美国Integra公司研制出脑外伤患者神经监测NeuroSensor系统
 
一种新型神经监测系统可以同时测量脑外伤患者的大脑血流以及颅内压。这种系统已经得到了美国食品和药品管理局的批准。

这种被称作NeuroSensor（“神经感受器”）的系统操作简便，临床医生只要将单个导管插入一个不起眼的螺栓中，就可以同步测量患者的大脑血流和颅内压。这个系统允许外科医生实时监测相关的生命体征，允许持续定量检测患者脑部缺血的风险，允许在外伤或者脑外科手术等脑实质创伤之后，直接检测颅内压。检测系统使用激光多普勒流式仪技术测量脑部血流，而使用微电子机械系统（microelectromechanical system，MEMS）测量颅内压。通过检测可以导致颅内压升高的病变，比如大脑血流的某些特定变化，从而可以预防进一步的脑损伤，或者将这种损伤限制在最小范围内。

美国新泽西州Integra生命科学储备公司（Plainsboro, NJ, USA）高级副总裁Deborah Leonetti说：“我们的目标是提供在线和实时的多峰形性监测作为监测标准，这促使了神经监测系统的研发，我们为能够提供这种治疗和监测神经外伤和脑血管疾病的尖端技术而感到十分自豪。”

Neuromonitoring for Brain-Injured Patients

A new neuromonitoring system measures both cerebral blood flow (CBF) and intracranial pressure (ICP) in brain-injured patients. The system has been cleared by the U.S. Food and Drug Administration (FDA).

Called NeuroSensor, the system is easy to use, allowing clinicians to obtain simultaneous measurements of a patient’s CBF and ICP through the use of a single catheter inserted through a low-profile bolt. The system provides relevant measurements for a surgeon on a real-time basis, allowing for continuous qualitative monitoring in patients at risk of cerebral ischemia and for the direct monitoring of ICP in intraparenchymal applications following injury or neurosurgical procedures. The sensor measures CBF using laser Doppler flowmetry technology, while ICP is measured by a microelectromechanical system (MEMS). By detecting the conditions that lead to increased ICP, such as certain changes in CBF, further injury to the brain may be prevented or limited.

“Our goal is to provide online and real-time multimodality monitoring as the standard of care,” noted Deborah Leonetti, senior vice president of marketing for Integra Lifesciences Holdings Corp. (Plainsboro, NJ, USA; www.integra-ls.com), which developed the neuromonitoring system. “We are very proud to offer this cutting-edge technology for the treatment and care of patients with neurotrauma and cerebrovascular disease.”
