How much should a Hemovac drain?

You have been discharged with a Hemovac drainage tube. The tube was placed in your incision to remove fluid and is attached to a drain or collection device. It will help healing and reduce the risk of infection. Expect to see fluid and blood in the drain. You may also feel some burning and pulling from the stitch that holds the tube in place. Your drain will be removed when the fluid leaking from it is less than 2 tablespoons each day. There is a bandage at the site where the tube is placed. This is to protect the open area from infection. Your stitches will be taken out 7 to 14 days after surgery. Here's what you need to do to care for your Hemovac drainage tube.

General guidelines

  • Don’t sleep on the same side as the tube.
  • Secure the tube and bag inside your clothing. This will prevent the tube from being pulled out.
  • Take a sponge bath to avoid getting your bandage and tube site wet, unless your healthcare provider tells you otherwise.
  • Ask your provider when can you take a shower or bathe.
  • Ask your provider about the best way to keep the site dry when bathing or showering.


Empty the drain

Empty your drain at least twice a day. Empty it more often if needed.

  • Wash your hands. If someone is helping you, have that person wear clean, non-sterile gloves after washing their hands.
  • Lift the stopper. Don't touch the open port. The drain will expand.
  • Turn the drain upside down.
  • Drain the fluid into a measuring cup.
  • Record the amount of fluid each time you empty the drain. Total the amount daily. Share this information with your doctor on your next visit.
  • Place the empty drain on a hard surface and press down until it is flat.
  • Close the cork stopper device.
  • Wash your hands again.


Change the dressing

Change the dressing around the tube every day.

  • Wash your hands.
  • Remove the old bandage.
  • Wash your hands again.
  • Wet a cotton swab and clean around the incision and tube site. Use normal saline solution (salt and water).
  • Put a new bandage on the incision and tube site. Make the bandage large enough to cover the whole incision area.
  • Tape the bandage in place.
  • Wash your hands again.


Follow-up

Make a follow-up appointment, or as directed.


When to call your doctor

Call your doctor right away if you have any of the following:

  • Pain, swelling, or fluid around the tube
  • Redness or warmth around the incision or fluid draining from the incision
  • Nausea and vomiting
  • Fever above 100.4 °F (38 °C) or chills, or as advised
  • An incision that does not heal; stitches that become infected or loose
  • A tube that falls out
  • A foul smell from the incision site
  • Drainage that changes from light pink to dark red
  • An increase in the amount of drainage after an initial decrease

A Hemovac drain is placed under your skin during surgery. This drain removes any blood or other fluids that might build up in this area. You can go home with the drain still in place.

What to Expect at Home

Your nurse will tell you how often you need to empty the drain. You will also be shown how to empty and take care of your drain. The following instructions will help you at home. If you have questions, ask your health care provider.

Emptying Your Drain

Items you will need are:

  • A measuring cup
  • A pen and a piece of paper

To empty your drain:

  • Clean your hands well with soap and water or an alcohol-based cleanser.
  • Unpin the Hemovac drain from your clothes.
  • Remove the stopper or plug from the spout. The Hemovac container will expand. Do not let the stopper or the top of the spout touch anything. If it does, clean the stopper with alcohol.
  • Pour all of the liquid from the container into the measuring cup. You may need to turn the container over 2 or 3 times so that all the fluid comes out.
  • Place the container on a clean, flat surface. Press down on the container with one hand until it is flat.
  • With the other hand, put the stopper back into the spout.
  • Pin the Hemovac drain back onto your clothes.
  • Write down the date, time, and the amount of fluid you poured. Bring this information with you to your first follow-up visit after you are discharged from the hospital.
  • Pour the fluid into the toilet and flush.
  • Wash your hands again.

Changing Your Dressing

A dressing may be covering your drain. If not, keep the area around the drain clean with soapy water, when you are in the shower or during a sponge bath. Ask your nurse if you are allowed to shower with the drain in place.

Items you will need are:

  • Two pairs of clean, unused medical gloves
  • Five or six cotton swabs
  • Gauze pads
  • Clean soapy water
  • Plastic trash bag
  • Surgical tape
  • Waterproof pad or bath towel

To change the dressing:

  • Clean your hands with soap and water or an alcohol-based hand cleanser.
  • Put on clean medical gloves.
  • Loosen the tape carefully, and take off the old bandage. Throw the old bandage into a plastic trash bag.
  • Inspect your skin where the drainage tube comes out. Look for any new redness, swelling, bad odor, or pus.
  • Use a cotton swab dipped in the soapy water to clean the skin around the drain. Do this 3 or 4 times, using a new swab each time.
  • Take off the first pair of gloves and put them in the plastic trash bag. Put on the second pair.
  • Place a new bandage over the skin where the drainage tube comes out. Tape the bandage to your skin using surgical tape. Then tape the tubing to the bandages.
  • Throw all used supplies in the trash bag.
  • Wash your hands again.

When to Call the Doctor

Call your doctor if:

  • The stitches that hold the drain to your skin are coming loose or are missing.
  • The tube falls out.
  • Your temperature is 100.5°F (38.0°C) or higher.
  • Your skin is very red where the tube comes out (a small amount of redness is normal).
  • Fluid drains from the skin around the tube site.
  • There is more tenderness and swelling at the drain site.
  • The liquid is cloudy or has a bad odor.
  • The amount of liquid increases for more than 2 days in a row.
  • Fluid suddenly stops draining after there has been constant drainage.

What is normal drainage amount after surgery?

A mild amount of drainage from the incision is normal. If the drainage fluid is thin, watery, and pinkish red, there is likely nothing to be concerned about. However, there are instances in which you should be concerned about drainage from your incision.

What is the normal amount of drainage for at tube?

Drainage should NOT be more than 500 mL/day (notify MD if this happens)…the drainage will decrease as the patient recovers.

How much does a Hemovac drain hold?

Hemovac drains (see Figure 4.5) can hold up to 500 ml of drainage. A Jackson Pratt (JP) (see Figure 4.6) is used for wounds anticipated to have smaller amounts of drainage. Drains are often sutured to the skin to prevent accidental removal. The drain insertion site is covered with a sterile dressing.

How much drainage is normal after neck surgery?

Our study shows that, on average, the total volume of neck drainage in the morning after surgery is more than 25 ml in 79% of patients (median volume, 35 ml).
