A method for the assessment and management of factors both causing and maintaining a primary metabolic alkalosis is presented. During a 2-year period 65 patients with metabolic alkalosis were treated with saline and potassium chloride infusions. In four patients the alkalosis was refractory and required additional therapy. An infusion of hydrochloric acid 0.12-0.24 mol/litre through a central v...

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...

Hypoproteinemia is a common disturbance in patients suffering from various diseases. It can be accompanied by hypovolemia and hypotension that influences the volume space of drugs in the body as well as the acid-base balance. In the present study, 22 patients with hypoproteinemia (8F, 14M) constituted group A. In this group the acid-base disorders as well as their importance were evaluated. Fro...

A 65-year-old comatose man with metastatic melanoma developed rapidly cycling breathing, clusters of approximately 10 abdominal excursions within 3 seconds, interspersed by seconds apnea (video 1 and figure), mimicking myoclonus. Introduced Plum Posner1 as a respiratory pattern associated lesions in the low pons or high medulla, cluster breathing can occur without pontomedullary when alkalosis ...

We report a patient with systemic lupus erythematosus (SLE), who had developed metabolic alkalosis during plasmapheresis. The metabolic alkalosis could be promptly corrected by reducing the amount of citrate load. The development of metabolic alkalosis can be explained by the citrate load during plasmapheresis. Careful monitoring of acid base status is mandatory in patients with limited renal f...

Intravenous infusion of hydrochloric acid was used as a safe, effective, and quantitative method for correction of metabolic alkalosis in two patients. The first shows the risks of intravenously administered ammonium chloride, the currently available alternative to hydrochloric acid therapy. The second shows the efficacy of intravenously administered hydrochloric acid. While breathing spontaneo...

We previously found that nitric oxide synthase (NOS) inhibition fully blocked alkalosis-induced relaxation of piglet pulmonary artery and vein rings. In contrast, NOS inhibition alone had no effect on alkalosis-induced pulmonary vasodilation in isolated piglet lungs. This study sought to identify factors contributing to the discordance between isolated and in situ pulmonary vessels. The roles o...

1. Five males were studied on three occasions, after oral administration of CaCO3 (control), NH4Cl (acidosis) and NaHCO3 (alkalosis), in a dose of 0.3 g/kg, taken over a 3 h period at rest. The subjects then exercised on a cycle ergometer for 20 min at 33% maximal oxygen uptake (VO2 max.), followed by 20 min at 66% and at 95% VO2 max. until exhaustion. 2. Endurance at 95% VO2 max. was longest w...
