About this trial

ASTIM is a multicenter, prospective, randomised, blinded end-point assessed trial, to investigate the efficacy and safety of treatment based on intracranial pressure monitoring in improving the prognosis of patients with aneurysmal subarachnoid hemorrhage.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Confirmed diagnosis of aSAH: presence of SAH symptoms, confirmed by CT scan or lumbar puncture. CTA or DSA confirms ruptured intracranial aneurysm (IA) as the cause. Decision made to perform craniotomy clipping or endovascular treatment within 72 hours aiming for a single procedure to cure the bleeding artery aneurysm;

Age ≥ 18 years;

The onset of symptoms should occur within 72 hours;

The Hunt-Hess grade is between 2 and 4, and the CT imaging findings correspond to a modified Fisher grade of 2 to 4.

Disqualifiers

Pregnancy or lactation period;

Patients presenting with bilateral dilated pupils upon admission;

Patients with concurrent tumors, hemorrhagic diseases, or other severe underlying conditions (such as chronic obstructive pulmonary disease, multiple organ dysfunction syndrome, severe diabetes mellitus, congestive heart failure, and chronic kidney disease);

Patients with a history of brain disorders or previous brain surgeries;

Trial design

Design model

Parallel

Treatments tested in this trial

  • Intraventricular intracranial pressure monitoring

    Device

    The postoperative management of ICP is guided by quantifiable Intraventricular ICP parameters. The remaining treatments are consistent with those in the control group.

Treatment groups

372 Participants
are divided into 2 treatment groups
Group A: aSAH treatment based on Intraventricular ICP monitoringExperimental treatment 1 intervention
Group B: aSAH treatment without Intraventricular ICP monitoringNo intervention 0 interventions

Trial outcomes

Primary outcomes

1

The rate of good neurological functional prognosis

The proportion of patients with modified Rankin Scale (mRS) scores 0-2. The mRS is an ordinal hierarchical scale ranging from 0 to 6, with higher scores indicating more severe disability. A mRS ≤ 2 indicated a good clinical outcome, and a mRS 5-6 indicated a poor clinical outcome.

Time frame
90 days

Secondary outcomes

1

The rate of good neurological functional prognosis

Proportion of patients with modified Rankin Scale (mRS) scores 0-2

Time frame
30 days, 180days
2

The rate of good prognosis by Glasgow Outcome Scale-Extended (GOS-E)

The GOS-E is an ordinal hierarchical scale ranging from 1 to 8, with lower scores indicating more severe disability.

Time frame
30 days, 90 days, 180days
3

Mortality

Proportion of patients who died.

Time frame
30 days, 90 days, 180days
4

Incidence of VP shunt-related hydrocephalus

Incidence of hydrocephalus requiring ventriculoperitoneal shunt within 90days.

Time frame
90 days

Other outcomes

1

Incidence of intracranial infection

The cerebrospinal fluid culture demonstrates positive findings for pathogenic bacteria, or the cerebrospinal fluid exhibits an elevated count of more than 1000 white blood cells with a predominance of polymorphonuclear cells, accompanied by decreased glucose levels and increased lactate levels in the cerebrospinal fluid.

Time frame
90 days
2

Incidence of bleeding from puncture site

This refers to intracranial bleeding resulting from ventricular puncture, which can be confirmed via a head CT scan.

Time frame
90 days
3

Incidence of poor healing in surgical incisions

This encompasses infection and suppuration at the ICP incision site, potentially impeding proper wound closure.

Time frame
90 days
