ABSTRACT
The Bombay Rh D negative is the rarest of the rare in blood groups. A 65-year-old male patient with coronary artery disease was admitted for CABG. During grouping, forward showed no agglutination in A, B, D, and H, and reverse showed agglutination in A, B, and O cell. The blood group was confirmed as Bombay Rh D negative. Four units of PRBC was requested for the surgery as it was cardiothoracic surgery. We checked our inventory and rare donor list for Bombay-negative blood. Acute normovolemic hemodilution was done for 2 units preoperatively with saline replacement. Autologous platelet apheresis was done for this patient. During routine cross-match, one unit was incompatible. The patient had naturally occurring anti-S, which was reactive at 37°C and clinically significant. A total of 4 PRBC (Packed Red Blood Cell), 1 Single Donor Platelet (SDP), 12 Fresh Frozen Plasma (FFP), and 9 cryoprecipitate were transfused throughout the hospital stay. The patient was Bombay Rh negative with anti-S with major surgery, which was re-explored twice; the patient was managed successfully in spite of all these difficulties with cooperation from different blood banks from all over India.
ABSTRACT
OBJECTIVE: This study aimed to retrospectively analyze the blood protective effect of autologous platelet separation in operations for acute aortic dissection. METHODS: A total of 130 patients with acute aortic dissection were enrolled into the present study. The average age of these patients was 52.962±10.5061 years old. These patients underwent the modified aortic arch replacement with the elephant trunk technique or endovascular aortic exclusion with covered stent. Among these patients, 68 patients who underwent autologous platelet separation were assigned to the platelet separation group, while the remaining patients were assigned to the control group. All operations were performed under deep hypothermic circulatory arrest. After anesthesia, 1-2 therapeutic doses of autologous platelets were isolated from patients in the platelet separation group, and these platelets were quickly infused back to these patients after heparin was neutralized by protamine at the end of the cardiopulmonary bypass. The preoperative and postoperative indexes in these two groups were compared. RESULTS: There were no statistically significant differences in age, gender, smoking history, drinking history and hypertension history between these two groups. Compared with controls, the transfusion volume of allogeneic platelets in the perioperative period significantly decreased in the platelet separation group (1.919±1.6226 vs. 0.794±1.1789, Pâ<â#x003C;<â#x200A;0.05), and the use rate of allogeneic platelets also significantly decreased (74.19% vs. 45.59%, Pâ<â#x003C;<â#x200A;0.05). CONCLUSION: The intraoperative auto transfusion of platelets significantly reduced the volume of allogeneic platelet transfusion after the operation for aortic dissection, which has a significant blood protective effect.

@#The incidence of cardiovascular disease remains high, and surgery is an important measure for the treatment of cardiovascular disease. However, cardiovascular surgery is complicated and difficult, and it is one of the departments with the highest rate of allogeneic blood transfusion. Allogeneic blood transfusion significantly increases the complications and mortality of patients, while autologous blood transfusion can effectively reduce allogeneic blood transfusion and adverse reactions. Autologous plateletpheresis technology is a popular autotransfusion method in recent years. This article reviews the autologous plateletpheresis technology and its clinical application in cardiovascular surgery.
