REVIEW
K T Ng, J L L Yap
Loop diuretics remain a fundamental pharmacological therapy to remove excess fluid and improve symptom control in acute decompensated heart failure. Several recent randomised controlled trials have examined the clinical benefit of continuous vs. bolus furosemide in acute decompensated heart failure, but have reported conflicting findings. The aim of this review was to compare the effects of continuous and bolus furosemide with regard to mortality, length of hospital stay and its efficacy profile in acute decompensated heart failure...

Barbiturate coma therapy (BCT) is a treatment option that is used for refractory intracranial hypertension after all other options have been exhausted. Although BCT is a brain protection treatment, it also has several side effects such as hypotension, hepatic dysfunction, renal dysfunction, respiratory complications and electrolyte imbalances. One less concerning but potentially life-threatening complication of BCT is dyskalaemia. This complication could present as severe refractory hypokalaemia during the therapy with subsequent rebound hyperkalaemia after cessation of the therapy...

Hypertension is a common cardiovascular risk factor leading to heart failure (HF), coronary artery disease, stroke, peripheral artery disease and chronic renal insufficiency. Hypertensive heart disease can manifest as many cardiac arrhythmias, most commonly being atrial fibrillation (AF). Both supraventricular and ventricular arrhythmias may occur in hypertensive patients, especially in those with left ventricular hypertrophy (LVH) or HF. Also, some of the antihypertensive drugs commonly used to reduce blood pressure, such as thiazide diuretics, may result in electrolyte abnormalities (e...

OBJECTIVES: To determine the impact of the intensity of early correction of hyperglycaemia on outcomes in patients with diabetic ketoacidosis (DKA) admitted to the intensive care unit. METHODS: We studied adult patients with DKA admitted to 171 ICUs in Australia and New Zealand from 2000 to 2013. We used their blood glucose levels (BGLs) in the first 24 hours after ICU admission to determine whether intensive early correction of hyperglycemia to ≤ 180 mg/dL was independently associated with hypoglycaemia, hypokalaemia, hypo-osmolarity or mortality, compared with partial early correction to > 180 mg/dL as recommended by DKA-specific guidelines...

Hypokalaemic periodic paralysis is a rare skeletal muscle channelopathy causing flaccid paralysis, which predominantly presents in adolescents and young adults. I report a case of a 33-year-old Caucasian man who presented with sudden onset paralysis, following previous similar presentations without investigation. Blood tests revealed undetectable serum potassium levels in the context of paralysis. Other causes of hypokalaemia were excluded, and the patient was treated with planned lifelong prophylactic potassium replacement for a diagnosis of primary hypokalaemic periodic paralysis...

We report a case of a 9-year-old boy who developed hypokalaemic periodic paralysis (HypoPP) following a prodrome of persistent fatigue and muscle aches associated with mildly elevated creatine kinase (CK) levels.HypoPP is usually associated with a sudden onset of weakness and hypokalaemia at presentation. A review of published cases failed to identify any other reports of individuals with a similar onset of symptoms and elevated CK levels prior to the development of frank HypoPP.In the case described above, the association of these symptoms with elevated levels of CK may have been related to the underlying mutation in the skeletal muscle calcium channels that was subsequently identified...

A 31-year-old woman presented to the hospital with generalised weakness and lower back and abdominal pain. The only significant finding on physical examination was the weakness of the legs. Laboratory analysis in the emergency department revealed that she was hypokalaemic with metabolic acidosis. She was treated with oral and intravenous potassium, which resolved her weakness. During the search for an explanation for her renal tubular acidosis, she said she was exposed to paint exposure while working on a friend's house...

Hypokalaemic paralysis covers a heterogeneous group of disorders caused either by an enhanced shift of potassium into the cells or following a significant renal or gastrointestinal loss of potassium. We present the case of a 48-year-old Caucasian man with paralysis of both upper and lower extremities. ECG showed sinus rhythm and characteristic changes of hypokalaemia with depression of the ST segment, prolonged QTc interval of 581ms and U waves seen as a small positive deflection at the T wave in the middle precordial leads...

BACKGROUND: The overall evidence base regarding delirium has been growing steadily over the past few decades. There has been considerable analysis of delirium concerning, for example, mechanically ventilated patients, patients in the general intensive care unit (ICU) setting, and patients with exclusively postoperative delirium. Nevertheless, there are few studies regarding delirium in a cardiovascular ICU (ICCU) setting and especially scarce literature about the particular features of delirium relating to patient age and gender...

In cardiac patients, life-threatening tachyarrhythmia is often precipitated by abnormal changes in ventricular repolarization and refractoriness. Repolarization abnormalities typically evolve as a consequence of impaired function of outward K(+) currents in cardiac myocytes, which may be caused by genetic defects or result from various acquired pathophysiological conditions, including electrical remodelling in cardiac disease, ion channel modulation by clinically used pharmacological agents, and systemic electrolyte disorders seen in heart failure, such as hypokalaemia...

We present the case of a 58-year-old woman who developed hypokalaemia and metabolic alkalosis 2 weeks after therapy with colistimethate sodium for the treatment of chronic lower limb ulcer infection by extensively drug-resistant (XDR) Pseudomonas aeruginosa. The metabolic changes observed resembled Bartter syndrome, a group of congenital disorders affecting the distal segments of the renal tubules. The metabolic abnormalities reversed spontaneously 6 days after drug discontinuation. Acquired forms of Bartter syndrome have been reported during courses of antibiotic therapy; however, to our knowledge, this is the first documented case associated with colistimethate therapy in an adult...

Acquired Gitelman's syndrome (GS) associated with Sjögren syndrome (SS) is rare. A 50-year-old woman was admitted to our department because of nausea, acratia and sicca complex. Laboratory tests after admission showed renal failure, hypokalaemia, metabolic alkalosis, hypomagnesaemia and hypocalciuria, all of which met the diagnostic criteria for GS. Diagnostic evaluation identified primary SS as the cause of the acquired GS. Light microscopy of the renal tissue from the patient showed severe membranoproliferative glomerunephritis and tubulointerstitial nephritis...

BACKGROUND: Sudden cardiac arrest (SCA) is a complex multifactorial event and most commonly caused by ventricular tachycardia/ fibrillation (VT/ VF). Some antihypertensive drugs could induce hypokalaemia or hyperkalaemia that may increase susceptibility to VT/VF and SCA. OBJECTIVE: To assess the association between different classes of antihypertensive drugs classified according to their potential impact on serum potassium levels and the occurrence of out-of-hospital cardiac arrest (OHCA) based on VT/VF...
