hemoconcentration
Process of removing excess plasma water to increase hematocrit and blood component concentrations during CPB.
Full Definition
Hemoconcentration involves the removal of plasma water and small solutes from blood during cardiopulmonary bypass using ultrafiltration devices. This process increases hematocrit, plasma protein concentrations, and platelet counts while reducing total body water and inflammatory mediators. Hemoconcentration is particularly beneficial in pediatric cardiac surgery where hemodilution effects are more pronounced, and in procedures requiring blood conservation strategies.
Usage
Usage note: Distinguish from other blood processing techniques when documenting perfusion management.
