Study Arms (2)

Intrathecal Treatment Group

EXPERIMENTAL

The participants in the IT treatment group will be treated with intrathecal nicardipine injection through EVD or LP draining catheter.

Drug: Intrathecal Nicardipine

Control Group

SHAM COMPARATOR

The participants of the control group will receive no intrathecal nicardipine injection through EVD or LP draining catheter.

Other: No intervention

Interventions

First, 6 ml of cerebrospinal fluid is withdrawn from the EVD or LD catheter, and then 4 ml (4mg) of nicardipine is injected into the EVD or LD drain tube, followed by 2 ml normal saline solution, and then the EVD or LD tube is clamped for 2 hours, and then kept open as clinically necessary until the next dose (q12h) of medication.

Also known as: Treatment group
Intrathecal Treatment Group

A simulated "intrathecal administration" operation is performed by a dedicated physician who is unblinded to the group assignment, the EVD or LD tube is not opened, and no "drug" is given. The simulated administration process needs to be out of the patient's view (if awake patient) and out of the presence of study team personnel.

Eligibility Criteria

Age18 Years - 80 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Age 18-80.
  • Spontaneous SAH confirmed by head CT.
  • Saccular brain aneurysm is identified and treated, either surgically or endovascularly.
  • SAH Fisher grade \>1 or modified Fisher grade \>0.
  • EVD placed for acute hydrocephalus, or LD placed for draining bloody CSF as deemed necessary by the treating physician.
  • Any clinical scenario leading to the diagnosis of possible vasospasm, which includes:
  • Mean flow velocity of MCA \>120, or Lindegaard Ratio ( LR ) \> 3.
  • Any intracranial artery including MCA, ACA, PCA, and BA, TCD showed an upward trend of mean flow velocity for 2 consecutive days (\>25cm/s/day).
  • Clinical deterioration including mental status change (GCS score decrease \> 2) and focal neurological deficit unable to be attributed to other known neurological reasons.
  • Evidence of vasospasm on CTA or DSA, or ischemic change by CTP, MRI.
  • Within 14 days of onset of SAH.
  • Informed consent obtained from the patient or family member.

You may not qualify if:

  • Hunt-Hess Grade 5 or WFNS Grade 5 (no clinical improvement after EVD placement for acute hydrocephalus).
  • Bacterial or distal aneurysms without subarachnoid hemorrhage in the basal cisterns.
  • The treating physician determines that the culprit aneurysm has not been fully repaired, with a very high likelihood of rebleeding in the near term.
  • History of head trauma within the past 3 months.
  • Any recent brain disease within 3 months, such as tumors, stroke, epilepsy, vasculitis, arteriovenous malformation, hydrocephalus, etc.
  • History of psychiatric disorders or seizures within 3 months.
  • Severe concurrent medical conditions.
  • Pregnant women or those of childbearing potential with a positive urine or serum β-human chorionic gonadotropin (HCG) test.
  • Lactating women.
  • Life expectancy of less than 1 year prior to aSAH onset.
  • Pre-morbid mRS score \>1.
  • Participation in another randomized clinical trial that may confound the evaluation of this study.
