Acid-base Balance in Acute Gastrointestinal Bleeding

Acid-base balance in acute gastrointestinal bleeding.

Acid-base balance has been studied in 21 patients with acute upper gastrointestinal bleeding. A low plasma bicarbonate concentration was found in nine patients, accompanied in each case by a base deficit of more than 3 mEq/litre, indicating a metabolic acidosis. Three patients had a low blood pH. Hyperlactataemia appeared to be a major cause of the acidosis. This was not accompanied by a raised...

How effective is tranexamic acid for acute gastrointestinal bleeding?

Medical Acid-base Balance

an increase in the number of poisonings occurring in the province or from an increase in the number of enquiries with no change in the number of poisonings. (ii) there was an increase in 1976 in the number of prescriptions dispensed and therefore an increase in the number of drugs consumed. (iii) the increase in enquiries about poisoning in children, if it reflects an increase in actual poisoni...

Acid-base Balance in Sweat

The reaction, the osmotic pressure, and the volume relationships of the body fluids are closely dependent on the properly regulated acid-base equilibrium. We have attempted to work out some of the regulatory mechanisms for the preservat.ion of acidbase equilibrium during the process of heavy sweating in ways analogous to those employed in the many similar studies of blood and urine. The changes...

Acute gastrointestinal bleeding: Part I.

OBJECTIVE To review the management of acute gastrointestinal bleeding in the critically ill patient in a two part presentation. DATA SOURCES Articles and a review of studies reported from 1991 to 2001 and identified through a MEDLINE search of the English language literature on acute gastrointestinal bleeding. SUMMARY OF REVIEW Gastrointestinal bleeding is a relatively frequent problem in t...
