Hypokalaemia: Improving the investigation, management and therapeutic monitoring of hypokalaemic medical inpatients at a district general hospital
Hypokalaemia is prevalent in 20% of hospitalised patients. Furthermore, inadequate management of hypokalemia was identified in 24% of these patients. Associated with significant patient morbidity and mortality, the identification, investigation, and treatment of hypokalaemia was identified as an area for improvement in the management of medical inpatients. The project aims to measure the assess...
متن کاملHypokalaemia: an independent risk factor of Enterobacteriaceae peritonitis in CAPD patients.
BACKGROUND Hypokalaemia is a relatively common complication in uraemic patients undergoing continuous ambulatory peritoneal dialysis (CAPD). The hazards of hypokalaemia are multiple and have been correlated with patient morbidity and mortality. Whether it is associated with increased risk of peritonitis remains to be addressed. METHODS We retrospectively analysed our CAPD patients who had com...
متن کاملHypokalaemia and hyperkalaemia.
Disturbances in potassium homoeostasis presenting as low or high serum potassium are common, especially among hospitalised patients. Given the fact that untreated hypokalaemia or hyperkalaemia is associated with high morbidity and mortality, it is critical to recognise and treat these disorders promptly. In this article, normal potassium homoeostasis is reviewed initially and then a pathophysio...
متن کاملHyperventilation of pregnancy presenting with flaccid quadriparesis due to hypokalaemia secondary to respiratory alkalosis.
Hyperventilation in pregnancy is a cause of chronic respiratory alkalosis. Alkalosis either metabolic or respiratory may cause intracellular shift of potassium ions that may lead to hypokalaemia. However, the resultant hypokalaemia in respiratory alkalosis is usually mild and does not cause much clinical features. A five-months-pregnant female of the age 25 years presented with sudden onset fla...
متن کاملHypokalaemia and ventricular fibrillation in acute myocardial infarction.
Serum potassium concentrations obtained on admission to hospital were inversely related to the incidence of ventricular fibrillation in 289 women and 785 men with acute myocardial infarction, 92 of whom developed ventricular fibrillation. Hypokalaemia (serum potassium concentration less than or equal to 3.5 mmol/l) was found in 122 patients (11.4%). The incidence of ventricular fibrillation was...
