OBJECTIVE
To investigate the impact of cardiopulmonary bypass (CPB) on free amino acid spectrum in plasma for patients with prosthetic valve replacement.
METHODS
The concentrations of the free amino acid in plasma for 22 patients with prosthetic valve replacement were measured with pre-column derivatization of high-performance liquid chromatography.
RESULTS
Compared with the preoperative data, the concentrations of some free amino acid in plasma decreased after the operation of cardiopulmonary bypass (CPB), especially some of the glucogenic amino acid and branch chain amino acid decreased significantly (P<0.05).
CONCLUSION
The operation of cardiopulmonary bypass (CPB) can decrease the concentrations of some free amino acid in plasma for patients with prosthetic valve replacement. It is essential to give these patients proper nutrition support during perioperative period.
