Diagnosis of metabolic acid-base disturbances in critically ill patients.
We compare two commonly used diagnostic approaches, one relying on plasma bicarbonate concentration and "anion gap," the other on "base excess," with a third method based on physicochemical principles, for their value in detecting complex metabolic acid-base disturbances. We analyzed arterial blood samples from 152 patients and nine normal subjects for pH, PCO(2), and concentrations of plasma e...
متن کاملAcid-base and metabolic disturbances in fulminant hepatic failure.
In 28 patients with fulminant hepatic failure alkalaemia was present in 49 of a total of 65 observations. Alkalaemia was due primarlily to a low Pa, C02 in 30 instances and to raised plasma bicarbonate in 16 instances. Blood lactate, pyruvate, and acetoacetate were significantly raised, and in individual cases, blood citrate, succinate, and fumarate were elevated. Blood citrate rose progressive...
متن کاملDisturbances in Acid-Base Balance in Patients on Hemodialysis
The prevalence of metabolic acidosis increases in Chronic Kidney Disease (CKD) patients ac‐ cording to the fall in glomerular filtration rate (GFR). In early stages of renal dysfunction acid retention is mainly due to the reduced tubular ammonium (NH4+) secretion. As GFR de‐ clines retention of organic acids (HSO4, HPO4) is also observed. The acid load resultant from diet and protein catabolism...
متن کاملThe Frequency of the Causes of Acid Base Disturbances in Patients Hospitalized in the Toxicology Ward of Baharloo Hospital in 2009
Background: The aim of this study was to evaluate the efficacy of arterial blood gases (ABGs) in determining the type of intoxication. Methods: Medical charts of all patients who had referred to the toxicology ward of Baharloo Hospital between January 2009 and December 2009 were evaluated. After excluding the patients with multi-drug toxicity, data, including age, sex, type of intoxication ...
متن کاملNeonatal acid-base disturbances.
The introduction of the micro-Astrup technique (Siggaard Andersen, Engel, J0rgensen, and Astrup, 1960) with the subsequent modification of the nomogram (Siggaard Andersen, 1962) has given a rapid and simple method for separating the respiratory and metabolic components of acid-base equilibrium in the blood. Arterialized capillary blood from a heel stab has been used for the estimation ofpH and ...
