Abstract
The objective of this study was to assess the clinical and financial outcomes of intraoperative cell salvage (ICS) during abdominal aortic surgery. In this study, 90 patients were operated on with the use of ICS (group 1, prospective) and 90 patients without ICS (group 2, historical control). According to the type of operation, the patients were subdivided into three consecutive 30-patient subgroups (1, aortoiliac occlusive disease [AOD]; 2, elective abdominal aortic aneurysm [AAA]; or 3, ruptured abdominal aortic aneurysm [RAAA]). Transfusion requirements and postoperative complications were recorded. The total amounts of perioperatively transfused allogeneic blood were higher in all patient subgroups that underwent surgery without ICS ( p = .0032). In the ICS group, 50% of AOD patients and 60% of elective AAA patients received no allogeneic transfusions. There were no significant differences in the incidence of postoperative complications in any group examined. ICS significantly reduced the necessity for allogeneic transfusions during abdominal aortic surgery. ICS use was most valuable in urgent situations with high blood losses, such as RAAA, for which only small amounts of allogeneic blood were initially available. In patients with more than 3 units of autologous blood reinfused, this method was cost effective.

Abstract
The use of the Continuous AutoTransfusion System (C.A.T.S; Fresenius Hemotechnology, Bad Homburg v.d.H., Germany), which conserves allogenic blood, is reported in 187 patients having abdominal aortic aneurysm repair during a 9-year period. Patients were allocated to C.A.T.S if a Haemovigilance technician was available. A mean of 685 mL of retrieved blood was reinfused in 101 patients receiving C.A.T.S; 61% required 2 U or less. All control patients required 3 U or more of allogenic blood. Allogenic transfusion in C.A.T.S patients decreased significantly (P < .0001). Mean intensive care unit stay was significantly reduced in C.A.T.S patients (P = .042). Mean postoperative hospital stay was 18 days for C.A.T.S group and 25 days in control patients (P = .014). The respective 30-day mortality was 12% versus 19% (P = .199). The C.A.T.S markedly reduced the amount of blood transfused, was associated with reduced intensive care unit and postoperative hospital stay, and was cost-effective.

Abstract
PURPOSE OF REVIEW Abdominal aortic aneurysms still require open repair despite the advances that endovascular aneurysm repair has made in treating patients with significant operative risk. Older patients with significant comorbidities require open repair of their complex aneurysms when they fail to meet anatomic criteria for endovascular aneurysm repair. This review discusses the physiologic insult of abdominal aortic surgery. It aims to address which patients are the highest risk of postoperative morbidity, and advances in their intensive care unit management to reduce such morbidity. RECENT FINDINGS Advanced age, chronic health dysfunction, emergency surgery, and multiple organ failure are independent predictors of postoperative mortality. Myocardial ischemia is the largest contributor to patient morbidity, with any rise in postoperative cardiac troponin I predicting increased in-hospital myocardial infarction and mortality. Highest-risk patients benefit most from optimizing perioperative cardiac status with beta-blockade. Perioperative treatment with fenoldopam may improve renal outcome. Tracheostomy to aid in weaning is associated with increased mortality but may improve outcome in patients with preoperative chronic obstructive pulmonary disease. SUMMARY Demographic trends indicate that open aortic surgery will continue to be performed on older patients with complex aneurysms. Identifying patients at risk and optimizing their postoperative risk factors will improve outcomes.

Abstract
Repair of thoracoabdominal aortic aneurysms (TAAA) is associated with major blood loss, often exceeding the patient's intravascular volume, and complex intraoperative and postoperative coagulopathies necessitating large-volume transfusion of blood products. Abnormalities sufficient to cause thrombocytopenia or clinically important prolongation of clotting parameters are rarely present before surgery in elective aneurysms but are more common with ruptured aneurysms. The finding of intraoperative and postoperative deficiencies of clotting factors, along with thrombin generation and activation of the thrombolytic system, is reflective of massive blood losses, visceral ischemia, and massive transfusions. An aggressive strategy of transfusion of blood products is critical to the prevention of clinically significant coagulopathy during surgery. Adjuncts to reduce blood losses and blood product use include low-dose aprotinin or epsilon -aminocaproic acid, intraoperative blood salvaging, and acute normovolemic hemodilution. In TAAA repair, an average blood loss of 5000 to 6000 mL and average transfusion of allogeneic blood products of 50 to 60 U are to be anticipated.

Abstract
Almost all patients who undergo major craniosynostosis corrections receive allogenic blood transfusions. This study of intraoperative blood salvage was undertaken in an attempt to further reduce the need for blood transfusions and to enhance the safety of these complex procedures. This prospective nonrandomized series included 60 consecutive children undergoing major cranial vault remodeling, primarily for treatment of craniosynostosis (single-suture and syndromic). A single craniofacial surgeon performed all operations, using a cell-saver equipped with a 55-cc pediatric bowl. The average age of the patients in this series was 4 years (33 of 60 patients were less than 18 months of age), and the average length of the surgical procedure was 196 minutes. Fifty-three percent were primary procedures and 47 percent were secondary. The mean estimated blood loss was 356 cc (19 cc/kg, or 28.5 percent of the estimated total blood volume). An average of 110 cc of cell-saver blood (range, 5 to 900 cc), or 7.8 percent of the patient's estimated total blood volume (approximately 15 percent, accounting for hemoconcentration of the cell-saver blood), was recycled for transfusion. No statistically significant factors (primary versus secondary procedure, diagnosis, age, or weight) were identified as predictive indicators for the use of this technology. Although 59 of 60 patients received transfusions, only 18 (30 percent) received allogenic blood (average, approximately 140 cc). There were no complications associated with the use of the cell-saver device. Use of the cell-saver during major craniosynostosis repair seemed to be safe and was associated with an extremely low allogenic blood transfusion rate.

Abstract
A retrospective analysis of 56 patients undergoing ruptured abdominal aortic aneurysm (AAA) repair was performed to find out if cell saver had any impact on postoperative morbidity and mortality. All patients but one were male. The mean age was 68 +/- 8 years (35-85 years). Cell saver was used in 40 patients (CS group) and was not used in 16 patients (NCS group). We compared the incidences of respiratory, renal, and gastrointestinal complications; reoperation; transfusion requirement; length of hospital stay; and mortality between the groups. This study demonstrated that intraoperative cell saver usage significantly increased the incidence of respiratory complications and the need for blood and fresh frozen plasma transfusion, and prolonged the hospital stay in patients with ruptured AAA, but did not have any impact on mortality. Postoperative complications were more prominent in patients who received >3000 mL cell saver blood.
