atropine oph for excessive secretions

I had a pt that suffered anoxic brain injury and had a trach, and was now stable in our stepdown unit. He became tachycardic last night and also had increased blood pressure, as well as increased agitation, on my shift. When I did neuro checks, I found his eyes to be dilated and unresponsive to light, bilaterally. After a few hours of increasing agitation and elevated SBP (from around 145 increased to around 180), I called in the rapid response team. The patient was scheduled for a stat CT of the head, but his vital signs eventually returned to normal and it was postponed until the next shift, so I never discovered if there had been any changes on his CT exam.

My question is this: I saw that this pt had received atropine oph sublingual for excessive secretions almost 12 hours before on the previous shift. Does anyone know if these atropine drops could have caused the patient's eyes to be dilated and unresponsive for this long? If so, it really confused his neuro exam, especially taken together with his increased vital signs and agitation. I also wondered if the nurse that administered these drops applied them to the eyes rather than sublingual, since the pt was NPO due to a trach, and also the order read: atropine "oph", but also stated "route: sl".

Just wondering what any experienced nurses out there might think of this situation.
Atropine inhibits parasympathetic influences in the body. Atrope will cause mydriasis.

So I looked up mydriasis and it does sound like the atropine could be what caused it - but I agree, that's a long time afterwards. I would love to hear more thoughts on this, as I know very little about this . . .

from the package insert...........duration of action:long-acting; effects on accommodation may last 6 days; {48} mydriasis may persist for 12 days. {48}read more: http://www.drugs.com/mmx/isopto-atro...#ixzz0x6jwln1fi would suspect the eye gtts were not given sl

As a hospice nurse I have administered atropine gtts SL to treat excessive orolaryngeal secretions. I agree that in this case it appears likely that the drops were administered to the eyes.

Atropine..."hot as a hare, mad as a hatter, dry as a bone, blind as a bat."

This is just the first thought that came into my mind when I first read your post: does your patient have seizures?Dilated pupils, agitation, tachycardia with an associated increase in blood pressure reminded me of seizure symptoms to watch for in the RSI'd patient.Of course that would depend upon many questions I have about your patient, but it's a thought....what did your RRT conclude?
