Vaidehi Paranjape, Natalia Henao-Guerrero, Giulio Menciotti, All SACS and Siddharth Saksena VT Dept of Civil and Enviro Engineering have published "Evaluation of Four Cardiac Output Measurement Techniques During A Modified Passive Leg Raise Maneuver in Anesthetized Dogs" in Veterinary Anesthesia and Analgesia.

Modified passive leg raise maneuver (PLRM) is a successful volumetric predictor of fluid responsiveness in dogs during experimental induction and correction of hypovolemia using invasive pulmonary artery thermodilution (PACTD) for measuring cardiac output (CO). In this study, other CO methods, minimally-invasive esophageal Doppler (ESD), transesophageal echocardiography (TEE), arterial pressure waveform analysis (APW), noninvasive electrical velocimetry (EV), were investigated during PLRM in anesthetized dogs. During PLRM, the performance of TEE and EV was clinically acceptable in estimating changes in CO, whereas, ESD and APW significantly overestimated CO values.

Paranjape is assistant professor of anesthesiology and pain management, Guerrero is service chief and associate professor of anesthesiology, and Menciotti is assistant professor of cardiology in the college's Department of Small Animal Clinical Sciences, which is led by department head Guerrero.
