Haemodynamics and renal function following injection of bumetanide

Acta Medica Scandinavica

Abstract

Haemodynamics and renal function have been investigated in 12 patients with valvular heart disease before and after injection of 2 mg bumetanide in the right heart catheter. There were no significant changes in oxygen consumption, arteriovenous oxygen difference, cardiac index, heart beats per minute, stroke volume or right and left ventricular stroke work 35 min after the injection, whereas pulmonary and systemic arteriolar resistance showed a slight but insignificant reduction. Mean pulmonary capillary venous pressure, left ventricular end-diatolic pressure, mean pulmonary arterial pressure and mean pressure in the right atrium were highly significantly reduced after injection, systolic left ventricular pressure showing a significant but slight decrease. The creatinine and urea clearances increased considerably during the first 50 min after injection of bumetanide, but diminished during the second period to levels somewhat lower than the initial values. There was also a marked increase in the clearance of sodium potassium, calcium, magnisium and phosphate. It is concluded that bumetanide is a very potent diuretic which changes haemodynamic parameters towards normal values.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
