[Traction-assisted Negative Pressure Wound Therapy for Pediatric Poststernotomy Mediastinitis:Report of Two Cases]

We herein report two cases of pediatric poststernotomy mediastinitis treated by traction-assisted negative pressure wound therapy (NPWT) with Zip Surgical Skin Closure (Zip), which is a non-invasive skin closure device. We used this device with NPWT in cases of pediatric poststernotomy mediastinitis to stabilize the sternum and reduce the natural retractive forces of the skin. The patients were two boys (two and three months old), with an onset of infection at 13 and eight postoperative days, respectively. The culture examination detected methicillin-susceptible Staphylococcus aureus in both cases. Traction-assisted NPWT with Zip was performed at-75 mmHg for 16 and 33 days, and the wounds healed completely. In conclusion, this modification was successfully applied to treat pediatric poststernotomy mediastinitis and may help reduce the duration of treatment.
