摘要：

【目的】通过建立一种重型颅脑外伤局灶低温治疗的方法 ,初步探讨其治疗重型颅脑外伤的疗效。【方法】采用自由落体撞击模型 ,设定假颅脑外伤模型组、颅脑外伤模型组及局灶低温组 (使用 2 5℃水降温 )。取损伤相邻区脑组织分别检测其水、Na+ 、K+ 、Ca2 + 含量。同时观察其病理改变。【结果】颅脑外伤模型组与局灶低温组神经元损伤数明显多于假颅脑外伤模型组 (P <0 .0 1) ,但局灶低温组神经元损伤数显著少于颅脑外伤模型组 (P <0 .0 1)。颅脑外伤模型组与局灶低温组水、Na+ 含量均较假颅脑外伤模型组显著增加 (P<0 .0 1) ,但局灶低温组水、Na+ 含量明显低于颅脑外伤模型组 (P <0 .0 1)。K+ 含量的变化呈现与水含量的变化相反的趋势。Ca2 + 含量的变化与水含量的变化无一致性。【结论】建立了一种重型颅脑外伤新型低温治疗方法 ,这种局灶低温治疗方法对于重型颅脑外伤的治疗可能具有重要价值
