Wound packing nursing: technique, materials, and clinical judgment

Wound packing is a distinct procedural skill performed on open, deep, or tunneling wounds to prevent premature surface closure, manage wound exudate, and maintain a moist wound environment that supports healing from the inside out. It is not the same as applying a dressing. Where a dressing covers the wound surface, packing fills the wound cavity — directly contacting the tissue at depth, supporting granulation tissue formation, and ensuring drainage can escape rather than pool.

Quick reference: when wound packing is indicated

• Deep cavity wounds with tissue loss extending below the skin surface
• Tunneling or undermined wounds with channels tracking beyond the visible wound edges
• Wounds healing by secondary intention (left open to close from the wound bed upward)
• Post-surgical wounds left open due to infection risk or contamination
• Wounds with moderate to heavy exudate that would pool without absorptive fill material
• Pilonidal sinus wounds after surgical excision

For the broader framework of wound assessment, wound healing phases, and dressing selection logic, see wound care nursing. This article focuses specifically on the technique, materials, and clinical decisions involved in wound packing.

What wound packing does

Wound packing serves three overlapping purposes:

Dead space elimination. Open wounds with tissue loss create a cavity beneath the surface. If that space is left empty, fluid accumulates, bacteria proliferate, and the wound closes over the pocket — trapping infection inside. Packing fills that space to allow healing from the base up.

Exudate management. The packing material absorbs wound drainage. Without it, drainage collects in the cavity, macerates the wound edges, and increases infection risk.

Moist wound environment. Modern wound management evidence supports moist (not wet, not dry) wound beds. Packing materials are selected and moistened to maintain that balance — supporting epithelialization and granulation without drowning the wound bed.

Wound packing is used for secondary intention healing. These wounds are intentionally left open and close gradually as granulation tissue fills the cavity from the base toward the surface. The nurse’s role is to support that process, track progress at every dressing change, and escalate when healing stalls or infection develops.

Packing materials: selection guide

Packing material selection depends on wound depth, exudate level, infection status, wound phase, and the patient’s pain tolerance. The most common options are:

Wet-to-dry dressings are no longer recommended. Wet-to-dry involved placing moist gauze in the wound, allowing it to dry, then mechanically debriding by tearing it out with the adherent eschar. This technique is non-selective — it removes healthy granulation tissue along with necrotic debris, causes significant pain, and disrupts the wound bed. Current evidence-based practice uses moist wound healing throughout. If mechanical debridement is indicated, it should be performed by a provider under order, not substituted with wet-to-dry packing.

Equipment

Gather all supplies before exposing the wound:

• Non-sterile gloves (for removing old packing)
• Sterile gloves (for applying new packing)
• Waterproof drape or pad
• Sterile irrigation syringe (35 mL with 19-gauge blunt tip or angiocatheter)
• Normal saline for irrigation and gauze moistening
• Sterile forceps or cotton-tipped applicators
• Packing material as ordered (gauze strips, alginate rope, or other specified material)
• Outer cover dressing (ABD pad, foam, or transparent film)
• Tape or securement device
• Measuring guide (ruler) for wound measurement
• Waste bag
• Eye protection and gown if irrigation is planned

Check the medication administration record and wound care orders before starting. Confirm the packing material type, solution, frequency, and any special instructions. Pre-medicate the patient for pain at least 30–60 minutes before the procedure if analgesics are ordered.

Step-by-step wound packing technique

Before you begin

1. Perform hand hygiene. Wash with soap and water or use an alcohol-based hand rub.
2. Introduce yourself and verify patient identity using two identifiers (name and date of birth, or name and MRN per facility policy).
3. Explain the procedure. Tell the patient what you are doing and what they will feel.
4. Assess pain and confirm pre-medication was given if ordered.
5. Position the patient so the wound is accessible and well-lit. Place the waterproof pad beneath the wound.
6. Apply non-sterile gloves and PPE (gown and eye protection if irrigation is planned).

Removing old packing

7. Gently remove the outer dressing and discard.
8. Count the pieces of packing being removed. Document the number — this ensures none is retained in the wound.
9. Remove the packing with sterile forceps. Pull slowly from the visible tail. If the packing adheres to the wound bed, moisten it with normal saline and wait 30–60 seconds before gently lifting. Never forcefully pull adherent packing — this tears granulation tissue.
10. Assess the wound before applying new packing: measure length, width, and depth; note tunneling location using the clock-face method (12 o’clock = toward the patient’s head); document exudate color, consistency, and amount; note tissue type visible (granulation, slough, eschar, epithelium).
11. Discard old packing and soiled gloves. Perform hand hygiene.

Irrigating the wound

12. Irrigate the wound before repacking if ordered or clinically indicated (visible debris, purulent drainage, prior infection).
13. Fill the 35 mL syringe with room-temperature normal saline.
14. Hold the syringe tip 1–2 cm from the wound at an angle that directs flow from the cleanest area toward the least clean, allowing debris to wash away.
15. Apply steady pressure — a 35 mL syringe with a 19-gauge blunt tip delivers approximately 8–15 psi, which is the clinically accepted pressure range for wound irrigation.
16. Irrigate until the return fluid runs clear. Document the volume used.
17. Tunneling precaution: Do not irrigate tunnels deeper than 15 cm, and do not irrigate tunnels where the endpoint is unknown or where fluid cannot be fully recovered. Irrigating a blind sinus can spread contamination to deeper tissue planes.
18. Pat dry the periwound skin but allow the wound bed to remain moist.

Packing the wound

19. Apply sterile gloves (or use a no-touch sterile technique with forceps throughout).
20. Prepare the packing material. If using plain gauze, moisten with normal saline and wring out so the gauze is damp but not dripping. It should hold moisture without leaving standing liquid in the wound. Iodoform gauze and alginate are pre-moistened or self-activating — follow manufacturer guidance.
21. Begin packing at the deepest point. Use sterile forceps or a cotton-tipped applicator to guide the packing material into the base of the wound first.
22. Fill the wound cavity loosely. The packing should contact all wound surfaces without being compressed. Overpacking creates pressure, impairs circulation to the wound base, and causes pain. Underpacking leaves dead space where fluid accumulates.
23. Work toward the surface. Fold, fan, or accordion the packing material as needed so it fills the cavity without gaps. In tunneled wounds, use a single continuous strip if possible — this makes removal simpler and reduces the risk of retained packing.
24. Leave a visible tail. The end of the packing must remain visible at the wound surface. A retained packing piece is a serious safety event; the visible tail is your confirmation that all packing can be removed at the next change.
25. Do not extend packing above the wound edges. Packing that overlaps onto periwound skin maceration the surrounding tissue and impairs epithelialization.
26. Count pieces placed and confirm the number matches what you documented removing. Document total pieces in (and compare to pieces out next time).
27. Apply the outer cover dressing per order — typically an ABD pad, foam, or similar absorptive secondary dressing secured with tape or a self-adhesive border. The cover dressing manages overflow drainage and protects the packing from contamination.

After the procedure

28. Assist the patient to a comfortable position.
29. Remove gloves and perform hand hygiene.
30. Document: wound measurements, tissue assessment, exudate description, packing material used, number of pieces placed and removed, irrigation volume, patient tolerance, and any changes from prior assessment.
31. Report concerns: Escalate to the provider for any of the following — new or worsening odor, increased warmth or erythema in the periwound skin, tracking infection (red streaks), new purulent drainage, fever, or wound that is not progressively decreasing in depth over successive assessments.

Packing vs. repacking: clinical tracking

Every packing change is an assessment opportunity. The wound should be decreasing in volume — getting shallower, narrower, and smaller — over successive changes. The amount of packing needed will decrease as the wound heals. Signs of progression:

• Less packing required to fill the cavity
• Pinkish-red, moist granulation tissue visible throughout the wound base
• Decreased exudate volume
• Wound margins showing epithelialization (light pink, new skin)

Signs of stalled or worsening healing that require escalation:

• No reduction in wound depth after multiple dressing changes
• Pale, gray, or friable granulation tissue (hypergranulation or poor perfusion)
• Increase in slough or eschar without debridement
• New malodor, green or brown drainage, or systemic signs of infection (fever, elevated WBC, elevated CRP)

Clinical significance

Wound packing is both a technical skill and a clinical assessment. Nurses performing wound packing generate the longitudinal data that drives wound management decisions:

• Wound measurements tracked over time determine whether the current treatment plan is working
• Exudate characteristics drive dressing material changes (heavy drainage → alginate; minimal drainage → switch away from saline gauze)
• Tunneling documentation guides surgical decisions (persistent or expanding tunnels may require operative intervention)
• Pain with packing that worsens rather than improves can signal infection or incorrect technique

Wound packing is also a patient education opportunity. Many patients continue wound packing at home after discharge. Clear teaching on technique, material handling, handwashing, what to watch for, and when to call the provider directly affects home healing outcomes. See wound care nursing for patient education content related to dressing changes.

Common mistakes

Packing too tightly. This is the most common error nursing students make. Packing should fill the space, not compress the wound base. Tightly packed gauze generates pressure against the wound edges, impairs blood supply to granulation tissue, and increases patient pain.

Using wet (not damp) gauze. Soaking the gauze creates excessive moisture at the wound base, macerates tissue, and increases infection risk. Wring out saline-moistened gauze until it is damp throughout but no liquid drips from it.

Allowing wet-to-dry by neglect. Even when wet-to-dry is not ordered, saline gauze that dries between changes becomes adhered to the wound bed. If the change frequency is too long for the wound’s exudate level, the gauze dries out. Adhere to the ordered change frequency, or escalate if the wound’s drainage level does not match the current schedule.

Packing above the wound surface. Mounding gauze above the wound level pushes outward on the periwound skin, causes maceration, and prevents epithelialization from advancing inward.

Extending gauze into unknown tunnels. Packing material placed into a sinus tract with an unknown endpoint may be impossible to fully retrieve. Always use a single continuous strip for tunneling wounds, leave a visible tail, and document the tunnel location and depth.

Forgetting to count. Failing to count packing pieces placed and removed creates the risk of retained packing — a foreign body reaction that causes localized abscess, pain, and failed healing.

NCLEX tips

• Wound packing is used for wounds healing by secondary intention — those left open to close from the base upward
• Packing should be loose, not tight — overpacking impairs healing
• Gauze should be damp, not wet — excess moisture macerates the wound bed
• Always remove packing gently; soak adherent material with normal saline before lifting
• Wet-to-dry dressings are not current evidence-based practice — they damage healthy granulation tissue
• Calcium alginate requires exudate to activate — it is not appropriate for dry wounds
• Iodoform gauze has antimicrobial properties but may impair healing with prolonged use and is contraindicated in iodine-sensitive patients
• Count pieces in and out at every dressing change — retained packing is a serious safety event
• A visible tail must be left at the wound surface at all times
• Tunneling wounds should be packed with a single continuous strip when possible
• Do not irrigate tunnels deeper than 15 cm or where the endpoint is unknown
• Wound volume should decrease over successive changes — stable or increasing volume requires escalation

NCLEX scenarios

Scenario 1

A nurse is repacking an abdominal wound healing by secondary intention. After removing the old packing, the nurse notices bright red granulation tissue at the wound base and the wound depth has decreased from 4 cm to 2.8 cm over five changes. What is the priority action?

Answer: Continue the current wound care plan — these findings indicate normal, progressive healing. The nurse should document the assessment findings and continue packing as ordered, adjusting the amount of packing used to match the reduced cavity.

Scenario 2

A nurse prepares to pack a tunneling wound. The order specifies “saline-moistened gauze.” After moistening the gauze, the nurse notices it is saturated and liquid drips from it when held. What is the correct action before packing?

Answer: Wring out the gauze until it is damp but not dripping. Saturated gauze creates excessive moisture at the wound base, risks maceration, and can pool drainage rather than absorb it.

Scenario 3

The nurse removes four pieces of packing from a wound but the order indicates five pieces were placed at the last dressing change. What is the priority action?

Answer: Do not repack until the fifth piece is located. Assess the wound carefully — use forceps to examine the wound bed and tunnels. If the fifth piece cannot be located, notify the provider immediately. Retained packing is a safety event requiring documentation and escalation.

Scenario 4

A wound has been packed with calcium alginate rope for three days. On reassessment, the nurse notes the wound base appears dry, the alginate has not formed a gel, and wound depth is unchanged. What does this indicate?

Answer: The wound exudate level is likely insufficient to activate the alginate. Calcium alginate requires moderate-to-heavy drainage to form the absorbent gel. The nurse should notify the provider — the packing material may need to be changed to saline gauze or a hydrogel product more appropriate for low-exudate wounds.

Scenario 5

A post-operative patient is being discharged with instructions to continue wound packing at home. Which statement by the patient indicates understanding of the teaching?

A. “I will pack the wound as tightly as possible to close the space.” B. “I will soak the gauze completely before placing it in the wound.” C. “I will wash my hands before and after the dressing change.” D. “I will change the dressing every three days unless it becomes wet.”

Answer: C. Hand hygiene before and after wound care is essential to prevent introducing pathogens. A is incorrect — packing should be loose, not tight. B is incorrect — gauze should be damp, not saturated. D is incorrect — dressing change frequency is determined by the wound’s drainage level and provider order; waiting three days on a draining wound is inappropriate.
