Beyond bicarbonate: complete acid-base assessment in patients receiving intermittent hemodialysis.
Background Acid-base assessments in hemodialysis patients have been limited almost entirely to measurements of total CO 2 concentration, and assumptions have been made about the presence of acid-base disorders. To gain a fuller understanding of the acid-base status of stable hemodialysis patients, we analyzed measurements of pCO 2 , pH and HCO 3 - obtained in a cohort of chronic stable hemodial...
متن کاملEffect of acid-base status in vivo on bicarbonate transport by rabbit renal tubules in vitro.
In previous studies, when rabbit cortical collecting ducts were studied under standard conditions in vitro, bicarbonate transport was conditioned by the acid-base status in vivo of the animals from which the tubules were obtained. The collecting ducts absorbed bicarbonate if the animals were acidotic (from ammonium chloride administration), but they secreted bicarbonate if the animals were alka...
متن کاملIndividualized bicarbonate concentrations in the peritoneal dialysis fluid to optimize acid-base status in CAPD patients.
BACKGROUND A large percentage of peritoneal dialysis (PD) patients being treated with standard lactate-containing solutions tend to have serum bicarbonate concentrations below or above the normal range. The inter-patient variability of serum bicarbonate is a result of many influences and it may be appropriate to adjust the bicarbonate concentration in the peritoneal dialysis fluid (PDF) to the ...
متن کاملEffects on acid-base status
SINCE the introduction of external cardiac massage the technique and results of cardiac resuscitation have received much attention, but less information is available on the effect of cardiac arrest on respiration and circulation. The authors, who provided a resuscitation service for a general hospital, were particularly interested in these aspects and in thirty-eight of the first 100 patients t...
متن کاملBicarbonate and the Renal Regulation of Acid Base Balance1
Under the usual circumstance of ingestion of an acid ash diet the normal individual is faced with a deficit of available base. Those stores of circulating bicarbonate which enter the glomerular filtrate along with other crystalloids of the plasma are carefully conserved; only minute amounts are lost in the urine. But when an alkaline ash diet is ingested or sodium bicarbonate is administered, s...
