Surgical site infection (superficial/deep/organ):
- Prevalence 5-10%
- Within 10-14 days post surgery
- Most common: Staphylococcus aureus
- Risk factors: neonate, HLHS, hospitalization prior surgery, TPN, emergency procedures, long CPB
Blood stream infection:
- Prevalence 5-10%
- Within 10-14 days post surgery
- Most common: gram negative organism (Pseudomonas, Enterobacter)
- Risk factors: surgical complexity, open sternum, low body weight, longer duration of central line, prolonged ICU stay
Pulmonary infection:
- Prevalence 10%
- Risk factors: prolonged mechanical ventilation, surgical complexity, low cardiac output syndrome, failed extubation
Current recommendation for antimicrobial prophylaxis in cardiac surgery: cefazolin up to 72 hrs (prolonged use may increase antimicrobial resistance). In the setting of either a presumed or known Staphylococcal colonisation, the hospital presence of a high incidence of MRSA, patients susceptible to colonisation, or an operation for a patient having prosthetic valve or vascular graft insertion, it would be reasonable to combine the beta-lactam with a glycopeptide (vancomycin) for prophylaxis.
Special considerations in immunodeficient syndromes (DiGeorge Syndrome, postoperative – see chylothorax).
