I'm scheduled to have surgery soon. Is there any way that I can find out in advance the names of every medication I'll be receiving? Who do I contact?

No way . Unfortunately, there is no way on predict which medications you will need, and even those that are common are given by different doctors. Anesthesia specifically is not uniform among anesthesiologists. Best to share your concerns with your surgeon before you get to the hospital. They should be able to ease your mind, and let you know more about the local process. Hope this helps!
