Cognitive dysfunction is common in critically ill patients, not only during the acute illness but also long after its resolution. A large number of pathophysiologic mechanisms are thought to underlie critical illness-associated cognitive dysfunction, including neuro-transmitter abnormalities and occult diffuse brain injury. Markers that could be used to evaluate the influence of specific mechan...

Corresponding author: Hyeong Kyu Park Department of Internal Medicine, Soonchunhyang University Hospital, Soonchunhyang University College of Medicine, 59 Daesagwan-ro, Yongsan-gu, Seoul 140-743, Korea E-mail: [email protected] Critical illness is associated with a high risk for multiple organ failure and mortality. Hyperglycemia is common in critically ill patients and is related to adverse o...

Sleep and circadian rhythm are reported to be severely abnormal in critically ill patients. Disturbed sleep can lead to the development of delirium and, as a result, can be associated with prolonged stay in the intensive care unit (ICU) and increased mortality. The standard criterion method of sleep assessment, polysomnography (PSG), is complicated in critically ill patients due to the practica...

PURPOSE OF REVIEW Ongoing and severe systemic inflammation affecting critically ill patients may cause adrenal insufficiency and steroid resistance in target cells. As the appropriate diagnosis of this clinical entity remains a challenge, indication and practical use of corticosteroid replacement therapy in the critically ill is generally directed by clinical symptoms and features. RECENT FIN...

Infectious diseases and impaired renal function often occur in critically ill patients, and delaying the start of appropriate empiric antimicrobial therapy or starting inappropriate therapy has been associated with poor outcomes. Our primary objective was to critically review and discuss the influence of chronic kidney disease (CKD) and acute kidney injury (AKI) on the clinical pharmacokinetic ...

BACKGROUND Many critically ill patients experience moderate to severe acute pain that is frequently undetected and/or undertreated. Acute pain in this patient cohort not only derives from their injury and/or illness, but also as a consequence of delivering care whilst stabilising the patient. Emergency nurses are increasingly responsible for the safety and wellbeing of critically ill patients, ...

Prolonged critical illness has a high morbidity and mortality. The acute and chronic phases of critical illness are associated with distinct endocrine alterations. The acute neuroendocrine response to critical illness involves an activated anterior pituitary function. In prolonged critical illness, however, a reduced pulsatile secretion of anterior pituitary hormones and the so-called "wasting ...

ective dose of enoxaparin for thromboprophylaxis in critically ill patients recorded over 24 hours. Th e study concluded that the standard dose of 40 mg led to subtherapeutic anti-factor Xa activity (aFXa) and 60 mg daily was optimal. Th e high rate of thromboembolic disease observed in critically ill patients could thus be explained by inadequate aFXa with the standard 40 mg dose. Low molecula...

OBJECTIVE Vitamin D influences cardiovascular and immune function. We aimed to establish the prevalence of vitamin D deficiency in critically ill children and identify factors influencing admission 25-hydroxy vitamin D (25(OH)D) levels. We hypothesized that levels would be lower with increased illness severity and in children with serious infections. METHODS Participants were 511 severely or ...
