Retired RN here. I was working ICU once back in the early 90's and the cardiologist came in along with the anesthesiologist. The patient needed a cardioversion. The cardiologist told a story of a big dude, years ago, who he was performing the same procedure on using only Valium. After about the 3rd shock the guy rose up in the bed and said if you do that one more time I am going to whip someone's ass. Times have changed.

I've had 4 cardioversions 2 were propofol/ketamine (the first time was a really interesting experience .. the second I had a really bad reemergence episode). The other 2 were propofol/fentanyl .. no problems at all there, it's a pretty good combination for cardioversions I'd say.

After having had far too many surgeries, I can say the anesthesiologist is the most important person working with the surgeon. If he does a good job you have a successful experience. Everyone is afraid of being that one person who is paralyzed but experiencing the whole surgery and can’t tell anyone. Only once did I wake up and see them working on my foot.

I found this video super interesting especially given the fact that I had surgery last week (local anesthesia with sedation). I got a copy of my anesthesia report and many of the same medications you mentioned were used (Midazolam, Fentanyl, Propofol, Lidocaine, and Zofran). I was so glad that I didn’t feel sick from the anesthesia as I did after a previous surgery. Little did I know that it’s probably because of the Zofran. Love these videos. They are very interesting!

You always explain things so clearly that it really helps those of us not in the medical profession but having procedures and curious about this component. Why do some patients have such a hard time coming out from anesthesia?

[@MaxFeinsteinMD]

I appreciate that! What you're describing is a phenomenon called delayed emergence, which can be due to factors related to medications that interfere with cognitive function, or occasionally (and unfortunately) neurologic deficits that develop during surgery. There are many other reasons but these are the ones that come to mind first.

I recently had a colonoscopy screen and was given propofol by an anesthesiologist. I was impressed how quickly I recovered from the propofol. A few minutes after awakening, I was able to dress and walk on my own without grogginess. Amazing medication. In the past I was given something else and was sedated for the rest of the day. This is a huge advance in this field I think.

[@charisma-hornum-fries]

I wasn't that out of it when I had mine. I was completely conscious and aware. So much that I watched it all on a screen in front of. The doctor did a sightseeing tour in a very entertaining/ funny way. I couldn't feel a thing but remember a surreal yet positive experience.

This is so interesting as a layman. I just had spinal surgery and my anaesthesiologist was amazing. He made me laugh, he calmed me down, he answered all my questions and I had zero anxiety before he put me to sleep.

Would be cool to see a video on anesthetic emergencies and how to treat them , like malignant hyperthermia and dantrolene as an example

[@MaxFeinsteinMD]

Thanks for the idea, I will consider this for a future video!

[@MaxFeinsteinMD]

Thyroid storm from hyperthyroidism can be an emergency, but it's a different one from a patient who has malignant hyperthermia (also can be an emergency).

[@AJohnson0325]

The main thing is to remove the offending agent (succinylcholine or volatile anesthetics), turn up your gas flows above minute ventilation, 100% oxygen, increase minute ventilation, and get the danteoline in. 2.5 per kilo initially. It has to be mixed with a pretty large amount of sterile water 60 ml and you’ll need multiple vials so you’ll need people dedicated just to mixing it. I’d put in an a-line and get an ABG with electrolytes because the patient is probably hyperkalemic and you’ll have to treat that too. CaCl, insulin, d50, etc. One of the first things you should do is GET HELP and if you’re in an outpatient center call 911 early. pack the groin and axilla with ice. That pretty much covers most of the things that would kill the pt. I believe some protocols also call for placing charcoal filters but if you have removed the vaporizer and increased fresh gas flow above minute ventilation then the chances of rebreathing a significant amount of vapor is pretty low

Many years ago I had a breast biopsy and the anesthesiologist talked me into a mask/gas induction. It was the single most terrifying event of my life. I proceeded to avoid any type of sedation for years. I was 15 years past recommended colonoscopy range before I gave in to my husband's insistence. Propofol was not terrible but still disconcerting I knew when I was going out as opposed to just going out. However as opposed to gas, where I went out in panic attack and woke up in panic attack, I faded out and woke up.

Hey Doc, My All time favorite educator/ speaker was a friend by the name of Scotty Bolleter (at the time with San Antonio Airlife)...

I worked as a Paramedic both ground based and air based on fixed and rotor wing aircraft. While it has been years since I’ve pushed any meds, your down to earth delivery and fore-sight explanations hit home and I’m enjoying the videos you make... I just had a procedure done and was giving the anesthesia Doc a hard time... The new (to me) nasal cannula with the tab that covered my upper lip and hung into my mouth, was hooked to a monitor for respiration’s and I asked if an old fashioned mirror (fogging with expirations) was too much to ask for... lol ... I didn’t care for the tab... until she started the Propofol... Then I didn’t care about anything... What strikes me is compared to even only 40 years ago (my original knee surgery), I can/did have a knee replacement outpatient or at the most one overnight stay... (I have an extensive cardiac hx) with little pain, (even at home) no grogginess, no anxiety, no nausea....

Yo Max, you’re videos are very interesting! They make me glad I didn’t choose to be an anesthesiologist. That said, I've had the dubious privilege of having been under GA for at least 15 times, many for eye surgery, but also 2 major orthopedic operations. Both involved the insertion of screws and other related hardware into my left ankle (fracture) and right foot (osteoarthritis). The ankle procedure people used some sort of gas that left me feeling like I'd been breathing through an exhaust pipe. The foot surgery was more recent, and instead they used a nerve block and milk of amnesia (aka propofol). I agreed to it with the assurance that I be completely oblivious to the whole ordeal. It worked, thankfully. Is there a trend toward using propofol and nerve blocks in anesthesia these days? Another thing that seems to have been phased out is the use of a preop medication like demerol, etc. They haven’t used it for me in a long time. I found it preferable as it relieved anxiety, plus made for a pleasant buzz. I’m hoping my days of surgery are behind me, but who knows?

What do u use If pt is allergic to fetanyl? I love the profanol I get with spinal blocks. Quick to be out quick to wake up. I love your videos. Makes us not fear surgery so much! Thank u

[@MaxFeinsteinMD]

Hi Sherry! Fentanyl allergies are extremely rare, I suspect most anesthesiologists won't encounter that in their career. Other medications that effectively relieve pain during surgery include morphine and hydromorphone, so I would probably use those in a patient with a fentanyl allergy.

[@sherrydawson6253]

@@MaxFeinsteinMD I had a anesthesiologist not believe that I was allergic to it gave it anyway I immediately went into anaphylaxis. Thankfully it was a nurse that noticed huge welts at same time anesthesiologist notice 02 dropping fast . He was in the recovery rm with me. I was still entubated . If it weren't for the concern he showed and the fact he stayed with me I would of swarn at him..after that a allergist did a scratch test and blood work but before labs had a chance I was wheezing had a hive that covered half the back. He told paramedics something about like only given a small amt that was diluted to prevent a bad reaction So I warn surgeons test me as some anesthesiologists don't listen. So far they listen. I like u cover pre op anxiety pain and nausea. So many my husband and I have encountered did not.if I got 1 like u I'd be so blessed. 💜💜💜💜AMEN TO U!!

@@sherrydawson6253 I'm allergic to some plastics or tape, and rubber. Doctors don't believe. It's hard. I'm fine with staples to close surgical incision but not plastic sutures.

This video was fascinating! Thank you for giving us an overview of what goes into your job. Without anesthesia, surgery wouldn’t be possible!

I love watching your videos! I'm having my 5th brain surgery next month and it's my 42nd overall surgery and these are very informative. But I want to know what medication makes my ears ring really loud right before I'm asleep

[@TemplarsWildFire]

will be praying for you. I might be having my first brain surgery soon. It's freaking me out!

[@curtiswritt8474]

I have water on the brain (Hydrocephalus) so sadly I'm used to these surgeries but I'm not liking when everything stops working. I really hope your situation goes well!

[@MaxFeinsteinMD]

Most likely it's a local anesthetic called lidocaine (the vial with the green top that I mention in this video). Best wishes for your surgery.

[@lootleo4022]

Gosh I wish I had the sense enough to pay attention in school because this is amazing and helping people to get through surgery is fascinating!

[@tylerfoley614]

Just wondering why do you tape a patients eyes closed after you intubate them? What would you do if the person is getting a vitrectomy?

[@fireguymel]

The eyes are taped shut to help keep them mount and avoid any possible potential for getting something in them.

[@mariuspata664]

Because the patient can't blink when he's under general anesthesia. And blinking helps the eyes keep hydrated and lubricated. If the patient's eyes are open for several hours without blinking, there's a risk of developing keratitis (or corneal ulcers). During vitrectomy or any ophthalmic surgeries, the eyes are constantly lubricated with various drops

Why did you choose Fentanyl over Sufentanil?

[@mdye8748]

M3 here interested in anesthesiology, thank you for explaining this so well before I start rotating!

[@Unuthryear]

Ok while I understand no 2 inductions are same. I have had 2 surgeries that have had same Anesthesiologist and General surgeon. 1st time I was induced the Anesthesiologist gave me the paralytic meds before induction, that 30 to 60 seconds was horrible couldn't move and was well aware of that. The 2nd surgery I asked Anesthesiologist if they could make sure I was sedated before he paralyzed me, because it was scary feeling. You would of thought I was questioning credentials. Could you explain why this was his thinking

[@MaxFeinsteinMD]

Eek, that sounds disconcerting. I can't explain why your experience would have unfolded like that.

[@jessicazeller8060]

This info is so helpful for me in knowing what to ask my doctor and anesthesiologist for my upcoming surgery. Thank you!

My wife does Cat Scan at a large teaching hospital and the techs and nurses say if Docs even residents walk in with their names embroidered and Tailored scrubs they almost always arent very good with paitients or staff. They call them “ show ponies” If they come in wearing regular everyday scrubs they will be the exact opposite. I think she’s right. Love this guy.

[@MaxFeinsteinMD]

Lol that's hilarious, I love the concept of show ponies.

Thanks again for this great Video🤝🔥🔥🔥

[@raybeavers3123]

Great detailed video and so knowledgeable about every drug given from surgery START until SURGERY IS FINISHED. Thank You Dr Feinstein, for sharing this valuable information to us. I am scheduled for a Total Right Reverse Shoulder Replacement soon and was thinking about the sequence of meds given to put patients to sleep. Unfortunately, I had to have 4 Rotator Cuff Surgeries in 2023, due to my Blood Thinner meds, that were causing my Rotator Cuffs to Deteriorate as well as my tendons and ligaments. FYI Take Good Care and Stay Safe my Friend! Great Job! 👏👍🤗🇺🇸🫡🙏🙏

[@bentaylor2519]

great content, thanks for the great videos! I have always been curious about pain and how humans manage. For example, watching game of thrones or documentaries about regimes in other countries and seeing all the torture and physical pain they seem to survive through, I just wonder if that is possible or do humans begin to suffer irreversible damage (psychological, brain or physiological) at a certain level of pain? or does the body go back to normal once the pain stops? do you use the same class of meds that a pain management doctor would use? seems like anesthesia is more about preventing pain, and pain management is about managing chronic pain, but they seem similar. I saw a netflix show recently about a serial killer in asia back in the 70s. he seemed to use a paralytic drug, given orally (like a pill) and the person would be awake, conscious, but paralyzed. he would rob them and throw them in the ocean in that state. I have to imagine that would be horrible. I also hear horrible stories about people waking up during surgery, but I am not sure if that is true. or the anesthetic never fully takes and the patient goes out, but stays conscious somehow? I dunno, maybe those are just urban myths, but that also sounds frightening, but then i hear that in brain surgery, the patient has to be awake, so how is that possible, lol....sorry for the rambling comments!

[@davidadams9391]

👍👍👍 Another GREAT video from Max’s school of Anesthesia!! This is good information for patients! How long do you stay with the patient after the surgery is over? Thanks Max

[@MaxFeinsteinMD]

The short answer is that it depends on how stable the patient is. If vital signs aren't stable, I stay with the patient in PACU until either they are stable, or I've done a thorough workup and signout with the anesthesiologists running PACU. I'd say 99% of my patients are stable and I'll leave within 5-10 minutes of getting to PACU so I can prepare for the next case.
