※ 引述《yalosun (leo)》之銘言：
: P.17第35題
: 貝塔補洛克的解釋很合理沒錯
: 可是題幹並沒有說有氣喘的情況
: 不知道有沒有人覺得還是要選D
1.You should not consume or use alcohol, caffeine, or tobacco (or any other
source of nicotine) for 24 hours before the test.
2.Do not eat anything for at least three hours before the test.
3.You may be instructed to stop "certain medications" before the test.
4.At the test site, blood pressure is measured, and ECG leads are attached to
your chest, arm, and leg.
5.An IV line is started in your arm.
from http://www.answers.com/topic/myocardial-perfusion-scan
-->依據此 我想b-blocker會不會是"certain medications" 因為這個副作用應會和
dipyridamole加成
在
http://www.crstlukes.org/documents/Imaging%20Services%20Procedures/
Myocardial%20Perfusion.pdf 這裡找到
Patients who are regularly taking beta-blocker medication
(i.e., Lopressor, Tenormin, etc.) should not take them for 24 hours
before the exam. This should be discussed with your doctor.
-->這個簡報也附了一張紀錄表 裡面有停止咖啡因和Beta-blocker的時間
個人猜想:咖啡因的停止時間是否用來給醫師參考數據時的信任度
而Beta-blocker的停止時間是用來給核醫科醫師排除嚴重副作用的用途呢??
所以偏向選(D) 畢竟喝了含咖啡因的飲料頂多會讓藥物效果下降
還不至於會有嚴重呼吸道副作用吧~
另外補充找到的
If you are pregnant or suspect that you may be pregnant, you should notify
your physician due to the risk of injury to the fetus from myocardial
perfusion scan.
If you are lactating, breastfeeding, you should notify your physician due to
the risk of contaminating breast milk with radionuclide.
Radiation exposure during pregnancy may lead to birth defects.
-->哺乳和懷孕都要特別小心~~

對了 那如果這樣的話 p49第7題答案是否選(1)較佳呢??
供大家參考囉~~
