Yes. This technique will be supplemented by IV sedation during the procedure. The only time that this would not work is if the surgeon is going to do a laparoscopically assisted vaginal hysterectomy. Hope that this helps.
Hyst Anesthesia. Epidural can be used for a non-laparoscopic hysterectomy. In combination with sedation, it can be a very good form of anesthesia and post-operative pain control. If laparoscopy is to be performed general anesthesia is necessary. The pressure of the gas on the diaphragm would give you the sensation, if awake, that you cannot breathe and panic would ensue. Fully asleep is needed for that.
Yes, with caution. It is an option, however both lavh and davinci surgeries require absolute non-movement for surgical precision. Moreover, you would be awake and able to hear everything going on in the surgical suite.
