数字化外科：生物电阻抗测量技术辅助临床外科的操作**☆

生物电阻抗测量（Bioelectric Impedance Measurement Method,BEI）技术是生物医学工程学的一个飞速发展的领域,利用各种组织、器官不同的电导参数(阻抗、导纳、介电常数等),提取相关的生物医学信息,识别不同组织、器官的无损伤检测技术[1]。这种技术具有无创、廉价、安全、无毒害、操作简单和信息丰富等特点,具有广泛的应用前景。国际上已经开发出了多种基于BEI技术的无创、实时的测量和监控手段,部分产品已成功应用于辅助临床操作,值得关注

Advances in Bioelectric Impedance Measurement Assistance on Clinical Operation

BACKGROUND: Modern chirurgery technique claims less trauma and higher precision. Bioelectical impedance measurement technique, which transfers anthropometric tissue information to digital signal, can afford aid to clinical surgery discriminate different tissue and organ.OBJECTIVE: To summarize the clinical application of bioelectical impedance measurement technique for assistance of the chirurgery operation.METHODS: Literatures about application of bioelectical impedance measurement technique for the chirurgery operation were searched from Chinese Journal Full-text database and PubMed database, published from 1999 to 2009. Articles that qualitatively improve accuracy and curative effect evaluation using digital signal collection and analysis were analyzed.RESULTS AND CONCLUSION: The bioelectical impedance measurement technique is an ideal aided means, by the advantages of noninvasive, safe, durative monitoring, and repetitive use. With developing theory and methods of this technique, a large number of clinical trials have been conducted, which would enlarge its application
