Intravenous simply
means "within vein" (or "inside the vein"). Therapies
administered intravenously are often included in the designation of specialty
drugs. Intravenous infusions are commonly referred to as drips because many
systems of administration employ a drip chamber, which prevents air from entering
the blood stream (air embolism), and allows an estimation of flow rate.
Intravenous
therapy may be used to correct electrolyte imbalances, to deliver medications,
for blood transfusion or as fluid replacement to correct, for example,
dehydration. Intravenous therapy can also be used for chemotherapy.
Compared with
other routes of administration, the intravenous route is the fastest way to
deliver fluids and medications throughout the body. The bioavailability of the
medication is 100% in IV therapy.
Intravenous
infusions are fluid solutions administered through a vein. There are numerous
different types of solutions available, but they can be broken down into simple
categories depending on the function they serve. Some replace lost fluids, and
others provide nutrients, replace lost blood, and deliver medications.
One of the most
common uses for intravenous infusions is to replenish fluids lost through
dehydration. These infusions often contain normal saline solution, a
combination of sterile water and sodium chloride. This solution is known as an
isotonic crystalloid, or a solution that contains the same amount of
electrolytes as plasma in the body. It is used in cases of moderate to severe
dehydration, such as that caused by vomiting or diarrhea, when replacing the
fluids quickly is vital.
When a patient`s
gastrointestinal tract is compromised and nutrients cannot be absorbed - or
eating can worsen the condition - intravenous infusions called total parenteral
nutrition may be given. These solutions contain a mix of sterile water,
electrolytes, sugar, proteins, fats, and other nutrients, depending on the
needs of the patient. Diseases and disorders that commonly require total
parenteral nutrition include late stages of Crohn`s disease, obstructive bowel
disorder, and ulcerative colitis.
Intravenous
infusions are also used to deliver medication directly to the blood stream.
Certain medications, such as intravenous immunoglobulin, a type of antibody,
can only be given through the vein. Other medications, such as certain narcotic
pain relievers, are given intravenously because the method allows them to they
work faster than when taken orally. Chemotherapy for treatment of cancer is
also typically given intravenously.
When performed by
a medical professional, intravenous infusions are typically safe. The most
common reaction is mild pain and redness at the site of the injection, although
different medications may cause different side effects. Any time the skin is
punctured, there is a risk of infection. Having a medical professional,
typically a nurse, monitor the Intravenous Infusion and change the injection
site when irritation is evident can help prevent complications.

1. The pond conditions are generally selected from the ponds that can be used for fish cultivation or the water-raising breeding ponds that are constructed by digging trenches around the low-yield farmland. The area is not limited. In order to facilitate network operation, generally about 20 acres is appropriate, water depth 1.5 meters to 1.8 meters, requires a quiet environment, water and land transportation facilities, adequate water supply, water quality fresh and pollution-free.
2. Prepare the pond for pumping water in the beginning of May to remove silt. Use 100g of lime for each mu and 50kg of tea seed cake to dissolve and soak. Then, the whole pool should be splashed with sprinkling. After filtered water injection, plant Vallisneria, Elodea, and water peanuts are planted in the pool. For aquatic plants, 250 to 300 kilograms of fresh snails are placed per mu.
3. Auxiliary facilities Surrounding the pond with asbestos tiles as an anti-fence wall, about 5% of the area of ​​the pond is blocked with plastic film as the second desalination pool for white shrimps of South America. At the same time, according to the size of the pond, it is equipped with pumping equipment, aerators and other mechanical equipment.
1. The stocked shrimp and crab seed were stocked in mid-May and stocked. Quarantine-free, healthy virus-free shrimp seedlings, 1.5 cm to 2 cm in size, oxygenated with an oxygen bag, and the returned shrimps adapted to the water temperature in the holding tank and soaked in formalin for 2 minutes ~ 3 minutes (20 grams per ton of water). During the holding period, attention should be paid to adjusting the water temperature and water quality, feeding special opening feeds, and raising the plastic film and membrane barriers into the big pond for 15 days after the temporary raising. The crabs were purchased with approximately 1000 eggs per kilogram of young crabs cultivated in the same year. The species size is about 15 cm. The stocking rate per acre was 15,000 to 20,000 tailed shrimps, 600 to 800 juvenile crabs, 50 fishes and breams.
2. After feeding the shrimp into the pond, the feed can be fed with special shrimp or crab feed, or can be fed with self-made feed (feed formula: fish meal or dry powder or blood meal 17%, bean cake 40%, bran 30%, secondary powder 10%, 3% of bone meal or shell powder, plus 1 ton of special multivitamins and 2% of adhesive), 3% to 5% of the weight of shrimp, crab, daily intake, 7 am It is 1/3 of the total daily feeding time between 8:00 am and 8:00 am. The rest is fed from 3:00 pm to 4:00 pm. During the later period, some freshly-cracked live snails, squid, and chopped pumpkin and potatoes are added as shrimp. Crab supplements.
3. Daily management During the whole breeding period, the water quality is always maintained to meet the requirements of fertilizer, living, tender and cool. In the hot season, water or water is changed in time so that the transparency of the pool water reaches 30 cm to 35 cm. Adhere to the patrol once a day in the morning and evening, check the water quality, dissolved oxygen, shrimp and crab eating and activities, often clear the enemy, splash lime slurry every 20 days, and use 10 to 15 kg of lime per acre to prevent fish Shrimp and crab disease and regulate the pH of the pool water. Usually add some chitin, Chinese herbal medicine, etc. in the feed of shrimps and crabs to play a role in preventing disease and promoting clam shell.
4. After feeding for 120 days, the white shrimp can be harvested when it grows to 12 cm to 15 cm in length. The nets, cages, shrimp trawls and other tools can be used to catch small fish. When the water temperature is below 18°C, the water pool is drained. shrimp. The crabs were taken in the pool at night and the crabs were caught by hand and caught in cages. The crabs were washed in time and raised for sale.
