问题 单项选择题

男,25岁,因突发头晕、心慌、面色苍白就诊。查体:神志清醒、面色苍白,P 120/min。BP 70/ 50 mmHg,上腹部压痛,反跳痛。 B超提示腹腔积液,脾增大并不均质回声;腹腔穿刺抽出不凝血。9天前患者不慎自4米高处坠落,左侧身体落地,感左侧腹疼痛,休息2天后继续工作。最可能的诊断是

A.肝破裂

B.肝被膜下破裂

C.延迟性脾破裂

D.胃、十二指肠破裂

E.上消化道出血

答案

参考答案:C

解析:脾是腹内脏器中最易受伤的器官,脾破裂根据损伤的范围分中央型破裂、被膜下破裂和真性破裂。前两种因被膜完整,出血量受到限制,可无出血性休克的表现。此时仍有潜在的延迟性破裂可能性,如不注意绝对卧床休息,即使在微弱的外力作用下,可发生严重的内出血。延迟性脾破裂通常发生在受伤后1~2周。

     What is the best way to study? This is a very important question. Some of the Chinese students often

 study very hard for long hours. This is a good habit, but it is not a better way to study. I think an efficient

 (有效率的 ) student must have enough sleep, enough food and enough rest. Every day you need to go

 out for a walk. Every week you should visit some friends or some nice places. It's good for your study.
