Intraoperative Salvage in Open Heart Surgery

Ham, Byung Moon; Lee, Sang Min

Abstract

For autologous transfusion, intraoperative salvage technique with Cell Saver Apparatus was used in open heart surgery. Seventy-eight patients were involved in this study and divided into two groups. They were group of salvage(n=58) and non-salvage(n=20). In each group, they were also divided into four groups of CHD(who underwent surgery of congenital heart disease), UNDO(who underwent first-valvular surgery or repair of dissecting aneurysm), REDO(who underwent redo-valvular surgery) and CABG(who underwent coronary artery bypass surgery) according to the degree of blood loss during surgery. Amount of blood obtained from Cell Saver Apparatus was 811+/-273(mean+/-std) ml. Hematologic profile of blood from this apparatus was as follows, 1) Hemoglobin: 18.2+/-2.0(g/dl), 2) Hematocrit: 52.8+/-5.6(%), 3) Platelet: 35K+/-21K (mm). The hank blood utility ratio{No. of patients who used hank blood (No. of patients who used bank blood+who didnt use bank blood)x100(%)) tended to increase in non-salvage group and statistically significant(p< or =0.05) only in CHD group(non-salvage group vs. salvage group= 63% vs. 17%). And the amount of bank blood transfused tended to be higher in non-salvage group than salvage group and statistically significant(p< or =0.05) only in CHD group. This study suggested that intraoperative salvage technique with Cell Saver Apparatus could decrease the use of bank blood in open heart surgery.
