TFP Medical Practice Differences Between Humans and Cybertronians
Ok so, if Ratchet did not acknowledge the differences between humans and cybertronians, he would genuinely kill the human on the operating table.
The Difference Between Energon and Blood Compatability
So, it seems like a good chunk of cybertronians can just inject some of their own blood to another. For example, when Starscream sucked the energon of Bulkhead, he did not have to worry about compatibility. He did not seem to do so and he's not an idiot either. Also, the energon they harvest from the ground, everyone gets.
This lack of thought on blood compatibility (energon is the blood of cybertronians) could get a human killed. See if you were to give a A+ blood to a person whose body makes B- blood and do nothing, they will die. So, let me introduce a medical concept: blood typing. There are four main blood types (there are more but these are the main ones): A, B, O, and Rh factor. What it means to be a blood type is that your body creates antigens. Like if you have B blood type, your body (your immune system) will create antibodies for A antigens since this is not already present in your blood, If you don't have either A or B blood type, then you got O which means that your body makes neither A or B blood type. Rh factor is Rhesus factor. It's the + or - in your blood type. You can't give positive blood to a - blood type. O- is universal donor and AB+ is universal receiver. If a person is given the wrong blood type, the antibodies react with the antigens causing your blood to clump up. This is an ABO incompatibility reaction. Since your blood is clotting, it can shut off the blood supply to vital organs and leave you at risk of excessive bleeding (1).
And I only covered the major blood groups. There are some people who have very rare blood types that they have to be made in a lab. Also, humans only have 4 while horses have 8 (2).
Ratchet, who is the chief medical officer, had no medical concerns about giving Bumblebee his T-cog. It seemed very impromptu his suggestion and he's not that kind of guy. For humans, it's not just the blood types that need to be considered tissue type, medical history, immune system response, and other organ specific stuff. HEAVY EMPHASIS ON THE IMMUNE RESPONSE! The best case scenario of a transplant rejection (where your immune system rejects the transplanted organ) is that it slowly damages the organ which is not why you got an organ transplant in the first place (3).
Given the variety of things that need to be considered, I think you can imagine why it's so hard to get an organ transplant. There's literally a wait-list for getting an organ transplant. In fact, in the U.S alone, 13 people die each day while waiting for an organ transplant (4). May not seem like a lot but if you multiply this by 365 days, that's 4,745 people dying each year waiting for a transplant.
MEANWHILE, cybertronians can exchange parts like it's like ordering parts on Amazon. Like Knockout was literally scrolling through arm options. We ain't going to look at the Tfp Autobots because it well established that they don't have much resources. When Starscream got his arm shot off, Knockout was just like let me help pick out an arm. And Starscream getting an arm that was exactly like his old one.
GIRL, if that was a human who got their arm shot off, they would either have no arm OR a metal prosthetic that's HELLA expensive and needs to be replaced every few months because the socket needs to be fitted. AND if they didn't get a prosthetic, there's a good chance that they will feel phantom limb syndrome.
Sterility in the Operating Room
Ok I'm going to share a video to illustrate my point.
Dr. Glaucomflecken is a med creator. His real name is Dr Flanary. He is an opthomalogist.
Surgeons where TWO gloves and wash their hands till their elbow.
Meanwhile, there was NO prep shown like the process OR ANY SCRUBBING things going on when the T-cog transplant was going to happen between Ratchet and Bumblebee. Arcee was meant to do the operation and WAS SHE CHECKED AND PREPPED FOR STERILITY?!?! Doesn't seem like it. Heck Ratchet, the CMO, only got her to take a decontamination bath when the dark energon got on her. If the CMO suggests only few times, then this suggests that the idea of sterility is different. Like seriously no prep done after Arcee is covered in grime, potential bacteria, viruses and fungi.
How the Work is Divided Up
So, this is going to be more of a headcanon. Cybertronians CAN know everything about the cybertronian body because they don't seem to naturally die. More like something else has to kill them first. Also, cybertronians seems like they get sick less often.
This is not the case for humans. Humans don't live long enough to be trained in all of the human body in great detail. So, they specialize into different parts of the human body. If I'm going to go based off the U.S (the more traditional not all docs have the same path), there is a primary education (K-12) which is 12 years, then undergraduate education which is typically 4 years, then med school which is 4 years and then residency. So, residency is the training for your matched speciality. The amount of training varies but the minimum number of years is 3 years. Let's say that a human were to go undergo training for the main 24 specialties (5). The minimum amount of years if all specialties had a residency had a 3 years (6) (they don't, surgical specialities have a minimum of 5 years), it would be 72 years, which is pretty darn close to the world average of 73.8 years (8) for the human lifespan. I didn't even cover subspecialties. I went for bare minimum training, not complete. Also, humans are pretty susceptible to diseases. I mean the plague in Europe bc of bad hygiene so the whole very decontamination showers don't work.
EDIT (y'all I forgot to add this point)
Ok so cybertronians are born in wells, they don't even have to worry about that.
Meanwhile, organic beings like humans have to. Like, if your biological parents have had cancer or they have risk of cancer, that risk will be passed down to you. Biological parents can even pass down diseases or disorders to you.
To explain how diseases or disorders are passed down, I'm going to give you a biology lesson on dominant and recessive traits.
So you have two copies of a gene. Depending on whether it is a recessive or dominant trait, that will code for a certain trait. What a recessive trait means is that you need to have two copies of the gene so it codes for a trait or disease. For example, sickle cell disease (where your blood cell trait isn't circular rather like a crescent shape), is a autosomal recessive disease. This means that you need two copies of the sickle cell trait to get it. Either your both your biological parents are carriers meaning they each carry one copy of the gene and then you get the combination of having two copies of the sickle cell trait. Or both your biological parents have sickle cell, so you have it.
Then there is the dominant trait. For a trait to be dominant, you only need one copy of this trait and then you have it. An example of this is Huntington's disease (your nerve cells in the brain decay over time). Huntington's disease is an autosomal disease, you need one biological parent to have it.
