Abstract
- BACKGROUND
Preoperative autologous blood donation (PABD) is a conservation strategy for reducing allogenic blood transfusion (ABT) during minimally invasive cardiac surgery (MICS). We aimed to evaluate the effects of PABD on the frequency of ABT and clinical outcomes in patients undergoing MICS.
METHODS
We enrolled 113 patients (47.8±13.1 years, 50 men) undergoing MICS without preoperative anemia (hemoglobin >11 g/dL) between 2014 and 2017. Of these patients, 69 (the PABD group) donated autologous blood preoperatively and were compared to the non-PABD group (n=44). We analyzed the frequency of perioperative ABT and clinical outcomes.
RESULTS
Baseline characteristics did not significantly differ between groups, although preoperative hemoglobin levels were lower in the PABD group. All operations were performed using a minimally invasive approach. Patients' surgical profiles were similar. There were no cases of mortality or significant differences in early postoperative outcomes. During the early postoperative period, hemoglobin levels were higher in the PABD group. No significant difference was found in the frequency of ABT.
CONCLUSION
Although the PABD group had higher postoperative hemoglobin levels, there was no clear clinical benefit in the early postoperative period, despite a great deal of effort and additional cost. Additional PABD in the setting of strict policies for blood conservation was ineffective in reducing ABT for young and relatively healthy patients who underwent MICS.
