Presentation recorded at the 6th International NPWT Expert Meeting, Berlin 20-21 March 2015.
Cardiothoracic workstream

Onnen Grauhan presented his clinical experience of using NPWT prophylactically in high risk (obese) patients undergoing a sternotomy procedure; he concluded that NPWT over clean, closed incisions, for 6-7 postoperative days significantly reduces the wound infection incidence after median sternotomy1. His ‘all comers’ study observed 237 patients treated with prophylactic NPWT (192 ‘standard’; 45 ‘high risk’ – all treated with KCI Prevena™)2 with a total of 3 wound infections (one in the standard group, two in the high-risk one), which compared very favorably with their historical control group of 3508 patients, showing an incidence of 1.3% vs. an historical value of 3.4% (p<0.05). Professor Grauhan concluded that NPWT provides a “sterile” wound environment, supports improved wound healing through improved microcirculation, drainage, and stabilisation of the wound edges.
