Clinical Trial Summary

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.


Description:

Subarachnoid hemorrhage (SAH) is a severe type of cerebral hemorrhage, characterized by a high mortality and disability rate, approximately 85% of SAH cases are attributed to ruptured intracranial aneurysms (RIAs), which is called aneurysmal SAH (aSAH). Improving the prognosis of patients with aSAH has become a pressing and significant issue. The rupture of an aneurysm results in a significant amount of blood entering the subarachnoid space, triggering an increase in intracranial pressure (ICP). This escalated ICP, coupled with the compression from the hematoma, severely impairs brain tissue function, leading to a cascade of irreversible neurological impairments, such as abnormal blood pressure, respiratory arrest, and cardiac arrest. Systematic reviews and meta-analysis found that the incidence rate of elevated ICP (ICP > 20mmHg) in post-aSAH patients was 70.69%, with higher levels (according to the Hunt-Hess scale, WFNS scale, or modified Fisher grade) being more prevalent for increased ICP. The utilization of Intraventricular ICP monitoring in patients with aSAH offers the advantage of obtaining real-time, accurate data on intracranial pressure, enabling more precise and timely control of cranial pressure. However, there is a dearth of high-level randomized controlled trial evidence supporting the use of ICP in the treatment of aSAH. Given the potential utility of ICP monitoring in aSAH management and its current lack of high-level evidence in evidence-based medicine, we intend to pursue the research.

Enrollment 368
Est. completion date December 30, 2026
Est. primary completion date June 30, 2026
Accepts healthy volunteers No
Gender All
Age group 18 Years to 70 Years
Eligibility Inclusion Criteria: - The diagnosis of aSAH is established through the presence of SAH symptoms, confirmed by computed tomography (CT) scan or lumbar puncture, and further substantiated by cerebral angiography (CTA) or digital subtraction angiography (DSA) to identify the rupture of an intracranial aneurysm as the etiology. It is resolved to perform microsurgical clipping or endovascular therapy within 72 hours of the acute phase, along with the treatment of the ruptured aneurysm in phase I stage (excluding patients with exacerbated SAH due to intraoperative aneurysm rupture and occlusion of feeding arteries). - The age ranged from 18 to 70 years; - The onset of symptoms should occur within 72 hours; - The GCS score should range from 6 to 12 points; - Obtain the consent of the patient and their family members, and have them sign an informed consent form. Exclusion Criteria: - Pregnancy or lactation period; - Patients presenting with bilateral dilated pupils upon admission; - Patients lacking spontaneous breathing or suffering from shock; - 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; - Hemorrhage attributable to causes other than aneurysm; - Aneurysmal rupture bleeding concurrent with moyamoya disease; - Other underlying conditions that impact prognosis; - Patients volunteering for ICP monitoring; - Participants in other ongoing clinical trails; - Other circumstances deemed inappropriate for inclusion (to be determined by two physicians).
