Comparison of the Application in Traumatic Brain Edema Between EIT and Non-invasive ICP Monitoring (EIT)

2014年1月2日 更新者：Xijing Hospital

Comparison of the Application in Traumatic Brain Edema Between Electrical Impedance Tomography and Non-invasive Intracranial Pressure Monitoring

Brain edema is the main reason for the disability and lethality in traumatic brain injury, which is the most difficult part of emergency rescue. Recently, there is no medical equipment to monitor the early brain edema in clinic. We have found that Electrical impedance tomography (EIT) can perform the real-time and bedside monitoring of brain electrical impedance after single-dose mannitol treatment, which may be a new strategy for the surveillance of brain edema. In this study, we would like to compare the application in traumatic brain edema between EIT and Noninvasive intracranial pressure (ICP) monitoring, including the progress of brain edema, the relationship between impedance and ICP, and the improvement for the patients' prognosis. EIT would probably be a new image strategy for the treatment of traumatic brain injury.

研究衡量的是什么？

主要结果指标

结果测量
措施说明
大体时间
brain electrical impedance
大体时间：From the 1st day (enrollment) to the 7th day
After the patients' enrollment, the electrodes would be placed properly and the continuous monitoring of brain impedance just be started.
From the 1st day (enrollment) to the 7th day

次要结果测量

结果测量
措施说明
大体时间
Glasgow coma scale(GCS)
大体时间：on the 0 day of the study
The scale is composed of three tests: eye, verbal and motor responses. The three values separately as well as their sum are considered. The lowest possible GCS (the sum) is 3 (deep coma or death), while the highest is 15 (fully awake person).
on the 0 day of the study
demographic characteristics at baseline
大体时间：on the 0 day of the study
The demographic data include age, gender, injuries reason, time from injuries, and so on.
on the 0 day of the study
kidney function examination
大体时间：On the 1st day, 3rd day, 5th and 7th day
There are three main indicators: blood creatinine, urea nitrogen, and uric acid. These indicator are used as a monitor of the kidney safety.
On the 1st day, 3rd day, 5th and 7th day
Physiological and pathological reflex check
大体时间：on the 1st and 7th day
on the 1st and 7th day
muscular strength and tension test
大体时间：on the 1st and 7th day
There are 6 grades in muscular strength test. And muscular tension test was referred to Modified Ashworth scale.
on the 1st and 7th day
non-invasive intracranial pressure
大体时间：From the 1st day (enrollment) to the 7th day
This equipment can continuously monitor the change of intracranial pressure since the patients' enrollment.
From the 1st day (enrollment) to the 7th day
brain CT scan
大体时间：On the 1st day (enrollment), and 7th day
Brain CT scan is applied to monitor the degree and progress of the brain change after the medication of mannitol.
On the 1st day (enrollment), and 7th day
Disability Rating Scale (DRS)
大体时间：on the 1st day (enrollment), seventh day after hospitalization
The DRS includes measures of eye opening, verbalization, and motor response (derived from the Glasgow Coma Scale); cognitive understanding of feeding, dressing, and grooming; degree of assistance and supervision required; and employability. Scores range from 0 to 29, with higher values indicating greater disability.
on the 1st day (enrollment), seventh day after hospitalization
glasgow outcome scale(GOS)
大体时间：the patients were discharged or the 7th day after hospitalization
GOS includes 5 grades: Dead, Vegetative state, Severe disability, Moderate disability, Good recovery.
the patients were discharged or the 7th day after hospitalization
