    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 RUclips channel if you're interested, but I think this is a GREAT introduction for medical and nursing students!

    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.

      ​@josephreses3774 I so agree midazolam is totally unnecessary. I had the misfortune of getting it in pre-op, I think. I don't even remember that. I remember absolutely nothing after pre-op. Barely remember the recovery either. It's all too weird for me to have this kind of amnesia and I don't like it one bit. I keep thinking I may have been violated in the OR. That bugs me to this day. ☹️☹️🙁🙁😣😣😣

    Well if the heart does stop what would you do?

    • @danielgremillion543
      @danielgremillion543 7 лет назад +1

      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.

    During the hyper excitability state during stage 2 of emergence, is a sudden increase in heart rate also attributed?

    • @doctorbobby4543
      @doctorbobby4543 4 года назад +1

      Yes and return of airway reflexes as well. I am a physician Anesthesiologist and talk about this on my RUclips channel.

      @@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.

  • @EMan-ml8er
    @EMan-ml8er 9 лет назад

    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?

    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.

    If your doing a heart surgery would u go to stage 5??

    • @MedSchoolMadeEasy
      @MedSchoolMadeEasy  9 лет назад

      +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

      No. You iatrogenically arrest the heart using potassium based drug agents.
