It can be semi-open or semi-closed. But in old textbooks, they have mentioned it under semi-closed circuits. Semi-open circuits allow gas exchange with the atmosphere, letting in fresh gas flow, and have minimal or some recirculation of expired gas (Mapleson A and D). Semi-closed circuits recirculate some expired gas, but may still have a high fresh gas flow, and often feature coaxial designs (Mapleson C, F, E, and coaxial versions of Mapleson A and D). So, the configuration decides whether it's a semi-open or semi-closed circuit.

Talagang, ang isang laryngoscope ay nagbibigay ng mahalagang impormasyon tungkol sa mga kondisyon ng lalamunan. Kung nakakaranas ka ng matagal na kakulangan sa ginhawa, inirerekomenda kong humingi ng pagsusuri at paggamot mula sa isang propesyonal sa pangangalagang pangkalusugan.
MIGHT cause amnesia. It has never prevented me from making new memories of painful or disturbing procedures. It does cause some amnesia in the way of not being able to remember the sequence of events for the time elapsed. My pet peeve is so much is made of it amnesiac effects as if that is an amazing effect of this drug. let me play. Devils advocate for a moment and take it to the extreme, suppose one found themselves in a situation where they were being tortured. But the torture for some reason were empathetic enough to give you sufficient midazolam to ensure amnesia. Would you be comfortable undergoing torture for however, long it lasted as long as you knew that you wouldn’t remember it at least consciously? I believe there is some knowledge that the brain retains all memories on some level even if they cannot be tapped into at that time.
Your take on amnesia is thought-provoking! It's like a double-edged sword - it might offer temporary relief, but it doesn't erase the underlying trauma. Perhaps it's time to shift the spotlight from forgetting to preventing such distressing experiences altogether.
Thiopentone is usually administer only through Intravenous route due to its rapid onset of action. Oral administration is not commonly used for anesthesia because it has poor bioavailability and unpredictable absorption. Additionally, the required dose would likely be impractical and potentially unsafe to administer orally. As such, there isn't a standard dosage established for oral administration. However, if you're conducting research, you would need to consult specialized medical literature or conduct studies to determine appropriate dosages, considering factors such as absorption rates, metabolism, and safety profiles. In general thiopentone intravenous induction doses range from 3 to 5 milligrams per kilogram of body weight. This dosage of thiopentone for anesthesia varies depending on factors such as the patient's weight, medical condition, and the type of procedure.
Yes, both the jaw thrust and head tilt-chin lift maneuvers are beneficial when a patient is lying in a lateral or side-lying position. They help open the airway and facilitate breathing by moving the tongue away from the back of the throat and aligning the airway for unobstructed airflow into the lungs.
Yes, you're right miadazalm causes respiratory depression. Coming to the usage, Decisions about medication use should be made on a case-by-case basis, taking into account factors like individual medical history, current health conditions, and potential benefits versus risks.
I had anesthetic gas in both 1971 and 1972 for ear surgery I remember the strong chemical like smell which made it hard to inhale. If any anesthetist or anesthesiologist reads this I'm curious as to what they gave me back at that time. Thanks!!
Those times the inhalation agents used are ether, chloroform, and halothane. They have pungent smell due to its chemical properties. But now we use halogenated ethers, like sevoflurane which has a pleasant smell.
I was just put under Ketamine as an anaesthetic so that the doctors could align my broken and displaced wrist. It’s so hard to describe the experience because its so unlike anything else I’ve ever experienced. It definitely put me under because I felt no pain and have no memory of the procedure happening but it did not feel like I was under at all. I remember looking at the large vitals screen that was in front of me when they gave me the drug. From there the screen had multiple flowing colourful columns going downward and I was travelling down those columns. It was so weird because I guess I was asleep but I felt fully conscience and it wasn’t like I was just feeling like I was travelling down these tubes, I actually was. Anyway it’s really hard to remember but it was something along the lines of I was travelling down these tubes all at the same time and individually and each one would take me to a new vitals screen and a whole new surgery, like I was living all these lives at once. I thought I was going to die. It also felt like a really long time I guess because I was living all these different experiences. I should also mention that I simultaneously had no concept of space, time, where I was, who I was, or anything at all. It was so weird. But I would see that the surgery was happening and sometimes thought I was going to die and then travel through another colourful tube to the “real” or lucid version of what was happening. This happened many times but it was also all happening simultaneously. I finally realised that I was in fact alive and was myself when through blurred vision I saw a cast on my hand and got my wonderful girlfriend to confirm that I did have a cast on. That’s when I regained consciousness because even though I was out I always thought I was conscious and that everything was real.
That sounds like a unique and interesting experience! 😊 Ketamine is indeed used as an anesthetic in certain medical procedures. It's fascinating how it can allow for pain-free surgery while keeping the patient aware of the process. Thanks for sharing your perspective on it! 👍
Open circuit..not used now.. Semi opened circuit as Mapleson system... rebreathing is abolished by high gas flow Semoclosed circuit.... is the closed circuit with high fresh gas flow Closed circuit.... total rebreathing with CO2 absorber
In previous anaesthetics I was given Midazolam or Hypnoval and I experienced anaesthetic awareness which was dreadful. I couldn’t move or feel myself breathe. I then discovered that during my last left sided hernia with mesh operation the Hypnoval was replaced by Ketamine and I still experienced awareness and couldn’t talk. I managed to tense my knees when two nurses were trying to prise them apart and was jabbed inside each thigh with a painful object which I can’t have imagined because post op I noticed a blue bruise inside each thigh. I then couldn’t breath or move and eventually became unconscious. During the operation I felt a sharp pain near my hernia which made me react. The next thing I experienced was a feeling of a ligament on the same side as my hernia “ping” as if it had been cut. I could see my naked body and a nurse throw a blanket over the area. Another dreadful experience! I now have an inguinal hernia on my right side and don’t feel strong enough to go through another procedure as I am in my early seventies, although my consultant said I was healthier than a lot of his 60 or even 50 year old patients. I wonder if you could tell me please if it is necessary to have these drugs along with the usual propofol and painkillers during anaesthetics?Maybe I just have some kind of allergic reaction? I do not take drugs apart from Paracetamol and 8mg codeine for pain which I have lived with since my last left sided inguinal hernia with mesh operation over 10 years ago. Thank you for your interesting video and your hard work.
Intravenous anesthesia drugs like Propofol, Midazolam, and Ketamine can cause allergic reactions, but it's relatively rare. Allergic reactions are possible with any medication, but healthcare providers carefully assess a patient's medical history and allergies to minimize such risks. Consider discussing potential allergies with your healthcare provider to address concerns before surgery 🧑⚕️
my wife is suffering from layrngospasm since last year i.e September 2022. this has happened 7-8 times till now. this is very horrible and like next to death. the breathing stop completely and become unconscious. breathing to be given by mouth. I have consulted General Physician , ENT and pulmonary doctor for this. and presently taken medicine from Neurologist and Gastroenterologist for the treatment. but the real diagnose/ cause cant be ascertained till now. further diabetes is also damaging the immunity. if there is any possible solution available please suggest. and what is the actual cause for the disease
It can be triggered by factors such as gastroesophageal reflux disease (GERD), allergies, irritants, neurological conditions, or psychological stress. First, see your surroundings is there irritants, allergens such as pollen, mold spores, pet dander, and dust mites, which can trigger allergies. Also check the Chemical Irritants, Such as cleaning products, tobacco smoke, and strong odors, occupation irritants and Environmental factors. If not she may be affected with some issue which can indirectly cause Laryngospasm. Since her diagnosis is not clear yet, it's important to continue working closely with the healthcare professionals involved in her care. I hope they can identify the underlying cause soon and provide effective treatment. Wishing her the best of health!
A regular ketamine structure is a racemic mixture of both S (+) and R (−) isomers. This means that it contains equal amounts of both mirror-image forms of ketamine.
@@anesthesiavisions In my country our practices only use 's-ketamin'. I wonder if it has optimal benefits for anesthesic use as the regular. I have limited experience, but it only seems to induce high levels of discomfort due to the dissociation.
In the field of medicine, the conventional racemic mixture of ketamine 🏥🌡️🩺 continues to be the preferred choice for anesthesia and pain management, owing to its well-established safety and efficacy track record. Meanwhile, researchers are actively investigating the potential benefits of S-ketamine 💡🧠 in treating depression, recognizing its unique properties and therapeutic potential. 📊🔍
