Thank you very much I've learned that at stage 3 The pupil is constricted But at stage 2 and 4 The pupil is dilated and because of that we use corneal reflex to determine whether the patient is at stage 2 or stage 4 Stage 2: there is corneal reflex Stage 4: there is no corneal reflex Thank you again And great job
I like this video! In practice, we rarely comment on the stages of anaesthesia, as there is a very blurred distinction between 'planes' now because of the rapid onset of the agents we used. Also - the planes are confounded when we use neuromuscular blockers). I believe Guedel described the planes when he was using VERY slow onset agents (ether, volatiles etc) rather than Propofol for example, that exerts its effects in one arm-brain-circulation time on injection! I go into more detail on anaesthetic practice on my TH-cam channel if you're interested, but I think this is a GREAT introduction for medical and nursing students!
Jessica Johnson You'd start the process of resuscitation, the Anesthesiogist will usually hang/push meds(ex. Epinepherine,Atropine,etc.) You could defibrillate the heart, or you could start compressions, depending on the operation.
my father went bradycardic at one point during surgery, not a full arrest, but close to it, down to the teens. He got a shot of atropine and bounced right back to NSR.
@@doctorbobby4543 i only ask because i remember when i reviewed my own surgery at work, the anesthesia log said before i was transferred to PACU, my vitals whole surgery were stable but upon awakening i was at 112 bpm SVT then sinus tachy then i returned to NSR shortly after. Went home with uneventful and was never told anything about it.
Propofol without premed 1. Anxiety/ Burning vein 3. Feeling like there is not enough air/ dizzy 3 Relaxing/fall asleep 2. Voices telling me to wake up 1. Postoperative pain. Ketamine hallucinations. (everything looks like a huge, moving cubist painting) Whole body numbness for about 90 seconds then return of postoperative pain.9/10 Second ket bolus - as above but pain reduced to 8/10.
I do realize that waking up and going to stage 2, I was shaky and nauseated for a while (I puked 3 times). That was because while they were putting my cast on... I woke up and they had to quickly put me back to sleep temporarily. Then waking up finally. Does that affect your stability when going from stage 2 back to stage 3 then back in stage 2?
+Tifowman there is no stage 5. stage 4 is the highest you can go- if you wanted to iatrogenically stop the heart and medulla, then stage 4 would cover it

Thank you very much
I've learned that at stage 3

Stage 2: there is corneal reflex
Stage 4: there is no corneal reflex
Thank you again
And great job
It is the summer of 2020. I am currently in quarantine. I am going into 10th grade next year. It is 1:42 AM. *_How_* and *_why_* am I here?
I can't thank you enough.
we can't be happier that you enjoyed the video

yes this is a nice video, I made a video about valoration of anestesia you can check it on this link th-cam.com/video/sEmusHC-Kas/w-d-xo.html
I imagine TIVA was not exactly a thing
Guedel used diethyl ether..
Good and simple intro for dental students too
thank you so much for this. i was struggling to find a video that explained the stages and im so glad i found this. thank you so so much.
whay did you miss out Midazolam at the begining? surly as a premed or precursor to the propofol midazolam is given?
It's not necessary. I don't give it often to my patients.
Lay man may make wrong use of direct medical information
Be careful
Why do you take a video from Khan Academy xDDDD
Traverse: to move across. Transverse: a plane through an object. ;-)
Well if the heart does stop what would you do?
Jessica Johnson You'd start the process of resuscitation, the Anesthesiogist will usually hang/push meds(ex. Epinepherine,Atropine,etc.) You could defibrillate the heart, or you could start compressions, depending on the operation.

could you please post your references ?
During the hyper excitability state during stage 2 of emergence, is a sudden increase in heart rate also attributed?
Yes and return of airway reflexes as well. I am a physician Anesthesiologist and talk about this on my TH-cam channel.

If your doing a heart surgery would u go to stage 5??
+Tifowman there is no stage 5. stage 4 is the highest you can go- if you wanted to iatrogenically stop the heart and medulla, then stage 4 would cover it
Tifowma
No. You iatrogenically arrest the heart using potassium based drug agents.
