Blood transfusion and postoperative wound infection in intracapsular femoral neck fractures

The relationship between blood transfusion and postoperative wound infection was studied in 695 operations for cervical hip fractures. A total of 156 (22%) patients were transfused with a total of 392 units of blood. A total of 31 (4.5%) patients developed a postoperative superficial or deep wound infection. Cultures identified Staphylococcus aureus as the cause in 71% and E. coli in 9.7% of the infections. A total of 11 out of 156 (7.05%) transfused patients developed a wound infection. In contrast only 20 out of 539 (3.71%) non-transfused patients developed a wound infection (p < 0.05).
