BACKGROUND: Atrial fibrillation is a common rhythm disturbance in the general medical-surgical intensive care unit. Amiodarone is a popular drug in this setting but evidence to inform clinical practice remains scarce. We aimed to identify whether variation in the clinical use of amiodarone was associated with recurrent atrial fibrillation. METHODS: This was a retrospective audit of 177 critically ill patients who developed new-onset atrial fibrillation after admission to a tertiary level medical-surgical trauma intensive care unit...

BACKGROUND: Thiamine plays a critical role in energy metabolism. Critically ill patients may have thiamine deficiency and increased mortality due to potentially irreversible consequences. The aim of this study was to show the impact of thiamine deficiency in a series of patients and the rapid response to thiamine replacement, showing the changes in clinical and metabolic conditions over time. METHODS: We described 3 cases of hospitalized patients who had received parenteral nutrition (PN) without vitamin supplementation...

INTRODUCTION: Extracorporeal membrane oxygenation (ECMO) is used in critically ill patients presenting acute cardiac and/or pulmonary dysfunctions, who are at high risk of developing acute kidney injury and fluid overload. Continuous renal replacement therapy (CRRT) is commonly used in intensive care units (ICU) to provide renal replacement and fluid management. We conducted a review to assess the feasibility, efficacy and safety of the combination of ECMO and CRRT and to illustrate the indications and methodology of providing renal replacement therapy during the ECMO procedure...

CONTEXT: The acute phase of the nonthyroidal illness syndrome (NTIS) is characterized by low T3 and high rT3 levels, affecting up to 75% of critically ill patients. Oxidative stress has been implicated as a causative factor of the disturbed peripheral thyroid hormone metabolism. OBJECTIVE: The objective of the study was to investigate whether N-acetylcysteine (NAC), a potent intracellular antioxidant, can prevent NTIS in patients with acute myocardial infarction...

IMPORTANCE: Intensive care unit (ICU)-acquired muscle wasting is a devastating complication leading to persistent weakness and functional disability. The mechanisms of this myopathy are unclear, but a disturbed balance of myosin heavy chain (MyHC) is implicated. OBJECTIVE: To investigate pathways of myosin turnover in severe critically ill patients at high risk of ICU-acquired weakness. DESIGN: Prospective, mechanistic, observational study...

REVIEW
Philip C Spinella, Allan Doctor
The philosophy of damage control resuscitation (DCR) and remote damage control resuscitation (RDCR) can be summarized by stating that the goal is to prevent death from hemorrhagic shock by "staying out of trouble instead of getting out of trouble." In other words, it is preferred to arrest the progression of shock, rather than also having to reverse this condition after significant tissue damage and organ injury cascades are established. Moreover, to prevent death from exsanguination, a balanced approach to the treatment of both shock and coagulopathy is required...

Disturbances in sodium concentration are common in the critically ill patient and associated with increased mortality. The key principle in treatment and prevention is that plasma [Na+] (P-[Na+]) is determined by external water and cation balances. P-[Na+] determines plasma tonicity. An important exception is hyperglycaemia, where P-[Na+] may be reduced despite plasma hypertonicity. The patient is first treated to secure airway, breathing and circulation to diminish secondary organ damage. Symptoms are critical when handling a patient with hyponatraemia...

Few organ systems are spared the progressive deterioration seen in critically ill patients with anorexia nervosa. Most of the endocrine disturbances discussed are due to starvation and represent appropriate metabolic adaptation of the body to food restriction and negative energy balance. In a starving patient, a lowered metabolic rate, increased cortisol and growth hormone level and reduced fertility are all appropriate adaptations to an abnormal and highly stressful state. Most metabolic abnormalities can be reversed with a well-planned refeeding program and nutritional recovery...

Electrolyte disturbances are frequently encountered in pediatric patients, not only in those with critical illness. They can manifest as lethargy, seizures, vomiting and cardiac arrhythmias. In many cases, electrolyte abnormalities are secondary to other underlying conditions, therefore clinical signs and symptoms can be predominated by the primary disease and not by the electrolyte imbalance. Clinical and laboratory evaluation must consist of a detailed history including any drug treatment, evaluation of volume status, acid-base balance, electrolytes as well as plasma and urine osmolality...

Cytokines interact with neurotransmitters and modify neuronal and neuroimmune functions. Intense in situ neuronal IL-2 immunoreactivity was detected in vital human brainstem neuronal centers which are principally implicated in cardio-respiratory control mechanisms. These observations were made in critically-ill aging adult as well as in young infant patients dying from various clinico-pathological conditions. We suggested that this in situ cytokine over-expression might tip a delicate balance in molecular interactions in those vital neuro-vegetative centers, causing disturbed homeostatic control of cardio-respiratory functions and impaired arousal responses; we further hypothesized that this IL-2-induced neuro-molecular disequilibrium in the brainstem microenvironment might thus be part of a final common pathway leading to death...

BACKGROUND: Sodium imbalance is common in-hospital electrolyte disturbance and is largely related to inequalities in water homeostasis. An important mechanism leading to dysnatraemic disorders is inadequately secreted plasma arginine vasopressin (AVP). Unfortunately, AVP measurement is cumbersome and not reliable. Copeptin is secreted in an equimolar ratio to AVP and is a promising marker in the differential diagnosis of hyponatraemia and possibly hypernatraemia in stable hospitalised patients...

Electrolyte imbalances are common in critically ill patients. Although multiple disease states typically encountered in the intensive care unit may be responsible for the development of electrolyte disorders, medications may contribute to these disturbances as well. Medications can interfere with the absorption of electrolytes, alter hormonal responses affecting homeostasis, as well as directly impact organ function responsible for maintaining electrolyte balance. The focus on this review is to identify commonly prescribed medications in the intensive care unit and potential electrolyte disturbances that may occur as a result of their use...

Hemostasis is an important intricately regulated homeostatic process. During the hospitalization a critically ill patient is often subjected to various external and internal stimuli which have abilities to influence the hemostasis. Administration of substitute solutions could be related to such an adverse effect. This paper tries to describe main mechanisms leading to impair the hemostatic balance during the fluid therapy and outline possibilities of their monitoring. The work also deals with every basic arteficial substitute solutions individually in term of their influence on coagulation...

Daniel L Chan
Colloids are increasingly becoming considered indispensable in the management of critically ill patients. Typical indications for colloid administration include patients with tissue edema, hypovolemia, and low oncotic pressure. Current guidelines for the use of colloids in veterinary patients balance the purported benefits of colloid fluid administration with the potential risks, such as volume overload and coagulation disturbances. This article focuses primarily on hydroxyethyl starches, because they are the most commonly used colloid in veterinary practice, and because recent advances in colloid therapy have been achieved with this colloid...

The reasons causing a patient to be hospitalized in the ICU, the degree of organs involvement and the subsequent therapeutic interventions, are all elements that can interfere with the acid-base homeostasis. It may be difficult to correctly evaluate the disturbances of the acid-base balance and to understand the underlying physiopathological process. Though, it is crucial to clarify the steps that resulted in the alteration, in order to increase the probability of detecting the correct diagnosis and therapy...
