Abstract
Background: Red blood cells may be destroyed by autotransfusion processing during intraoperative salvage. The aim of the present study was to evaluate the blood component recovery rate of techniques built on either continuous centrifugation and washing, or haemofiltration (HF). Methods: Two different methods used in blood salvage - red cell salvage with continuous processing with centrifugation and saline washing (Continuous Auto Transfusion System, CATS) and whole blood recirculation through a 30000-Da filter, i.e., HF - were compared in a randomized laboratory study using donor whole blood activated by cobra venom factor. The recovery of red blood cells, haemoglobin, free haemoglobin, leucocytes, platelets, albumin, total protein and potassium was measured. Results: The recovery of red cells was 86% with CATS and 76% with HF. HF had a significantly higher recovery of leucocytes (CATS 20%, HF 63%), platelets (CATS 4%, HF 37%), albumin (CATS 0.2%, HF 70%), total protein (CATS 1.3%, HF 71%) and potassium (CATS 2%, HF 17%). Less than 1% haemolysis was obtained in processed blood from both groups. Conclusion: Both methods caused little destruction of the red blood cells during processing. There was a larger reinfusion of leucocytes, platelets, albumin, total protein and extracellular potassium when HF was used compared with the ‘CATS’ method.

Abstract
BACKGROUND AND OBJECTIVES Transfusion of autologous whole blood is one available method to reduce the need for allogenic blood transfusion. The objective of this study was to investigate the safety of transfusion of intra-operative autologous whole blood by monitoring plasma concentration of laboratory variables and adverse events after transfusion with the Sangvia(®) system. MATERIALS AND METHODS The clinical trial was designed as an open, prospective, multi-centre study, and a total of 20 patients undergoing primary hip arthroplasty were included. Systemic blood samples were taken and analysed preoperatively, at transfusion start and end and at 3, 6, 24 and 48 h after the transfusion. RESULTS Elevated values of complement activation and pro-inflammatory cytokines were seen in the intra-operatively collected blood but the impact on systemic levels were limited with low peak levels, systemic elevations before transfusion and normalization during the study period. Elevated levels of free haemoglobin and potassium were also detected in the intra-operatively collected blood, but systemic values were within reference values after the transfusion. No clinically relevant adverse event occurred during the study. CONCLUSION Inflammatory mediators and plasma haemoglobin were increased in intra-operatively salvaged and filtered blood compared to circulatory levels. Intra-operative retransfusion of autologous whole blood caused a transient systemic increase that normalized in the early postoperative period. There were no significant adverse events reported in the study. These data suggest that the Sangvia(®) system can be used for intra-operative collection and retransfusion of salvaged blood.

Abstract
BACKGROUND This study intends to prove the hypothesis that preoperative autologous blood donation in total knee arthroplasties (TKA) is dispensable. PATIENTS AND METHODS The study comprises a prospective analysis of 81 consecutive TKA without preoperative autologous blood donation (AB-donation). Guidelines for blood retransfusion were used. Surgery, as well as the pre- and postoperative procedures were identical for each patient. In the analysis of the data, the consecutive TKAs were divided into patients who were eligible for preoperative autologous blood donation (group 1, n = 46) and those with relevant risk factors not permitting preoperative autologous blood donation (group 2, n = 35). RESULTS None of the patients in group 1 needed a blood transfusion. 14 of 35 patients in group 2 needed an allogenic blood transfusion. INTERPRETATION Total knee arthroplasty can be managed without preoperative AB-donation if it is performed using a tourniquet, if a postoperative collection and direct retransfusion system is used for the wound blood, and if the transfusion algorithm is defined according to compulsory and practical guidelines.

Abstract
For patients undergoing major hepatic resection, acute normovolemic hemodilution is a safe technique that effectively reduces allogeneic red blood cell transfusions. In the recent prospective randomized controlled trial completed at MSKCC, there was no difference in the extent of resection, intraoperative blood loss, operative time, incidence and grade of complications, or length of hospital stay between patients who underwent ANH versus standardintraoperative management. Although ANH does reduce the rate o f allogeneic red blood cell transfusions in patients undergoing major hepatectomy, its benefit is particularly pronounced in patients who have significant operative blood loss (i.e., >800 mL). In these patients, the benefit of ANH extends also to the transfusion of FFP. Thus, ANH should be considered for routine use in patients undergoing major hepatectomy who have an expected considerable blood loss. However, given the relatively low transfusion rate overall, future efforts should be directed at preoperatively identifying patients most likely to benefit from ANH.

Abstract
BACKGROUND Hepatic resection is the most effective treatment for many malignant and benign conditions affecting the liver and biliary tree. Despite improvements, major partial hepatectomy can be associated with considerable blood loss and transfusion requirements. Transfusion of allogeneic blood products, although potentially life-saving, is associated with many potential complications. The primary aim of this study was to determine if acute normovolemic hemodilution (ANH), an established blood conservation technique, reduces the requirement for allogeneic red cell transfusions in patients undergoing major hepatic resection. METHODS One hundred thirty patients undergoing major hepatic resection (> or =3 segments) were prospectively randomized to undergo either ANH or standard anesthetic management (STD). In the ANH group, intraoperative blood collection was performed to a target hemoglobin of 8.0 g/dL. Low central venous pressure anesthetic technique was used intraoperatively for both groups. A standardized transfusion protocol was applied to all patients intraoperatively and throughout the hospital stay. RESULTS From April 2004 to March 2007, 63 patients were randomized to ANH and 67 to STD. Demographics, diagnoses, liver function, extent of resection, intraoperative blood loss, operative time, incidence and grade of complications, and length of hospital stay were similar between the 2 groups. ANH reduced the overall allogeneic red cell transfusion rate by 50% compared with STD [12.7% (n = 8) vs. 25.4% (n = 17), respectively; P = 0.067. ANH patients were less often transfused intraoperatively (n = 1, 1.6%) compared with the STD group (n = 7, 10.4%) (P = 0.036), had higher postoperative hemoglobin levels (P = 0.01), and tended to require fewer red cell units overall (28 vs. 47 units). In patients with intraoperative blood loss > or =800 mL, ANH reduced not only the allogeneic red cell transfusion rate (18.2% vs. 42.4%, P = 0.045) but also the proportion of patients requiring fresh frozen plasma (21.1% vs. 48.3%, P = 0.025). CONCLUSION For patients undergoing major liver resection, ANH is safe, effectively reduces the need for allogeneic transfusions, and should be considered for routine use. Given the modest transfusion rate in the STD arm, future efforts should attempt to target ANH use to patients most likely to benefit.

Abstract
INTRODUCTION This is a prospective study looking at the effectiveness of autologous postoperative drains in primary uncemented total hip replacement (THR) surgery. PATIENTS AND METHODS A total of 86 patients were studied, with 43 using standard suction drains (normal drain group) and 43 using autologous drains (autologous drain group). RESULTS Thirty-seven units of homologous blood were transfused in the normal drain group and 5 units in the autologous drain group. The mean number of units of homologous blood transfused per patient was reduced from 0.86 to 0.12 (P < 0.01) with the use of autologous drains and the transfusion rate was reduced from 23% to 6% (P < 0.02). The mean length of hospital stay was also reduced by two nights (P < 0.05). There were no adverse effects from using the autologous system and it does reduce the need for a homologous blood transfusion. CONCLUSIONS The system is simple and easy to use and we have also found it to be cost effective. Previously, it has not been reported as being effective in hip arthroplasty surgery, unlike knee arthroplasty surgery. We would recommend using autologous postoperative drains in primary THR surgery.

Abstract
BACKGROUND AND PURPOSE Assessment of risk factors associated with the use of perioperative allogeneic blood transfusion and the effect of transfusion on infectious complications after ileal pouch-anal anastomosis (IPAA). METHODS All patients included had IPAA with ileostomy. They were divided into two groups: transfused (TRAN); nontransfused (NON). Data included age, gender, preoperative anemia (Hgb <9 l g/dl), operative blood loss, transfusion volume, incidence of postoperative infectious or anastomotic complications, and length of stay (LOS). RESULTS The 1,202 patients eligible for the study were divided into: TRAN = 240 patients and NON = 962 patients. The patient age, sex, and preoperative steroid use were similar in both groups. Significantly, more patients in the TRAN group were anemic preoperatively (32 vs 11%; p<0.05) and the preoperative Hgb level was significantly lower in the TRAN (12.07; p<0.05 vs 13.34 g/dl). Transfusion was required more frequently in anemic patients (p<0.001). The overall infection rate was significantly higher in the TRAN (48.75 vs 11.22%, p<0.001), Anastomotic separation (10.83 vs 3.32%, TRAN and NON, respectively; p<0.001) and fistula formation percentage (20.8 vs 4.46%, TRAN and NON, respectively; p<0.001) was significantly higher in the TRAN group. Pelvic sepsis also occurred more frequent in TRAN (22.9 vs 4.2%, TRAN and NON, respectively; p<0.001). The incidence of any infectious complication at any site was higher in anemic patients irrespective of transfusion status (18.2 vs 2.8%, p<0.05). Transfusion was the only significant independent risk factor for postoperative infections. LOS was adversely affected by an infectious complication (9 vs 7 days, p<0.001). CONCLUSIONS Preoperative anemia is a significant risk factor for perioperative transfusion with significant increase in postoperative infectious complications and anastomotic complications after IPAA. Strategies to correct preoperative anemia, refine indications for transfusion, and define the use of blood salvage techniques may be helpful in decreasing this risk.

Abstract
BACKGROUND The quality of blood obtained with a device for postoperative blood drainage and autotransfusion (Bellovac-ABT, Astra Tech AB) was investigated in 50 patients who underwent total hip replacement (THR) or total knee replacement (TKR) surgeries. STUDY DESIGN AND METHODS The Bellovac-ABT drainage set was inserted and blood collection began after skin closure (THR) or 15 minutes after tourniquet deflation (TKR). A collecting bag stayed in place for less than 6 hours. The product was then returned after sedimentation and discard of supernatant, without anticoagulants. RESULTS Blood returned with the Bellovac-ABT had optimal hemoglobin levels and red blood cell (RBC) counts; the low platelet count reduced the risk of disseminated intravascular coagulation. Inertia of materials maintained acceptable values of C-reactive protein, whereas cytokines and complement split products rose rapidly. Higher concentrations of adenosine triphosphate and 2,3-diphosphoglycerate than in circulating blood suggested a normal RBC metabolism. No adverse reactions were observed in any participants. CONCLUSION Because of its simplicity and safety, the Bellovac-ABT autologous blood transfusion system is recommended in THR or TKR without joint infection or malignancy.

Abstract
The purpose of this study was to determine the benefits and disadvantages of transfusing autologous blood during abdominal aortic aneurysm (AAA) surgery at a district general hospital with an intraoperative autologous transfusion device (Haemoccel ABT 350). In this retrospective study, 128 patients underwent abdominal aortic aneurysm repair between 1992 and 1999 by a single vascular surgeon. Ninety-three patients (60 autologous and 33 allogeneic) had elective AAA repair (group A) and 25 patients (4 autologous and 21 allogeneic) had emergency AAA repair (group B). Nine group A patients (7.6%) received their own salvaged blood and no other allogeneic blood. Although the mean estimated blood loss was higher in the autologous group of patients (NS), the intraoperative autologous transfusion device did not significantly reduce allogeneic blood usage in patients who had autologous transfusion in both elective and emergency groups. There was no difference in postoperative hemoglobin and hematocrit, ICU stay or hospital stay. In this study, red cell salvage was significantly more expensive than blood bank usage (p < 0.0001), yet it did not significantly reduce the needs of allogeneic blood. We concluded that the intraoperative autologous transfusion device is underused, not cost-effective and requires formulation of local guidelines.

Abstract
Obstetric hemorrhage continues to be a significant cause of maternal mortality and morbidity. Blood transfusion in such circumstances may be life saving but involves exposing the patient to additional risks. Limiting blood transfusion and using autologous blood when possible may reduce some of these risks. This article outlines the techniques that may be used to limit and more effectively treat hemorrhage in the obstetric patient, with particular attention paid to reducing the use of allogeneic blood transfusion.

Abstract
PURPOSE To determine whether salvaged autologous blood collected postoperatively contains complement split products (SC5b-9), and pro-inflammatory cytokines (IL-6 and IL-8) and whether there are any differences between blood collected during hip or knee surgery. METHODS Fifty-eight consecutive patients undergoing hip or knee replacement surgery were studied. Thirty-eight had postoperative bleeding large enough to require infusion of salvaged blood. The salvaged blood was filtered during collection through a 200 microm filter and before infusion a 40 microm filter was used. Samples for complement and cytokine determinations were drawn from the circulation and from the collected blood. RESULTS High concentrations of SC5b-9, IL-6, and IL-8 were found in salvaged blood. The concentrations were higher than in the circulation (P < 0.05). The circulating concentrations of IL-6 and IL-8 were increased 60 min and 12-18 hr after transfusion. There were no differences regarding SC5b-9, IL-6, and IL-8 in the blood collected after hip or knee surgery. CONCLUSION Blood collected from a surgical wound contains large concentrations of inflammatory mediators. There were no differences between blood collected during hip or knee surgery.

Abstract
Elective abdominal aortic aneurysm (AAA) surgery may result in substantial blood loss. Concerns regarding the safety, availability, and acceptability of homologous blood have led to initiatives toward reducing transfusion requirements at the time of aneurysm repair. This study was designed to determine if the routine use of intraoperative red cell salvage and autotransfusion resulted in a reduction in homologous transfusion at our institution. A retrospective review of elective AAA repairs in the years 1987, 1992, and 1997 was carried out. Demographic data, operative details, blood loss, hemoglobin levels, red cell salvage and return volumes, and transfusion requirements were recorded and compared across the study years. From this study we conclude that routine use of red cell salvage and autotransfusion is an effective means for reducing transfusion requirements in elective AAA repair.

Abstract
1. The purpose of this study was to determine whether shed autologous blood collected postoperatively contains complement split products (C3a and SC5b-9) and proinflammatory cytokines (TNF-alpha, IL-1beta, IL-6 and IL-8) and whether transfusion of shed blood increases the concentrations of inflammatory mediators in the circulation. 2. Twenty consecutive patients undergoing total hip replacement surgery under spinal anaesthesia were studied. The patients were transfused with whole blood collected postoperatively. 3. The median volume shed blood returned to the patients was 350 ml (25-75% range = 300-450). Before transfusion of shed blood was filtered using a 40 microm filter (Solcotrans). Samples for complement and cytokine determinations were drawn from the collected blood. 4. Venous blood samples were drawn 1 min before transfusion, 1 and 60 min after completed transfusion. High concentrations of C3a, SC5b-9, TNF-alpha, IL-1beta, IL-6 and IL-8 were found in shed blood. The concentrations were higher than the circulating levels (P < 0.05). The filtration procedure did not significantly reduce the concentrations. 5. Transfusion of the shed blood did not significantly alter the circulating concentrations of C3a, SC5b-9, TNF-alpha, IL-1beta, and IL-8. The plasma concentrations of IL-6 were increased both 1 and 60 min after completed transfusion compared to before (P < 0.05). 6. This study shows that whole blood collected from a surgical wound contains large concentrations of complement split products and proinflammatory cytokines. Transfusion of shed blood leads to elevated plasma levels of IL-6.

Abstract
BACKGROUND The efficacy of intraoperative salvage and washing of wound blood and the predictors of allogeneic red cell transfusions in prosthetic hip surgery are insufficiently known. METHODS In 96 patients, undergoing primary or revision surgery, salvaged and washed red cells and, if necessary, allogeneic blood were used to keep haematocrit not lower than 33%. The bleeding of red cells during hospital stay was calculated from the red cell balance. The preoperative red cell reserve (mililitres of red cells in excess of a haematocrit of 33%) was estimated and the difference between this volume and the total bleeding of red cells was retrospectively used to classify patients with regard to the need for red cells. Stepwise regression analysis was used to define patient-related variables associated with allogeneic blood transfusion. RESULTS Preoperative knowledge of the type of operation (primary, revision), the preoperative red cell reserve, and the body mass could predict roughly half of the need for banked blood (r2 = 0.45). Only one-third of the total bleeding of red cells was retransfused. For complete avoidance of allogeneic blood, autotransfusion was most effective in patients with a moderate need (0-4 u). However, 32% of such patients required allogeneic blood. CONCLUSIONS Autotransfusion has a limited efficacy to decrease the need for allogeneic blood, and other blood-saving methods should be added for this purpose. It is difficult to predict the need for allogeneic blood preoperatively.
