25 Patients were received major spinal surgeries at main operating theater of Kangnam General Hospital from May 1990 to December 1990 by using the Haemonetics cell saver which was employed as an intraoperative blood salvage and autologous blood transfuser. The products of washed red blood cells were an average of 1490 cc packed RBC per case. Under the Light Microscopy, Washed RBC disclosed the morphologies of normal RBC size and shape. Fragmented RBCs or cell debris were not found and in one case agglutinated and denaturated RBCs were seen. While 20 patients were received spinal surgery prior to the utilization of cell saver, an average of 7.85 units of banked whole blood was transfused compared with 5.55 units in the cases of using the cell saver (p<0.05). Homologous banked blood utilization during spinal surgery declined more than 30% with the use of the cell saver. There was no evidence of infection, renal and/or hepatic failure related to the use of the cell saver. Haemonetics cell saver appeared to be safe, efficient and more over in some instanes life saving.

OBJECTIVETo investigate the effects of acute hypervolemic hemodilution (AHH) and intraoperative blood salvage (IOBS) on the morphology and biomechanics of erythrocytes using atomic force microscopy (AFM).

METHODSBlood samples were collected from 20 patients undergoing orthopedic surgery before operation (T1), immediately after AHH (T2), and after blood salvage (T3). AFM at nanometer resolution was used to examine the morphology and biomechanics of the collected erythrocytes.

RESULTSThe blood samples collected at T1 showed a significantly lower ratio of heteromorphous erythrocytes than those collected at T2 and T3 [(2.6∓1.3)% vs (19.3∓1.6)% and (17.6∓1.4)%, P<0.05]. AFM revealed significant differences in the morphology and biomechanics of the single erythrocyte in salvaged blood and blood after AHH compared with those of venous blood.

CONCLUSIONAHH and IOBS may cause significant changes in the morphology and biomechanics of erythrocytes in the salvaged blood.

Increasingly, autologous blood transfusion has been arousing concern owing to awareness of adverse effects of allogenic blood transfusion, blood shortage and patients, having religious or personal issues. With the development of medicine, Cell Salvage and Acute normovolemic hemodilution (ANH) has been proposed as an alternative to allogenic blood transfusion. This review looked at the use of ANH and cell salvage and evaluated the benefits and usefulness based on the strengths and indications. Although not consistent with all cases of ANH, there were benefits in the amount of hemorrhage and transfusion, and no supplementary plasma or platelet transfusion was needed after surgery when employing ANH. But, it showed a cutoff value only for massive bleeding surgery (at least 500 mL). In the case of cell salvage, the amount of blood transfusion was reduced in most cases and platelet or plasma transfusion was not required in most cases. When the Leukoreduction filter (LDF) was utilized, it showed the effect of removing bacterial infection or tumor cells. Nonetheless, the effectiveness and benefits for patients in certain condition of cell salvage and ANH is ambiguous with discrepancies among studies or patients. Therefore, the aim of this study is to provide clinical knowledge relative to the procedure, measure the efficacy and usefulness of peri-operative blood management mentioned above and discuss the forthcoming prospects and challenges.

BACKGROUND: In the case of bilateral total knee replacement arthroplasty (TKA), surgery is performed either simultaneously or in a staged manner. We tried to investigate the differences of blood loss and transfusion practice between the use of simultaneous and staged operations. METHODS: We analyzed retrospectively the medical records of 20 patients undergoing simultaneous TKA (simultaneous group), who received autologous blood via a reinfusion system, and 20 patients undergoing staged TKA (staged group), of which the interval is about three weeks. We compared the amount of blood loss, and the number of transfusions and transfusion-related complications between the two groups of patients. RESULTS: Postoperative total blood loss was 2,174 +/- 460 ml in the simultaneous group and 1,850 +/- 461 ml in the staged group. There was no significant difference for transfusion (simultaneous group 3.5 +/- 1.1 units, staged group 3.9 +/- 1.4 units; P > 0.05). In the simultaneous group, the volume of autologous transfusion was 985 +/- 326 ml, corresponding to 2.5 +/- 0.8 units. The total number of transfused RBC units including autologous blood was 6.1 +/- 1.5 units in the simultaneous group and 3.9 +/- 1.4 units in the staged group. In the staged group, the amount of postoperative drained blood was significantly less in the second knee operation than that in the first knee operation (first knee surgery, 992 +/- 265 ml; second knee surgery, 868 +/- 260 ml: P < 0.05). CONCLUSIONS: Postoperative blood loss and total transfusion were less in the staged TKA group of patients as compared with the simultaneous TKA group of patients. Postoperative blood salvage and reinfusion appear to be safe and effective for patients undergoing simultaneous TKA.

Antibodies to high-incidence red blood cell antigens should be considered if panagglutination reactions are noted in all panel cells, and negative reactions to autologous red blood cells are detected on antibody screening and identification tests. In Korea, most of those antibodies are identified through international reference laboratories. To prevent a hemolytic transfusion reaction, antigen-negative red cells should be provided for those patients who have antibodies to red cell antigens. However, this is nearly impossible when the antibody has specificity to high-incidence red cell antigen. In those cases, transfusion of autologous blood, cryopreserved rare blood and the least incompatible blood components can be considered. In the case of surgery, acute normovolemic hemodilution or intraoperative blood salvage can also be considered. For the patients who have antibodies to high-incidence red cell antigens, it should be discussed to set up a national reference laboratory to quickly identify antibody specificities, and to consider establishing rare blood donor registry and frozen rare blood storage/supply system. This article reviews characteristics of antibodies to high-incidence antigens found in Koreans and also the transfusion experiences of those patients based on literature.

Liver transplantation is especially challenging in patients who are Jehovah's Witnesses because their religious beliefs prohibit the receipt of blood products. We present two cases of living donor liver transplantation performed in adult Jehovah's Witnesses in South Korea without the use of blood products. In the first case, preoperative erythropoiesisstimulation therapy increased hemoglobin levels from 8.1 to 13.1 g/dl after 9 weeks. In the second case, hemoglobin levels increased from 7.4 to 10.8 g/dl after 6 months of erythropoiesis-stimulation therapy. With the combination of acute normovolemic hemodilution, intraoperative cell salvage, and use of transfusion alternatives, liver transplantation was successfully performed without transfusion of blood products.

Preoperative anemia should be diagnosed and treated before surgery, because anemia is associated with increased postoperative mortality and morbidity. Even if iron deficiency is not detected, the possibility of functional iron deficiency should be considered. During surgery, patients should be managed to avoid hypothermia, acidosis, and hypocalcemia, while maintaining adequate blood pressure and preventing dilutional coagulopathy. It is currently recommended to start transfusion when hemoglobin is under 7–8 g/dL in patients without cardiac problems, using restrictive strategy rather than liberal, due to dangers of complications from transfusion. For those who refuse transfusion, or when transfusion is difficult due to multiple antibodies, or when attempting to reduce allogeneic transfusion, preoperative autologous blood donation (PAD), intraoperative acute normovolemic hemodilution (ANH), intraoperative blood salvage, or postoperative blood salvage can be used. For patients with trauma or massive bleeding, damage control resuscitation of permissive hypotension, restriction of crystalloid infusion, transfusion of blood product in a ratio similar to whole blood (1:1:1 of FFP, platelets, PRBC) must be actively carried out.

OBJECTIVE: Patient' desire of transfusion free surgery has been increasing due to blood transfusion risks. We analyzed the perioperative parameters and perioperative management of transfusion free surgical treatment in Soonchunhyang University Seoul Hospital. METHODS: Operation quantity and blood unstoring count from blood bank between 2000 and 2012 were collected from chronological records. Perioperative parameters including preoperative hemoglobin level, postoperative hemoglobin level, and lowest hemoglobin level were collected from medical records. Perioperative blood management such as acute normovolemic hemodilution, intraoperative blood cell salvage, or hematinic agents and complication were assessed. RESULTS: A total of 3,088 patients underwent transfusion free surgery at Soonchunhyang University Seoul Hospital between 2000 and 2012. Postoperative hemoglobin level <5.0 g/dL were 33 patients. Four patients expired at postoperative period with serious perioperative complications. Average of expired patient's hemoglobin was 3.22 g/dL and overall mortality was 0.12%. Operation was increased as years go by. The amount of blood use bank wasn't increased in general patients with transfusion. CONCLUSION: Careful perioperative blood management for transfusion free surgical treatment was responsible for safety and results in good clinical outcomes. Overall transfusion rate was decreased in spite of increasing operation quantity.

STUDY DESIGN: Prospective cohort study. PURPOSE: There has been no research examining the use of intraoperative cell salvage during metastatic spinal surgery. The present work is a pilot study investigating the role of cell salvage during metastatic spine surgery. OVERVIEW OF LITERATURE: There is no spinal literature about role of cell salvage and autologus transfusion in metastatic spinal cancer. METHODS: Sixteen spinal metastases patients who received red cell salvage using a leucocyte depletion filter were enrolled. Of these, ten patients who received salvaged blood transfusion were included in the final analysis. Data collection involved looking at the case notes, operating room records and the prospectively updated metastatic spinal cancer database maintained in the spinal department. Cell salvage data was recovered from the central cell salvage database maintained in the anesthetic department. RESULTS: Amount of salvaged blood ranged from 120 to 600 mL (average, 318 mL). The average drop in hemoglobin was 1.65 units (range, 0.4-2.7 units). Three patients (30%) required postoperative allogenic blood transfusion. The average follow up was 9.5 months (range, 6-6 months). One patient developed new lung metastasis, at seven months. No patient developed new liver metastases. Preoperatively, six patients had diffuse skeletal metastases. Of this subgroup, three developed new skeletal metastases. No cases showed any wound related problems in the postoperative period. CONCLUSIONS: In our study transfusion of intraoperatively salvaged blood did not result in disseminated metastatic cancer. We would suggest that red cell salvage might have a role during metastatic spine surgery.

We report the case of an 11-month-old Jehovah's Witness girl with end-stage liver disease secondary to biliary atresia who underwent a successful living-related liver transplantation. The donor was her mother who is a member of Jehovah's Witness. The use of recombinant human erythropoietin increased hemoglobin concentrations during the perioperative period. Intraoperatively, meticulous surgical hemostasis, avoidance of hypothermia, minimal blood sampling, administration of tranexamic acid, and return of the blood scavenged from the operative field by intraoperative blood salvage enabled the completion of the operation without the use of blood products.
