摘　　要：本文分析了４０例重型颅脑外伤患者血气测定资料，发现低氧血症者占５７．５％，气管切开前后ＰａＯ２差异有显著性，有酸碱失调者占７７．５％，以呼碱最多，其次为代酸。提出重型颅脑外伤时，易引起体内酸碱失调，并是死亡的常见原因。讨论了各型酸碱失调的病因、病理机制及治疗方法。The data of determined blood gas in 40 cases of severe brain injury was analysed. Twenty-three of the 40 cases had hypoxemia, occurring in 77.5%. After tracheotomy, PaO 2 was significantly high. Thirty-one of the 40 cases had acid-base imbalance, occurring in 77.5%. The respiratory alkalosis was most common in the 40 cases. Severe brain injury can lead to acid-base imbalance through various factors such as respiratory, metebolic, pathologic and iatrogenic changes, and is the main cause of death. In this article, the types of acid-base unbalance, the etiology, mechanism and mathod of treatment are discussed.
