A platelet count should be part of all post-cardiopulmonary bypass bleeding evaluations to detect functional significant platelet reduction and to provide a baseline to judge further dilutional reduction. This study provides data on platelet
counts
in
111 patients who used different oxygenators during the extracorporeal circulation. The patients were devided into 2 group(Group I : bubble type oxygenator, Group II : membrane type oxygenator), and they were measured in the changes of platelet
count,
hemoglobin and hematocrit levels before, during and after the extracorporeal circulation.
@ES The results were as follows:
@EN 1. Platelet counts began to decrease with the start of the extracorporeal circulation and continued to do until postoperative 5th days.
2. There were no significant differences of the platelet count and restoring time between the two types of oxygenator during the extracorporeal circulation.
3. Homoglobin and hematocrit levels were decreased with the start of the extracorporcal circulation. They have been restored to the normal value after the end of the extracorporeal circulation. There, however, were no significant differences
between to
the types of oxygenator.
Above results reveals that the types of oxygenator don't change of platelet count, hemoglobin, and hematocrit, so we can choose the types of oxygenator during the extracorporeal circulation according to facility and economy.
