Clinical Trial Summary

This pilot study will compare the two hypertonic solutions currently used for subarachnoid hemorrhage (SAH) - related complications and to determine if the reduction of chloride load is safer, and as efficacious as the classic hypertonic solution.

Description:

This pilot study aimed to collect high-quality randomized and prospective information to help plan a future, larger multicenter trial. The study will compare the two hypertonic solutions currently used for subarachnoid hemorrhage (SAH) - related complications and to determine if the reduction of chloride load by using a sodium acetate and sodium chloride mixture can lead to a relative reduction of serum chloride, reduce kidney injury, and as efficacious as the classic hypertonic solution.

Hyperosmolar therapy is one of the mainstay treatments for SAH-related cerebral edema and vasospasm, in order to reduce delayed cerebral ischemia. Recent evidence from the literature correlates high chloride load when applying IV fluids with worse outcome in a variety of critically-ill patients. Hypertonic saline, with which most hyperosmolar treatment is done, contains a supra-physiologic chloride load. It is possible that by changing the hypertonic solution to a "chloride-lean" one, the study team would be able to reduce the side effects of hypertonic sodium-chloride without losing its efficacy in treating SAH-related complications.

Eligibility

Inclusion Criteria:

• Spontaneous SAH with an identified aneurysmal source as identified on neuroimaging obtained at admission to Emory University Hospital or with imaging at an outside hospital

• Age = 18 years

Exclusion Criteria:

• SAH related to non-aneurysmal vascular anomaly

• Hemorrhage
• Subarachnoid Hemorrhage

Intervention

Drug:
• Sodium chloride /sodium acetate (16.4%)
Sodium Acetate is a sterile, nonpyrogenic solution of Sodium Acetate intended as an alternative to sodium chloride to provide sodium ion in parenteral (IV) fluid therapy. Sodium Chloride is sterile, nonpyrogenic hypertonic saline (concentrated sodium-chloride) solution for parenteral (IV) fluid therapy.
• Sodium chloride (23.4%)
Sodium Chloride is sterile, nonpyrogenic hypertonic saline (concentrated sodium-chloride) solution for parenteral (IV) fluid therapy.
• PlasmaLyte
PlasmaLyte is an isotonic IV solution that mimics human physiological plasma electrolyte concentrations, osmolality and pH.

Outcome

Type	Measure	Description	Time frame	Safety issue
Primary	Difference between serum chloride level on randomization day and the peak afterwards	Serum chloride levels will be measured as part of standard of care. Difference between serum chloride level on randomization day and the peak afterwards will be calculated.	Baseline, up to once daily during a patient's stay in the ICU, and up to 90 days
Secondary	Number of patients with acute kidney injury (AKI)	AKI diagnosis will be done on the basis of clinical parameters (serum creatinine = 1.5 times baseline or =0.3 mg/dl and urine output (<0.5 ml/kg/h for 6 hours) according to Kidney Disease Improving Global Outcomes (KDIGO). Number of patients with acute kidney injury (AKI) will be recorded.	Patients' stay in the ICU, and up to 90 days
Secondary	All causes of in-hospital mortality.	All causes of in-hospital mortality, including withdrawal of treatment or discharge to a hospice facility, will be recorded.	Patients' stay in the ICU, and up to 90 days
Secondary	All causes of 90 day mortality.	All causes of mortality, 90 days post admission day, including withdrawal of treatment or discharge to a hospice facility, will be recorded.	Up to 90 days
Secondary	Change in intracerebral pressure (ICP) measured by ICP monitor following hypertonic treatment.	Change in intracerebral pressure (ICP) following the administration of the hypertonic solution will be recorded.	Continuous measurement as long as the patient has an indication for an ICP monitor, and up to 90 days
Secondary	Change in serum sodium level following the administration of the hypertonic solution.	Serum sodium levels will be measured as part of standard of care. Difference between serum sodium level on randomization day and the peak afterwards will be calculated.	Baseline, and daily during a patient's stay in the ICU, and up to 90 days
