BACKGROUND Patients with infective endocarditis (IE) have an elevated risk of renal dysfunction because of extensive systemic inflammation and use of nephrotoxic antibiotics. In this randomized, placebo-controlled trial, we investigated whether perioperative sodium bicarbonate administration could attenuate postoperative renal dysfunction in patients with IE undergoing cardiac surgery. METHOD...

INTRODUCTION Cardiac-surgery-associated-acute-kidney-injury (CSA-AKI) is associated with increased morbidity and mortality. Recent data from patients undergoing on-pump coronary artery bypass grafting suggest that a perioperative infusion of sodium-bicarbonate may decrease the incidence of CSA-AKI. The present study aims to analyze the renoprotective effects of a 24h infusion of sodium-bicarbon...

A swine producer reported severe chemical skin burns and high death losses when a group of finisher pigs was exposed to a combination of hydrated lime and sodium bicarbonate. Hydrated lime, an alkalinizing agent commonly used in industry and agriculture, is derived from limestone. We report clinical and experimental evidence that sodium bicarbonate can intensify the caustic effects of this form...

Urinary inorganic phosphate excretion was studied before and during the administration of sodium bicarbonate and acetazolamide in dogs that were not given infusions of phosphate. The excretion fraction of filtered phosphate increased after sodium bicarbonate or acetazolamide was given. This phosphaturia was attributed to decreased tubular reabsorption of phosphate consequent to alkalinization o...

BACKGROUND Intravenously administered iodine-containing contrast medium (CM) is associated with the development of contrast-induced nephropathy (CIN). Data on the effectiveness of sodium bicarbonate therapy in the prevention of CIN are controversial. Furthermore, the incidence of and risk factors for CIN in intensive care unit (ICU) patients are poorly defined. We investigated the effectiveness...

OBJECTIVES To critically discuss the treatment of metabolic acidosis and the main mechanisms of disease associated with this disorder; and to describe controversial aspects related to the risks and benefits of using sodium bicarbonate and other therapies. SOURCES Review of PubMed/MEDLINE, LILACS and Cochrane Library databases for articles published between 1996 and 2006 using the following ke...

BACKGROUND There have been conflicting reports on the use of intravenous administration of sodium bicarbonate for prevention of contrast-induced acute kidney injury (CI-AKI). The aim of this study was to evaluate the use of sodium bicarbonate for prevention of CI-AKI. METHODS This is a symptomatic review and meta-analysis of prospectively randomized studies, abstracts and manuscripts, publish...

BACKGROUND Caffeine and sodium bicarbonate ingestion have been suggested to improve high-intensity intermittent exercise, but it is unclear if these ergogenic substances affect performance under provoked metabolic acidification. To study the effects of caffeine and sodium bicarbonate on intense intermittent exercise performance and metabolic markers under exercise-induced acidification, intense...

Background: Sodium bicarbonate serum therapy is used for compensation bicarbonate lost and increasing blood pH in metabolic acidosis caused by severe anemia in patient with glucose-6-phosphate dehydrogenase (G6PD) deficiency. The aim of present study was comparison the effect of serum therapy using two different serums (serum with bicarbonate and without bicarbonate) on some renal and hematolog...

BACKGROUND Optimal hydration measures to prevent contrast-induced nephropathy are controversial. STUDY DESIGN We conducted a systematic review and meta-analysis using the MEDLINE database (1966 to January 2008), EMBASE (January 2008), and abstracts from conference proceedings. SETTING & POPULATION Adult patients undergoing contrast procedures. SELECTION CRITERIA FOR STUDIES Randomized con...
