AH, Cecil. Finally a topic I have more than a modicum of information about.
As a healthcare provider (ghastly euphemism) I’ve assisted in administering Electro-Convulsive Therapy (ECT) to at least 60 patients in the past ten years. Probably 600 episodes. I do have an opinion about this technique and that is that when it works it works great and when it fails, well, life sucks.
I’ve seen patients curled in the fetal position, unable to relate to anything or anyone, blossom into persons again. I’ve also seen tragic failures where probably no therapy would have resulted in a happier outcome.
In all cases, I have never seen any deleterious effects from the therapy itself. Transient confusion (resolving in a couple hours) and loss of memory of the event (the ECT and a few minutes before) were the most common side effects. Anesthesia always controlled the flow of events and assured the safety of the patient. A quick acting barbiturate was given via an I.V. and when the patient was asleep a rapid onset, short action neuro-muscular paralyzing agent administered, usually succinylcholine. The patient is now asleep, essentially paralyzed, and completely monitored. The anesthesiologist assure adequate respirations via a resuscitation bag and 100% oxygen.
The ECT itself is unspectacular. A previously inflated blood pressure cuff on the ankle kept the paralyzing drug out of the foot so we can monitor the the peripheral seizure by watching the toes twitch. An electroencephalogram (EEG) allows us to monitor the central seizure by watching the brain wave patterns. The usual seizure lasts approx. one minute. If the seizure continues for longer that anticipated, drugs can be given that stop the impulses. A common goal is to give between 500 to 1000 seconds of treatment over time. The patient MUST be closely monitored for clinical effect; no improvement is often not a reason to terminate treatment early on in therapy.
Wordy, but I hope this dispels some rumors and misconceptions. ECT is not a panacea nor an evil, just a tool.
