Processing intra-operative blood loss by two different techniques does it affect the donor blood consumption?
A prospective randomized pilot study.

In the last years the Isala clinics have done a lot of work to reduce donor
blood consumption. One way to reduce donor blood consumption is to reduce blood
activation so that post-operative clotting occurs more quickly. Literature
describes that using a cell salvaging device for the process of cardiotomy
blood compared with cardiotmy blood given directly to the patient has a
beneficial effect on blood activation. Both techniques are used in the Isala
clinics.

This study will compare both techniques in or own clinical setting regarding to
donor blood consumption.

This pilot study compares two existing techniques to see if there's a differt
in donor blood consumption.

observational, prospective randomized study

The use of the cardiotomiesuction or not.

This study provides no additional harm or risk to the patients because it
compares two generally accepted, existing techniques that are routinely used.
Because both techniques are generally used and no additional blood samples or
actions are needed fot this study there will be no additional burden or risk
for the patient.
