重型颅脑损伤患者自主神经功能障碍的临床分析

目的 探讨重型颅脑损伤患者自主神经功能紊乱综合征发生率、临床症状、发病危险因素及预后.方法回顾性分析2008年1月-2010年3月收治的142例重型颅脑损伤患者,比较自主神经功能障碍组和对照组(无自主神经功能障碍患者)的临床特征;采用Logistic回归分析自主神经功能障碍发病的危险因素;伤后6个月采用GOS评分分析其预后.结果142例患者中生存并成功随访94例,自主神经功能障碍患者16例(17%),且其在GCS评分、昏迷时间、ICU时间、平均住院时间等方面较对照组差异有统计学意义(P<0.05);自主神经功能障碍患者预后较差(P<0.05),与弥漫性轴索损伤(DAI)密切相关(OR=11.25,95%CI 7.65～16.54).结论 自主神经功能障碍在严重颅脑损伤患者中发生率较高,临床表现重,DAI增加其发作风险,此类患者多预后不良.

Abstract：

Objective To investigate the incidence, clinical symptoms, correlative risk factors and prognosis of dysautonomia in patients with severe traumatic brain injury. Methods A total of 142patients with severe traumatic brain injury treated from January 2008 to March 2010 were retrospectively surveyed to compare the clinical features of dysautonomia group and control group. Logistic regression was used to analyze the risk factors for dysautonomia. At 6 months post-trauma, the Glasgow Outcome Score (GOS) was used to measure the outcome. Results Of all the patients, 94 patients survived and were followed up. There were 16 patients ( 17% ) diagnosed as dysautonomia depended on clinical symptoms,with statistical difference in aspects of GCS, coma duration, ICU time and average length of stay (ALOS)(P < 0.05). The patients with dysautonomia tended to have poorer outcome ( P < 0.05 ) and showed a positive association with diffuse axonal injury (DAI) ( OR = 11. 25, CI 7.65-16.54 ). Conclusion Dysautonomia has high incidence and is usually severe in patients with severe traumatic brain injury,when DAI may contribute to its occurrence and result in poor prognosis.
