I like PICU because it still includes the peds...with extra and interesting challanges
Out of school, I worked for 2 1/2 years on pediatric med/surg floors in Children's hospitals, 6 months of that I was travel RN. In the beginning, I felt like I was learning a ton every day, there was a lot of variety, interation with the kids and families, etc. My first two years, we had the luxury of talking amongst ourselves and picking our patient assignments (I see how rare that is now). I found myself actually picking the sickest and most involved of the patients on top of my other busy assignments...because I really enjoyed the intellectual stimulation. This may sound morbid to anyone but a PICU nurse, but I actually enjoyed being the nurse who helped that kid who was starting to go downhill that day on the floor...nobody else really wanted to.
While there's always something new to learn, I found myself getting really bored on the floors, even being a travel RN. I ended up moving and alas, no med/surg position...but tons of PICU. I couldn't believe it! I had found my niche, and didn't even know it would be. (I had interviewed for PICU as a new grad and the manager scared me to death...never thought I'd give it a try after that)
I love the chaos, the highly increased learning curve, the invasive procedures, helping families in times of intense stress, actually finding that the docs find the nurses' opinions and thoughts imperative to patient care in the PICU. When children die or are close to the brink, you're the one the families can lean on in their suffering. Or you're the instrument that helped save that child's life. I've got a very one-track mind, I enjoy being able to focus all my energies on one patient, one family...instead of the multitudes.
Just one of the disadvantages is that the PICU can take it's toll on you emotionally. I guess I wasn't prepared for some of the social situations that you'll encounter. I knew that in peds you not only take care of a patient, you take care of the whole family. In PICU, you can take care of families who are severely stressed, financially in ruins, slightly neurotic, potentially abusers or negligent, agressive, and on and on. In PICU, you can't just come in do your patient care. Sometimes I spend a lot of my shift talking on phone to families, smoothing things over with them because I can't get a single doctor with a second to talk with them, teaching, supporting... I leave some days with my emotions completely tapped out. It's rewarding, but exhausting at times.
Anyway, I think it's really helpful to know your skills, your likes and dislikes, what kind of nurse you are before venturing into the PICU. You might potentially consider shadowing a nurse for a day in the PICU to get a good perspective. Good luck to you as you search out the possibilities.
