Anesthesia

General anesthesia will be used. You will be asleep.

Description of Procedure

Oxygen is given through a mask. A mouth guard may also be placed in the mouth. This will protect the tongue and teeth from getting hurt. Next, electrodes will be placed on the head. They will be hooked up to a machine. It will send an electric current to the brain. This will cause a seizure. After the shock is given, some muscles will contract for a few seconds. Next, the body will twitch, which can last up to a minute.

You will be taken to a recovery room where your vital signs will be watched. You will wake up in 10-15 minutes. You may feel confused. This confusion can last minutes, hours, or sometimes longer.

How Long Will It Take?

About 30 minutes, including time to recover after the procedure

How Much Will It Hurt?

You will not feel any pain during the procedure. After ECT, you may have a headache, and muscle aches or soreness.

Post-procedure Care

At the Care Center

When you are fully awake, you will be given something to eat and drink. In most cases, you will be able to go home the day of the procedure.

At Home

You will need to schedule an appointment for another ECT treatment. In most cases, you will need to have 2-3 treatments per week, for many weeks. You will need to take medication, such as antidepressants, and continue with therapy to prevent a relapse.

You may also need maintenance ECT to further prevent a relapse. Your doctor will help determine the right plan for you. This will depend on how you are progressing.
