Wound infections after median sternotomy treated by VAC therapy, summary of results, and risk factor analysis
Introduction:
The aim of this study is to summarize results and analyze risk factors for the development of wound infection in heart surgery patients after median sternotomy.
Method:
In this retrospective analysis with assessment of multiple risk factors, we examined 143 patients with infection after median sternotomy treated with VAC therapy from total of 4,650 patients operated in our department from 2012 to 2015.
Results:
Total of 143 patients developed significant SSI treated by VAC therapy following cardiac surgery. Of these, only 14 patients developed DSWI and one patient was diagnosed with suspected osteomyelitis. BMI, female gender, and use of BIMA proved to be statistically significant risk factors in our study (p < 0.001). The acuteness of operations did not have a statistically significant effect. However, it had a significant effect on the severity of infection (p < 0.01). The severity of infection proved to be a significant prognostic factor for patients' outcome (p < 0.01).
Conclusion:
In our study, BMI, female gender, and use of BIMA (bilateral internal mammary artery) in patients with DM were predictors for the development of SWI. The acuteness of operation did not have a statistically significant effect. However, it had a statistically significant effect on the severity of infection (Tab. 3, Ref. 30).
Insights
High BMI, female gender, and bilateral internal mammary artery (BIMA) use are key risk factors for developing surgical site infections (SSI) after heart surgery. These factors predict infection severity and patient outcomes.
Area of Science:
- Cardiovascular Surgery
- Infectious Diseases
- Surgical Site Infections
Background:
- Median sternotomy is a common approach for cardiac surgery.
- Surgical site infections (SSI) are a significant complication following sternotomy.
- Identifying risk factors for SSI is crucial for patient management.
Purpose of the Study:
- To summarize outcomes of patients who developed SSI after median sternotomy.
- To analyze risk factors associated with SSI development in this patient cohort.
- To evaluate the impact of infection severity on patient prognosis.
Main Methods:
- Retrospective analysis of 143 patients with SSI after median sternotomy.
- Data collected from a total of 4,650 cardiac surgery patients (2012-2015).
- VAC therapy was used for treating the identified SSIs.
Main Results:
- Body Mass Index (BMI), female gender, and bilateral internal mammary artery (BIMA) use were significant risk factors for SSI (p < 0.001).
- 14 patients developed deep sternal wound infection (DSWI); one had suspected osteomyelitis.
- Infection severity significantly impacted patient outcomes (p < 0.01).
Conclusions:
- BMI, female gender, and BIMA use predict SSI development in cardiac surgery patients.
- Diabetes Mellitus (DM) was noted as a comorbidity in patients with BIMA use.
- While operation acuteness did not directly predict SSI, it influenced infection severity.
