ABSTRACT
BACKGROUND: Blood transfusion is often performed to support successful brain surgery. In this study, we looked at two groups of surgery patients to analyze the transfusion requirements for patients undergoing brain surgery in our hospital. Group A patients received elective surgery, whereby blood products were prepared in advance, and Group B patients required emergency surgery which is often accompanied massive bleeding, and therefore adequate transfusion blood may not be available in advance. METHODS: During a one year period, patients who received brain surgery were classified as requiring either elective (Group A) or emergency (Group B) surgery. In each group, operation time and blood transfusion requirements were compared. RESULTS: Of the 35 total patients included in this study, 14 cases were Group A and 21 cases were group B. Average operation time was 4 hours and 13 minutes (253 minutes), and 2 hours and 50 minutes (170 minutes), respectively for Groups A and B. Red Blood Cell (RBC) transfusion was conducted in more than 90% of all patients. Average volume of RBC transfusion per operation was 2.5 units (Group A) and 3.1 units (Group B). Fresh frozen plasma (FFP) was transfused in 21% of Group A patients and in 38% of Group B patients. Platelet Concentrate (PC) was transfused in 19% of Group B patients, only. CONCLUSION: FFP and PC were more frequently transfused in patients who received emergency surgery than those who received elective surgery. Preparation of, not only RBC, but FFP and PC is required for emergency brain surgery. Therefore, efforts to retain adequate amounts of blood are needed to support emergency brain surgery.

PURPOSE: This study was done to investigate the effects of backrest elevation of 0 degree and 30 degrees that minimize the risk of increasing ICP when CVP is measured. METHODS: Subjects were sixty-four patients who stayed in the neurosurgical intensive care unit after brain surgery at two university-based hospitals. CVP, blood pressure, heart rate and ICP were measured along with position changes in order of backrest position with primary 30 degrees backrest position, 0 degree backrest position and secondary 30 degrees backrest position. For data analysis, one-group, repeated-measures analysis of variance design was used in SAS program. RESULTS: Backrest elevations from 0 degree to 30 degrees did not alter the CVP without increasing the ICP. Therefore, 30 degrees backrest position is a preventive position without increasing ICP. CONCLUSION: 30 degrees backrest position might be appropriate for brain injury patients when CVP is measured.

90%, respectively. Although some shape changed red blood cells were observed in the washed blood, discocytes were the dominant form, with the percentage of discocytes being (58.0 ? 8.0)%. A greater number of shape-changed red blood cells were found in 2-week-old banked RBCs (P
