Intensive Management of Pressure and Volume Expansion in Patients With Subarachnoid Hemorrhage (IMPROVES)
June 18, 2013 updated by: Miriam Treggiari, University of Washington
The purpose of our study is to determine how well Triple-H works and how safe it is.
The investigators are hoping to determine the effects of starting the therapy early and to explore if hypervolemia and/or hypertension are beneficial, and what the optimal target ranges are.

Genders Eligible for Study
All
Description
Inclusion Criteria:
- Age more than or equal to 18 years
- Aneurysmal SAH of any clinical grade
- Head computed tomography demonstrating SAH
- Cerebral angiography revealing the presence of cerebral aneurysm(s) in a location that explains the SAH
- Treatment of aneurysm with clipping or coiling must be carried out prior to randomization and within 72 hours of bleeding
- Signed consent by study participant or applicable legal representative within 72 hours after SAH
Exclusion Criteria:
- History of traumatic SAH
- Non-aneurysmal SAH as indicated by no demonstrable aneurysm by cerebral angiography
- Presence of an unsecured intracranial aneurysm(s) at risk of rupture that in the opinion of the Investigator would compromise the safety of the patient or the quality of the data
- Delayed referral with clipping/coiling greater than 72 hours after the initial bleeding
- Time of symptom onset cannot be reliably determined
- Intracranial hypertension (ICP >25 mm Hg) at the time of screening
- History within the past six months and/or physical findings on admission of decompensated congestive heart failure (NYHA functional class III or IV, or objective class C or D)
- Acute, evolving or recent myocardial infarction
- Cardiac arrhythmia or second and third degree atrio-ventricular block causing hemodynamic instability
- Chronic renal failure requiring dialysis
- Suspected or confirmed pregnancy
- Non English speaking
- A condition that would preclude the performance of the neurobehavioral test battery due to a prior diagnosis of Alzheimer's disease, stroke, degenerative condition, cerebral tumor, or mental retardation
- Severe terminal disease with life expectancy less than 6 months
- Refusal of consent

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Normal Fluids & Normal Blood Pressure
Patients are treated with conventional fluid replacement (Normovolemia) and maintenance of blood pressure in a normal range (Conventional Blood Pressure).
|
Patients are treated with conventional fluid replacement (Normovolemia) or increased the fluid replacement (Hypervolemia) for 10 days.
Other Names:
Patients are treated with maintenance of blood pressure in a normal range (Conventional Blood Pressure) or increased the blood pressure (Augmented Blood Pressure) for 10 days.
Other Names:
|
Active Comparator: Increased Fluids & Normal Blood Pressure
Patients are treated with fluids to achieve higher volume expansion (Hypervolemia) and maintenance of blood pressure in a normal range (Conventional Blood Pressure)
|
Patients are treated with conventional fluid replacement (Normovolemia) or increased the fluid replacement (Hypervolemia) for 10 days.
Other Names:
Patients are treated with maintenance of blood pressure in a normal range (Conventional Blood Pressure) or increased the blood pressure (Augmented Blood Pressure) for 10 days.

Time Frame |
---|---|---|
Our primary endpoint is to determine the feasibility of the pilot study within the ICU setting and collect preliminary estimates for sample size calculations.
Time Frame: 6 months
|
1. Estimation of the eligible population once specific study inclusion & exclusion criteria are applied 2. Estimation of enrollment projections, retention, attrition & losses to follow up; 3. Assessment of compliance with protocol instructions; 4. Evaluation of protocol violations; 5. Achievement of pre-determined hemodynamic goals in each study group.
