Pediatric clinical trials

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.

NCT ID: NCT00208728 Completed - Cardiac Surgery Clinical Trials

Cardiopulmonary Circuits in the Pediatric Population

Start date: May 2003
Phase: N/A
Study type: Interventional

During open-heart surgery, blood flow is supported by a heart-lung machine that both pumps the blood and gives it oxygen. A problem associated with a heart-lung machine is the damage to some of the blood caused by protein in the blood cell sticking to the sides of the heart-lung machine tubing. This breakdown of the blood cell affects the platelets, which help the blood to clot. Use of the un-treated circuit will be phased out within the next few years, as newer technology is available. The use of coated tubing has been shown to decrease problems with post-operative bleeding in the adult population. No studies have been done on the pediatric population. We plan to perform a prospective, randomized study using the un-treated circuits used now, the " Smart" circuit tubing manufactured by Cobe Cardiovascular Inc., Arvada, CO and the PMEA circuit manufactured by Terumo Corporation, Tokyo, Japan. Randomization will be performed by the perfusionist (the person that runs the heart-lung machine) in charge of the case. No one else will be aware of which circuit is being used. There will be no changes in the operation of the heart-lung machine, anesthesia or the surgery because of this study. Blood testing that is standard of care and some additional tests will be performed on a small amount of blood drawn from. the patient via arterial lines. Additional blood sticks will not be required to obtain this sample.
