VET SURGEON’S STEADY HAND
We haven’t published any news for a long time. From one hand, it’s wonderful that we are such a busy persons. From the other hand – it seems that nothing interesting had happened. But that is not true. That’s why we are going to tell about our recent trip to Pushino-upon-Oka – the town of peaceful biology.
We were invited by Constantin Lapin, a sensational vet surgeon, but why he is so sensational we’ll tell you later. Some theory first.
Animal testing is unavoidable. Shampoos could be and should be tested on human being’s, but with medicines, unfortunately, it is impossible. Though it’s a great, great pity that many animals should suffer for it. Leaving the bioethics behind, let’s talk numerals. If one animal dies during the tests, it is better than ten animals dying with the same final result of the test. We can take this as an axiom.
Now, imagine that we should trace the influence of some medicine on the organism functions during some periods of time, for example, within an hour, after six hours, after twelve hours, two days later, after a month etc. And to learn the medical impact we need blood tests. Scenario №1 – we have dozen of rats, and we cut one after an hour, cut the other after the six hours, than we take the third one… It is not interesting to continue. But that wasn’t the “Doctor Moreau Chronicles”, that was the ordinary way real practice goes on.
Alternative scenario. We have one rat and take the corresponding number of blood samples from it. Does everybody like blood tests? Fine, you don’t care about animal feelings, but imagine how the creature is stressed, being punctured, and how does it result in biochemical composition of its blood.
Nevertheless, if you install the catheter directly into the jugular vein, then you can tike blood samples any time you want, and the creature will not recognize it. So – up with catheterization! But who is skilled enough for such a target? And what tiny catheter should be used?
..We go on and on endless subterranean tonnels. They divide, some of them turn instantly and disappear while we pass them. We meet people. Sometimes the signposts. But we still go on and on under the ground. Rather associative.
At last, we go up and enter the tidy surgery room. Today two tiny beasts will have surgery. Don’t worry, there will be a happy end.
One – Constantin stretch out to the surface a thin pulsating vein. Two – he enters the vein with the catheter through the microscopic puncture. Three – the proximal end of the catheter (the one with the connector) is fixed above the animal back. The rat is taken to a special cage, where it will wake up. Some time later it will give some blood for the sample, but will not notice it.
And here is the second rat. Comparing to the previous one, it doesn’t feeling well under anesthesia.
One – one more time the vein is stretched out to the surface, but this time it is flat and bloodless. “Ah, I dislike this vein, says Constantin, I dislike it completely. How should I puncture it?” One wrong movement, and a tiny ribbon of flesh, much thinner than one millimeter, will be torn apart and the animal will die. “Ah, I simply hate this vein”, says Constantin, and inserts the catheter directly into it. Three (did we miss the “Two”?) – and a catheter of different construction is fixed above the animal back. Some sewage – and one more rat on the clean sawdust is waiting for the consciousness to regain.
And that is a wonderful new trend. Constantin Lapin wasn’t only the inspirator of microcatheters manufacture – and a special team of professionals, including one of the pioneers of New Age vet medical disposables in Russia, Catherine Zhukova, was involved into the design and development - but also a bright promoter of the method itself, teaching specialists to use the catheterization in their common practice countrywide.
And Mystra…))) as usual is looking forward with some interest and has strong intention to support the expansion of this method in Russia, and also to help some old, antihuman practices to disappear, the faster - the better. Because we like animals.
