问题 单项选择题

在室间隔缺损修补术的体外循环中如发现灌注压低,左心有大量鲜红色回血,应考虑

A.合并房间隔缺损

B.合并肺动脉瓣关闭不全

C.合并二尖瓣关闭不全

D.合并动脉导管未闭

E.合并三尖瓣关闭不全

答案

参考答案:D

解析:当室间隔缺损合手动脉导管未闭 (PDA)而术前未发现,在体外循环下修补室缺时,主动脉灌注的氧合血会通过PDA回流入心内。其他的合并畸形均与回血无关。

How often do you let other people's nonsense change your mood? Do you let a bad driver,impolite waiter,rude boss,or an insensitive employee  36 your day?
One day I was in a taxi and we headed  37  the airport.We were driving in the  38 lane when suddenly a black car drove out of a parking space right in front of us.My taxi driver slammed on his  39 ,slid sideways,and at the very last moment our car stopped and  40  the other car by just inches!The driver of the other car looked around and started  41  at us.
My taxi driver just  42 and waved at the guy.And I mean he was really  43 .So I asked,“Why did you just do that?This guy almost ruined your car and sent us to the hospital!”This is when my taxi driver taught me what I now call“The Law of the Garbage Truck”.
He explained that many people are like garbage trucks.They run around full of   44 ,full of frustration,full of anger,and full of disappointment.As their garbage  45  up,they need a place to dump it and sometimes they'll dump it on  46 .Don't take it personally;Just smile, wave,wish them well,and move on.
Believe me.You'll be  47 .Don't take their garbage and  48 it to other people at work, at home,or on the streets.Life's too short to wake up in he morning with  49 . The mark of your success is how quickly you can refocus on what's   50  in your life,Roy Baumeister,a psychology researcher from Florida State University,found in his extensive research that you  5l bad things more ofter than good things in your life,you store the bad memories more easily,and you  52 them more frequently.
Therefore,love the people who treat you right and ignore the ones who don't.Life is ten percent what you make it and  ninety percent how you  53  it!
When you follow“The Law of the Garbage Truck”, you take back control of your life! You make room for the good by  54 go of the bad.Have a marvelous,garbage-free day! The seeds you plant today  55 the harvest you will reap tomorrow.
