Other Diagnoses and Conditions 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.

Evaluation of Plasma Volume Using Ultrasound in Disorders of Fluid With Sodium

Start date: February 2012
Phase: N/A
Study type: Observational

Rossi NF & Schrier RW reported that for having differential diagnosis in hyponatremic state, it is important to have a grasp of extra cellular fluid (ECF) volume. However, recent works showed that it is not easy to estimate the ECF state using by physical findings and by usual laboratory methods. Damaraju SC et al. first demonstrated that measuring central venous pressure (CVP) is significant to evaluate the ECF state in hyponatremic patients with intracranial diseases. Accordingly, it may be useful to measure the CVP in the hyponatremic patients. However, usually it is difficult to measure the CVP in all patients with hyponatremia because that the method is due to invasive procedure. With recently development, it is possible to estimate the CVP calculation using cardiac echogram without invasion. However, it is not clear that an evaluation by using such echogram estimates the state of ECF volume in hyponatremic patients. Therefore, the investigators examine whether the CVP calculation by using cardiac echogram by Marcelino P et al. method without invasion is estimated such condition in hyponatremic patients before and after treatments. As the primary endpoint, the VCI index values is investigated and compared with each group before and after correction of disorders of fluid with sodium. Furthermore, some variables including sodium, potassium, chloride, creatinine, BUN, uric acid, osmolality in blood and urine and plasma vasopressin are investigated and compared with each group before and after correction of disorders of fluid with sodium.
