How to prevent accidents during pig injection

The injection method is simple to operate and easy to master, but some matters that must be paid attention to are ignored during injection, and it is easy to cause some undue accidents. For example, the injection site is inflamed and suppurated due to lax disinfection of syringes and injection sites or improper site selection, animal bites and fecal contamination. If inflammation occurs, it can be treated according to the treatment of inflammation and suppuration. If you do not pay attention to the safe Baoding of the affected animal before injection, and then carry out the operation, as a result, the livestock will stir and the muscles will contract strongly, or the acupuncture force is uneven, or the needle will be inserted into the tissue with full length, and the needle will be bent and broken, which is more common in intramuscular injection. If you find a curved needle before injection, you can change another needle for re-use, do not straighten the curved needle for re-use. In case the needle is broken, find that there is still a little bit of the needle left outside the skin, you can press down the surrounding skin, when the needle is exposed, fix the needle and take it out with the instrument. If the needle can not touch deep outside the skin, it should be locally anesthetized and the skin should be cut and taken out. In addition, during intravenous injection, when the needle is inserted inaccurately or because of animal commotion, it is easy to leak the injection solution under the skin or in the muscle outside the blood vessels, then the skin and muscle will swell immediately, especially chloral hydrate, calcium chloride and hypertonic saline, which are strongly irritant and leak out of the blood vessels, easily causing tissue inflammation and necrosis. At this time, a part of the liquid leaking out of the blood vessels should be sucked back in time. If calcium chloride leaks subcutaneously, 10% sodium thiosulfate or 10% sodium sulfate can be injected into 10% 20 ml in time to make it non-irritating calcium sulfate and sodium chloride. When there is too much liquid leakage under the skin, it should be cut as soon as possible and drained with hyperosmotic solution, or hot compress with 5% magnesium sulfate or hot vinegar can be applied locally, 4 to 6 times a day, for half an hour each time, to make its circulation exuberant, relieve pain and promote absorption.
