目的 探讨膈肌运动过度致低氧血症病例的临床特征、诊断依据及治疗方法.方法 分析报告2例主要症状为呼吸过速致低氧血症,其中1例为肝脓肿,1例为膈下脓肿.结果 2例患者表现呼吸过速(＞40次/min),无急性呼吸窘迫.血气分析示动脉血氧分压(PaO2)＜55 mmHg,二氧化碳分压(PCO2)＜30 mmHg.胸部影像学检查示两肺野无典型病灶.治疗主要先予以对症干预治疗,纠正低氧血症后针对病因处理.结论 对呼吸过快所致的低氧血症应警惕膈下病变刺激膈肌运动过度所致,早期进行干预、诊断、综合治疗防治心肺并发症,是提高生存率的关键.%Objective To explore the clinical manifestations, diagnosis and treatment of acute hypoxemia induced by excessive diaphragmatic movement. Methods The main manifestation of these 2 cases was hypoxemia induced by tachypnea. The underlying diseases of them as follows: one case suffered from liver abscess and the another with subphrenic abscess. Results Two reported patients were presented with tachypnea but no progressive hypoxia. Arterial blood gas analysis demonstrated that PaO2 <55 mmHg and PaCO2 <30 mmHg. There was no typical lesion on chest CT scanning or X - ray examination. Treatment was mainly symptomatic for disease intervention after rectifying hypoxemia. Conclusion Physicians should be alert to the occurrence of tachypnea and hypoxemia caused by subphrenic pathological changes inciting excessive diaphragmatic movement. Early diagnosis and intervention and comprehensive treatment are the key for preventing and curing . Complications and improving survival rate of these patients.
