Clinical outcome of pre-operative blood transfusion for sickle cell disease patients in post-operative complications.

BACKGROUND

Preoperative blood transfusion for patients with sickle cell disease is a debatable topic and it can be lifesaving. Sickle cell disease patients are at high risk for vaso-occlusive crisis due to the large concentration of sickle hemoglobin (HgbS) in their blood. Despite the current extensive research into this disease, there is still no consensus over whether blood transfusion is a preferable preoperative modality among patients undergoing elective surgical procedures.

METHOD

A retrospective observational study, which enrolled 204 patients with Sickle cell disease who underwent surgery at King Fahad Hospital of the University (KFHU) over the last five years. The primary objective was to determine whether there is evidence that preoperative blood transfusion for SCD patients undergoing surgical procedures will reduce postoperative complications related to SCD.

RESULTS

A total of 204 patients were included, of which 30% had preoperative blood transfusion. Majority of patient 44% had undergone cholecystectomy. On multivariate logistic regression analysis, patients who did not undergo blood transfusion had significantly higher risk to develop post-operative SCD complications (OR = 3.07, P value = 0.002). In addition, they had significantly prolonged hospitalization (OR = 2.22, P value = 0.08). In contrast, patients who received blood transfusion had lower risk for developing post-operative SCD-related complications (OR = 1.87, P value = 0.29), and decrease in the duration of hospitalization by (OR = 0.49, P value = 0.045).

CONCLUSION

Our study showed that patients who had not undergone preoperative blood transfusion had higher risk to develop postoperative complications and prolonged hospital stay compared to those who underwent blood transfusion.
