ClinConnect Summary

This clinical trial is studying the use of a medication called DDAVP to help prevent a dangerous condition called serum sodium overcorrection in patients with severe hyponatremia. Hyponatremia is when the sodium level in the blood is too low, which can lead to serious health issues, especially in patients who are critically ill in the Intensive Care Unit (ICU). The trial is looking for adults aged 18 and older who are currently in the ICU, have severe hyponatremia (with sodium levels below 120 mmol/L) along with neurological symptoms, and have normal or reduced fluid levels in their body.

If someone qualifies for this trial, they will be treated with DDAVP to see if it helps safely manage their sodium levels without causing rapid changes that could be harmful. However, there are specific criteria that could prevent a patient from participating, such as having certain medical conditions like severe kidney disease or heart issues, or if they have had recent surgeries. It's important for potential participants to discuss with their healthcare team whether this trial is a good option for them.
