Summary
Extracorporeal circulation surgery can lead to anemia in 10-11% of patients due to erythrocyte damage and altered osmotic balance. Postoperative anemia presents with various abnormal red blood cell morphologies.
Area of Science:
- Hematology
- Cardiovascular Surgery
- Medical Ultrastructure
Background:
- Extracorporeal circulation (ECC) is a vital procedure in cardiac surgery.
- Understanding the impact of ECC on erythrocyte integrity is crucial for patient outcomes.
- Anemia is a potential complication following major surgical interventions.
Purpose of the Study:
- To investigate the erythrocyte stereo-ultrastructure in patients undergoing ECC.
- To determine the incidence and causes of anemia in the early and late postoperative periods.
- To characterize the morphological changes in erythrocytes associated with ECC-induced anemia.
Main Methods:
- Scanning electron microscopy (SEM) was employed to examine erythrocyte morphology.
- Analysis of 58 patients who underwent surgery with ECC.
- Correlation of erythrocyte changes with hemoglobin levels and clinical outcomes.
Main Results:
- A consistent decrease in hemoglobin levels was observed post-ECC, averaging 3 mg%.
- Anemia (hemoglobin ≤10 mg%) occurred in approximately 10-11% of patients.
- Early postoperative anemia causes include mechanical trauma, osmotic imbalance, and altered membrane plasticity; late anemia is linked to inflammatory processes.
Conclusions:
- ECC significantly impacts erythrocyte structure and function, contributing to postoperative anemia.
- Distinct morphological alterations of erythrocytes are indicative of ECC-related anemia.
- Further research into mitigating ECC-induced erythrocyte damage is warranted.
