BACKGROUND:Wound healing in cardiac surgery has become a major problem due to the impaired risk profile of many patients. The aim of this study was to prove the influence of autologous platelet gel (APG) on wound healing in a special group of high-risk patients undergoing coronary surgery. PATIENTS AND METHODS: We performed a prospective, double-blind study in 44 patients with a special risk constellation relating to wound complications (obesity, diabetes, smoker, New York Heart Association (NYHA) III-IV and peripheral vascular disease). The study group was treated with APG, prepared using the Magellan platelet separator, the control group underwent conventional wound treatment. RESULTS: The incidence of major and minor wound complications at the thoracotomy, as well as in the area of saphenous vein harvesting, was not pronounced in either of the groups. Blood loss and pain sensations did not differ significantly either. Stay in the intensive care unit (ICU) and the in-hospital mortality were also comparable. The duration of the entire operation and the time until removing the chest-tubes were prolonged in the study group. CONCLUSION: Despite promising results in other fields of surgery, APG shows no beneficial effect in high-risk patients undergoing cardiac surgery. Probably, it depends on different types of microcirculation in atherosclerotic patients, which are quite different from those of other surgical areas. This factor may offset the existing beneficial platelet effects which could be observed, for example, in maxillo-facial surgery.
