The doctor sees the condition of your uterus and can make a more accurate diagnosis. There are some risks when you have general anesthesia. Discuss these risk with your doctor. A local anesthetic may not numb the area quite enough and you may feel some minor discomfort. Also, in rare cases, you may have an allergic reaction to the drug used in this type of anesthesia.
Local anesthesia is considered safer than general anesthesia.
IV sedation may cause you to have an allergic reaction to the sedative, respiratory arrest, lowered blood pressure, heart rhythm disturbance, or a bad reaction when the sedative is combined with other medications. These risks depend on the type, amount, and rate of sedation. There is a risk of infection and bleeding. The procedure may not correct abnormal bleeding. You should ask your doctor how these risks apply to you.
