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...

COMMENT
John R Klinck, Lisa McNeill, David K Menon
Marked dysnatremia is associated with increased mortality in patients admitted to intensive care. However, new evidence suggests that even mild deviations from normal and simple variability of sodium values may also be significant. Should these findings prompt clinicians to re-evaluate the approach to fluid management in this setting? Sodium disorders, on one hand, are known to result from overzealous administration or restriction of free water or sodium ions. However, they are also associated with a range of co-morbidities and drug treatments that alter water loss and sodium handling in the nephron independently of prescribed fluid regimens...

Hypomagnesaemia is common finding in current medical practice mainly in critically ill, post-operative patients and patients admitted to ICU in tertiary cancer cases. Magnesium has been directly implicated in hypokalemia, hypocalcaemia and dysrrthymias. We report a case of 60 year old patient, suffering from rectal carcinoma for a period of one year with confirmed hypokalemia, hypocalcaemia and hyponatremia. Magnesium supplementation corrected the underlying multiple electrolyte disturbances in the patient thus, establishing a positive correlation of magnesium with sodium, potassium and calcium...

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...

PURPOSE: Although intensive care unit (ICU) acquired sodium disturbances are common in critically ill patients, few studies have examined sodium disturbances in patients following cardiac surgery. The objective of this study was to describe the epidemiology of ICU-acquired hyponatremia and hypernatremia in patients following cardiac surgery. METHODS: We identified 6,727 adults (> or =18 yr) who were admitted consecutively to a regional cardiovascular intensive care unit (CVICU) from January 1, 2000 to December 31, 2006 and were documented as having normal serum sodium levels (133 to 145 mmol...

BACKGROUND: Polyethylene glycol-based bowel preparations (PEGBPs) are widely perceived as safe and effective alternatives to oral sodium phosphate for bowel cleansing prior to colonoscopy. Most studies supporting this belief involve young patients with few comorbidities. OBJECTIVE: To characterize the incidence of electrolyte disturbances following PEGBPs administered prior to colonoscopy among elderly inpatients and hypothesize that PEGBP would be associated with hypokalemia in this setting...

INTRODUCTION: Although sodium disturbances are common in hospitalised patients, few studies have specifically investigated the epidemiology of sodium disturbances in the intensive care unit (ICU). The objectives of this study were to describe the incidence of ICU-acquired hyponatraemia and hypernatraemia and assess their effects on outcome in the ICU. METHODS: We identified 8142 consecutive adults (18 years of age or older) admitted to three medical-surgical ICUs between 1 January 2000 and 31 December 2006 who were documented to have normal serum sodium levels (133 to 145 mmol/L) during the first day of ICU admission...

BACKGROUND AND OBJECTIVE: Stewart's and Fencl's methods have recently been proposed to interpret acid-base disorders where traditional theory has proven inadequate. Our objectives were to evaluate: (1) the occurrence of acid-base disturbances in critically ill patients and their trend over the first 3 intensive care unit days, (2) whether Stewart's theory offers advantages over the traditional theory in the diagnosis of acid-base metabolic disturbances and (3) whether variables derived from Stewart's and Fencl's methods offer advantages over the traditional method to predict patient mortality...

Management of critically ill patients regularly involves the treatment of water and electrolyte disturbances. Moreover, critical care itself may contribute to volume overload and electrolyte abnormalities. Initial therapy should be followed by consequent diagnostic evaluation. The shift of volume and potassium in severe pancreatitis, for example, may lead to a life-threatening situation. In brain-dead patients, successful organ donation is facilitated by careful maintenance of water and electrolyte homeostasis...

BACKGROUND: The intensive care unit is a dynamic environment, where high numbers of patients cared for by health care workers of different experiences and backgrounds might result in great variability in patient care. Protocol-driven interventions may facilitate timely and uniform care of common problems, like electrolyte disturbances. We prospectively compared protocol-driven (PRD) vs. physician-driven (PHD) electrolyte replacement in adult critically ill patients. PATIENTS AND METHODS: In the first month of the two-month study, potassium, magnesium, and phosphate levels were checked by a physician before ordering replacement (PHD replacement period)...

We describe three critically ill patients who received drugs with K(ATP) channel-opening properties and subsequently developed severe life-threatening complications, including hyperkalaemia and cardiovascular disturbances. Administration of the sulfonylurea-receptor inhibitor glibenclamide promptly reversed these abnormalities. Over the past 3 years, we have seen this syndrome and response in five patients taking nicorandil, ciclosporin, or isoflurane, which suggests that this disorder arises more frequently than is currently realised...

Acid-base disturbances, such as metabolic or respiratory alkalosis, are relatively common in critically ill patients. We examined the effects of alkalosis (hypocapnic or metabolic alkalosis) on alveolar fluid reabsorption in the isolated and continuously perfused rat lung model. We found that alveolar fluid reabsorption after 1 hour was impaired by low levels of CO2 partial pressure (PCO2; 10 and 20 mm Hg) independent of pH levels (7.7 or 7.4). In addition, PCO2 higher than 30 mm Hg or metabolic alkalosis did not have an effect on this process...

Hypomagnesemia is the most common electrolyte disturbance seen upon admission to the intensive care unit (ICU). Reliable predictors of its occurrence are not described. The objective of this prospective study was to determine factors predictive of hypomagnesemia upon admission to the ICU. In a single tertiary cancer center, 226 patients with different diagnoses upon entering were studied. Hypomagnesemia was defined by serum levels <1.5 mg/dl. Demographic data, type of cancer, cause of admission, previous history of arrhythmia, cardiovascular disease, renal failure, drug administration (particularly diuretics, antiarrhythmics, chemotherapy and platinum compounds), previous nutrition intake and presence of hypovolemia were recorded for each patient...

Droperidol and haloperidol have demonstrated efficacy and safety in the treatment of acute delirium in critically ill patients. We conducted MEDLINE and manual searches of literature published from 1966-1996 to identify articles describing conduction disturbances associated with the drugs. The objectives were to describe the proposed mechanisms of acquired long QTc interval syndrome and torsades de pointes, and to recommend how critically ill patients receiving these agents should be monitored. We found 11 published reports of conduction disturbances associated with intravenous administration of droperidol or haloperidol...

A quantitative evaluation of metabolic acid-base component is described. The model is based on Stewart's analysis of acid-base chemistry. The metabolic component of acid-base disturbances is divided into four partial metabolic disorders; they can result from abnormal concentrations of chloride, albumin and phosphate disturbances, or from appearance of abnormal unidentified strong anions. The efficiency of the model is sufficient, quantitative partial results are given in the same units as base excess. In complex acid-base disturbances, such as are seen in critically ill patients, a detailed analysis of the specific components of the metabolic acid-base status allows one to plan specific therapeutic interventions...

Improved methods for monitoring and treating critically ill patients have increased the number of surgical candidates with multiorgan system impairment. Whereas such patients may have been considered "too sick to undergo surgery" in the past, many such patients linger in the intensive care unit unless definitive therapy is accomplished. Specific attention to review of the patient's preoperative preparation for surgery on a system-by-system basis may improve outcome substantially. The need for possible mechanical ventilation prior to transport to the operating room must receive particular attention...
