Low-GI Diet vs High-GI Diet in Individuals With SCI

Spinal Cord InjuriesPostprandial Hypotension1 more

The purpose of this pilot research project is to examine the impact of a low-glycemic index (GI) diet on postprandial hypotension and glucose control in individuals with chronic spinal cord injury. The objectives are: 1) To evaluate the effect of the low-GI diet on the magnitude of postprandial systolic blood pressure drop compared to a high-GI control diet. 2)To evaluate the effect of a low-GI diet on postprandial glucose and insulin responses compared to a high-GI control diet.

Determinants of Changes in Arterial Load Following Exercise

Post-Exercise Hypotension

The goal of this study is to learn about how blood vessel dilation after exercise effects pulse wave reflection and influences the function of the heart in healthy young adults. The main question it aims to answer is: Are post-exercise decreases in reflected pulse waves due to a decrease in the stiffness of large arteries in the leg or an increase in leg blood flow? Participants will exercise on a stationary bicycle at a moderate intensity for 1 hour during two laboratory visits. Participants will take oral antihistamines to block post-exercise dilation at one visit, and they will take placebo pills at the other visit. At both visits, leg blood flow, pulse wave velocity, and heart function will be measured before exercise and for 120-minutes after exercise.

Non-Invasive Cardiac Output Monitor (NICOM) for Goal-directed Fluid Resuscitation for Inpatients...

SepsisHypotension1 more

The Non-Invasive Cardiac Output Monitor (NICOM) is a non-invasive monitor capable of measuring cardiac output (CO) and cardiac index (CI), and stroke volume (SV) and stroke volume index (SVI) based on heart rate. Conceptually NICOM is a technology that utilizes a dynamic response characteristic in assessing the need for fluid administration, whereby SVI is measured before and after a fluid challenge with more fluid given only if SVI increases significantly with administered fluid. Dynamic response technologies are intended to replace older, "static" measures such as central venous pressure (CVP) and pulmonary capillary wedge pressures (PCWP) which are single point measurements utilized to assess the need to administer fluid. The aim is to pilot and evaluate the effectiveness of using The Non-Invasive Cardiac Output Monitor (NICOM) technology for goal-directed fluid resuscitation in adult inpatients with sepsis associated acute hypotension and/or evidence of septic shock (Lactate >= 4.0).

Effect of Midodrine vs Abdominal Compression on Cardiovascular Risk Markers in Autonomic Failure...

Neurogenic Orthostatic HypotensionAutonomic Failure3 more

The purpose of this study is to learn more about the effects of abdominal compression and the medication midodrine, two interventions used for the treatment of orthostatic hypotension (low blood pressure on standing), on hemodynamic markers of cardiovascular risk. The study will be conducted at the Vanderbilt University Medical Center and consists of a screening and 2 testing days, one with abdominal compression and one with midodrine. The total length of the study will be about 5 days.

Phenylephrine and Pulse Pressure Variability

Intraoperative Hypotension

The purpose of this research study is to determine how vasopressors affect a measure of how intravenous fluid is administered in people undergoing surgery who have low blood pressure called Pulse Pressure Variability (PPV). This study will recruit human subjects to undergo simulated hypovolemia called Lower Body Negative Pressure (LBNP) and will receive phenylephrine and placebo, while PPV will be measured in both conditions. This research will help anesthesiologists learn more about how to use PPV in patients undergoing surgery and who need vasopressors.
