Terminology
Mechanism
- The brain is still not well understood, nor is the reason for the treatment effects ECT (shock) therapy has on some individuals. It is known that ECT affects hormones, neuropeptides, neurotrophic factors, and neurotransmitters in the brain. All of this may come together to explain how ECT works in treatment.
Preparation
- A full physical is generally needed before shock therapy. Because general anesthesia will be administered, one should not eat or drink 8-12 hours before the shock treatment. This helps to prevent any vomiting during the procedure. Other exams like an electrocardiogram (ECG) may also be given before ECT to ensure the procedure is safe and appropriate.
Treatment
- Shock therapy is performed in a hospital, sometimes in an area specifically set aside for this treatment. An intravenous (IV) is inserted to provide anesthetic medication. Vital signs are taken initially and continuously throughout the shock therapy treatment. An anesthesiologist administers anesthesia and after you are asleep, places a tube in you...
