Clinical Trials

Have you been diagnosed with orthostatic intolerance? This study aims to find out how the body’s regulation of basic functions, such as heart rate and blood pressure, is altered in people who have orthostatic intolerance. This condition, which has an unknown cause, is characterized by a racing heartbeat, dizziness, lightheadedness, and other symptoms that occur when a person stands up. To participate in this study, you must be between 18 and 80 years old and have orthostatic intolerance. This study is located in Nashville, Tennessee.

Do you have low blood pressure due to primary autonomic failure from a medical condition such as Parkinson disease, multiple system atrophy, or pure autonomic failure? Autonomic failure is caused by problems with a part of the nervous system called the autonomic nervous system. People with this condition can suffer debilitating low blood pressure upon standing. This study is testing the use of compression garments compared with a medicine called midodrine to improve blood pressure. To participate in this study, you must be between 18 and 80 years old and have low blood pressure when standing. This study takes place in Nashville, Tennessee.

Data from a randomized clinical trial are urgently needed to determine the effect of ketamine versus etomidate on cardiovascular complications and clinical outcomes of emergency tracheal intubation.

Do you or a loved one have pneumonia? This study will test whether combining two medicines to reduce inflammation of the airway and to keep it open may help prevent respiratory failure in people who have pneumonia. To participate in this study, you must be at least 18 years old and have severe pneumonia with low blood oxygen levels.

Are you being treated in the ICU for acute respiratory failure? This study is looking at whether treating depression along with physical therapy helps people recover faster from respiratory failure. After leaving the ICU, you will be visited at your home by a physical therapist and occupational therapist who will talk to you about your goals for recovery and what activities you value the most. They will then design a plan for you that includes a type of talk therapy for depression called behavioral activation. To participate in this study, you must be at least 18 years old and undergoing treatment for acute respiratory failure for more than 24 hours in the ICU. This study is located in Baltimore, Maryland.
