Moderate and extreme haemodilution in open-heart surgery: electrolytes, urea, creatinine and osmolality. 1979

P Lilleaasen, and O Stokke

Two different programs of treatment, called moderate and extreme haemodilution, respectively, have been compared in patients undergoing aortic valve replacement. Serum electrolytes, urea, creatinine and osmolatity were satisfactory in both groups during and after surgery. A substantial retention of sodium took place in the moderately diluted patients. The extreme group lost more potassium in the urine than the moderate one. A small post-operative rise in creatinine indicates a slight kidney damage in the moderate group. Increased serum urea following moderate dilution might partly be due to increased protein catabolism.

D011188	Potassium	An element in the alkali group of metals with an atomic symbol K, atomic number 19, and atomic weight 39.10. It is the chief cation in the intracellular fluid of muscle and other cells. Potassium ion is a strong electrolyte that plays a significant role in the regulation of fluid volume and maintenance of the WATER-ELECTROLYTE BALANCE.
