Hi fellow nurses!I am a new grad one month into my first job at the neuro ICU. I am still finding myself confused about blood pressure as it relates to neuro compared to the rest of the body. In conditions such as subarachnoid hemorrhage, I've noticed that it's important to keep their blood pressures high, but at the same time they are given nimodipine to prevent vasospasms. Doesn't nimodipine also lower/control blood pressure and if so, why are we vasodilating them while at the same time wanting to keep them hypertensive? I guess I'm thinking of it in terms of someone having hypertension as a condition by itself without neuro involvement, so that's skewing my reasoning on this concept. My preceptor wasn't sure of the answer, along with the charge nurse, and when I asked one of the doctors, he just confused me more. Can anyone explain it better? What is the role of blood pressure in the brain for someone with a neuro condition? Do they have to be hypertensive or hypotensive and how does that relate to the cerebral prefusion?If anyone can help me grasp this concept, I'd really appreciate it :)Thanks a bunch!!!
