Rules for diluting antibiotics. Standard dilution of antibiotics How penicillin is diluted for injection

Introduction antibacterial agents It is used intravenously or intramuscularly for moderate to severe disease.

• Parenteral administration allows:
• significantly increase the bioavailability of the product used;
• accelerate the achievement of maximum therapeutic concentrations in plasma and obtain a visible therapeutic effect much faster;
• exclude the effect of digestive system enzymes on the drug;
• provide first aid to unconscious patients with uncontrollable vomiting or dysphagia (impaired swallowing);

use drugs that are poorly absorbed or destroyed in the gastrointestinal tract.

Antibiotic injections must be performed in a hospital setting. The attending physician must prescribe medications, as well as calculate the dosage of antibiotic required for administration. Antibiotic dosages are selected individually and depend on the age, weight and severity of the patient’s condition. To prevent the development allergic reactions (Quincke's edema, anaphylactic shock

), all antibiotics are administered only after a sensitivity test has been performed.

Independent choice of the drug and selection of dosages can cause the development of severe side effects.

Before diluting the drug, the nurse should check the labels on the ampoule with the prescription sheet, and also check the expiration date of the ampoule. The packaging with the syringe must be checked for integrity and expiration date. Then a thorough hand hygiene is carried out. After the gloves are put on, they are treated with an alcohol ball.

The package with the syringe must be opened from the piston side. After opening the package, you should connect the needle to the syringe (the protective cap cannot be removed from the needle).

Next, you need to remove the protective cap from the needle, draw the required solvent into the syringe (injection water, isotonic physiological solution). After piercing the rubber stopper with a needle, you need to carefully introduce the liquid into the bottle.

After disconnecting the syringe from the needle (the needle remains in the cap), the bottle must be thoroughly shaken until the antibiotic is completely dissolved.

The dissolved drug must be homogeneous, transparent and free of foreign matter. For some antibiotics, a yellowish tint of the solution is allowed.

After the antibiotic has completely dissolved, you need to connect the syringe back to the needle, turn the bottle over and draw out the required amount of medicine.

After collecting the solution, you need to make sure that there are no air bubbles in it. If necessary, turn the syringe over with the needle up, lightly tap the barrel (so that the bubbles rise up) and release the air bubbles.

How to calculate the dose of an antibiotic

Two dilution methods are used - 1:1 and 2:1.

In pediatric practice, a one-to-one dilution is used, and for adults, a two-to-one dilution.

To correctly calculate the dose, you must remember that 1,000,000 units of the drug is equal to 1,000 milligrams (1 gram). Accordingly, 0.5 grams = 500,000 units, 0.25 grams = 250,000 units.

When diluting an antibiotic using the one-to-one method, 1 milliliter of solvent is used per 100,000 units of antibiotic. Accordingly, to dilute 250 thousand units of the drug, add 2.5 milliliters, 500 thousand - five milliliters, 1 million units - 10 milliliters of solvent.

Antibiotic dilution and calculation required dose in neonatology it is also carried out on a one-to-one basis.

If an antibiotic is diluted at a ratio of two to one, then 0.5 milliliters of solvent is used per hundred thousand units of the drug.

Accordingly, for 250 thousand units 1.25 of solvent is taken, for 500 thousand - 2.5 and for 1 million units - 5 milliliters of solvent.

Rules for diluting antibiotics

When using the one-to-one dilution method, it must be taken into account that each milliliter of the resulting solution will contain 100 thousand units or 100 milligrams of the drug. Accordingly, every 0.1 milliliter of solution contains 1000 units or ten milligrams of the drug.

The antibiotic solution must be prepared immediately before administration.
Calculation example:

Given medicine belongs to the group antibacterial drugs. It helps rid the animal of the active development and reproduction of pathogenic microorganisms. The active ingredient in Penicillin for chickens is benzylpenicillin sodium salt. The medicine is available in the form of a white or yellowish powder that easily dissolves in water.

The cost of Penicillin is approximately 11 rubles. This is the price of 1 bottle.

Note! The drug has anti-inflammatory, antimicrobial and antiviral effects on the body of the affected chicken. It is quite effective and, at the same time, cheap drug.

Indications for use

This medicine is used to treat infectious diseases in chickens It effectively fights many pathogenic microorganisms, namely:

• streptococci;
• staphylococci;
• enterococci;
• pneumococci;
• Moningococcus.

That's why Penicillin should be used in the treatment of chickens and those diagnosed with the following diseases:

These diseases develop rapidly, so an experienced chicken breeder will notice them at the first ailments of poultry. Once a sick chicken is discovered, treatment must begin immediately. In this case, sick chickens should be isolated from healthy animals, since infectious diseases are quickly transmitted by airborne droplets.

Required amount of drug

To combat infectious diseases in chickens, it is necessary to use this drug by intramuscular injection. To do this, you must first dilute penicillin for chickens with sterilized water.

Depending on the age of the sick animal, this needs to be done in the following ways:

1. Young chickens should be treated with Penicillin, dissolving the powder in a 0.5% solution of novocaine or in purified sterilized water. Single dose for intramuscular administration is 50,000 units per 1 kg of animal body weight.
2. Adult chickens need to be diluted with 30,000 units of penicillin per 1 kg of body weight.

The duration of such treatment should be no more than 1 week. If the chicken has a severe form of an infectious disease, then this period must be extended to 10 days. In this case, for maximum effectiveness, the drug can be administered intravenously, reducing its dosage by 2 times.

REFERENCE! The medicine can also be used as an aerosol, which will help quickly restore the normal state of a sick chicken. The dosage remains unchanged.

Signs and actions in case of overdose

Using this drug in excessive amounts may cause allergic manifestations in the form of urticaria, pharyngitis or dermatitis. If such symptoms are observed in a sick animal, then the only action that the chicken breeder should take is to completely stop treating the chicken with Penicillin.

Also for 3-5 days, the affected chicken should be given antihistamines. After full recovery A chicken should not eat the eggs it lays for 2 days. If the slaughter of the animal was planned, then it should be postponed for 3 days.

Penicillin in eliminating infectious diseases poultry is very effective and also accessible means to date.

Synonyms: Baclofen, Lioresal, Penbak, Penglob.

Pharmachologic effect. Semi-synthetic antibiotic from the penicillin group for oral administration. It has a bacteriolytic (bacteria-destroying) effect. Has a wide spectrum of action, including gram-positive (streptococci, pneumococci, staphylococci that do not produce penicillinase -

an enzyme that destroys penicillins) and gram-negative microorganisms (enterococci, gonococci, Escherichia coli and Haemophilus influenzae, as well as Branhamella catarralis, Proteus mirabilis, Shigella species). Acid-resistant, does not break down in the intestines.

Indications for use. Bacterial infections: bronchitis (inflammation of the bronchi), pneumonia (inflammation of the lungs), dysentery, salmonellosis, colienteritis (inflammation small intestine caused by coli), pyelonephritis (inflammation of kidney tissue and renal pelvis), purulent infections of the skin and soft.

Purpose: parenteral administration of drugs.

Indications: doctor's prescription.

Contraindications: expired medicinal product, violation of the sterility of the bottle.

Equipment: bottle of medicines, syringe with needle; 70% alcohol, cotton balls, scissors.

Rules for diluting antibiotics:

Solvents: 0.25% or 0.5% novocaine solution, 0.9% sodium solution chloride, sterile water for injection.

The most popular antibiotic is penicillin (benzylpenicillin sodium or potassium salt). It is available in bottles, units. Dosed in action units.

1 ml of solution should contain a unit of penicillin

Thus, if the bottle contains ED, then you need to take 5 ml of novocaine.

Algorithm of actions of the nurse:

1. Read the name on the bottle.

Intramuscular administration of penicillin, especially in massive doses and for a long time, can lead to aseptic infiltrates at the injection site. Aseptic infiltrates occur as a result of hemorrhages at the injection site and compression of the vessels feeding the tissue. In the latter cases, tissue necrosis develops. More often, necrosis is observed in infants and when the depth of needle insertion is insufficient (if solutions enter the subcutaneous fatty tissue). Therefore, injections should be done slowly. The occurrence of infiltrates is usually not a contraindication for further injections, but it requires appropriate measures to be taken. Resorption of infiltrates is promoted thermal procedures: paraffin and ozokerite applications and UHF. The use of compresses is undesirable, as they lead to maceration of the skin in the injection area. Less commonly, septic abscesses occur at injection sites of penicillin or other antibiotics, caused by resistant staphylococci that fall on the needle.

Most often, antibiotics are administered intramuscularly. Antibiotics for injection are produced in the form of crystalline powder in special bottles. Before use, it is dissolved in a sterile isotonic solution of sodium chloride (saline solution 0.9% sodium chloride), water for injection or 0.5% novocaine solution.

Let's look at the rules for diluting antibiotics.

The most popular antibiotic is penicillin (benzylpenicillin sodium or potassium salt). It is available in bottles, units. Dosed in action units.

Cefotaxime is used to treat pneumonia, meningitis, blood poisoning, endocarditis, infections genitourinary system, bones and joints. The use of this antibiotic in patients with immunodeficiency is also effective.

Dosage and dilution of cefotaxime

Before diluting cefotaxime, its dose is calculated, it depends.

Instructions for use

Rules for choosing benzylpenicillin salt

Dilution of Benzylpenicillin

• Sterile water for injection (can be used for any type of injection - intravenous, intramuscular, lumbar, subconjunctival, etc.);
• Saline solution (used only for preparing solutions for intravenous, intramuscular, lumbar, pleural, subcutaneous administration);
• 2.5% and 5% Novocaine (used only for preparing a solution for intramuscular injection);
• 5% glucose (used only for preparing solutions for intravenous infusions, so-called “droppers”).

To prepare a solution for injection, select a suitable solvent and draw it into a sterile syringe in a volume of 1–3 ml if intramuscular administration is planned, or 5–10 ml for any other type of injection (intravenous, pleural, etc.). Then remove the top aluminum cap from the bottle with benzylpenicillin powder with the required dosage. Using the needle of a syringe with a solvent, pierce the rubber stopper of the bottle with benzylpenicillin powder and carefully release the entire volume of liquid. After this, the needle is raised above the surface of the liquid and the bottle is gently shaken until the powder is completely dissolved. When a clear solution without impurities or flakes is formed in the bottle, stop shaking. When using Novocaine as a solvent, the finished solution may be slightly cloudy, but without flakes. Next, lower the syringe needle to the very bottom of the bottle and draw the entire volume of the solution into it. Then the needle is removed from the stopper and the injection is made.

• Sterile water for injection;
• Saline;
• 2.5% and 5% Novocain.

To prepare the solution, take 5 ml of the selected solvent into a sterile syringe, remove the aluminum foil from the bottle with the powder and pierce the rubber stopper with a needle. Then the entire volume of the solvent is released into a bottle with powder and gently shaken until it forms clear solution. After this, draw the entire volume of the resulting solution into a syringe, remove the needle from the stopper and perform the injection.

Methods of administration of benzylpenicillin salts

• Intramuscularly;
• Intravenously;
• Subcutaneously;
• Pleural (in the pleura of the lung);
• Lumbar (into the spinal canal);
• Subconjunctival (in the eye tissue);
• IN ear canal ear in the form of drops;
• In the nasal passages in the form of drops;
• Intraorgan (introduced directly into the tissue of an organ during surgery).

During therapy, you can change the method of administration of benzylpenicillin drugs or combine them if necessary. For example, at the beginning of therapy, benzylpenicillin can be administered intravenously to quickly achieve therapeutic effect, and after a few days switch to intramuscular injections etc.

How to dilute penicillin correctly

Typically, penicillin antibiotics are produced in powder form, packaged in special bottles and in this form supplied to pharmacies and medical institutions. As a rule, any solution prepared from these powders is subject to rapid decomposition, so it is usually recommended to dilute penicillin immediately before using it. At the same time, it is not allowed to dilute penicillin with other drugs, except for the liquid in which its powder was mixed. The rule is relevant even when such drugs are used together in complex therapy.

Before asking a patient to dilute penicillin for appropriate injections, the physician will likely weigh possible risks, the hypothetical harm of using just such an antibiotic and the benefits it can bring. If the former are outweighed, another antibiotic will almost certainly be prescribed. In case the best option such injections will be recognized, penicillin for their implementation will be diluted in novocaine, so-called. injection water and saline solution (water with sodium chloride). Each of them has its own dosage prescribed.

If it is intended to dilute penicillin with novocaine, it is permissible to use a 0.25-, 0.5- or 1% solution of the latter, depending on medical prescriptions. For one-time mixing, thousand are taken. units of the antibiotic itself. The dosage in each case is prescribed strictly individually, based on the age of the sick person and the nature of the disease. Don’t worry if you dilute penicillin with novocaine and the resulting solution becomes a little cloudy. Such a reaction in this case is considered normal.

As for the volume of novocaine in which penicillin should be diluted, these drugs are usually combined at the rate of 5-10 thousand units of the latter per milliliter of the former. By the way, approximately the same proportion is observed when it is prescribed to dilute penicillin with other substances: sterile injection water or saline solution. In this case, you should definitely adhere to a certain daily dosage of the drug. For adults, its maximum is 500 thousand-2 million units, based on the characteristics of the disease, for children - no more than 60 thousand units. for every kilogram of body weight.

For certain ailments: inflammation of the head or spinal cord etc., endolumbar (into the spine) injections are required. In this case, it is also recommended to dilute penicillin with cerebrospinal fluid - the spinal cord fluid of the patient himself. For 3-4 ml of a regular penicillin solution, a similar volume of cerebrospinal fluid is taken, and thus an injection is made, strictly according to medical prescriptions and only medical personnel. Penicillin is also diluted to create eye drops. Then fill the bottle with penicillin completely, but without the top, with saline solution or injection water and stir well.

Penicillin (in solution with novocaine)

In a solution with novocaine (-IU penicillin and 1 ml of 0.25-0.5-1% novocaine solution), penicillin is administered intramuscularly up to 5 times a day.

Penicillin can be used in combination with other antibiotics and sulfa drugs. Combination therapy may contribute to greater effectiveness of drugs, prevention of the development of resistant forms of bacteria, etc.

At the same time, it is also possible to strengthen side effect. Endolumbarally crystalline sodium salt of benzylpenicillin is administered at inflammatory diseases brain and spinal cord and meninges, inflammatory processes after injuries and operations on the central nervous system.

Depending on the age of the patient and the nature of the disease, ODOED is administered endolumbarally once a day. Children under 1 year are prescribed ED per day, from 1 year to 2 years - ED, from 2 to 3 years - ED, from 4 to 8 years - ED, over 8 years - ED. Adults are administered 70,000 units, but not more than one unit per day.

Dilute penicillin in 3-10 ml (depending on the amount of penicillin) of sterile double-distilled water or sterile isotonic sodium chloride solution.

If the volume of penicillin solution is small (3-4 ml), an additional 3-4 ml is drawn into the syringe cerebrospinal fluid. Before administering the solution, 5-10 ml of cerebrospinal fluid is removed. The drug is administered slowly, over 1-2 minutes. Simultaneously with endolumbar administration, penicillin is injected into the muscles in normal doses.

Alexander Fleming

It was this Scottish scientist who discovered penicillin. Born August 6, 1881. After leaving school he graduated from the Royal College of Surgeons, after which he remained to work there. After England entered the First world war, became captain of the Royal Army Military Hospital. After the war, he worked on isolating pathogens of infectious diseases, as well as on methods to combat them.

History of the discovery of penicillin

Fleming's worst enemy in his laboratory was mold. A common gray-green mold that affects walls and corners of poorly ventilated and damp rooms. More than once, Fleming lifted the lid of a Petri dish and then noticed with annoyance that the streptococcal cultures he was growing were covered with a layer of mold. As soon as the bowl with the biomaterial was left in the laboratory for a few hours, the nutrient layer on which the bacteria grew immediately became covered with mold. As soon as the scientist did not fight with her, everything was in vain. But one day, on one of the moldy bowls, he noticed a strange phenomenon. A small bald patch has formed around the colony of bacteria. He was under the impression that bacteria simply could not multiply in moldy areas. The antibacterial effect of mold has been known since ancient times. The first mention of the use of mold for treatment purulent diseases were mentioned in the works of Avicenna.

Discovery of penicillin

Having saved the “strange” mold, Fleming grew an entire colony from it. As his research showed, streptococci and staphylococci were unable to develop in the presence of this mold. Having previously carried out various experiments, Fleming concluded that under the influence of some bacteria others die. He called this phenomenon antibiosis. He had no doubt that in the case of mold, he had encountered the phenomenon of antibiosis with his own eyes. After careful research, he was finally able to isolate an antimicrobial drug from the mold. Fleming named the substance penicillin in honor of Latin name the type of mold from which he isolated it. Thus, in 1929, in the dark laboratory of St. Mary's Hospital, the well-known penicillin was born. In 1945, Alexander Fleming, as well as scientists who established industrial production penicillin, Howard Frey and Ernest Chain were awarded the Nobel Prize.

Industrial production of the drug

Fleming's attempts to establish industrial production of penicillin were in vain. Only in 1939, two Oxford scientists, Howard Frey and Ernest Chain, after several years of work, were able to achieve noticeable success. They obtained a few grams of crystalline penicillin, after which they began the first tests. The first person whose life was saved by administering penicillin was a 15-year-old boy suffering from blood poisoning.

How to dilute penicillin?

Antibiotics of the penicillin series are among the oldest, are low-toxic and have high antibacterial activity. A sufficient amount of penicillins can only be taken by injection, since they are destroyed in an acidic environment, then their effect is not noticeable.

Penicillin is prescribed for inflammatory processes caused by streptococci and staphylococci. Spirochetes, pneumococci.

Penicillin antibiotics are available in powder form and sold in bottles. For intramuscular administration, the powder must be diluted immediately before injection, since the diluted solution quickly decomposes. It is eliminated from the body very quickly; very frequent administration over a course of five to seven days is required.

Powder for injection must be diluted with isotonic solution, water for injection or novocaine.

It can be diluted with any solvent, but it must be taken into account that novocaine is an anesthetic, but penicillin diluted with novocaine may become cloudy, this does not affect the quality of the medicine. Keep in mind that novocaine ndash; allergen. You must know your body's reaction to such a remedy.

If you need to administer 250 mg of oxacillin sodium intramuscularly, then this amount is diluted with 1.5 ml of water for injection, 500 mg ndash; 3 ml water.

Ampicillin sodium and ampiox sodium are also diluted with water for injection; for this, 2 ml of solvent is taken per bottle of powder.

Penicillin: how to dilute correctly?

IN modern times in the fight against various diseases, including purulent ones, penicillin is widely used. This drug is obtained from an extract of mold fungi, and its effectiveness has already been proven.

Penicillin is an antibiotic, that is, antiviral and antimicrobial agent wide range actions. It is produced in powder form. This begs the question, if the powder on sale is penicillin, how to dilute such a drug. In diluted form, penicillin does not participate in cell breakdown processes and is not adsorbed in the liver. It is these properties that distinguish it from many others. medicines. Therefore, penicillin is the maximum effective remedy, which is not harmful to health.

This medicine is widely used for purulent inflammations, conjunctivitis, infections. Few people know how to make penicillin. Penicillin is mainly used intramuscularly. Of course, we can take it orally in a diluted form, but only under the supervision of a doctor. Penicillin is diluted immediately before use. Depending on the severity and nature inflammatory process, the dosage of drug dilution may vary. For example, for each disease, penicillin, how to inject and in what dosage is prescribed by the doctor, and you must follow his recommendations when using this drug. Penicillin is always diluted with saline solution (sodium chloride) and novocaine. When administered by drip, penicillin is diluted with glucose.

If it is necessary to use penicillin intramuscularly, it is necessary to clearly consider possible harm for health and its fundamental benefits. Therefore, before you get penicillin at the pharmacy, you should read the instructions. The standard penicillin dilution scheme looks like this: 1:1/3:1/3. That is, one dose of penicillin, one third of the dosage of antibiotic, sodium chloride and one third of novocaine. Changes in the dosage of the drug can only be adjusted by a doctor.

Each person was directly exposed to penicillin at home. What is penicillin, how to get this miracle drug, many would like to know. In principle, penicillin is a mold fungus that everyone has repeatedly encountered when bread and other products spoil, but the use of such penicillin is not safe. It is important to remember that for any disease, you must contact a specialist; you should not self-medicate.

Description

Amorphous or fine crystalline powder white, soluble in water, alcohol, ether and acetone.

Compound

1 bottle of the drug contains active substance: benzylpenicillin sodium salt - 1,000,000 units.

pharmachologic effect

Benzylpenicillin is active against gram-positive microorganisms (staphylococci, streptococci, pneumococci, anaerobic bacilli, anthrax bacilli), gram-negative cocci (gonococci, meningococci), as well as against spirochetes, some actinomycetes and other microorganisms.

Benzylpenicillin for intramuscular injection quickly absorbed into the blood and detected in body fluids and tissues; penetrates into the cerebrospinal fluid in small quantities. The maximum concentration in the blood is observed after intramuscular administration after 30-60 minutes. 3-4 hours after a single intramuscular or subcutaneous injection, only traces of the antibiotic appear in the blood. To maintain concentration at a level quite high for a therapeutic effect, injections must be given every 3-4 hours. At intravenous administration the concentration of penicillin in the blood decreases rapidly. Bacteria of the enteric typhoid group, Brucella, mycobacteria, protozoa, viruses, fungi and rickettsia do not respond to the action of penicillin. This is due to the fact that these microorganisms are capable of producing a specific enzyme - penicillinase, which destroys the lactam ring in the penicillin molecule, as a result of which they lose their antimicrobial effect.

Application

Treatment for large cattle, sheep, goats, pigs, horses, rabbits, fur-bearing animals and dogs, chickens, ducks, turkeys necrobacteriosis, pasteurellosis, pneumonia, mastitis, wound infection and infections urinary tract, septicemia, phlegmon, as well as actinomycosis, emphysematous carbuncle, streptococcal infection; wash, catarrhal and lobar pneumonia, influenza, stachybotriotoxicosis of horses; streptococcosis, staphylococcosis, infectious stomatitis and rhinitis, plague of fur-bearing animals and dogs; erysipelas of pigs and spirochetosis of poultry.

Dosage

Solutions of the sodium salt of benzylpenicillin are prepared in sterile distilled water or in a 0.5% solution of novocaine, which prolongs the action of benzylpenicillin, or in an isotonic solution of sodium chloride and administered intramuscularly. To maintain the required constant high concentration in the blood, penicillin is administered 4-6 times a day in the following doses:

Kind of animals and birds	Single intramuscular dose, U/kg body weight
	Adults	Young animals
cattle
sheep, goats
fur animals and dogs
chickens, ducks, turkeys

The course of treatment is at least 4-7 days, in severe forms of the disease 7-10 days or more. A solution of benzylpenicillin sodium salt can be administered intravenously (in severe septic conditions). With this method, the dose of antibiotic is 2 times less than that recommended for intramuscular administration. It is also used subcutaneously and as a powder on wound surfaces. If necessary, you can use an aerosol.

Contraindications

Prohibited for use in animals with hypersensitivity to the drug.

Warning

Slaughter of animals for meat is allowed on the 3rd day, consumption of milk for food on the 2nd day after the last administration of the drug. By the specified date, meat and milk are fed to non-productive animals or disposed of (depending on the veterinarian’s conclusion).

Release form

Glass bottles of 500, 1000, 1500 thousand units.

Storage

List B. Dry, dark place at a temperature from +5°C to +20°C.

Most often, antibiotics are administered intramuscularly. Antibiotics for injection are produced in the form of crystalline powder in special bottles. Before use, it is dissolved in a sterile isotonic solution of sodium chloride (saline solution 0.9% sodium chloride), water for injection or 0.25%, 0.5% solution of novocaine, 2% solution of lidocaine.

The most popular is antibiotic PENICILLIN(benzylpenicillin sodium or potassium salt). It is available in bottles of 250,000, 500,000, 1,000,000 units. Dosed in action units.

It is better to dissolve penicillin in a 0.25% or 0.5% solution of novocaine, because it is better retained in the body. In case of individual intolerance to novocaine, use saline solution or water for injection.

There is a rule: For 100 thousand units (0.1 g) of penicillin (benzylpenicillin sodium salt), 1 ml of solvent is taken.

Thus, if the bottle contains 1,000,000 units, then you need to take 10 ml of novocaine.

X =------------------= 10 ml solvent

The penicillin solution cannot be heated, because under the influence of high temperature it is destroyed. Penicillin can be stored in diluted form for no more than a day. Penicillin should be kept in a cool and dark place. Iodine also destroys penicillin, so iodine tinctures are not used to treat the rubber stopper of the bottle and the skin at the puncture site.

Penicillin is administered 4-6 times a day every 4 hours. If the contents of the bottle are intended for one patient, penicillin is diluted randomly with 2-3 ml of novocaine or water for injection (if there is an allergy).

STREPTOMYCIN can be dosed both in grams and in units (units of action). Vials of streptomycin are available in 1.0 g, 0.5 g, 0.25 g. Therefore, in order to dilute it correctly, you need to know TWO RULES:

1.0 gr. corresponds to 1,000,000 units.

0.5 g -"-"- 500000 units.

0.25 g -"-"- 250000 units.

250,000 units of streptomycin are diluted with 1 ml of 0.5% novocaine

500,000 units - 2 ml of 0.5% novocaine

1,000,000 units - 4 ml of 0.5% novocaine _

BICILLIN - antibiotic of prolonged (extended) action. Bicilin - 1, Bicilin - 3, Bicilin - 5. It is produced in bottles of 300,000 units, 600,000 units, 1,200,000 units, 1,500,000 units.

The solvent used is isotonic sodium chloride solution, water for injection. It is necessary to REMEMBER that 300,000 units take 2.5 ml of diluent

600000 units -"-"- 5 ml

1200000 IU-"-"- 10 ml

1500000 IU-"-"- 10 ml

Rules for performing bicillin injections:

1. The injection is performed as quickly as possible, because the suspension crystallizes. The injection needle should have a wide bore. Air from the syringe should only be released through the needle cone.

2. The patient must be fully prepared for the injection. We dilute carefully in the presence of the patient. When diluting the suspension, there should be no foaming.

3. The suspension is quickly drawn into the syringe.

4. The drug is administered only IM, deep into the muscle , It is better to use the 2-step method in the thigh: before insertion, after puncturing the skin, pull the plunger towards you and make sure that there is no blood in the syringe. Add the suspension.

5. Apply a heating pad to the injection site.
