If you are having general anesthesia in the hospital, you will be told not to eat or drink anything for a certain period of time (usually after midnight the night before) before the procedure. Routine lab tests may be ordered as well for women having a hysteroscopy in the hospital. You will be asked to empty your bladder and your vaginal area will be cleansed with an antiseptic. Sometimes a drug to help you relax is ordered. Next you will be prepared for anesthesia:
Local anesthesia:
You will receive an injection of anesthetic around the cervix to numb it, with this type of anesthesia you remain awake and may feel some cramping.
Regional anesthesia:
A drug is injected, through a needle or tube in your lower back, that blocks the nerves that receive sensation from the pelvic region. You are awake with this type of anesthetic, but feel no discomfort. Regional anesthesia is also called a spinal or epidural.
General anesthesia:
You will not be conscious during your hysteroscopy when general anesthesia is used. A mask over your mouth and nose allows you to breathe a mixture of gases. Once you are under anesthesia, a tube may be inserted down your throat to help you breathe. Your physician will determine which type of anesthesia is best for you based on the reason for your hysteroscopy. Remember to ask questions if anything is about your procedure or anesthesia is unclear.
