问题 单项选择题 A1型题

男性,75岁,咳嗽、痰血5个月。既往慢性支气管炎病史15年,登2层楼感气急。体格检查:两肺呼吸音粗,散在细湿啰音。胸片:右肺门增大,见-5cm×4cm肿块影。纤维支气管镜检查:右肺主支气管管口被新生物完全堵塞。肺功能检查:肺活量1800ml,占预计值45%,残气量900ml,占肺总量45%。血气分析:pH7.414,氧分压10.5kPa(79mmHg)。下列治疗错误的是()

A.中医中药治疗

B.营养支持治疗

C.化学治疗

D.放射治疗

E.右侧全肺切除

答案

参考答案:E

解析:该患者的诊断应该比较明确的是中央型肺癌,病史中多年慢性支气管炎史,以及登2层楼即感气急,表明肺通气贮备功能不佳。肺功能检查肺活量仅占预计值45%,而残气明显增高。血气检查表明低氧血症的存在,故该患者不能耐受全肺切除术。
