自发性血气胸是指非创伤性原因引起的胸膜腔内积气和积血。近10年来,我们经治自发性血气胸12例,现结合文献探讨本病的诊断与治疗。1 临床资料 本组男9例,女3例;年龄21～42岁,平均32.4岁;发病至就诊时间为2小时至5天。诱因为剧烈运动6例、频繁剧咳3例,用力提重物2例,用力排便1例。血气胸位于右侧10例,左侧2例,9例病前无呼吸系统疾病史。12例中,11例起病急骤,并有患侧胸痛、胸闷及内失血表现;1例起病时症状不明显。其中4例血压偏低,1例休克;9例呼吸困难进行性加重,并有口唇紫绀;8例发热;12例均呈强迫半卧位,气管向健侧移位,患肺上部叩鼓音,下部叩实音。实验室检查:Hb60～90g/L,RBC1.9～2.9×10~(12)/L,3例WBC>10×10~9/L。X线检查均显示患侧有气液界面。B超探查有液性暗区;胸腔试穿均抽出不凝血性液体。均采用内科保守治疗。在输血、输液、抗休克及对症处理的同 Spontaneous pneumothorax refers to non-invasive causes of pleural cavity of the plot and hemorrhage. In the past 10 years, we have treated 12 cases of spontaneous blood pneumothorax, and now the literature to explore the diagnosis and treatment of the disease. 1 Clinical data The group of 9 males and 3 females; aged 21 to 42 years, mean 32.4 years; onset to treatment time is 2 hours to 5 days.
