Brief summary

Robotic Assisted Evacuation of Subacute and Chronic Supratentorial Deep Hypertensive Intracerebral Hemorrhage for Accelerating Functional Rehabilitation (RESCUE-CHAIN): a Multi-center Randomized Controlled Trial

Detailed description

Background: Hypertensive intracerebral hemorrhage (HICH) is a devastating neurological disorder with high mortality and disability rates. Secondary injury following HICH may worsen motor function rehabilitation in subacute and chronic hematoma. Hematoma evacuation has the potential to reduce mass effect and mitigate the neurotoxic effects. A per-protocol analysis identified a significant functional improvement in patients with minimally invasive surgery with thrombolysis achieving end of treatment (EOT) goal ≤ 15mL. However, no surgical management of stabilized subacute or chronic HICH have been reported before. Therefore, we design this study in which we hypothesize this robotic assisted approach to hematoma EOT goal ≤ 15mL would accelerate functional rehabilitation in subacute and chronic HICH patients.

Interventions

PROCEDURERobotic Assisted Evacuation

On the day of surgery, the patient is placed in the prone position. After the Mayfield skull clamp is positioned to reduce interference, the videometric tracker of robot will automatically scan the preliminary markers to complete patient-to-image registration. Following the registration, the robotic arm will move on command according to the planned puncture trajectory and stop at a defined distance to the marked target point. The entry point is marked on the scalp along the puncture trajectory, then a scalp incision and burr-hole drilling will be performed. After penetrating the dura with unipolar electrocautery, a drainage tube will be gently inserted to the defined depth under the indication of the disinfected robotic arm. The liquefied hematoma will be withdrawn slowly by a 10 mL syringe.

Inclusion criteria

The inclusion criteria are HICH patients who: (1) are ≥ 18 and ≤ 75 years old of either gender; (2) have evidence of supratentorial, deep-seated on CT scan with a volume of between 15 mL and 30 mL; (3) are within 24 h of ictus (\<24 h between symptom onset and initial imaging); (4) have stable hematoma (hematoma growth\<5 mL) for at least 12 h after diagnostic CT; (5) have no brain herniation and no needs for emergency surgery (clinical decisions made by 2 attending neurosurgeons); (6) have had no previous surgery on HICH or traumatic brain injury; (7) have GCS\>8, NIH Stroke Scale (NIHSS)\>5, Modified Rankin Scale (mRS) 3-5, and FMA scale\<85; (8) fully understand the nature of the study and have signed informed consent. The

Exclusion criteria

are: (1) HICH caused by aneurysms, cerebrovascular malformations, tumors or trauma; (2) any pre-existing physical or mental disorder that could interfere with the functional assessment; (3) severe abnormal coagulation function, hematologic diseases or multiple hemorrhagic lesions; (4) excessive hematoma extending into the ventricular system with ventricular dilation; (5) concomitant diseases such as liver, kidney and heart failure; (6) rebleeding\>5 mL or with surgical indications before allocation; (7) poor adherence or other unsuitable situations for the trial as determined by the investigators; (8) pregnant female.

modified Rankin Scale (mRS) 0-2180 days after surgeryThe modified Rankin Scale (mRS) is a single item, global outcomes rating scale for patients post-stroke. It is used to categorize level of functional independence with reference to pre-stroke activities rather than on observed performance of a specific task.

It is used to categorize level of functional independence with reference to pre-stroke activities rather than on observed performance of a specific task.
Extended Glasgow Outcome Scale (eGOS)at 90- and 180-days after surgery.The GOS-E adds to the original 5 GOS categories, with 3 additional categories. The 8 categories are: Dead, Vegetative State, Lower Severe Disability, Upper Severe Disability, Lower Moderate Disability, Upper Moderate Disability, Lower Good Recovery, and Upper Good Recovery.
Evacuation rate of HICHat the first day after procedure, 30 days and 180 days during the follow-up period.the ratio of effective volume reduction to the initial volume
Barthel Index for Activities of Daily Living (ADL-BI)at 90- and 180-days after surgery.The Barthel Index (BI) measures the extent to which somebody can function independently and has mobility in their activities of daily living (ADL) i.e. feeding, bathing, grooming, dressing, bowel control, bladder control, toileting, chair transfer, ambulation and stair climbing. The index also indicates the need for assistance in care.
Fugl-Meyer Assessment (FMA)at 90- and 180-days after surgery.The FMA motor assessments for the upper (maximum score 66 points) and lower extremity (maximum score 34 points) are recommended as core measures to be used in every stroke recovery and rehabilitation trial.
Motor Assessment Scale (MAS)at 90- and 180-days after surgery.The MAS is comprised of 8 items corresponding to 8 areas of motor function. Patients perform each task 3 times and the best performance is recorded. Supine to side lying Supine to sitting over the edge of a bed Balanced sitting Sitting to standing Walking Upper-arm function Hand movements Advanced hand activities
NIH Stroke Scale(NIHSS)at 90- and 180-days after surgery.The NIHSS is a 15-item neurologic examination stroke scale used to evaluate the effect of acute cerebral infarction on the levels of consciousness, language, neglect, visual-field loss, extraocular movement, motor strength, ataxia, dysarthria, and sensory loss. A trained observer rates the ability to answer questions and perform activities. Ratings for each item are scored with 3 to 5 grades with 0 as normal, and there is an allowance for untestable items. The single patient assessment requires less than 10 minutes to complete. The evaluation of stroke severity depends upon the ability of the observer to accurately and consistently assess the patient
