Subcutaneous injection
No matter what the disease is, even if it is just the most common cold, if an injection is needed , and it is impossible to recover with just one injection. Many owners are also unable to take their dogs for injections of medicine on time due to work reasons, causing previous adjustments to be in vain. Therefore, it is also a good choice for pet owners to know the commonly used injection methods. Common injection methods include subcutaneous injection, intramuscular injection, intravenous injection, etc. Different injection methods have different precautions.
1. Subcutaneous injection
The site of subcutaneous injection is often Parts with thin skin, loose subcutaneous tissue and fewer blood vessels are often selected on the neck or upper back. All easily melted, non-irritating drugs, vaccines, and vaccines can be injected subcutaneously. When injecting, you must first hold the dog partially in place, then select a position, and use alcohol to disinfect the site where the injection will be given. Then use your thumb and middle finger to grab the dog's skin, press the center lightly with your index finger to create a fold, and then insert the needle into the fold. The needle should not be inserted too deep or too shallow. Pull back and see if there is any air entering the needle. , if so, it proves that it has not penetrated into the skin. After injecting the medicine, the speed should not be too slow or too fast.
Second, muscle injection
Generally less irritating Both liquids that are difficult to absorb and those that are difficult to absorb can be injected into muscles, but highly irritating drugs, such as calcium chloride, hypertonic saline, etc. cannot be injected into muscles. When injecting into muscles, a site with full muscles and no large blood vessels should be used, usually in the hind legs of dogs. After one person has stabilized and disinfected the dog, the injector uses the thumb and index finger of his left hand to tighten the skin of the injection site, holds the injector in his right hand, and inserts the needle quickly into the skin at an angle of 60 degrees. The depth must also be well controlled and withdrawn. The inner core of the needle can push the medicinal solution into the muscle without blood backflow. After the injection is completed, the part should be disinfected again.
Do not push drugs too fast through intravenous injection
3. Intravenous injection
The efficacy of intravenous injection The fastest, larger dose and irritating liquid (such as calcium chloride, hypertonic glucose solution, hypertonic saline, etc.) should be injected intravenously. The site of intravenous injection can be the cervical vein (inside the jugular groove, in the neck). At the junction of the upper 1/3 and middle 1/3, the veins here are shallow and easy to find), the veins on the inside above the wrist joint or the veins on the inside of the middle part of the palm below the wrist joint, or the veins on the outside of the tarsal joint and above the tarsal joint. veins, medial femoral veins, etc. When injecting, use a rubber tube to ligate the centripetal end of the vein at the injection site to relax the veins. After the local area is trimmed and disinfected, insert the needle flatly into the vein along the longitudinal axis of the vein. If the insertion is accurate, , and quickly see the blood flowing back. At this time, loosen the tight rubber tube, insert the needle further into the blood vessel cavity, then fix the needle, and slowly push the liquid in. After the injection is completed, press the injection site with an alcohol cotton ball. , then pull out the needle and sterilize the area to prevent blood from flowing into the subcutaneous tissue along the needle hole and causing hematoma. Pay attention to the following points when giving intravenous injections:
1. The injector must be matched. , all parts must be carefully connected, the syringe and needle must be smooth and unobstructed, and carefully disinfected
2. Make sure the drug has not expired, and pay attention to the compatibility taboos. .
3. The air bubbles in the needle tube must be drained before injection, and the speed of pushing the medicine liquid out of the blood vessel should be prevented. Too fast.
4. When irritating drugs leak into the subcutaneous tissue, you can generally inject physiological saline or distilled water into the surrounding tissues to dilute the drugs for easy absorption.
