Consistent with previous studies, female gender and obesity were identified as independent risk factors for leg harvest site infection, while previous cerebrovascular accident, postoperative transfusion, and older age are newly described risk factors. The Society of Thoracic Surgeons database is a useful tool for identification of predictors of leg harvest site infections.
We identified modifiable risk factors for SSI including antibiotic dosing and body temperature during surgery. Preoperative antibiotic administration is likely to benefit from standard processes. Further studies of risk benefit for prolonged low body temperature during procedures are needed to determine the optimal balance between neuroprotection and potential immunosuppression associated with low body temperature.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
