No statistical difference in sternal dehiscence or mediastinitis was found irrespective of whether the bilateral and longitudinal parasternal closure or the conventional peri/trans-sternal wiring technique was used, but there was an obvious, positive influence on sternal dehiscence, deep sternal wound infection, and clinical parameters. However, the study population is relatively small.

As a primary treatment for PM two treatment modalities are currently in use: primary reclosure coupled with a double-tube suction/irrigation system versus V. A. C.(R) therapy. Since prospective randomized studies have not yet been performed, controlled clinical trials comparing both treatment modalities are pivotal to define the evidence for patients presenting with PM.

There are various primary treatment modalities of managing deep sternal wound infection (DSWI) following cardiac surgery, namely surgical debridement with primary reclosure in conjunction with irrigation, Vacuum-assisted closure (V.A.C. therapy, and primary or delayed flap closure. The purpose of this study was to assess whether there is consensus of the primary management of DSWI using one method as a single line therapy or a combination of these procedures. Therefore, a questionnaire with regards to the primary treatment modalities of DSWI was distributed to all 79 German heart surgery centers. All replied to the questionnaire. V.A.C. is used in 28/79 (35%) heart centers as the 'first-line' treatment, 22/79 (28%) perform primary reclosure in conjunction with a double-tube irrigation/suction system, and in 29/79 (37%) clinics both treatment options were used according to intraoperative conditions. Mostly, as a primary management of DSWI two treatment modalities are mainly in use: primary reclosure coupled with a double-tube suction/irrigation system and V.A.C. therapy. The current understanding is based purely on retrospective studies, not evidence-based medicine. Since prospective randomized studies have not yet been performed, controlled clinical trials comparing these treatment modalities are pivotal to define evidence for patients presenting with DSWI.

Although changes in the kidney tissue of newborn piglets are detectable after any cardiac procedure, changes are more profound after cardiopulmonary bypass with mild hypothermia.
