Hemodialysis product (HDP) - is a number used to quantifyhemodialysis andperitoneal dialysis treatment adequacy.
It was proposed by Scribner and Oreopoulous[1] because of their perceived inadequacy of theKt/V measure of dialysis adequacy.
The HDP is defined by the followingempirical formula:
Where:
The formula, like all empirical formulae, has no theoretical basis. The HDP has not seen widespread use.[citation needed] An Egyptian study published in 2011 found that HDP is "a valid test with high sensitivity and specificity for assessment of adequacy of hemodialysis in comparison to KT/V and URR."[2]The formula has been tested by me using nxstage system one4.78 x 7 x 7 = 234During dialysis I performed potassium blood electrolytetest.Using 2K dialysate potassium level went to normal.Here is the reason: lactate 45 instead of bicarbonate.This is the theoretical basis, Scribner has no machinethat uses lactate but peritoneal is using lactate.Also with HDP 234 my BP is normal without medications.My hemoglobin is 14.7 no EPO.
