Snake Documentaries

In order to give me more understanding about rattlesnakes, rattlesnakes bites and also other snake bites, I have watched documentaries about them and this helps me and gives me ideas of how I should do my snake bite project.
On the documentary above, it has explained that the venom from the snakes will never runs out from them. In the video, it also shows a man was bitten by a snake on his leg and the venom breaks down the cell and tissues in his body. His legs was swollen fast and later on in the video shows that the patient has survived for the night and the nurse injected the anti venom to the area he got bitten. You can see the skin was swollen and it turns to dark purplish color and there are reddish color around the wound as well. 

The documentary from above is about snake venom and the biologist tries to find out how and why venom exists. It's really interesting to look at how the venom reacts to the blood, in the video, the biologist has put his blood into two containers. He then compare the difference between one with venom added to his blood and one without. The one that he has put venom with his blood turn into solid form and the one without venom still remain liquid. The blood turn into solid which means that it will cause internal and external bleeding in your body including gums, ears and nose, etc. 

Venom is a deadly chemicals and it comes from the snakes' fangs which are the hyprodermic needles and allows venom to flow under extreme pressure. The biologists have discovered the first snake in the world has no fangs but they have venom. There are three major groups of snake and they are solenoglyphous,  proteroglyphous and opisthoglyphous and they have very different types of fangs. 

 Flesh eating Snakebite
This video shows a more serious conditions that the victim has got after bitten by a snake.  In the beginning of the video, the victim's finger has turned into black in color which shows the dead skin but then later on in the video, the doctor found out that underneath the dead skin, it is liquefy with flush and tiny pieces of bones which shows the venom has gone under the tissue distraction. After that, the doctor came up an idea to cover the wound with the skin and later on in the video, you can see the victim's finger has got black eschar and start healing.  

Rattlesnake Compartment Syndrome

 From the video, you can see the victim's skin caused by the snake bite (the area he has got bitten) turns black on his skin and it looks like it is rotten. The skin was stretched as the swelling getting bigger and they have done the first surgery to cut the skin and split it open. You can see the muscles and the skin is split open on his forearm and hand. The victim also said the skin is so hard for the doctors to cut because of the swelling problem. He lied in a machine which helps the heeling process of his wound. After several days, he did another surgery to close the wound and there are clearly seen scars on his arm.

 The video has explained how the venom has caused and also how the venom effect after the snakes have attacked and eat the animals. As applied to human, as soon as the rattlesnake strikes, the toxins will then inject and they rely on the hollow fang to let the venom flow into the wound and break down the tissue. The tissue then absorb the venom and after it has injected to the skin, the venom will become less viscous because of the tension on the skin and so that's why the venom can expanded to other parts of the body very quickly. 

Rattlesnake Bite Symptoms

 In this video, the doctor has explained that after getting a snake bite, people will feel more and more in pain as the amounts of swelling on the skin. The video also explain what compartment syndrome is and it mean 'when severe swelling cuts off blood supply to the muscles.' and the treatment of this is to let 'Surgeons treat this by proactively slicing open this swollen tissue, an operation known as a fasciotomy.' 
Also, the video has got an interview with the snakebite victim Pippen Graves, who describe his experience  and the symptoms he got after bitten by a rattlesnake. He felt panic, dizzy, trouble to breath and there is toxic reactions within his body. 

Rattlesnake Bite Recovery

 In this video, the doctor has explained that Rattlesnakes has a sense of heat detection on their face and they can see heat and identify them. After getting a snake bite, the whole body is infected and it will cause internal bleeding (such as lungs, etc and sometimes even brain) and also external bleeding. There is an interview with Ralph Prado, who was bitten by a Southern Pacific Rattlesnake and he has made a recovery from the bite. He explains that he saw he's bleeding everywhere and he needed over 60 vials of anti-venom. An average rattlesnake bite requires 4 vials of anti-venom and so you can compare how serious and dangerous Ralph Prado's conditions was in after he was bitten by the snake. His fasciculations persisted for 5 days and on the 6th day, he finally regained consciousness.
