wanting to switch to Burn ICU from LTC

I've been a BSN-RN for 1.5 years. I did med-surg for 6 months and am currently a charge nurse at a sub-acute facility. I worked as an aid in a PICU and MICU/SICUwhile in nursing school, and this kid who was a burn victim sticks out in my mind-I loved helping with his dsgs, etc. My question is-could I transition from LTC to any ICU, esp. burn ICU? Or have I limited myself?
