What this Trial Is About

Oral and gastrointestinal microbiome dysfunction has been demonstrated to be a culprit of various systemic dysfunctions in peripheries such as cardiovascular, nervous, endocrine and musculoskeletal systems. The topic of microbiome dysfunction after surgical intensive care admission is understudied but may be responsible for persistent systemic inflammation clinically observed in surgical intensive care patients. Therefore, the objective of this project is to investigate the oral and gut microbiome after the acute phase of sepsis, severe trauma injury, cardiopulmonary bypass, and major vascular surgery to compare with 108 age-matched healthy population controls
