NCT01864395

Brief Summary

It is hypothesized that on-line modified ultrafiltration (MUFF) post-cardiopulmonary bypass will result in improved patient outcomes over the 12-hour post-operative period as compared to control and off-line MUFF.

Outcome Measures

Primary Outcomes (1)

  • Post-Operative Volume of Chest Tube Drainage

    Our primary outcome variable is the post-operative volume of chest tube drainage.

    12 hours

Secondary Outcomes (2)

  • Biochemical Variables

    12 hours

  • Clinical Variables

    12 hours

Study Arms (3)

Control (CF)

EXPERIMENTAL

Centrifugation Method (CF): currently used to separate whole blood into red blood cells (RBCs) and plasma components. The RBCs are washed with normal saline and re-infused into the patient, while the plasma portion is discarded.

Procedure: Centrifugation Method

Online MUF

EXPERIMENTAL

Online MUF: hemofilter is used online while the heart-lung machine is connected to the patient.

Procedure: Online MUF

Offline MUF

EXPERIMENTAL

Offline MUF: hemofilter is used offline when the heart-lung machine is not connected to the patient.

Procedure: Offline MUF

Interventions
