Dropper for a dog: types, rules for the procedure

Unfortunately, most of us have had to deal with pet disease. The animal will not say what and where it hurts, so it often comes to the veterinarian already in critical condition. The fastest and most effective way to administer the required medication to a patient is infusion therapy. Therefore, the doctor often uses droppers to quickly help the animal and alleviate the symptoms of the disease.

Treatment with drips is often used to administer antibiotics or saline. Usually, treatment is scheduled for several days, that is, one procedure is not enough. If it is not possible to visit the veterinarian every day for the procedure, then they put a dropper at home.

How to put or remove a catheter for a dog or cat at home?

If they are not given urgent help, they will die. And we, ordinary people, lack the skills and abilities to provide the necessary assistance. Many diseases require serious attention, which makes it necessary to make droppers, and it is not possible to visit a doctor.

But if a dog or cat is injected daily, then there will be no living space left on them. Therefore, an intravenous catheter becomes a great help, with the help of which you can make both a dropper and an injection at any time.

Main conditions

Before proceeding with the independent setting of droppers for a dog, you need to see how this manipulation is carried out by a veterinarian. If the animal is to undergo a course of droppers, the doctor will first put him on a flexula. This is a special plastic catheter that is placed in a vein for several days and avoids daily venipuncture.

After that, the owner will be able to put droppers on their own, because. reliable venous access is already in place. The main thing is to get acquainted with the basic rules for carrying out this manipulation.

  • The drug solution, the introduction of which is supposed to be slightly warm or have a temperature close to room temperature. An intravenous infusion of a cold drug often causes the animal to shiver or lower its general temperature.
  • Infusion should be carried out at a slow pace, with a frequency of approximately 20-30 drops per minute. Jet administration of the drug can lead to convulsions, nausea, and cause an increase in pressure.
  • Before connecting a drip, make sure that the intravenous system is completely filled with solution and there are no traces of air in it. If air enters a dog's vein, a gas embolism can occur, often resulting in the death of the animal.
  • You should prepare for the fact that while the dog is being injected with medicine, you must constantly be near the animal, making sure that it does not damage the dropper and does not remove it.
  • Before starting the preparation of the system and the manipulation itself, it is necessary to thoroughly wash your hands with soap and then treat them with an antiseptic.
  • If possible, it is best to wear sterile medical gloves.

When should an intravenous catheter be used in dogs and cats?

  • Emergency conditions, resuscitation, operations that require quick access to the bloodstream (for example, if you need to urgently and quickly administer drugs).
  • Hospitalization of an animal with convulsions.
  • Assigned parenteral nutrition.
  • Hyperhydration or hydration of the body.
  • Blood transfusion (whole blood, red blood cells).
  • Multiple or continuous administration of drugs intravenously.
  • The need for a quick and accurate administration of the drug in an effective concentration (especially when the drug can change its properties with oral administration).

Possible problems

If the drug is not filled with drops, then you need to suspect one of the causes below.

  • A microthromb was formed in the catheter, which violates its cros s-country ability. It is not difficult to solve this problem – you just need to rinse the flexus. For this purpose, you need to take a sterile syringe with a volume of 5 ml. A needle is put on it, with which a sterile solution is typed from the bottle. Remember that only sterile solutions can be administered intravenously!

A dropper is removed from the catheter, and a syringe is inserted in its place, but without a needle. The solution should be slowly introduced into the vein, pressing on the piston of the syringe. After the washing is completed, remove the syringe and insert the dropper back.

  • If the medicine still does not drip, you need to pay attention to the position of the dog’s limb. If the paw is bent, the vein can be transmitted or the catheter rests somewhere on its wall.

Give the limbs of the animal a flat position and if necessary, fix it.

  • Also, the absence of drops may be due to the fact that the duct installed in the bottle with the solution is closed. Just open it.

If the medicine still does not drip, it is best to contact the veterinarian. Perhaps the intravenous catheter is damaged and requires replacement. You should not independently remove the catheter from the animal vein without instructions and recommendations from a veterinarian.

Of course, the ability to put a dropper of the dog is very useful. But still, let all pets will be healthy and delight their owners for many years.

Chen often in veterinary medicine with emergency and recovery therapy use intravenous injections: jet or drip.

Typically, these manipulations are performed by a veterinarian in the clinic or at home, since intravenous injections require more accuracy and caution than intramuscular and subcutaneous.

But sometimes there are times when the owner of the animal has to put a dropper himself.

This article will tell you how to do it right.

La intravenous injections will need ordinary needles, buckles or brownie needles (catheter for peripheral veins).

A veterinarian must be stopped by an intravenous catheter.

In Vienna, with proper use and hygiene, the catheter can be up to five to six days.

Raunulya is a thin plastic tube, which is located in the lumen of the vein and plastic port, which is fixed on the skin of the animal. The port closes with a screw cover. Brownun is attached with adhesive plasterer on the front or rear paw of the animal, in the area of the subcutaneous

Different physiological solutions are used in intravenous injections: saline (NACL 0. 9%), Glucose 5%, Ringer's solution (in veterinary medicine Ringer-Logk), Disol, Trisol, Hartmann solution and others.

All of these drugs are available in various volumes, in glass bottles and plastic packaging.

It is desirable that the infused solution has a temperature of 30-35 degrees.

Do not be lazy in front of the dropper once again to CHECK THE DOSAGE of the prescribed medication from your veterinarian!

Droppers also require an infusion set. Systems can

vary in appearance, but any dropper always contains the following components:

1. Suction needle 2. Built-in air duct or air intake needle

3. Intake chamber with filter

4. Silicone tube (conductor)

6. Rubber valve with cannula

Photo 6. Infusion set.

How to prime the system

A tripod is used for fixation in veterinary clinics.

at home, it is convenient to use a plastic bag with handles for fixing.

the infusion system is released from the packaging, the dispenser wheel is moved to the extreme position, while making sure that the silicone tube is pinched.

Then, having removed the cap, the cork of the vial is pierced with a sampling needle. Attention – the needle must be TWISTED

If there is no built-in air duct, then an additional needle is inserted into the cork.

If it is, then make sure that the air inlet is open.

then one or two times pressing the walls of the intake chamber (photo 12), fill it with a solution to half. (photo 13)

then, slowly adjusting the dispenser wheel, gradually fill the silicone tube to the first drops from the cannula. (photo 14)

When the first drops appear, squeeze the tube again. (close).

IMPORTANT – at the initial stage of filling the conductor tube, the solution in the intake chamber must DROPP

This is necessary to prevent air bubbles from being drawn into the silicone tube.

Your system is primed.

Photo 13. Photo 14.

Now you need to prepare the catheter. To do this, remove the bandage (if the catheter was bandaged), unscrew the catheter cover counterclockwise (photo 15) and insert the system cannula into the catheter port. (photo 1 6-17)

Slowly moving the dispenser wheel, adjust the rate of injection of the solution.

IV Catheter Placement Errors in Veterinary Medicine

The average speed of the solution is one drop per second.

For each specific case, the rate of administration is selected individually. Check with your veterinarian.

How to end a drip infusion.

After you have instilled the entire required volume of the solution, the system is closed, the cannula is removed from the port and the catheter cap is screwed clockwise.

Open the lid of the catheter valve (the lid can have a different color – blue, yellow, pink, green), insert a syringe with the collected heparin solution and inject, piercing the rubber valve, 0. 1 – 0. 3 ml of the solution into the lumen of the catheter. This is necessary so that the blood does not coagulate in the catheter and does not form a blood clot.

The syringe is pulled out, the cap is closed. The catheter, if necessary, is bandaged.

Health to you and your animals!


When receiving appointments from your veterinarian, find out in detail which drugs, in what sequence and at what speed (!) will need to be administered along with the main dropper solution. Be sure to write this information down, don't rely on memory! If you have no experience at all, then the first few times, the dropper must be done in a veterinary clinic, under supervision. Do not hesitate to ask questions to the staff, because the life of your beloved pet depends on your mistakes.

At home, a dropper can be done both subcutaneously and intravenously. For intravenous administration, a catheter is placed on the dog's paw. The procedure for installing an intravenous catheter should only be done in a veterinary clinic!

An intravenous catheter needs proper maintenance and care. Before the next infusion, the outside of the catheter cannula must be treated with a disinfectant solution. The catheter should then be flushed. The fact is that in the intervals between droppers, the remnants of blood in the catheter coagulate and form a blood clot. Insert a syringe (not a needle!) into the cannula and try to suck the clot into the syringe. At the end of the dropper, to prevent the formation of a blood clot, it is necessary to fill the catheter with a mixture of heparin and saline from a syringe, thus creating a "heparin plug" that prevents blood from clotting inside the catheter. Heparin is mixed with saline in a ratio of 1 ml. heparin 40 ml. saline.

Prepare a place for the drip. Put a warm bedding, and under it a diaper or a piece of polyethylene. During the drip, the dog should not be supercooled, so consider in advance how you can cover it.

The vial with the solution should be as high as possible above the animal, in no case at the level of the catheter! Wrap the bottle with tape and make a loop to secure it in a vertical position. Hang the bottle, for example, on the wall, with the cap down.

Prepare: drugs, syringes, drip system, alcohol, cotton wool, sterile wipes, bandages, scissors and an ampoule cutter, a doctor's prescription.

Pre-fill the syringes as directed by the veterinarian, releasing air bubbles, and cover the needles with protective caps.

Wipe the bottle cap with alcohol and insert the drip system needle until it stops. Insert an air needle nearby and open its cap.

Squeeze the dropper several times so that the solution fills it one-third. Move the clamp wheel up to the stop, thus opening the flow of fluid into the system. Allow the solution to fill the system until all air bubbles are expelled.

It is unacceptable to administer intravenous fluid in the presence of air bubbles in the system.

Move the clamping wheel all the way down (close the solution supply). Now everything is ready. Lay the dog in the prepared place. Unbandage the paw and, after removing the stopper from the catheter, rinse it. Attach the drip system to the catheter, move the clamp wheel up and adjust the rate of injection of the solution in accordance with the doctor's prescription.

Inject drugs from a syringe with a needle into the rubber part of the system. Strictly follow the sequence, dosage, rate of administration recommended by your veterinarian.

Don't leave your dog unattended for a second! Talk to her gently, try your best to calm her down. As a rule, from the introduction of the solution, the dog quickly falls asleep.

If the animal becomes visibly nervous, this may indicate that the drip rate is too high. In this case, reduce the speed and give the dog a little rest.

At the end of the drip, close the clamp and disconnect the system. Fill the catheter with heparin and close it with a sterile stopper flushed with the same heparin. Bandage the paw tightly.

If the dropper does not drip, then perhaps the catheter bent inside the vein or failed. Try to find the position of the dog’s paw in which it will become possible to complete the procedure. Otherwise, replace the catheter in the clinic. To administer the drug from a syringe instead of a dropper is dangerous, since a faulty catheter could jump out of the vein and get under the skin.

Control the condition of the skin around the catheter and if you notice a swelling, stop the dropper.

Unfortunately, most of us have had to deal with pet disease. The animal will not say what and where it hurts, so it often comes to the veterinarian already in critical condition. The fastest and most effective way to administer the required medication to a patient is infusion therapy. Therefore, the doctor often uses droppers to quickly help the animal and alleviate the symptoms of the disease.

Drops treatment

It is often used to introduce antibiotics or physiological solution. Typically, treatment is signed for several days, that is, one procedure is not possible. If there is no way to visit the veterinarian every day for the procedure, then they put a dropper at home.

Criteria for choosing a vein and catheter for dogs and cats

Safen’s lateral vein is more accessible in dogs, while in cats it is easier to introduce a central catheter through the medial vein of Safen. Cateters introduced into the rear leg are more difficult to keep clean and are not recommended for patients with urinary incontinence or diarrhea.

With intravenous injections, the advantage remains with the peripheral veins. Vienna should be soft and elastic, without seals and nodes. It is better to administer drugs into large veins, in a straight area corresponding to the length of the catheter.

  • Vienna diameter (the diameter of the catheter should be less than the diameter of the vein).
  • The necessary speed of administration of the solution (the larger the size of the catheter, the higher the speed of the solution).
  • The potential time of the catheter in Vienna (no more than 3 days).

Types of Enlaying needles

When setting up a dropper, different games are used. They have a number of features. In the absence of skills at home, you can use not all types. In this matter, you need to figure out in detail.

Infusion disposable

Attach to the system. They differ in thickness and length. With subcutaneous introduction into the withers, an average long needle is used in thickness.

With intravenous infusion, which is considered more traumatic, a needle of medium length and minimum thickness is used.

The needle "butterfly"

A short, rather thin needle. It is introduced to people into small veins. Suitable for small pets. It has a special design: “wings” made of plastic are placed in front of the expander. With their help, the needle is conveniently fixed.

Intravenous catheter

This is a plastic tube intended for introduction to Vienna. The drug enters through the catheter, and then the gateway is covered with a cork.

It is worth knowing how many days you can use such a needle: it can remain in Vienna for up to six days, but only with proper care of the puncture site.

Whether all needles can be used independently

Not all needles are allowed to install a puppy and an adult dog on its own.

The introduction of the catheter should be done by an exclusively veterinarian. In the absence of experience, there is a risk of damage to the nerve endings and veins.

Preparation of dogs and cats for the production of a re – -chief catheter

  • Spread a clean diaper or sheet (ideal if you iron or break it with an iron).
  • Put and calm the pet.
  • Shave off the hair where you are going to put the drip.
  • Better if it is a paw. In any case, the place will be determined by the veterinarian.
  • The paw of the animal should be straightened so that the vein is not pinched. You can fix it (paw) with the help of a splint – a plank bandaged to the paw.
  • The puncture site is disinfected.

Drip system or – dropper

On the one hand, it is connected to a catheter in a vein, and on the other hand, it is inserted into a vial with a solution. At one end there is a wide plastic needle (with an air duct) 1

, a filter to trap dust and air bubbles, 2 – the dropper itself. At the other end of the tube there is an orange soft rubber knot 5 ending in a cannula 4 and a needle inserted into the vein. The needles are in special caps. On the tube there is a device 3 (clamp-regulator) for adjusting the rate of injection of the solution.

Rules for placing a peripheral catheter in dogs and cats

  • Placement of the catheter must begin with good lighting at the site of manipulation.
  • Next, the hands are thoroughly washed and dried.
  • Assemble a standard set for vein catheterization, while the set should contain several catheters of different diameters.
  • A tourniquet is applied 10-15 cm above the intended catheterization zone.
  • A vein is selected by palpation.
  • The catheter of the optimal size is selected, taking into account the size of the vein, the required rate of insertion, and the schedule of intravenous therapy.
  • Re-treat hands using an antiseptic, put on gloves.
  • The catheterization site is treated with a skin antiseptic for 30-60 seconds and allowed to dry.
  • Do not palpate the vein again! Having fixed the vein (it is pressed with a finger below the intended site of the catheter insertion).
  • Take the catheter of the selected diameter and remove the protective cover from it. If there is an additional plug on the case, the case is not thrown away, but held between the fingers of the free hand.
  • The catheter is inserted on the needle at an angle of 15 ° to the skin, observing the indicator chamber. When blood appears in it, the angle of inclination of the stylet needle is reduced and the needle is inserted into the vein by a few millimeters.
  • After fixing the stylet needle, slowly move the cannula from the needle into the vein to the end (the stylet needle is not completely removed from the catheter yet).
  • They take off the tourniquet.


If pathological processes are detected in an animal, it may be necessary to flush the bladder. The doctor will perform the procedure as follows:

  1. To relieve pain, the male needs sedation or general anesthesia. Clinicians use local aerosol analgesics (Lidocaine Asept (spray), Carmolis).
  2. Sterile lubricant is placed on the tip of the tube. Lubricated with a synthetic lubricant atraumatic tip is inserted into the lumen of the urethra. If the device cannot pass through the excretory canal, the veterinarian drains the animal's bladder by placing a needle outside and expelling the urine with a syringe.
  3. Once the first 2 cm of the catheter has entered the penile urethra, the non-dominant hand is used to retract the prepuce caudally to continue inserting the tube.
  4. With the regulation of water, electrolyte metabolism in an animal, parenteral fluid therapy is performed. The volume of infusion is 45-68 ml of crystalloids per kilogram of body weight for 30 minutes.
  5. Removal of obstructive materials is carried out using solutions that destroy plugs and mucus clots.
  6. Surgery may be required to remove stones from the organ to prevent the inflammation from recurring.
  7. When the device completely gets into the excretory canal, the liquid begins to be released from the tube. By color, consistency and smell, the clinician determines the state of the organ.
  8. Blood clots are eliminated using a novocaine solution.
  9. In cats with arrhythmias lif e-threatening with hyperkalemia, immediate treatment of sodium bicarbonate (stimulation of intracellular metabolism) or calcium gluconate (stabilization of the heart and threshold potential) is performed.

How to put a dropper of a dog and a cat

Owners of cats and dogs do not always have the opportunity to visit a veterinary clinic. And in some cases, veterinary assistance is needed urgently – for example, with poisoning. One of the procedures that in these cases resort to is the installation of a dropper of a pet. Preparations that are administered parenterally act bypassing the gastrointestinal tract, falling immediately into the blood. This ensures the rapid effect of the drug and the operational stabilization of the condition. Every owner of animals can learn how to put a dropper of a dog and a cat at home.

The structure of the system

The device for drip administration consists of several parts. Before starting it, you need to find out why all these details are intended.

Main part

This is a flexible tube. According to it, the drug gradually moves from the container to the needle and then enters the body.

The needles are sophisticated

There are only two of them in the set. Introduced into the capacity cover with the drug. One of them joins the tube, the second is equipped with an expand, provides an air flow into a container with a solution for infusion.


This is a box made of plastic, equipped with a runner or wheel. The dispenser is designed to regulate the speed of fluid movement.


A device made of transparent soft plastic. Inside the part there is a filter that prevents the penetration of air into the tube and blood.


The main purpose of this part of the structure is the introduction of additional drugs into the solution.

The part is a container or rubber pillow made of plastic.

A dropper device

The dropper consists of several parts.

Table 1. A dropper device, decoding of the designations.

The number in the photo The name of the component The purpose of the component
1 The needle that is introduced into Vienna The size depends on the type and age of the animal. For a kitten and a puppy, they take the thinnest, "insulin" needles
2 Capsucker A vacuum process occurs inside the container, under which the liquid is sucked inward
3 Adjusting device Allows you to regulate the rate of medication into the body
4 Plastic tubes Vessels through which the liquid moves to the needle

What you need to know when setting a dropper

When conducting the procedure, many points must be taken into account, otherwise irreparable harm will be done to the animal.

The temperature of the solution

The drug should not be hot or cold. The best option is the drug at room temperature.

What to do if the dog’s temperature is lowered

If the pet in the temperature is below the norm, part of the plastic pipe intended for transporting the solution must be placed in a container with water heated to +70 +80 ° C. Due to this, the drug passing through the system will warm up slightly. This contributes to the normalization of animal body temperature.

Solution infusion rate

Special attention deserves the speed with which the solution is introduced. Too fast ingestion of the drug into the body is unacceptable. No more than two drops should be poured per second.

With an increase in speed, the condition of the dog may deteriorate sharply, with the following:

  • gagging;
  • increased blood pressure;
  • shiver.

The consequences of airing a vein

It is unacceptable for air to enter the vein, otherwise a gas embolism will develop.

Constant monitoring of the pet during the procedure

During the procedure, the pet must be under constant supervision. The main task of the owner is to prevent the dog from running away and to identify negative changes in a timely manner.

Procedure for intravenous infusion

The room is equipped with a place for the procedure. This is what a table is for. The tabletop is covered with a blanket and a disposable diaper. Medicines are prepared as indicated in the instructions. At the injection site, the hair is cut off, if necessary, the area is shaved in order to clearly see the vein. The section between the elbow joint and the wrist is most suitable for this.

It is convenient to put a dropper on the forelimb in front of the elbow bend

Then prepare the drip system:

  • Open the package with the device.
  • Close the roller regulator by moving it to the lower position.
  • The fuse is removed from the needle inserted into the vial, the rubber stopper of the drug vial is pierced with a needle and pushed deep into the container to its full length.
  • The drug bottle is hung above the table on a suitable object on the wall (nail, hanger, etc.). It should be located much higher than the countertop.
  • Squeeze and release the needle reservoir until it is half filled with liquid.

The medicine container is placed upside down.

  • Release air by opening the roller clamp until the medicine flows from the drip system, block the system with a regulator.
  • Check if there are any air bubbles in the system. If they are found, the system is opened again to get rid of the air.
  • The limb above the elbow joint is clamped with a rubber tourniquet so that the vein fills with blood. Additionally, it is necessary to bend the limb at the elbow several times.
  • A needle is inserted into the vein, parallel to the limb. If the puncture is done correctly, then a little blood will appear in the tube, and no swelling will form on the paw when the drug is injected.
  • The needle is fixed on the paw with adhesive tape.

Important! The doctor needs to clarify how to prepare the medicine, in what dosage it should be administered. Violation of these rules can lead to the death of the animal.

After the required dose of medicine is poured in, the dropper is blocked, and then the needle is carefully removed. A cotton swab soaked in medical alcohol is applied at the puncture site.

Animal preparation

Optimal Infusion Sites

It is recommended to insert the needle into the wide veins located on the front paws of the pet.

Hair removal at the infusion site

The next step is to remove the hair between the elbow and wrist. It is shaved with a machine or cut with scissors.

Leg tourniquet

The limb is tightened before the puncture. The tourniquet is applied slightly above where the infusion will be performed.

Inserting a needle into a vein and fixing it with adhesive tape

The needle is disconnected from the dropper and carefully inserted into the vein parallel to the limb.

Actions perform slowly, very carefully. Pressing should be moderate. If everything was made without errors, a small amount of venous dark blood will be released from the expander.

Then the needle is fixed with adhesive plasters. Only after that is the tourniquet removed.

System connection

At the final stage, the needle is connected to the system. It remains only to control the condition of the animal and observe the place of puncture.

Installation of a catheter

An intravenous catheter (brownel) is installed when lon g-term treatment is necessary and a large amount of drugs is to be administered.

The installation of the catheter has several advantages:

  • constant access to Vienna with the possibility of rapid administration of the medicine in difficult cases;
  • It is not necessary to make a puncture of the blood vessel before each administration of the drug;
  • the presence of a catheter does not limit mobility;
  • saving time and effort;
  • lack of pain in the subsequent administration of drugs;
  • the possibility of blood selection for analysis;
  • The body of the body.

The installation of a catheter is best entrusted to an experienced veterinarian. The procedure requires skills in this area.

Catheter device

Braunuli design: 1 – valve, under which there is a hole for the administration of drugs (sometimes different colors);2 – part of the stylet, which is extracted after the catheter;3 – a screwy cover that blocked the entrance to the blood vessel;4 – Kanyulya to which a system or syringe without a needle is connected

To install the catheter, the following materials will be additionally required:

  • clamp;
  • a ra g-based adhesive plaster;
  • small sharp scissors (manicure);
  • bandage or rubber tourniquet;
  • Shaver.

Choose catheters by number, depending on the size of the animal.

Colling color and catheter size

The introduction of a catheter

Before installing the front limb of the animal in the area of the elbow joint and slightly lower with small scissors, the wool is cut and shaved with a machine in order to better see the subcutaneous vein.

The device is introduced into the subcutaneous vein. This place is considered the most convenient. There, the device lasts the longest and does not cause inconvenience to the pet.

The catheter is introduced in this order:

  1. Above the ulnar bend using a bandage or burn and clip, a limb for the blood-filling of the vein is pulled. This must be done with moderate force so as not to damage the blood vessels.
  2. With the help of small sharp scissors in the middle of the forearm, they make a small incision on the skin to enter the needle.
  3. In parallel of the limbs, a catheter is introduced. The tool is administered at an angle of about 15 ° to the stop until blood appears in the indicator chamber.
  4. The catheter is removed from the stylet, but not in the reverse order, since then the device will be installed incorrectly.
  5. Try to introduce a saline. If the catheter is installed correctly, then there will be no swelling, swelling on the paw.
  6. The device is fixed on the paw with a narrow adhesive plastry. During fixation, it is necessary to monitor the strength of the tension of the adhesive plaster – it should not be unnecessary so as not to break the bloodstream in the limbs and not cause withering away of the tissues.
  7. The catheter is washed to avoid the formation of blood clots.

Video – installation of a catheter

How the medicine is administered through the catheter

Through Brownun, drugs are poured in this order:

  1. The required amount of solution or drug is collected in a syringe or system.
  2. Drinking their paw.
  3. They unscrew the white cap, holding the device itself, in the direction counterclockwise.
  4. Open a colored valve.
  5. Connect a syringe with saline, press on the piston so that the liquid flows from another hole and the device is cleaned.
  6. Connect the syringe to the hole where the white container cap is, and inject the solution. If the piston moves without difficulty, you can connect the system and inject the drug.

It looks like a catheter connected to a dropper

Attention! If during preparation it turned out that the clot clogged the passage, it is necessary to rinse the device several times with saline through the hole under the colored valve.

After the end of the procedure, a syringe with saline or heparin is connected to the hole under the colored valve and 1 ml of liquid is injected. This is necessary to remove the blood clot.

Catheter Care

If the catheter is not properly cared for, then an infection can enter the body through it. Therefore, it is necessary to follow the rules of hygiene that will not allow the deterioration of the animal's condition.

  • Plugs must be sterile. Do not allow the use of plugs, on the surface of which there may be traces of infection.
  • After the introduction of the drug, as well as in the intervals between doses, the catheter should be thoroughly washed with saline.
  • The bandage fixing the catheter must also be clean. It is changed as it gets dirty.

Catheter under a bandage bandage on a dog's paw

Attention! The place of catheterization is recommended to be changed every 2-3 days.

How to remove the catheter yourself?

If a catheter is installed, it is necessary to carefully monitor the condition of the pet. In some cases, the device will have to be removed prematurely or without the participation of a doctor. The reason for this is damage, obstruction, leakage of the catheter, pain in the animal or swelling of the limb into which the drug is taken intravenously. Brownule must also be removed if more than 5 days have passed since the installation.

Swelling on the paw – a reason to see a doctor

They operate in this order:

  1. Cut the adhesive tape that secures the device.
  2. Carefully remove the adhesive tape from the pet's skin, trying to separate it from the fur (it is convenient to use nail scissors for this).
  3. Smoothly, but as quickly as possible, remove the device from the vein.
  4. A bandage moistened with alcohol, furacilin solution or hydrogen peroxide is applied to the puncture site.
  5. Bandage the limb and leave the bandage for an hour.

Attention! Pets do not always tolerate medical procedures, even painless ones such as catheter removal, and sometimes try to run away. To prevent this from happening, it is better to carry out manipulations with an assistant who will hold the dog or cat.

After removing the brownie, sometimes undesirable consequences appear. The paw may develop swelling, redness, or blueness. The pet begins to limp or bends its paw, whines, tries to pull it out when they feel the place where the catheter used to be. Then you can not do without a visit to the doctor.

After removing the catheter, a bandage is applied to the paw.

If the owner of a cat or dog knows in advance that he will have to remove the catheter on his own, then the veterinarian needs to ask how to do this, how to treat the wound and how to care for it later.

What should alert you after removing the catheter:

  1. The paw is very swollen, the color of the skin has changed (if it can be seen depending on the breed).
  2. Soreness appeared, the dog cannot use the limb normally – it limps or tightens its paw when walking.
  3. The general condition of the animal has changed: temperatures above the norm, refusal to feed, depression.

In most cases, everything goes without complications, but if the above symptoms appear and they do not go away within a day, then it is better to consult a doctor.

In principle, nothing complicated. Remove the bandage around the catheter, moisten a cotton swab with a disinfectant solution, such as chlorhexidine, and apply on top of where the needle exits, and then quickly pull the end of the catheter. Hold the cotton wool for some time pressed to the wound.

Subcutaneous infusion

Droppers with saline and some other drugs are administered subcutaneously to dogs and cats. This is also called subcutaneous infusion. The safest area for this is the withers.

The introduction of the drug is carried out in the following order:

  1. The cat or dog is fixed in such a way as to gain access to the withers or inguinal fold.
  2. Bring the dropper into working condition, connect it to the vial with the drug.
  3. Hand form a triangular fold on the skin in the selected area.
  4. The dropper needle is inserted into the base of the formed fold.
  5. Connect the drip.
  6. Open the system.
  7. After the introduction of the required amount of the drug, the system is blocked.
  8. Carefully remove the needle.
  9. Press down on the injection site so that the medicine does not leak out.

Video – Subcutaneous drip

The rate of dripping subcutaneously can be maximum, since in this case the solution is absorbed very slowly.

Attention! The amount of the drug is injected subcutaneously, not exceeding 20 ml per 1 kg of animal body weight per day. However, with a strong degree of dehydration, the dose may be higher – 40-50 ml / kg.

In the place where the drug enters, a subcutaneous bubble is formed. This is normal, as fluid enters the subcutaneous tissue. It will disappear very quickly.

Thus, the following solutions are introduced:

  • glucose (5%) (if there are no contraindications in the form of chronic diseases, in particular diabetes mellitus, behavioral disorders, seizures);
  • Ringer's solution, Ringer's – Locke;
  • saline solution (drip heated to a temperature of 40-45 ° C).

The disadvantage of this method is that other drugs cannot be administered by this method. In addition, drugs act more slowly in this case.

When administering the drug subcutaneously, beginners make mistakes that prevent the drug from entering the body. In the first case, the needle is injected intradermally, in the second case, a through puncture is made, and the solution is poured into the external environment.
