Key result
The pulsatile mode of the Terumo centrifugal pump did not exhibit adverse hematological effects but produced unsatisfactorily small pulse pressures (mean 20 mm Hg) due to cannula dumping.
Why the study?
Does the pulsatile flow mode of the Terumo Capiox centrifugal pump generate adequate pulse pressure without adverse hematological effects compared to nonpulsatile flow or other pulsatile devices in patients undergoing CABG?
Population
16 patients undergoing cardiopulmonary bypass for coronary artery bypass graft surgery.

Limits pulsatile Terumo pump use in CABG due to inadequate pressures; leaves open optimized cannulation for effective pulsatility.

Does the pulsatile flow mode of the Terumo Capiox centrifugal pump generate adequate pulse pressure without adverse hematological effects compared to nonpulsatile flow or other pulsatile devices in patients undergoing CABG?
The pulsatile mode of the Terumo centrifugal pump produces unsatisfactorily small pulse pressures in the femoral artery due to cannula damping, despite having no adverse hematological effects.
Nishida et al. (1997) conducted an observational in Coronary artery bypass graft (CABG) (n=16). Pulsatile flow mode of Terumo Capiox centrifugal pump vs. Nonpulsatile CPB, IABP, and Delphin pump was evaluated on Pulse pressure and hematological parameters (platelet count, free hemoglobin, beta-thromboglobulin). The pulsatile mode of the Terumo centrifugal pump did not exhibit adverse hematological effects but produced unsatisfactorily small pulse pressures (mean 20 mm Hg) due to cannula dumping.
