Lower Extremity Regional Anesthesia and Infrainguinal Bypass Grafting

Plain-language summary

In this investigation, the investigators will attempt to demonstrate that patients who have received nerve blocks (regional anesthesia) prior to open surgical vascular bypass of the lower extremities (infrainguinal bypass grafting) will have improved surgical outcomes namely a reduction in the rates of death, wound infection, graft thrombosis, graft revision, and amputation. As well, the investigators anticipate that patients who have undergone regional anesthesia for infrainguinal bypass grafting will have improved secondary outcomes with respect to a decreased length of stay, narcotic consumption, nausea and vomiting, post-operative cognitive dysfunction, major cardiac events, post-operative pain, and hyperglycemic episodes.
