What is the treatment method of venous leakage in pigs, cattle and sheep?

1, when the liquid medicine leaks, the needle moves out of the blood vessel and the liquid medicine leaks (flows) into the skin. If this situation is found, stop the injection immediately and try to extract the leaked liquid medicine with a syringe. Such as calcium chloride, calcium gluconate, chloral hydrate and hypertonic saline, etc., and inject l0% sodium thiosulfate or l0% sodium sulfate (or magnesium sulfate) 10 ~ 20ml into the leaked part. 5% magnesium sulfate can also be used for local hot compress to promote the absorption of exudate, relieve pain and avoid local necrosis.

2. Broken needle usually occurs during intramuscular injection. Due to animal disturbance, muscle tension or uneven stress during injection. Once it happens, take out the broken needle as soon as possible. When the broken needle is exposed to the skin, use hemostatic forceps and other instruments to clamp the broken needle and pull it out. When the decapitation is deep, Baoding animals, after local anesthesia, are cut open by surgery and taken out at the eye of the needle.
