Objects: Surgical site infection (SSI) remains a major morbidity in patients undergoing cardiovascular surgery. This study evaluated the efficacy of subcutaneous suction drainage in decreasing the risk of SSI of the sternal wound in off-pump coronary artery bypass grafting (OPCAB).
Materials and methods: We invested 106 patients, including 25 women (mean age 70.3 ± 9.6 years old), who underwent OPCAB. Patients were categorized into those with subcutaneous suction drainage of the sternal wound (S group, n = 73) and those without subcutaneous suction drainage (N group, n = 33), and their data were analyzed.
Results: Compared with the N group, the S group had a lower incidence of SSI (N vs. S: 9.1% vs. 0.0%, p = 0.029) and significantly shorter hospitalization duration (N vs. S: 23.2 ± 10.5 vs. 16.6 ± 5.7 days, p < 0.001). No bacteria were isolated from patients with SSI. Patients with SSI were treated and completely cured with continuous negative-pressure wound therapy.
Conclusions: Recent approaches to SSI prevention that include a subcutaneous suction drainage system can result in better outcomes by reducing the risk of SSI after OPCAB.
