Aim: Vacuum-assisted closure (VAC) was primarily designed for the treatment of pressure ulcers or chronic, debilitating wounds. Recently, VAC has become an encouraging treatment modality for sternal wound infection after cardiac surgery, providing superior results to conventional treatment strategies.Methods: From November 2004 to September 2006, 34 patients, undergoing VAC therapy for sternal wound infection following cardiac surgery, were prospectively evaluated. Ten patients (29 %) were treated for superfi cial sternal wound infection and 24 (71 %) for deep sternal wound infection. The median age was 69.9 years (range 48 to 82) and the median BMI was 33.4 kg/m 2 (range 28 to 41). Twenty patients (59 %) were women and 19 patients (59 %) were diabetics. Owing to sternal wound infection complications, 16 patients (47 %) were readmitted to the department. VAC was used following the previous failure of the conventional treatment strategy in 7 patients (21 %).Results: Thirty-three patients (97 %) were treated successfully. One patient (3 %) died of multiple organ failure. The overall length of hospitalization was 34.6 days (range 9 to 62). The median number of dressing changes was 4.6 (range 3 to 10). The median VAC treatment time until surgical closure was 9.2 days (range 6 to 21 days). VAC therapy was solely used as a bridge to defi nite wound closure. Three patients (9 %) with chronic fi stula were re-admitted 1 to 6 months after VAC therapy.Conclusions: VAC therapy is a safe and reliable option in the treatment of sternal wound infection in cardiac surgery. VAC therapy should be considered an eff ective adjunct to conventional treatment modalities for the treatment of extensive and life-threatening wound infections following cardiac surgery, particularly in the presence of risk factors.

Aim.To compare assessment of fibrinogen by thromboelastography with the standard von Clauss method. Methods. Observational prospective study. Results. Thromboelastography provides direct and complex evaluation of the entire coagulation cascade based upon changes in blood viscosity. It affects both platelets and plasma components. New application of this method measures fibrinogen contribution to coagulation as opposed to fibrinogen antigen levels measured by immunoassay. Paired samples from 117 patients before cardiopulmonary bypass were compared. A moderate correlation was found between fibrinogen and functional fibrinogen with a Spearman correlation coefficient of 0.476. Conclusion. The functional fibrinogen test is a valid point-of-care method for fibrinogen assay with a moderate correlation to the standard method.
