Summary

This trial will test whether adding vancomycin to cefazolin can reduce surgical site infections, and whether short-term prophylaxis is as effective as long-term prophylaxis.

Who is the study for?
Adults (18+) needing open-heart surgery can join this trial. It's not for those already on antibiotics, previous participants, known MRSA carriers, people allergic to beta-lactams that prevent cefazolin use, or anyone in another interfering study.
What is being tested?
The trial is testing if adding vancomycin to standard cefazolin before heart surgery prevents infections better and whether short-term antibiotic use is as good as long-term. It's a pilot study to see if a larger trial would work.
What are the potential side effects?
Possible side effects include infections with C. difficile or the emergence of resistant bacteria due to exposure to the antibiotics vancomycin and cefazolin.

Trial Design

4Treatment groups
Experimental Treatment
Group I: Combination therapy, short courseExperimental Treatment2 Interventions
One pre-op dose of cefazolin 30-60 minutes prior to surgery followed by a second dose either four hours after the first dose or upon wound closure (whatever comes first) will be administered. In addition, one dose of vancomycin 60-90min pre-op will be administered.
Group II: Combination therapy, long courseExperimental Treatment2 Interventions
One pre-op dose of cefazolin 30-60 minutes prior to surgery followed by a second dose either four hours after the first dose or upon wound closure (whatever comes first) will be administered followed by additional five doses every eight hours postoperatively (last dose 44 hours after the first dose). In addition, one dose of vancomycin 60-90min pre-op will be administered followed by 3 post-op doses every 12 hours (last dose 36 hours after first dose)
Group III: Cefazolin monotherapy, short courseExperimental Treatment1 Intervention
One pre-op dose of cefazolin 30-60 minutes prior to surgery followed by a second dose either four hours after the first dose or upon wound closure (whatever comes first) will be administered
Group IV: Cefazolin monotherapy, long courseExperimental Treatment1 Intervention
One pre-op dose of cefazolin 30-60 minutes prior to surgery followed by a second dose either four hours after the first dose or upon wound closure (whatever comes first) will be administered followed by additional five doses every eight hours postoperatively (last dose 44 hours after the first dose).
