Head injury is still a major cause of death and disability despite the implementation of aggressive methods of evaluation and intensive care. It is our feeling that if further gains are to be made in improving patient outcome, new efforts must be directed at the basic pathophysiologic processes involved in severe head injury. Based upon extensive data obtained in our laboratories, we have chosen to target our therapeutic efforts at the damaging consequences of oxygen radicals on the cerebral vasculature. Specifically, the hypothesis is that the action of free radicals on the cerebral vasculature contributes significantly to the morbidity and mortality of severe head injury, and quenching of free radicals with PEG-SOD* can improve the outcome in patients with severe head injury. To prove this hypothesis, we will conduct a prospective, randomized, double-blind, Phase III trial. The patients will be divided for the Phase III trial into 2 groups: (1) a control group, and (2) a group treated with PEG-SOD. The efficacy of this agent will be measured by the Glasgow Outcome Score (GOS) at one year, as well as by other measures of outcome, specifically the Disability Rating Scale (DRS) and the Los Ranchos Amigos Outcome Scale. Other measures of efficacy will also be used; these include dynamic intracranial pressure (ICP) monitoring coupled with measurements of vascular reactivity, the neurologic exam, and biochemical assays of appropriate products of lipid peroxidation.

尽管头部受伤仍然是死亡和残疾的主要原因 实施积极的评估和重症监护方法。 它 我们的感觉是，如果要在改善患者状况方面取得进一步的进展 结果，新的努力必须针对基本的病理生理学 涉及严重头部损伤的过程。 基于大量数据 在我们的实验室获得的结果，我们选择了我们的治疗目标 努力解决氧自由基对大脑造成的破坏性后果 脉管系统。 具体来说，假设是自由的作用 自由基对脑血管系统的作用显着 严重颅脑损伤的发病率和死亡率以及自由猝灭 含有 PEG-SOD* 的自由基可以改善严重头部患者的预后 受伤。 为了证明这个假设，我们将进行前瞻性研究， 随机、双盲、III 期试验。 病人将被分开 将 III 期试验分为 2 组：(1) 对照组，(2) 对照组 用PEG-SOD处理。 该药剂的功效将通过以下方式来衡量 一年的格拉斯哥结果评分 (GOS)，以及其他衡量指标 结果，特别是残疾评定量表 (DRS) 和洛斯兰乔斯 朋友结果量表。 还将使用其他功效衡量标准；这些 包括动态颅内压 (ICP) 监测以及 血管反应性测量、神经系统检查和生化检查 脂质过氧化的适当产物的测定。
