Trial design
CTIS Part I — objectives, methods, condition coding
Main objective
Scope: Efficacy
Demonstrate the efficacy of urea therapy in correcting persistent hyponatremia despite adequate management (Appendix 2), during SAH.
Secondary objectives 7
- Compare the sodium intake required to correct natraemia
- Study the mechanism of action of urea
- Assess the impact of treatment on length of stay
- Evaluate the impact of treatment on neurological outcome at 3 months from inclusion
- Assessing adverse effects of treatment
- Persistence of natraemia correction 48H after discontinuation of treatment
- Comparison of speed of correction of natraemia
