The role of bicarbonate reabsorption and of transtubular chloride gradients in the bulk reabsorption of sodium and water by renal tubules can be tested in the isolated perfused kidney by perfusing with a medium from which bicarbonate has been omitted. Perfusion of the isolated rat kidney with an artificial medium in which bicarbonate is replaced by chloride results in a fall in fractional reabs...

CONTEXT Contrast-induced nephropathy remains a common complication of radiographic procedures. Pretreatment with sodium bicarbonate is more protective than sodium chloride in animal models of acute ischemic renal failure. Acute renal failure from both ischemia and contrast are postulated to occur from free-radical injury. However, no studies in humans or animals have evaluated the efficacy of s...

This report aims to look at the role of Sodium bicarbonate as a potent Ergogenic aid and its role in improving the performance of athletes. It includes the mechanism of action of sodium bicarbonate during high-intensity exercise. The report also shows the various types of athletes who can be benefited from sodium bicarbonate loading, evidences for improvement in performance, conflicting evidenc...

This report attempts to frame the debate about clinical administration of sodium bicarbonate in the setting of lactic acidosis in terms of simple questions. Specifically, we address why we develop lactic acidosis in some circumstances, how acute lactic acidosis impairs cardiovascular function and why sodium bicarbonate may have deleterious effects which limit its utility. We also attempt to exp...

BACKGROUND Vascular access in children carries a significant risk of accidental extravasation of IV fluids and medications with the potential for tissue injury. In this prospective controlled study we assessed the diagnostic utility of using IV diluted sodium bicarbonate to confirm placement of IV catheters in ventilated children. Diluted sodium bicarbonate was created using undiluted standard ...

BACKGROUND The regulation of fibroblast growth factor-23 (FGF23) secretion in patients with chronic kidney disease (CKD) is incompletely understood. An in vitro study showed that metabolic acidosis increased FGF23 in mouse bone. The objective of this study is to evaluate the effect of oral sodium bicarbonate on circulating FGF23 levels in patients with CKD. METHODS This was a single-blind pil...

Lactic acidosis often challenges the intensivist and is associated with a strikingly high mortality. Treatment involves discerning and correcting its underlying cause, ensuring adequate oxygen delivery to tissues, reducing oxygen demand through sedation and mechanical ventilation, and (most controversially) attempting to alkalinize the blood with IV sodium bicarbonate. Here we review the litera...

Sodium bicarbonate is administered during cardiopulmonary resuscitation (CPR) for the treatment of systemic acidemia. However, the effect of administering standard-dose sodium bicarbonate on the vasopressor effect of epinephrine is unknown. This study compared the effects of sodium bicarbonate or normal saline on the vasopressor effect of epinephrine in 18 pigs. After 10 minutes of unassisted v...
