My girl friend is wanting to have hydro thermal ablation, but she has trouble with general anesthesia, what other anesthesia can she have.

It depends on where : The ablation is. Have your friend get her old records and have them reviewed by the anesthesia department where she plans to have her surgery.

Regional Anesthesia: This procedure can be done under sedation anesthesia, or by using a regional anesthesia technique (epidural or spinal). However, a discussion with, and review of, the previous anesthetic should provide a smoother general anesthetic should she choose to go that route.
