I was wondering if anyone knows what is considered the most risky,dangerous as well the painful surgery? I'm going over my notes for the NCLEX and I keep running into all those contraindications for spinal surgery (I'm interested in neuro, and I could see myself working in the neuro rehab unit) Well anyway back to the subject I always thought that the heart or brain surgery would be the most risky one but like I stated before I keep reading that some drugs are contraindicated in the recent spinal injury or invasive procedure for that matter since there is a high risk for bleeding,I know you can get the infection easily and the procedure is one of the most painful one... sorry for the stupid question but I'm seeking a clarification.Also
