  • Impact of infusion of red blood cell suspension at different perioperative periods in patients with valvular heart disease

    Objective To investigate the impact of red blood cell suspension infusion across various perioperative periods on patients with valvular heart disease. Methods The patients with valvular heart disease admitted to Tianjin Chest Hospital from 2018 to 2020 were selected. Based on the timing of perioperative red cell suspension infusion, patients were categorized into three groups: a group 1 receiving intraoperative red cell suspension infusion, a group 2 receiving red cell suspension infusion within 24 hours after entering the ICU, and a group 3 receiving red cell suspension infusion at both time points. Clinical data, laboratory results, perioperative blood component infusion volume, and other relevant parameters were systematically recorded. After propensity score matching, the differences in different variables among the three groups were compared. Results After propensity score matching, 102 patients were enrolled, including 5 males and 50 females, with an average age of 61.74±10.58 years. There were 34 patients in each group. The preoperative hemoglobin (Hb) value of the group 2 was significantly higher than that of the group 1 and the group 3, and the amount of red cell suspension and autoblood transfusion was the lowest (P<0.05). In the group 1, Hb was the highest after surgery, Hb was the highest within 24 hours after surgery, HCT was the highest within 24 hours after surgery (P<0.05). The group 1 had the lowest plasma, platelet and cryoprecipitate infusion volumes, and the shortest cardiopulmonary bypass time, aortic occlusion time, postoperative ICU stay and hospital stay, and the least blood loss, total drainage volume (P<0.05). The difference between postoperative Hb and preoperative △Hb1 was significantly increased in the group 1 (P<0.05). Conclusion The intraoperative infusion of suspended red blood cells in patients with heart valves can be used to indicate to clinicians that patients have a better prognosis at discharge, review and follow-up.
