| Abstract: | "BACKGROUND: The normal healing of surgical wounds can be disrupted by infection and/or dehiscence, leading to development of chronic, non-healing wounds (NHW). Diagnosis of NHWs is via clinical acumen and analysis of microbiology wound swabs. Volatile organic compounds (VOCs) are emitted generally by human subjects and specifically as products of bacterial metabolism and are detected in the wound area. This systematic review will assess the potential use of VOCs released by surgical wounds as a non-invasive method for identifying bacterial species and the progression to NHW. METHOD: A systematic search of studies, via PRISMA guidelines, was conducted. Of 220 papers screened, seven studies were included. Outcome data were extracted on methods for VOC analysis and wound/bacterial VOC profiles. RESULTS: The studies have shown that VOC profiles are identified by two methods: gas chromatography-mass spectrometry and electronic nose. There are VOC profiles associated with causative bacterial species, with early indications that they could be anatomically specific or could monitor treatment effects. CONCLUSION: VOC profiling of bacterial species within wounds is possible and could become a point of care test. More research is needed on specific VOC profiles to wound location and whether these profiles may predict progression to NHW" |
