does anyone have any idea what this means? I am scared to death and I'm in seems to be able to tell me what exactly this procedure entails. My procedure was switched at the last minute from a regular laminectomy to this. It's supposed to be done in the next 24 hours, and I didn't find out about it until 6 PM this afternoon from the hospital they could not answer my questions. My doctors office is extremely busy and I can't get any answers. I don't even know if this is outpatient observation or inpatient. Please if anyone has any answers I really need some thank you.
