Oh yeah electroshock therapy is actually something we still do. I've worked at two places actually who do it. They put the patient under full medical sedation like they would for surgery (they even have a little mini recovery and PACU in the ECT suite). In fact the only main difference between an ECT suite and an OR suite is that the actual procedure room is just clean, not fully sterile since they're not actually opening the person. On the floor we have to observe all the same pre-op and post-op precautions, like NPO (nothing to eat or drink) after midnight, and changing them into clean clothes in the morning. We don't have to do a chlorhexidine scrub (again not sterile) but showers are encouraged (sometimes the patient is too sick to tolerate even a bed bath though). Our only special precaution is that we have to stop all anti seizure meds the night before because the whole point is to induce a seizure.

They just put electrodes on kinda like they would with an external defibrillator to stop an abnormal heart rhythm (except obvs they put them on the head, not the chest). Then induce a controlled seizure that lasts like 60 seconds or so, then use medications to stop the seizure if necessary. In fact it's almost exactly like a heart defibrillator in that we're turning their brain off and on again to get it to work! Funny that that works with organs like it does with computers! 😅
