Abstract:
To determine the impact of intraoperative autotransfusion on vascular surgical care, data related to 304 major vascular surgical operations performed over a 42-month period were retrospectively analyzed. Procedures included abdominal aortic aneurysmectomy (N = 152), aortobilateral femoral bypass (N = 60), thoracoabdominal aortic aneurysmectomy (N = 20), and other vascular procedures (N = 68). Fifty percent of the transfusion requirement was met by autotransfusion for the average patient. The per patient average volumes (liters) autotransfused were as follows: elective abdominal aortic aneurysmectomy, 0.87 L and nonelective, 1.45 L; elective aortobilateral femoral bypass, 0.63 L; elective thoracoabdominal aortic aneurysmectomy, 2.47 L, and nonelective, 2.15 L; and elective other, 0.53 L and nonelective, 1.30 L. Results of immediate postoperative and hospital discharge hemoglobin, hematocrit, and coagulation studies (prothrombin time, partial thromboplastin time, and platelets) did not differ from results of preoperative studies in any group. Neither mortality nor morbidity was related to intraoperative autotransfusion. These data suggest that intraoperative autotransfusion is a safe blood replacement method during major vascular surgical operations.
Insights
Intraoperative autotransfusion safely meets half of blood needs in major vascular surgery. Postoperative outcomes, including hemoglobin and coagulation, showed no difference compared to preoperative levels, indicating safety.
Area of Science:
- Vascular Surgery
- Transfusion Medicine
- Anesthesiology
Background:
- Intraoperative autotransfusion (IAT) is a method for blood replacement during surgery.
- Its impact on major vascular surgical care requires evaluation.
Purpose of the Study:
- To assess the safety and efficacy of intraoperative autotransfusion in major vascular operations.
- To determine if IAT affects postoperative outcomes and patient safety.
Main Methods:
- Retrospective analysis of 304 major vascular surgical operations over 42 months.
- Procedures included abdominal aortic aneurysmectomy, aortobilateral femoral bypass, and thoracoabdominal aortic aneurysmectomy.
- Data on autotransfused volumes, preoperative and postoperative laboratory values, mortality, and morbidity were collected.
Main Results:
- Autotransfusion met 50% of the average patient's transfusion requirement.
- Significant volumes were autotransfused across various procedures, with higher amounts in nonelective cases.
- No significant differences were observed in postoperative hemoglobin, hematocrit, or coagulation parameters compared to preoperative values.
Conclusions:
- Intraoperative autotransfusion is a safe blood replacement strategy for major vascular surgery.
- IAT does not negatively impact postoperative laboratory results, mortality, or morbidity.
- Autotransfusion effectively contributes to blood management in complex vascular procedures.
