What to do when piglets get sick? Choose intraperitoneal injection!
Intraperitoneal injection compared with oral administration and intravenous injection: oral administration is absorbed slowly; if intravenous injection is used in piglets, the veins are thin, making it hard to insert the needle, and it causes great stress on the heart; with intraperitoneal injection, because the peritoneum has a large area and is densely supplied with blood vessels and lymphatic vessels, its absorption capacity is strong, and intraperitoneal fluid replacement takes less time and is fast, making it safe, suitable, time-saving and labor-saving for small piglets. Drugs such as enrofloxacin, ciprofloxacin, gentamicin, and kanamycin can be added to the injected medicinal solution, thereby achieving a effect of treating both symptoms and root causes.
　　
Indications
　　
1. Acute, outbreak-type diseases, with fast drug efficacy and short time required, convenient for rescue, such as piglet poisoning, piglet diarrhea and dehydration, etc.
　　
2. Piglet diseasein the late stage or severe illness with respiratory failure and cardiac weakness requiring fluid replacement but unable to withstand long-term intravenous injection stress, such as swine enzootic pneumonia, etc.
　　
3. Piglets with lowered body temperature requiring fluid replacement and physical warming of the body, such as suckling piglets suffering from cold.
  　　
4. Peritonitis and intestinal inflammation in piglets caused by castration and other reasons.
　　
5. When drug absorption at the piglet's intramuscular injection site is poor due to various reasons.
　　
Operating method
　　
For intraperitoneal injection in piglets, use the inverted-lifting restraint method. The assistant lifts the piglet upside down, with the belly facing the injector, and clamps the piglet's shoulder area between both legs. Insert the needle between the second-to-last and third-to-last rows of teats, on both sides 2-3 cm from the ventral midline, piercing in at a 90-degree angle to the abdominal wall to a depth of about 3 cm. After piercing through the abdominal wall, the resistance to needle insertion disappears; if aspiration shows no blood and no abdominal contents, the medicinal solution can be injected. To facilitate the operation, the injection needle can be a human intravenous push-injection rubber tube needle, or it can be directly connected to an infusion bottle for drip infusion. For sick pigs that are slightly heavier and not easy to lift, lateral recumbency restraint can be used, with the injection site at the flanks on both sides, inserting the needle vertically; after insertion, aspirate to see whether there is blood return and abdominal contents, and then inject. It should be noted that injection with the piglet held upside down in restraint is the safest injection posture.
　　
Precautions
　　
1. The fluid replacement site should avoid the ventral midline, especially in male pigs, so as not to injure the penis.
　　
2. The fluid used for replacement must be an isotonic solution such as 5% glucose solution and 0.9% sodium chloride solution. Hypertonic solutions must not be used, otherwise dehydration will be worsened. Irritating medicinal liquids, such as calcium chloride, sulfonamide drugs, etc., cannot be used for intraperitoneal injection, to avoid causing peritonitis and tissue necrosis.
　　
3. Oil emulsions, drugs with precipitates, and semi-solid preparations are not suitable for intraperitoneal injection.
　　
4. The medicinal solution for fluid replacement needs to be heated to about 37°C.
　　
5. Injection equipment must be strictly disinfected and aseptic operation must be carried out.
　　
6. The pig must be firmly restrained, so as to avoid scratching the intestinal tract, liver, and kidneys during struggling.
