SUBCUTANEOUS FLUID ADMINISTRATION


Administration of supplemental fluids can benefit cats with a variety of medical conditions. Most commonly,
this is recommended for cats with kidney disease. We recommend that you learn this technique for your cat.
Don’t be alarmed - it is normal to feel reluctance about this. Giving injections is outside the comfort zone for
most everyone outside the medical professions. However, fluid administration is not nearly as difficult as it
sounds. The benefits provided to your cat will make it well worth your time to learn this simple technique.

What equipment is involved?

The equipment consists of a bag of IV fluids, an IV drip set, and a needle. The IV drip set is simply a tube that
connects the fluid bag to the needle. You will eventually become comfortable with the steps involved.

1.        Remove the outer, protective bag from the inner IV bag.

2.        Remove the IV set from its packaging.

3.        The top end of the IV set has a large, pointed end with a protective cap. Remove this cap, but do not
allow it to become contaminated. IT SHOULD NOT TOUCH ANYTHING.

4.        Pull the protective covering from the exit port on the bottom end of the IV bag. This will expose a hole
that will accept the pointed end of the IV set.

5.        Push the pointed end of the IV set into the open hole of the IV bag. It must be seated firmly to prevent
leaks.

6.        Remove the protective cap from the lower end of the IV set, but do not discard it. Do not allow it to
become contaminated. IT SHOULD NOT TOUCH ANYTHING.

7.        Close the lock in the middle of the IV tubing by moving the roller. (The lock on a new IV set is often
already in the open position.)

8.        Gently squeeze and release the bulb at the top of the drip set until the bulb chamber is about half full
with fluid.

9.        Open the lock (roller) on the tubing and then hold or suspend the IV bag; fluid should flow freely.

10.        Be sure that all air bubbles run out of the tubing.

11.        Close the lock on the IV line by rolling the roller downward.

12.        Remove the protective cap on the lower end of the IV set.

13.        Break the protective covering around the needle so that the open end (not the sharp end) is
exposed. Do not allow it to become contaminated by allowing it to touch ANYTHING.

14.        Remove the protective cap from the lower end of the IV set, and place the open end of the needle on
it. Seat it firmly.

How is the needle inserted?

Insert the needle just under the skin in one of several locations that have unusually loose skin. These include:

•        At the level of the shoulder blades, just to the right and to the left of midline.

•        At the level of the back legs, just to the right and to the left of midline.

What is the correct technique?

1.        Choose a location where you will treat your cat. This may be on a table, countertop, or on your lap.

2.        Hang the IV bag about 3 feet (1 meter) above the level of your cat's head.

3.        Place your cat in the treatment location. Be sure both of you are in a position that will be comfortable
for about 10-15 minutes. The end of the IV set should easily reach your cat.

4.        Pick up a roll of loose skin in one of the above locations.

5.        Lay the point of the needle at the base of the roll of skin with the needle horizontal and pointing to the
cat's head. This assumes that the cat is in an upright or standing position.

6.        Advance the needle slightly forward while pulling the roll of skin backward. That should place the point
of the needle under the skin.

7.        Release the roll of skin. The point of the needle should remain under the skin.

8.        Grasp the IV set lock in one hand. Begin the flow of fluids by rolling the roller upward.

NOTE:  Some cats are more cooperative if they are placed in a box not much larger than the cat. A
cardboard cat carrier is often the correct size.

How much fluid should I give each time?

The instructions at the end of this handout tell how much to give for your specific situation. As a rule, the
average sized cat should receive 100-150 ml of fluids at one time. If you are using two spots, you should give
half of that amount in each location.

When you have given the prescribed amount, complete the following steps:

1.        Stop the flow of fluids by rolling the roller in the IV set lock downward firmly. If you do not close it well
and the bag is left hanging, fluid will drip out.

2.        Remove the needle from the skin and replace its protective cap.

3.        PLACE A NEW, STERILE NEEDLE ON THE DRIP SET AS SOON AS YOU ARE THROUGH. This keeps
bacteria that were picked up on the old needle from migrating into the fluids. If you wish, you may return it to
our hospital for proper disposal.

4.        Store the equipment in a safe place until the next fluid administration.

What other tips do I need to know?

It is not necessary to "sterilize" the skin with alcohol before inserting the needle. In reality, wiping a little
alcohol on the skin does not really sterilize it, and the odor and feel of alcohol may aggravate your cat. Many
cats will taste the alcohol and begin to drool profusely.

Most cats tolerate fluid administration quite well. However, if the fluids are unusually cold or hot, they may be
uncomfortable. Ideally, they should be stored at about body temperature. However, as long as they are at
room temperature most cats are fine. Do not refrigerate them.

As the fluids are running, a lump will form under the skin. Do not be alarmed; this is the pocket of fluid that will
be absorbed over several hours. If absorption is slow, gravity may cause the fluids to migrate downward.
They could move under the skin of the front or rear legs. However, if this happens, they will still be absorbed.

There is no problem if a few bubbles of air are injected under the skin. If quite a bit of air gets under the skin,
you may feel a crackling sound when you push on the skin, and your cat may experience mild discomfort for a
couple of hours, but no real harm will occur. The body will eventually absorb the air.

What to do if the fluids stop running

This often happens when the end of the needle moves against the skin or the underlying tissue. Do not
remove the needle; rather, gently reposition it until the fluids begin to flow again. Experiment with the needle's
position until the fluids flow freely. Twisting the needle will change the position of the bevel. This may be all
that is needed.

What to do if the fluid runs slowly on subsequent treatments

When you are finished giving fluids, you should close the lock firmly. However, closing the lock firmly may
crush the tubing so that fluid will not flow well on subsequent use. If this happens, move the lock to another
place on the IV tubing, and open the crushed area of the tube by pinching it with your fingers.

What to do if the fluids become cloudy in appearance

If any cloudiness or discoloration occurs, do not use the bag. It usually means that the fluids have become
contaminated with bacteria. If you administer these fluids to your cat, a serious infection may occur under the
skin.
