Interest of Impedancemetry in Monitoring Hydration and Hyponatremia During Subarachnoid Hemorrhages

What this Trial Is About

Subarachnoid hemorrhage (SAH) is a serious and rare type of stroke caused mainly by the rupture of an intracranial aneurysm, leading to bleeding in the meningeal spaces. One significant late complication is delayed cerebral ischemia (DCI), which causes new neurological problems. To prevent issues related to blood volume changes, especially hyponatremia, it is important to carefully evaluate water and sodium balance, which is challenging using only indirect clinical and biological measures. This study evaluates the use of impedancemetry, a diagnostic test that measures body water volumes and sodium load, to help manage hydration and sodium levels in patients with SAH. Each participant will receive repeated impedancemetry measurements during their hospital stay in addition to standard care. These measurements will be compared to usual hydration and sodium tests, and the agreement with clinical status will be assessed. Participants will be monitored every 48 hours during their average 21-day stay in the neurological intensive care unit. Researchers will measure hydration levels and monitor sodium balance through repeated assessments. The study focuses on how impedancemetry can assist in the ongoing management of hydration and hyponatremia in this patient group, with careful tracking throughout their hospital course.
