In a double-blind, placebo-controlled clinical study, researchers explored the potential benefits of administering recombinant human erythropoietin (r-HuEPO) to patients undergoing elective colorectal surgery. The primary objectives were to assess the effect of r-HuEPO on perioperative hemoglobin concentrations and the consequent need for blood transfusions.
Participants in the study were selected based on a preoperative hemoglobin level below a specified threshold, making them more likely to require transfusions during or after surgery. The study design included two groups: one receiving doses of r-HuEPO and the other a placebo. All other perioperative care protocols were standardized to maintain consistency across both cohorts.
The results demonstrated that patients who received r-HuEPO experienced a statistically significant increase in their perioperative hemoglobin concentrations compared to those in the placebo group. Furthermore, the need for allogeneic blood transfusions was reduced in the r-HuEPO group, suggesting that the medication may be a valuable tool in managing anemia in surgical patients.
These findings support the potential clinical utility of r-HuEPO as part of a blood conservation strategy in elective colorectal surgery, particularly for patients with preexisting anemia. However, the researchers recommend further studies to determine optimal dosing, evaluate long-term outcomes, and assess cost-effectiveness before widespread clinical adoption.
