Monitoring blood flow and oxygen during long pelvic surgeries to prevent leg injury

This is a research study designed to test whether two FDA-approved monitoring devices can help doctors detect a rare but serious leg injury that can happen during long pelvic surgeries. The devices measure blood flow and oxygen levels in your legs during surgery. Researchers want to learn whether these measurements can catch problems early, before you wake up and experience permanent damage.

When pelvic surgeries last many hours with patients in a certain position, the legs can sometimes become starved of oxygen and blood flow, causing muscle and nerve damage that may not be noticed until after surgery. The researchers hope that continuous monitoring during surgery could catch this problem early enough to prevent lasting harm.
