Glad you found the series useful. We'll put Hypernatremia on the slate for a future lecture. We are doing a vote on our MedCram Facebook page for the next topic to be covered. Take a look if you get a chance.
Glad to clear things up completely. Thanks for the feedback.
See the whole series at www.medcram.com along with other top quality videos including reviews in pulmonary, cardiology, infectious disease, and hematology!
What kind of doctor would be able to diagnose disturbances in my osmilality?? Endocrinologist???
What dietary advice would you give to achieve peak osmilality???
Hyponatremia and fluids are one of the hardest concepts to grasp--at least in my view--and thankfully you have clearly explained this concept in a way I visualize it and understand it! Thank you SO much! I'm a pharmacy student on a critical care rotation in a burn unit and was told to look up how to to workup/assess and treat hyponatremia and after watching & taking notes on these videos I feel absolutely confident to explain this concept!
OMG I LOVE YOU DR.SEHEULT! thank you so much for this clear explanation!!!!
Wow, It's amazing to learn from teachers who teach with passion. Thanks. "if you can't explain it simply you don't understand it well enough", you've made ir pretty simple.
+Daniela Jaramillo Ramírez Good to hear- thanks
Daniela Jaramillo Ramírez
That's the best series of lectures I've ever seen! That's awsome
I really appreciate the way you teach. You made my work way easier. Thank You
I've read so many books and attended so many talks but never like this. Many thanks Roger,you have no idea how many people you have had helped. I'm still waiting for hypernatremia.
Thank you. Your explanations make it all of it clear and easy to remember.
Thanks so much; you do an excellent job on these. I'd love to see you handle all the electrolyte disorders commonly found on Step 2, etc. as well as renal tubular acidoses. Great work!
It's really good to finally understand the basic things here. Thanks
Thank you so much! I told some friends about Med Cram and appreciate your help. I would love to see more topics in the future.
I also appreciated your videos on Hypoxemia/Hypoxia.
You should work for Kaplan or come out with your own series covering all subjects from Pharm to Path to Microbiology and so on.
High level of patience required to watch this video MAN!!!!
+Merlin Samuelkutty your doing a great job! Keep with it and knowledge will be yours!
Thank you for catching this mistake. An annotation at 2:37 has been added to correct it.
Thanks Dr. Seheult. I'm looking for the series of other videos
Very clear video, great job! Thanks for creating these series!
One thing I'd like to bring to your attention: from your video it might be incorrectly assumed that intracellular and extracellular sodium concentrations are equal, which they are not (12 mmol/L vs 140 mmol/L respectively).
Thank you so much, very helpful
Helpful for RN students. Thanks!
You are really world class!
Great lecture!! Thank you!!!
Thanks a lot for your time and help!!!!
'hypo' meaning low, 'nat' meaning sodium, 'emia' meaning presence in blood... low sodium presence in blood...😉😉
seriously though, huge thanks for this series🙏
Great explanations super clear thank you!
Absolutely brilliant! Thanks so much Doc :)
Many Thanks for video lecture. I would really appreciate if you could kindly post the video related with NIV, BiPAP, CPAP and the mechanism involved in these modalities.
Amazing series. Very helpful video series.
The foundation or basics count in any construction or knowledge building . Great explanation !
For all the med students here: know that consumption of mdma can lead to Hyponatremia. So if you have a patient coming from a nightclub, don‘t forget that it could be Hyponatremia and you may save a life.
I can't believe there are people who don't like this video. Thank You. This is awesome!
thank you for your help
Amazing explanation ❤
Brilliant!! loved it.
Great video, thank you so much!!!
thanks alot for this incredible teaching videos,,,its the best
again thanks
Thank you for this
Thank you!
Wow! Thank you so much!! You are amazing!
thanks so much
Great video. One error though, at baseline [Na] is not equivalent in ICF and ECF. Na is mostly an ECF ion.
I'm probably one of the most stingy person to give "Like". This definitely deserves one. Great lecture.
thank you! do you have any pharmacology related lectures?
Totally what I expect from a doctor! xxx
BUN: Blood Urea Nitrogen. It is a measure of the amount of nitrogen in the blood in the form of urea, and a measurement of renal function
that is amazing thank you so much but I cannot find the rest of videos related to hyponatremia .. can anyone send me the videos or links please
Unbelievable that after two years of nursing school, I don't think I ever COMPLETELY understood WHY 0.9% NS was what you used. Thanks so much!
Thanks! Could you make more use of different colors in the next videos? It helps with getting the message across more clearly.
Excellent
hi i was just wondering if you have any links to the references that you have used? i would like to use this for my assignment but i need to include review papers too!
(hopefully you see this in time)
I am living with this nightmare. I have been in and out of rhe hospital constantly thie last few years. I'm tired of it! Came close to dying a few times.
At least now, I know what's going on with me now. Hopefully I can my potassium and sodium right so I can finally feel good again, I and stay healthy. 😊
This was the most terrifying experience of my life!
The Unit . It’s not 135 mg/dL .its 135 mEq/L
When you add normal saline at 15:16, the read line is supposed to stay at the vertical level of the purple line right? Because the Na+ concentration doesn't change, right?
thank u so much sir...!!!
Thanks for your efforts Sir! Seems this was for medical students..Please summarize in lay man language symptoms n treatment so that normal people also have some knowledge
Your video is amazing!! If possible don't write over on your note, they are already very clear.
Why only the first video is there ? The 3 other videos of the series are hidden 🥲
Brilliant explanation! I just have a question, isn’t the Na conc in ICF different to ECF anyway? The concept would apply to osmolarity though since it’s the same intracellular and extra cellular
Thank you
thanks dr for the amazing series! i have a presentation on hyponatremia and ur lectures are the best reference!
i hv a suggestion: could u plz do lectures on antiarrythmics and explain the physiology underlying them.. this is a vry tough topic fr me and i would appreciate that so much.. thx :)
wow! u are awsome, you realy helped me. thank u so much.
+nastaran p Good to hear- thank you for the comment
Saw all four videos for topic, I have a better understanding. Awesome job!!!
Huge request, Dr. Seheult: could you please do lectures on basics of pharmacology?
Thank you for all your great videos!
+Irina Kim Thanks for the good suggestion on a pharm series!
Sir you should upload again the video which had 4 or 5 parts it was so explanatory
would you say y axis is na concentration instead of na? so the area is (na/h20)xh20 which make more sense? good video btw, thnk u!
Not mg it is meq/L is t he Na concentration
Abdelwahab Naas i was looking for this comment
Please correct the units of sodium in 135 mg/dL to 135 mmol/L or meq/L from 1:35 onwards. That is the unit that the Clinical Chemistry laboratory provides you with.
at 2:44 units of osmolality is mosm/kg and not what is stated!
why ecf Na conc remain same on adding i/v N/S?
can anybody tell me what software is that!!!! (drawing one)
Why the other videos are private?
Does this has a part two? Is there is a video on management?
You can find more of our videos at MedCram.com. This is part of a three-part series on Hyponatremia.
Ringer lactate is best to expand ecf
Coming soon.
this might have been mentioned before, but you said 0.9% saline, but .09% was written at 14:30.
Also thanks many times for this lecture series - easily one of the best on youtube!
What to give in hypervolemic hyponatremia causing cerebral edema?
thank you :D
i searched videos for hypernatremia but i didnt find,,,can you help me please?
is dat if medicine for hypothyroid is stopped for few days may cause hyponatremia
what is the reason of hyponatremia in pneumonia? what is the relation of pneumonia with hyponatremia?
Majid Khan incompletely understood, but the syndrome of inappropriate antidiuretic hormone secretion is felt to play a significant role possibly secondary to inflammatory mediators (cytokines etc)
Muchisimas gracias
I went to the doctor and when I got there, I got out of my car and my legs got so weak I was shaking and could barely walk. I had to have help into the doctors office. I had a headache that wouldn't go away. They did blood work and my sodium was very low. I was told to go home and eat alot of salt. Nothing is working. I'm losing my balance and scared I'm going to fall. My legs and feet cramp like crazy. When my legs get weak, I go down and it's like I have no control of my legs at all. I'm scared and don't know what to do
You should seek medical attention immediately.
Same here!! When I got to the emergency room I couldn't turn my head without feeling I would fall down ! Our normal sodium count is 135, i was at 113, as soon as they saw that I was rushed back to a room and admitted, three days latter and I went home with the knowledge that I have hyponatremia , what made my situation worse is my doctor did not do any blood work 3 years ago , he just thought, hey another h.b.p. case! So he gave me lisinoprl with a hydro stripper,( removes sodium by increasing water loss) this just made it worse for my situation, now he's afraid I'll sue, i almost died because of that, i was told that my body was going into protection mode, if I had waited much longer to go in I wouldn't have made it!! Please check your sodium level if you haven't already ! Hope your back to normal!
Sorry, now I see did do blood work! I dont know what they could be thinking ! It's very dangerous to increase sodium to fast, or, too much! They are unfit to care for people!
I believe my 6 year old is suffering from Hypernatremia. She has seizures often and we can't figure out why. What test should I ask for? Please help!! We are in IL and have great insurance, we are open to try new doctors.
What does it do to u how it happen
Hi doc, is it bad drinking 500ml to 800ml every 2 - 3 hour? I HAVE uti and GERD so lately I've been consuming a lot of water (I think) Please reply. Thank youu
We can measured osmolality using instrument..such as Advance Osmometer 3320...Will that be different??
Jon Goh could be if osmolar gap typically very similar numbers between measured serum osmolality and calculated osmolality. Other minor contributors to osmolality not typically factored in due to negligible contribution to osmolality
All these videos explaining hyponatremia and SIADH for trainee medicos and other health professionals.
Great. But what about the patient??? How does the patient find out what to do on a new diagnosis??? When I exercise in a warm climate do I just not drink. and become dehydrated. Or do I drink and take a salt tablet?
Do I just give up on a healthy exercise regime???
Where's the information for the layperson and patient???
from stewart approach of acid base, i think normal saline isnt the best balanced solution for resuscitation
eldwin suputro good
No, it is not. Ringer lactato (Hartman solution) is the best choice.
I’ve had hyponatremia every summer since 2016, due to my epilepsy rx. My symptoms cause: confusion, restlessness, loss of appetite, lightheadedness, pressure on head, and fatigue. Last August was the worst. I waited too long and it felt like I had a bunch of weight on my head, I could barely speak, and my legs felt really heavy. I wish I didn’t have to continue to get this because it’s not fun. There’s only so much salt I can eat.
No, because you are only measuring the nitrogen attached to the urea (and not the exogenous nitrogen).
this happened to me a few days ago.. it was absolutely hands down the worst experience in my life. i thought i might die or else i would end up permanently brain damaged. i think i was VERY close to having a full on seizure and becoming unresponsive.. luckily i got an iv with sodium drip and it managed to fix it (albeit after many more hours of pain). they were giving me valium and morphine and it barely touched the pain i was feeling. i couldn't hold still. my limbs were just jerking all over the place. even the valium didn't really stop it.. just slowed my twitching down a little
swish007 How quickly did symptoms set on?
well i was feeling nauseous the day before but ok.. apparently it had been a slow buildup over a week or so where i was drinking lots of liquids (including diuretics) and taking a water-retention pill or whatever. so then basically i woke up that day feeling really weird and bad but not quite sure if it was something that warranted a trip to the doctor. but i started looking up my symptoms online and saw that it could be really serious so i got a bit freaked out which made me feel worse. then i told my mom i think i needed to go to the hospital (at this point i was having trouble talking and my breathing was off) and she was like well lets go to the urgent care (after trying to call my family dr and the pharmacist.. no help from either).
so we went to urgent care and they looked at me and said i needed to go to the hospital. at this point i was in a LOT of discomfort.. and i want to say it was early afternoon. then when i got to the ER i had to wait like almost 2 hours in the waiting room and i kept getting worse and worse. it got so bad i couldn't sit still.. i had to get up and pace but i was so exhausted i felt bad when i walked around. then it just devolved into me rocking myself in a chair while the ER workers ignored me. after the fact i realized they may very well have thought i was withdrawing from some heavy-duty opiates or something because it seems like the symptoms would be similar.
anyways i want to say maybe 4 or 5pm i finally saw the nurse who checked my blood and pretty soon after started me on a sodium iv. when the sodium started going into my system the pain got WAY worse for some reason. but at least the nurse bothered to tell me that no, i wasn't dying and i'd be alright. i just had super-low sodium levels. so that made me feel better mentally.. but i was still in the worst pain and discomfort that i think i've ever experienced and it didn't seem like it would ever end. every minute felt like an hour. i was too weak to stand up but i couldn't handle laying in the bed so i would alternate between laying in the fetal position and sitting up with my elbows on my knees and my head down. then finally they gave me some pain killers but it only gave me a little relief and then i started feeling really bad again. (this was after i saw the ER dr who basically just told me what i knew and said he would get me some pain killers).
then a bit later a more awesome nurse came in and gave me some much stronger pain killers and some valium. which did help me feel better.. but then a couple hours later i was feeling bad again. not nearly as bad as before but still like i wanted to crawl out of my own skin. then they wanted me to stay overnight and they put me in an overnight room and gave me more morphine and i FINALLY felt better for a short while.. and there was such a release of tension that i got really emotional.. because i had been like straining all day it felt like. so then the discomfort came back and i asked for more pain killers but the nurses refused and even gave me that attitude like i was a drug addict for asking which i didn't care for. and so then i decided to have my sis drive me back home because no way was i staying. and at that point i had regained all my motor functions and my brain felt normal so i was sure i'd be fine. and sure enough i went home, had the best sleep of my life and woke up not only feeling better, but a LOT better than normal. i guess the iv just did its job super well or something lol. but yeah it was crazy
Oh ok, reason I asked is cause I was using a tredmill with a friend, I had about maybe 2 bottles of water, or maybe just a bottle and a half, during the 20 min workout, and he told me about this whole overhydrating thing after and I've been in anxiety mode since....its been roughly about 50 min since the workout and I feel pretty fine. I feel like id have to drink like 4 bottles and run a marathon to get a life theatening case of it though, or am I just telling myself that...
yeah you would know if you were starting to feel like you had it lol. i mean the early feeling was like i was coming down with a weird flu. and like i said i felt it probably more than a day before the sh%t hit the fan
swish007 i mean i drank. a couple bottles speed walking on a tredmil, pretty sure athletic causes are more like chugging a litre or so while running a marathon
Any translation for laypeople?
Why were the rest of the videos made private?

MedCram - Medical Lectures Explained CLEARLY ah thank you!
Me, as a person with no medical knowledge, who takes diuretics and also does ultramarathons in 45 degree (Celsius) weather: 😅
I drank 1.25 litres of water in the space of 30 seconds and woke up a few hours later and started vomiting. I have the worst stomach pain I’ve ever experienced, and can’t sleep. Do I have this condition and will I die 😥😓. I am actually so worried someone pls tell me if that amount of water is enough to kill me
+Nudist Priest 1.25 liters is not a dangerous amount of water. Look for something else with consultation with a physician.
Na 135 mEq/L is equal to 135 mg/dL , is it ?
+para math yes.
+MEDCRAMvideos my mistake should be the latter
It´s not the same 135 mEq/l and 135 mg/dl. Because 1 mEq/L = 2.3 mg/dl
Thank you for the comment, Yes, I meant to say 135 mmol/L (not mg/L)...We have an annotation on the video (but apparently annotations are not visible on mobile devices).
Could someone drinking too much beer cause it?
Glenda Williams Yes.
Hypovoleamic
I drank 2 16.9 oz of water within 1 hour and by the time i have posted it has been about 13 hours. I am 15 and I'm afraid I might die, I haven't told my parents because my mom has warned me before. I was not doing any exercise within that time and I want to know what the possibility of me dying rn is. Please help
Pinkinizer Pug I just drank 2 bottles of water in a minute I'm carping my pants
+Pinkinizer Pug it's pretty low! You'll be fine.
