Feasibility and Clinical Utility of Paired Non-Invasive Hemodynamic and Tissue Oximetry Monitoring to Detect Limb Ischemia in Lithotomy-Positioned Surgeries (NCT07387653)

๐ŸŸข Recruiting Interventional Protocol ๐Ÿ“Š Observational Clinical Research Sponsor: The University of Texas Health Science Center, Houston

๐Ÿฉบ Plain-English Summary (8th-Grade Level)

The LIMB Study is a prospective, observational pilot study evaluating the feasibility of combined non-invasive hemodynamic and lower-limb tissue oximetry monitoring during prolonged minimally invasive pelvic surgeries performed in lithotomy position. Thirty patients will undergo continuous intraoperative monitoring, with the primary outcome being the frequency and duration of tissue oxygen desaturation events and secondary outcomes examining correlations with postoperative limb pain, sensation, and motor function. The study is non-interventional, poses minimal risk, and aims to generate preliminary data to inform future strategies for early detection and prevention of limb ischemia and well-leg compartment syndrome
