Brief Summary

Only a limited number of studies have been published that monitored the penetration of antibiotics from blood into exudate in patients treated with negative pressure wound therapy (NPWT), and that evaluated the adequacy of current dosage regimens according to antibiotic tissue concentrations. A higher migration rate of several antibiotics (including vancomycin) to exudate has been reported in patients with skin ulcers, skin defects, burns, and traumatic wounds treated with NPWT compared to patients without NPWT. In the present study, the investigators will evaluate the pharmacokinetic profile and wound penetration of vancomycin in open-heart surgery patients with post-sternotomy deep sternal wound infection receiving NPWT.

Outcome Measures

Primary Outcomes (1)

  • Vancomycin penetration into exudate

    To determine the vancomycin penetration into the wound during NPWT, the investigators compared the vancomycin total (bound + unbound) average exudate concentration to the vancomycin total (bound + unbound) average serum concentration on the first study day. The same calculation was used to determine the penetration ratio for free (unbound) vancomycin concentrations on the first study day. For samples from three consecutive days, the investigators compared the vancomycin total (bound + unbound) through exudate concentrations with the vancomycin total (bound + unbound) through serum concentrations. The same calculation was used to determine the penetration ratio for free (unbound) vancomycin concentrations on three consecutive days.

    repeated measurements for the total of 72 hours

Secondary Outcomes (3)

  • Identification of pre-, intra-, and postoperative risk factors for deep sternal wound infection (DSWI) development

    3 days

  • Recurrence of DSWI

    1- year follow-up

  • Determination of mortality

    1- year follow-up

Study Arms (2)

Other: Standard postoperative therapy

Interventions

Vancomycin was administered to the patients at the discretion of the physician

Patients treated with NPWT with DSWI

The patients received standard postoperative therapy

Patients without DSWI after cardiac surgery
