Participant milestones

Participant milestones
Measure
Cases
The first 15 subjects enrolled will receive the intervention drug daptomycin as surgical antibiotic prophylaxis.
Controls
15 subjects will be enrolled in the standard of care antibiotic group to serve as the controls. Controls will receive no experimental medications or treatments. The purpose of enrolling control patients was to serve as a reference group for intervention patients. Specifically cases and controls will be compared for changes in commonly collected hematologic parameters, creatinine, and CPK. Additionally, parameters collected during anesthesia will be compared. Controls will be matched to the intervention group by age (+/- 10 years), gender, and ethnicity.
