问题 患者男性,65岁,呼吸困难,心前区不适;查体有奇脉、颈静脉怒张;听诊心音遥远;X线示心影增大呈"烧瓶"状;超声提示心包积液 超声测量心包腔无回声区宽4.5mm,且局限于房室沟附近的左室后下壁区域,估测心包积液量为
选项 A.<50ml B.50~100ml C.100~300ml D.300~500ml E.>500ml
答案 B
解析 :心包积液的定量:①微量心包积液(<50ml):心包腔无回声区宽2~3mm,局限于房室沟附近左室后壁;②少量心包积液(50~100ml):心包腔无回声区宽3~5mm;③中量心包积液(100~300ml):心包腔无回声区宽5~10mm;④大量心包积液(300~1000m1):心包腔无回声区宽10~20mm,可出现心脏摆动;⑤极大量心包积液(1000~4000ml):心包腔无回声区宽20~60mm,心脏出现明显摆动

错误啦!

错误信息

  • 消息: [程序异常] : MISCONF Redis is configured to save RDB snapshots, but it's currently unable to persist to disk. Commands that may modify the data set are disabled, because this instance is configured to report errors during writes if RDB snapshotting fails (stop-writes-on-bgsave-error option). Please check the Redis logs for details about the RDB error.
