of neuromuscular blocking agents...

Acute kidney injury (AKI) is a common complication in critically ill patients and is associated with a worse short- and long-term outcome. The KDIGO (Kidney Disease: Improving Global Outcomes) guidelines suggest to implement preventive strategies in high-risk patients. Definition and classification of acute kidney injury according to the KDIGO criteria are based on an increase in serum creatinine and/or a decrease in urinary output. Renal replacement therapy (RRT) is the only supportive measure in patients with severe AKI...

The decrease in mortality in critical patient units led to an increase in intensive care unit acquired weakness (ICUAW), which significantly affects the functional performance and quality of life of patients. There are several scales that measure functionality in critical patients. The aim of this systematic review is to determine the criterion validity and reliability of the scales that evaluate functionality in critically ill adult patients. We considered studies in critically ill adult subjects of both genders that determined the psychometric properties of the scales that evaluate functionality...

INTRODUCTION: Respiratory muscle dysfunction, being a common cause of weaning failure, is strongly associated with prolonged mechanical ventilation (MV) and prolonged stay in intensive care units. Inspiratory muscle training (IMT) has been described as an important contributor to the treatment of respiratory muscle dysfunction in critically ill patients. Its effectiveness is however yet controversial. OBJECTIVE: To discuss evidence for assessment of readiness and the effectiveness of interventions for liberation from MV, with special attention to the role of IMT...

In the last decades, mortality from severe acute illnesses has considerably declined thanks to the advances in intensive care medicine. Meanwhile, critical care physicians realized that lifesustaining treatments (LST) may not be appropriate for every patient, and end-of-life care in the Intensive Care Unit (ICU) started to receive growing attention. Most deaths occurring in the ICU now follow a decision to forgo life-sustaining treatments (DFLST), which can be implemented either by withdrawing (WDLST) or withholding (WHLST) life-sustaining treatments...

PURPOSE OF REVIEW: The increasing incidence of acute kidney injury has the immediate effect of a growing need for renal replacement therapy (RRT). Shedding light on the questions of who, when, why, and how RRT should be performed is difficult to accomplish because of ambiguous study results, poor quality evidence, and low standardization. RECENT FINDINGS: Critically ill patients are exposed to multiple factors known to deteriorate kidney function. Especially severe fluid overload is strongly associated with worse outcome and may be considered as a trigger for initiating RRT...

As the demand for healthcare rises, so does the need for priority setting in healthcare. In this paper, I consider a prominent priority-setting principle: proportional shortfall. My purpose is to argue that proportional shortfall, as a principle, should not be adopted. My key criticism is that proportional shortfall fails to consider past health.Proportional shortfall is justified as it supposedly balances concern for prospective health while still accounting for lifetime health, even though past health is deemed irrelevant...

ICU-acquired weakness (ICUAW), including critical illness polyneuropathy, critical illness myopathy, and critical illness polyneuropathy and myopathy, is a frequent disabling disorder in ICU subjects. Research has predominantly been performed by intensivists, whose efforts have permitted the diagnosis of ICUAW early during an ICU stay and understanding of several of the pathophysiological and clinical aspects of this disorder. Despite important progress, the therapeutic strategies are unsatisfactory and issues such as functional outcomes and long-term recovery remain unclear...

Equalization of middle ear pressure is an important consideration for scuba divers. When middle ear pressure is asymmetric, a diver may experience alternobaric vertigo. Moreover, individuals with an underlying temporal bone dehiscence are predisposed to facial baroparesis. An understanding on behalf of fellow divers and emergency responders to recognize and differentiate facial baroparesis from decompression illness is critical. Misdiagnosis may lead to inappropriate treatment or unwarranted stoppage of diving...

Early mobilization is advocated to prevent intensive care unit-acquired physical weakness, but the patient's workload and its changes in response to body position changes have not been established. We used indirect calorimetry to determine the energy expenditure (EE) in response to body position changes, and we assessed EE's correlation with respiratory parameters in healthy volunteers: 8 males and 8 females, mean age 23.4±1.3 years. The subjects started in the resting supine position followed by a 30° head-up position, a 60° head-up position, an upright sitting position, a standing position, and the resting supine position...

BACKGROUND/AIMS: Blood pressure (BP) variability is associated with cardiovascular events, and cerebral and renal damage. The aim of this study was to investigate any potential relationship between short-term BP variability and incidence of acute onset conditions, such as acute kidney injury (AKI), in critically ill patients. METHODS: BP was monitored to analyze its variability in critically ill patients in present study. Short-term BP variability was assessed as average real variability (ARV), standard deviation (SD) and coefficient of variation (CV) of 24-hour BP...
