The gasserian ganglion block is a safe medical procedure, but as with any procedure it has risks, as well as benefits. To minimize the chance of complications, we ask that you follow a few simple guidelines:
Do not eat or drink anything for six hours prior to the procedure. An exception is always made for routine scheduled medication, which you can take with a sip of water.
We ask that you be accompanied to and from the Ambulatory Surgery Center by a responsible adult driver. Pain Management physicians, or a nurse in the Ambulatory Surgical Center may offer a small dose of relaxing medication prior to the procedure, which could impair your driving ability.
Plan on spending approximately ninety minutes in the Ambulatory Surgical Center. This includes time for registration, preparation, performance of the procedure and observation period.
