BIATICH: The Effect of BIA Monitoring of Brain Edema on the Neurological Prognosis of Supratentorial Massive ICH
Study Details
Study Description
Brief Summary
Spontaneous cerebral hemorrhage (SICH) is a hemorrhage caused by the rupture of a blood vessel within the brain parenchyma that is non-traumatic. Its rapid onset and dangerous condition seriously threaten human health; it accounts for about 15% of strokes and 50% of stroke-related mortality. Hunan Province is recognized as one of the high incidence areas of cerebral hemorrhage in the world; according to statistics, the direct economic loss caused by cerebral hemorrhage in Hunan Province is more than 1 billion yuan per year, which should be paid great attention. A 30-day follow-up study of large-volume cerebral hemorrhage (defined as supratentorial hemorrhage greater than 30 ml, infratentorial greater than 5 ml, and thalamus and cerebellum greater than 15 ml) found that the morbidity and mortality rate of ICH with hemorrhage of 30-60 ml was as high as 44-74%, while the morbidity and mortality rate of ICH with hemorrhage of <30 ml was 19% and that of >60 ml was 91%. According to studies, the occurrence of hematoma occupancy and malignant cerebral edema in large-volume cerebral hemorrhage can lead to secondary malignant intracranial pressure elevation and subsequent secondary brain injury, which are the main factors of high morbidity and mortality and poor prognosis in patients with large-volume cerebral hemorrhage. Clinical monitoring and management is the key to treatment, and despite aggressive surgical treatment and anti-brain edema therapy, a large number of patients progress to malignant brain edema disease, leading to poor outcomes. Therefore, this project intends to conduct a multicenter clinical trial of non-invasive monitoring of large volume cerebral hemorrhage on the curtain in the Hunan region to explore the impact of non-invasive brain edema monitoring management based on bioelectrical impedance technology on patient prognosis; and to explore early biomarkers of malignant brain edema through metabolomic analysis and the mechanism of malignant brain edema occurrence through multi-omic analysis to provide data support for the clinical treatment application of malignant brain edema.

Detailed Description
Intracranial pressure and cerebral edema monitoring are commonly used neurological monitoring modalities in neurocritical conditions worldwide. There remains uncertainty in the prognosis of neurological function in patients with traumatic and non-traumatic brain injury with invasive intracranial pressure monitoring, non-invasive intracranial pressure monitoring and cerebral edema monitoring modalities, and differences in clinical practice between the two tests in patients with large volume cerebral hemorrhage. The objectives of this study were to explore the differences between non-invasive brain edema monitoring based on BIA technology (Chongqing Born-Fruk Medical Equipment Co., Ltd., Chongqing, China) and invasive intracranial pressure monitoring, and whether non-invasive brain edema monitoring based on BIA technology is more beneficial for the long-term prognosis of patients with episodic large-volume cerebral hemorrhage, whether there are fewer complications, and whether such monitoring measures are more acceptable in clinical practice. The trial is a prospective, randomized, open-label, controlled, multi-clinical center trial; the sample size was calculated based on previous studies to include a total of approximately 776 cases, and is expected to include more than 20 clinical institutions with extensive experience in the treatment of large volume cerebral hemorrhage in Hunan Province, China. Patients diagnosed with supratentorial parenchymal cerebral hemorrhage (hemorrhage volume ≥ 30 ml according to the Coniglobus formula ) by CT examination within 48 hours of onset were included, and informed consent was provided to patients who met the enrollment criteria. The included cases were divided into surgical and non-surgical groups according to the guidelines for the treatment of cerebral hemorrhage and taking into account the patient's condition, the physician's decision and the family's choice of whether to receive surgical treatment (craniotomy or minimally invasive surgery) or conservative treatment, thus avoiding the ethical risk of large-volume cerebral hemorrhage. Enrolled non-surgical cases were randomly assigned 1:1 to the BIA non-invasive cerebral edema monitoring group and theImaging clinical examination（ICE) group. Cases that received surgical treatment were divided into two subgroups, the craniotomy group and the minimally invasive surgery group, depending on the type of surgery received, and of the two subgroups were randomly assigned in a 1 : 1 : 1 ratio to the invasive ICP monitoring group, the BIA technique noninvasive brain edema monitoring group, and the Imaging clinical examination（ICE） group. All the related investigative organization and individuals will obey the Declaration of Helsinki and Chinese Good Clinical Practice standard. A Data and Safety Monitoring Board (DSMB) will regularly monitor safety during the study.The trial has been approved by Institutional Review Board (IRB) and Ethics Committee(EC) in Xiangya Hospital Central South Uniersity.
