Poststernotomy mediastinitis: comparison of two treatment modalities

Area of Science:

• Cardiovascular Surgery
• Infectious Diseases
• Medical Devices

Background:

• Poststernotomy mediastinitis (PM) is a severe complication after median sternotomy, with incidence ranging from 0.4-5%.
• Optimal management strategies for PM remain debated.
• High morbidity and mortality rates are associated with PM.

Purpose of the Study:

• To compare the effectiveness of topical negative pressure (TNP) therapy versus traditional closed drainage techniques (CDT) for treating PM.
• To evaluate outcomes including mortality, infection recurrence, and treatment duration.

Main Methods:

• Retrospective review of 63 patients treated for PM between 1992 and 2003, following median sternotomy.
• Patients were divided into two groups: 29 treated with TNP and 34 with CDT.
• Data collected included treatment modalities, mortality, infection recurrence, therapy duration, and hospital stay.

Main Results:

• The overall incidence of PM in the study cohort was 0.6%.
• The TNP group demonstrated significantly lower rates of recurring infection and therapeutic failure (P<0.05).
• Fewer defects at discharge were observed in the TNP group.

Conclusions:

• PM is a significant contributor to patient morbidity and mortality.
• Topical negative pressure (TNP) therapy is a safe and adequate treatment option for poststernotomy mediastinitis.
• TNP therapy may offer improved outcomes compared to conventional closed drainage techniques.
