Drains are placed in wounds to evacuate fluid that would otherwise accumulate due to dead space, inflammation, infection, and/or necrosis. Fluid accumulation in a wound can be detrimental because it:

  • Acts as a medium for bacteria
  • Separates tissues that need to heal together
  • Creates pressure that can cause pain and decrease local blood flow.1

CONSIDERATIONS

Drains do not replace debridement and lavage, and wounds that contain bacteria, foreign material, or tissues that might necrose are preferably left open and bandaged with moisture retentive dressings rather than being prematurely closed over a drain.2

Drains should be used sparingly in neoplastic sites due to the potential of tumor cell tracking along the drain. If a drain must be placed after tumor resection, it should be exited close to the wound edge at a site that could be readily resected or radiated if clean margins were not obtained.1,3

JACKSON-PRATT DRAINS

A Jackson-Pratt drain (JPD) is an active suction drain consisting of a fenestrated, flexible, silicone tube connected by a nonfenestrated tube to a compressible reservoir (called a grenade due to its shape) (Figure 1).

The fenestrated end of a JPD (which is placed in the wound bed) is available in a range of widths and may be flat or round. The fenestrations direct fluid into the nonfenestrated portion of the tubing and then into the grenade. The grenade has a one-way valve to prevent retrograde movement of the fluid. Common grenade sizes range from 100 mL to 400 mL.

Benefits of a closed, active suction drain, such as the JPD, over an open, passive drain, such as the Penrose drain, are many (Table) and include the:

  • Use of suction to actively remove exudate and close down dead space
  • Flexibility of being able to exit the active drain in a nondependent location
  • Collection of exudate in a closed system.
  • In addition, a closed system:
  • Lowers the risk for ascending infection6,7
  • Is cleaner to manage
  • Protects skin
  • Allows easy quantitative and qualitative assessment of exudate.

Troubleshooting

If the JPD will not hold suction, make sure:

  • The grenade is securely attached to the tube
  • The evacuation port is closed
  • There are no holes in the external tubing (eg, from patient chewing or from the needle used for the purse-string suture).

If the incision itself is not airtight, add sutures or staples or cover it with a dressing +/- sterile ointment. The incision should become more airtight as the fibrin clot in the wound edge becomes more organized.

A JPD can become obstructed with blood clots, fibrin, pus, or tissue, although due to the large number of holes, this is unusual. If there is an obstruction:

  • Make sure the bulldog clamp is open and the tube is not kinked.
  • Empty and then reactivate the grenade to maximize the amount of suction and determine if the improved suction dislodges the obstruction.

A tube that remains obstructed may be flushed with sterile saline using sterile technique. This should only be done after carefully considering whether keeping the drain functional is more important than the potential risk for introducing contaminants into the wound when flushing. Drains that are not functioning should be removed, as their presence may increase the amount of wound fluid and risk for infection.4,5

STEP BY STEP: PLACING THE DRAIN

As with any drain placement, aseptic technique is essential when placing and handling a JPD.8 Disposable or sterile gloves should be worn when handling the drain and grenade, and when removing the drain.

Step 1. Choosing Drain Exit Site

After wound debridement and lavage, choose a drain exit site in healthy skin, where it is:

  • Easy to cover the exit site
  • Easy to manage the grenade
  • Comfortable for the patient.

For example, a good exit site for a wound over the caudolateral abdomen is a location where the JPD exits dorsally, which allows the clinician easy access to the tubing and grenade (rather than working under the dog or next to the hindlimb, if the drain exited ventrally or on the side, respectively) and allows the dog to lie in lateral or sternal recumbency without lying on the drain or getting the exit site dirty.

Do not exit the tube through the incision itself, as this may:

  • Prevent an airtight seal
  • Interfere with healing
  • Increase the risk for wound infection.

Step 2. Placing the Drain

To place the drain, tunnel a pair of forceps from inside the wound to the planned exit site (A). Push the forceps tips against the deep surface of the skin and incise the skin immediately over the tips with a scalpel blade, making a hole no larger than the JPD tube. (Some JPDs have a trocar; push the trocar through the skin from the wound-side out, then cut the trocar off).

Open the forceps enough to interlock with a second pair of forceps (B) and pull the latter into the wound (C). Grasp the nonfenestrated end of the JPD tube with the second forceps and pull it from inside to outside the wound (D). Protect the fenestrated end of the drain during this process so it does not rub along the skin where it might pick up contaminants (E).

Place the JPD’s fenestrated end into the most dependent part of the wound where fluid will accumulate (F). The entire fenestrated area must be underneath the skin and, therefore, inside the wound when it is closed; the end can be cut shorter as needed.

Step 3. Closing the Wound

Place a purse-string suture (eg, 2-0 nylon) in the skin around the exit site to help hold the tube and create a seal. It is important to:

  • Locate the knot where the tube naturally lies against the body to avoid kinking when the tube is pulled in the direction of the knot (A)
  • Leave both ends of the purse-string suture equally long to use them for a fingertrap pattern on the tube (B).
  • Additional security can be achieved by placing a butterfly of surgical tape on the tube and stapling it to the skin (see Step 7 Figure).

Close the wound in multiple layers as appropriate. Do not catch the drain in the sutures.

t1611c07fig03

Step 4. Placing the Grenade

Trim the external tubing to a length that allows convenient manipulation of the grenade; then place a bulldog clamp on the tube, which allows it to be readily closed off if the grenade is dislodged. Securely attach the nonfenestrated end of the tube to the port with the one-way valve on the grenade (A).

To activate the grenade, compress it to push air out the evacuation port, close the evacuation port with the built-in plug or an IV catheter adapter cap (PRN), and release the compression (B). As the grenade tries to resume its original shape, negative pressure is exerted through the tubing and into the wound. Higher suction can be generated by rolling up the grenade from its apex to base on a table top to push out the air rather than squeezing it by hand.10

Residual fluid from lavage, and/or residual air after surgery, may cause the grenade to fill up right away. If this occurs, simply empty the grenade (see Step 6) and repeat the activation process until negative pressure is achieved.

t1611c07fig04

Step 5. Protecting the Drain

Cover the JPD’s exit site with an adhesive dressing to prevent bacteria entry around the tube. Put a shirt, stockinette, or bandage on the patient to protect the external tubing and grenade from being stepped on, caught in a kennel door, or soiled. If the patient can reach the drain with its mouth, the patient should wear an Elizabethan collar when not under direct observation.

t1611c07fig05

Step 6. Maintaining the Drain

Monitor the quantity and quality of fluid in the grenade, starting with checks every 1 to 2 hours to get a sense of the production rate for the wound; then every 4 to 6 hours as appropriate. Empty and reactivate the grenade at least once a day or whenever it is half full (whichever is shorter), since the strength of suction decreases as the grenade fills.11

To empty the grenade:

  • Close the bulldog clamp
  • Clean the secondary port with alcohol
  • Open and attach a syringe to the secondary port
  • Evacuate the grenade with the syringe.

Alternatively, if a PRN was placed in the secondary port, clean the PRN with alcohol and aspirate the fluid with a needle and syringe (as seen in the Figure).

Reactivate the drain as described in Step 4. Daily cytology can be performed on a sample of fluid to monitor the state of inflammation or infection.

t1611c07fig06

Step 7. Removing the Drain

It is difficult to establish rules on when to remove a drain because fluid production varies with the wound’s etiology, dimensions, location, and degree of inflammation or infection.1,10 Because the drain itself stimulates some fluid production, the amount of drainage is not expected to reach zero.

When a wound is healing, the:

  • Fluid becomes serosanguineous
  • Volume decreases to a steady state
  • Cytology shows resolving inflammation and improved cell health.

All these signs indicate that it is time to remove the drain.

The risk for seroma formation was higher in human and canine patients that were still producing relatively large amounts of wound fluid when the JPD was removed compared with patients in which the wound fluid production had steadily decreased.8,9

To remove the drain:

  • Close the bulldog clamp on the tube
  • Cut the purse-string suture
  • Apply steady, gentle traction to remove the JPD (shown in the Figure)
  • Cover the hole in the skin with a sterile dressing; allow it to heal by second intention.

INPATIENT OR OUTPATIENT MANAGEMENT

There are several important reasons to keep patients with a JPD in the hospital, which is my preference:

  • Drains need to be handled with aseptic technique.1,8
  • Patients must be closely supervised to prevent damage or dislodgment of the drain.
  • Fluid quantity and quality need to be observed multiple times a day to assess the healing process, recognize problems with drain function, and determine when the drain can be removed.

If a patient is sent home with a JPD, I advise clinicians to:

  • Spend time training the client in aseptic drain management (such as wearing gloves), which includes watching the client empty and reactivate the drain
  • Check the patient and drain daily.

Discomfort with Drains?

Human patients report:

  • Discomfort when the reservoir is activated if the wound has little fluid or dead space, likely because the suction is directly against the healing tissues.
  • More pain with abrupt removal of closed suction drains than during removal over a 15-second interval, with the most discomfort occurring as the fenestrated portion of the drain emerged.2

In my experience, JPDs are well tolerated by dogs, and removal can be done in a fully awake patient. Just as for vaccine administration, distracting the patient with petting and talking is typically all that is needed.
