[Sudden onset of EDTA-dependent pseudothrombocytopenia in a patient scheduled for open heart surgery].

A 60-year-old woman scheduled for mitral and aortic valve replacement had sudden onset of thrombocytopenia without clinical symptoms. The platelet count was found to decrease after the sampling. Microscopic examinations confirmed platelet aggregations.

[Hemoglobin levels and weight gain after coronary bypass grafting by use of intraoperative hemodilution and autologous blood transfusion].

We investigated the relationship between the degree of hemodilution during cardiopulmonary bypass (CPB) and weight gain after coronary bypass grafting by use of intraoperative hemodilution and autologous blood transfusion. There is no significant difference in weight gain between the higher hemoglobin group (Hb > or = 6 g.dl-1) and the lower hemoglobin group (Hb < 6 g.

[Problems in clinical use of intraarterial blood gas monitoring system, Paratrend 7].

We evaluated the intraarterial blood gas monitoring system Paratrend 7 in clinical use. One hundred and sixty six sensors used for patients receiving thoracic, open heart or great vessel surgery were tested for one year, prospectively. Sensors were inserted through a 20 G intraarterial cannula into the radial artery before operation and removed when they malfunctioned or seemed to be not necessary for patient management in critical care unit.
