Abstract
BACKGROUND
Around 36,000 cardiac operations are undertaken in the United Kingdom annually, with most procedures undertaken via median sternotomy. Wound complications occur in up to 8% of operations, with an associated mortality rate of around 47% in late or undetected cases.
OBJECTIVE
To undertake a systematised literature review to identify pre-operative, peri-operative and post-operative risk factors associated with sternal wound complications.
METHODS
Healthcare databases were searched for articles written in the English language and published between 2013 and 2021. Inclusion criteria were quantitative studies involving patients undergoing median sternotomy for cardiac surgery; sternal complications and risk factors.
RESULTS
1360 papers were identified, with 25 included in this review. Patient-related factors included: high BMI; diabetes; comorbidities; gender; age; presenting for surgery in a critical state; predictive risk scores; vascular disease; severe anaemia; medication such as steroids or α-blockers; and previous sternotomy. Peri-operative risk increased with specific types and combinations of surgical procedures. Sternal reopening was also associated with increased risk of sternal wound infection. Post-operative risk factors included a complicated recovery; the need for blood transfusions; respiratory complications; renal failure; non-diabetic hyperglycaemia; sternal asymmetry and sepsis.
CONCLUSION
Pre, peri and post-operative risk factors increase the risk of sternal wound complications in cardiac surgery. Generic risk assessment tools are primarily designed to provide mortality risk scores, with their ability to predict risk of wound infection questionable. Tools that incorporate factors throughout the operative journey are required to identify patients at risk of surgical wound infection.
