subcutaneous injection
No matter what disease, even if it is just the most common cold, if you need to get an injection, it is impossible to heal only once. Many owners can not take the dog to inject the medicine on time because of their work, so that the previous treatment is to be dotted. Therefore, mastering the commonly used injection method is also a good choice for the owner. Common injection methods include subcutaneous injection, muscle injection, venous injection, etc. Different injections have different precautions.
I. Subcutaneous injection
The parts of the subcutaneous injection are usually selected from parts with thinner skin, loose subcutaneous tissue, and less blood vessels, and usually choose some positions on the neck or back. Anyone -soluble, non -irritating drugs, and bacteria and vaccines can be injected subcutaneously. When injecting, first keep the dogs alone, then select the position, and disinfect the injection site with alcohol. Then use the thumb and middle finger to grab the dog's skin, the index finger is gently pressed to form a fold, and then insert the needle into the folds. Do not enter the needle too deep or too shallow. If so, it shows that it has not been tied under the skin. Push the medicine after tie, the speed should not be too slow or too fast.
Two, muscle injection
Generally, liquid solution and liquid liquid that are lighter can be used for muscle injection, but drugs with strong irritation, such as calcium chloride, high osmotic saline, etc. cannot be injected with muscle injection. In muscle injection, the muscle should be plump and non -large blood vessels, usually in the hind legs of the dog. After one person guarantees the dog and disinfected, the injectioner tighten the skin of the injection part with the thumb and index finger of the left hand, and hold the injectioner in the right hand to quickly pierce the needle and the skin into a 60 -degree angle. Core, without blood flow, can push the medicinal liquid into the muscles. After the injection is completed, the part should be disinfected again.
Varicose injection push drugs do not be too fast
Three, intravenous injection
The efficacy produced by intravenous injection is the fastest, with large dosage and irritating medicinal solution (such as calcium chloride, hypertonous glucose solution, high osmotic saline, etc.). The part of the vein injection can be selected at the junction of the neck vein (in the neck ditch, 1/3 of the neck and the middle of the middle, the vein is shallow here, easy to find), the inner side or below the middle of the palm of the wrist joint, The vein in the inner side, or the outer side of the joint, the vein above the joint of the joint, the veins on the inside of the stock. During the injection, the vein of the vein of the injection site is used to make the vein anger anger with the vein of the injection site. After the local cutting hair is disinfected, the needle is pierced into the vein along the veins of the vein. At this time, the tight rubber tube was released, the needle pierced the needle in the blood, and then fixed the needle to slowly push the medicinal liquid. After the injection is completed, you must press the injection site with alcohol cotton balls, and then pull out the needle to disinfect it to prevent blood from flowing into the skin to form hematoma. Pay attention to the following content when intravenous injection:
1. The syringe must be matched, each component is tightly connected, and the syringes and needles must be unobstructed and strictly disinfected.
2. To determine that the drug is not over the shelf life, and pay attention to compatibility taboos.
3. Before the injection, you must exhale the bubbles inside the needle, and prevent the medicinal liquid from leaking out of the blood vessels during injection. Do not be too fast for pushing the medicinal solution.
4. When a irritating drug is leaking under the skin, it can generally inject physiological saline or distilled water into the surrounding tissue, which is easy to absorb the drug.
