流行性乙型脑炎的血气检测分析

Detection and analysis of blood gas in epidemic encephalitis B patients

目的探讨流行性乙型脑炎酸碱失衡及低氧血症的规律。方法对49例临床上不同类型的流行性乙型脑炎于临床上不同的发展阶段进行血气分析。结果68例次血气分析中有55例次伴酸碱失衡,占81%,呼吸性碱中毒的几率最高,占41．4%。死亡组酸碱失衡与低氧血症的发生率明显高于存活组。结论流行性乙型脑炎酸碱失衡与低氧血症的发生率与疾病的严重程度密切相关,可作为判断预后的重要指标之一。

Objective To investigate the ride of acid- base imbalance andhypoxemia in patients with epidemic encephalitis B. Methods Blood gas analysis of 49 epidemic encephalitis B patients was made at different clinical period. Results Acid - base imbalance was observed in 81% of the patients. The morbidity rate of acid - base imbalance and hypoxemia in death group was obviously higher than that of survival group （ P 〈 0.05）. Conclusion The morbidity rate of acid - base imbalance and hypoxemia in epidemic encephalitis B patients is correlated with the severity of the disease and it can be taken as one of the important criteria for judgment of prognosis.
