Then the VmMCA of craniocerebral injury cases was comparedwith the VmMCA of 40 healthy adults, and comparison was made between the groupsof subarachn

The

The severity of cerebral vasospasm is proporti onal to the patients conditions.ConclusionsTCD can be a timely, accurate and non_ invasive way to detect cerebral vasospasm following craniocere

7、流,使脑循环减慢,导致 脑灌注不足。因此,及早诊断脑血管痉挛,将有助于提高治疗效果。我们自 2008年1月至2009年6月对80例颅脑外伤成人患者进行TCD监测,测定其大脑中动脉血流速度 ,探讨脑血管痉挛的改变规律及与病情的关系,现报告如下。 1 资料与方法 1.1 一般资料: 随机选择自2008年1月至2009年6月的80例颅脑外伤住院成人患者作为颅脑外伤组,入选患者 符合以下条件:(1)年龄18岁,因颅脑外伤后24小时内入院治疗;(2)未合并系统性损 伤如胸腹部严峻创伤等,无创伤性休克;(3)未合并严峻心功能不足、心肌缺血及急慢性 肝肾功能衰竭;(4)未合并中枢神经系统及全身感染;(5)近
8、三个月内未服用钙离子拮抗 剂者。其中男46例,女34例,年龄1849岁,平均32.5岁。入院后均行头颅CT检查,解除 无法供应致伤缘由、受伤时间的患者。患者颅脑外伤程度按GCS评 分2为轻度39例,中度22例,重度19例。另取同期健康成年体检人员40例作为对 照组,其中男25例,女15例,年龄1947岁,平均31.2岁,均无颅脑损伤,无高血压 及心脏病史、无贫血和脑血管病史。在颅脑外伤组中,43例患者头颅CT或腰穿显示有蛛网膜 下腔出血(SAH),作为合并SAH组,其他患者作为未合并SAH组。 1.2 方法: 80例患者入院第1、2、3、4、5、6、7、14天行TCD检测大脑中动脉平均血流速度
