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.
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.
