Key result
A rapid heparin assay allowed calculation of reduced protamine doses (nearly two-thirds of previous doses) without increased bleeding, clotting, or clinically significant heparin rebound.
Why the study?
Does a rapid heparin assay and calculated reduced protamine dose safely neutralize heparin without increased bleeding or clotting in patients undergoing cardiopulmonary bypass?
Population
Patients receiving common doses of heparin during cardiopulmonary bypass for open heart surgery
Comparison

Suggests rapid heparin assay may safely guide reduced protamine dosing in CPB; hypothesis-generating and requires randomized confirmation.

Does a rapid heparin assay and calculated reduced protamine dose safely neutralize heparin without increased bleeding or clotting in patients undergoing cardiopulmonary bypass?
A rapid heparin assay allows for accurate monitoring during cardiopulmonary bypass and calculation of reduced protamine doses that safely neutralize heparin without increasing bleeding or clotting risks.
Umlas et al. (1983) conducted an observational in Patients undergoing cardiopulmonary bypass during open heart surgery. Rapid heparin assay and calculated reduced protamine doses vs. Previous standard protamine doses was evaluated on Bleeding, clotting, or clinically significant heparin rebound. A rapid heparin assay allowed calculation of reduced protamine doses (nearly two-thirds of previous doses) without increased bleeding, clotting, or clinically significant heparin rebound.
