Our hospital has recently started doing heart scans. Since I am new to radiology, I would like to hear from nurses with experience in this test. We currently give 100mg Lopressor po 2 hours prior to scan to lower HR. If this does not lower HR to less than 65, we give IV Lopressor 5 mg Q5 minutes X3 doses. Recently, we had a patient with known cardiac prob's (MI and stents 5 years ago), who was already on a beta blocker, so he did not take the po Lopressor we normally give. We ended up giving him 3 doses of IV (15 mg total). The problem is, his HR was still in the high 60's, although it REALLY dropped his BP (80/50) post procedure!!
We do not have a "recovery room" so I monitored him in our treatment room for 45 minutes. Of course his BP was better, and he went home. I have 2 questions: Does anyone use anti-anxiety meds(Ativan, Valium, etc) po prior to scan to lower HR? 2nd question: Does anyone use po Calcium channel blockers for someone with asthma instead of a beta blockers? When I asked one of our cardiologists, he said he would still use a beta blocker on someone with asthma because it "is in and out so quickly". By the way, when we scan, I am the only nurse and I have a radiologist with me and the tech. Our radiologist reads the heart scan. Is this common practice else where? Thanks in advance!

we give lopressor 15mg ivp over 5 minutes, wait 15 minutes, if the hr is not down, and bp ok, we push 35mg of lopressor in 7 minutes. 99.9% of the time if the first 15mg doesn't bring it down the additional 35mg won't do it either. it's just me and the ct tech. no radiologist, no cardiologist. our cardiologists read the heart scans. i also push versed & sublimaze for conscious sedation. the interventional radiologist is present for sedations. i personally think iv anti-anxiety meds would work much better for the heart scans.
