Prognostic analysis of perioperative zero red blood cell transfusion in patients with acute Stanford type A

Abstract

Objective To investigate the correlation between perioperative zero red blood cell(RBC) transfusion and the prognosis of patients with acute Stanford type A aortic dissection. Methods A retrospective analysis was made on 96 patients who underwent one-stop Hybrid surgery for acute Stanford type A aortic dissection in our hospital from May 2021 to May 2022. The patients were divided into two groups according to whether they received perioperative RBC transfusion: zero RBC transfusion group (group A, n=26) and RBC transfusion group (group B, n=70). The preoperative general data and laboratory indexes were recorded and the propensity score matching method was used to screen the patients with the same preoperative baseline data, with comparison of operation-related indicators, intraoperative and postoperative blood component dosage and prognostic indicators. Results With BMI index, hemoglobin, platelet count, and troponin T as co variables, 48 patients were included in the study after matching according to 1∶1 propensity score: Group A (n=24) and Group B (n=24). Compared with group A, hemoglobin and hematocrit in group B decreased significantly at the end of operation and 24 h after operation, with a statistically significant difference (P0.05). Conclusion The perioperative hemoglobin of patients with acute Stanford type A aortic dissection with zero RBC transfusion did not significantly decrease, and the postoperative complications and mortality did not increase.
