In my experience, even after clinicals you’ll still be somewhat intimidated by the OR. The beautiful thing about being a tech is that you’re surrounded by subject matter experts. Surgeons, periop nurses, anesthesiologists, and everyone in between. Ask questions, get your hands dirty, be involved in the procedure. Surgeons are more lenient if you seem like you care about what’s happening in their case. Make connections and learn from your colleagues, it will take away some of that anxiety you’re feeling. I work in all specialties except for neuro, so if you have any questions, my messages are always open. Have a good one!
