A useful wound packing scenario changes more than the shape of the wound. It gives the learner a different access problem, decision, failure signal, or reassessment challenge.
This guide shows instructors how to build five progressive stationsโfrom a visible laceration cavity to a mixed scenarioโwithout making the exercise unnecessarily complicated.
Three Principles for Every Station
1. Change One Main Difficulty at a Time
Keep the gauze, flow system, and scoring method consistent while changing one variable: visibility, cavity shape, body position, an internal landmark, or the need to choose a method. If everything changes at once, the instructor cannot tell what caused failure.
2. Define the Success Signal Before the Attempt
Decide what the model must show when the learner succeeds. The signal might be cessation of simulated flow, continuous pressure through a handoff, recognition that packing is not the correct taught method, or detection of renewed leakage after movement.
3. Keep the Clinical Boundary Explicit
State what is simulated, which recognized course or local protocol governs the exercise, and when the learner should stop. A woundโs appearance alone does not determine the correct method, and success on a simulator does not certify clinical competence.
The 2024 American Heart Association and American Red Cross first-aid guidelines emphasize direct pressure for initial bleeding control and note that tourniquet use or wound packing depends on the wound and whether its location is amenable. Scenario design should therefore test method selection as well as hand technique.
Five Wound Packing Stations at a Glance
| Station | Build the station | Main skill tested | Success signal |
|---|---|---|---|
| 1. Deep laceration | Wide, visible cavity on a tabletop; moderate flow; only essential supplies | Basic sequence: target, fill, maintain pressure, reassess | Cavity is progressively filled and simulated flow stops |
| 2. Narrow penetrating cavity | Small opening and deeper channel; same supplies and flow as Station 1 | Limited access and pressure continuity without full visibility | Learner maintains contact and eliminates bypass flow |
| 3. Groin or junctional wound | Wearable trainer or manikin; several method options; clear consent and draping rules | Location recognition, positioning, and team access | Appropriate taught method is selected and control survives a handoff |
| 4. Irregular cavity or simulated bone landmark | Uneven cavity or hard internal feature; source location can change | Tactile adaptation without treating force as the solution | Flow stops without a persistent channel around the obstacle |
| 5. Mixed scenario | Two or three wound options plus pressure supplies, gauze, and a training tourniquet | Method selection, correction, reassessment, and communication | Priority wound is controlled, recurrence is detected, and handoff is complete |
Station 1: Deep Laceration
Use an accessible cavity that lets beginners see and feel where the simulated flow begins. Place gloves, training gauze, and a dressing within reach, but remove unrelated equipment during the first attempt.
The learner should identify the simulated source, place the first gauze directly at that point, fill the cavity instead of covering the surface, maintain pressure during each feed, and reassess according to the course-defined process.
Build focus: make loose packing produce a visible side leak. The modelโnot the instructorโs immediate verdictโshould reveal the error.

Station 2: Narrow, Deep Penetrating Cavity
Keep the equipment and flow unchanged, but replace the wide cavity with a smaller opening and deeper channel. A gunshot-style task trainer can provide this geometry; the label describes the simulator, not a universal treatment rule for penetrating injuries.
The learner must maintain source-directed pressure when the full cavity is not visible. After one successful attempt, rotate the model or partly obscure the opening rather than adding noise, time pressure, and new equipment simultaneously.
Build focus: limited access is the only new difficulty. Persistent flow should prompt the learner to consider a missed target, an unfilled channel, or a pressure break.
Station 3: Groin or Junctional Wound
Mount the trainer on a manikin or use a wearable model with a consenting simulated participant. Prebrief touch boundaries, exposure, draping, and the stop signal. Provide several bleeding-control options so the station tests location recognition before packing begins.
The learner should select the method taught for the simulated location, position their hands effectively, request assistance clearly, and maintain control while another person passes gauze or takes over pressure.
Build focus: access and teamworkโnot a faster pumpโcreate the difficulty. Run the station first on a table and then in a wearable or manikin position to isolate that change.
Station 4: Irregular Cavity or Simulated Bone Landmark
Use a model with an uneven space, branch, or clearly identified simulated bone feature. Explain that the hard landmark belongs to the trainer and does not authorize blind probing of a real wound.
The learner should interpret tactile feedback, redirect material around the simulated obstacle, and use flow to identify any remaining channel. Do not score โtouched the boneโ as the endpoint; bone contact is a cue to adapt, not proof of control.
Build focus: change the simulated source location between attempts while keeping the external opening the same. This prevents memorization of one hand path.
Station 5: Mixed Scenario
Present two or three wound models or scenario cards and provide direct-pressure supplies, training gauze, and a commercial training tourniquet. Only one injury should need immediate packing under the course protocol.
After initial control, introduce one event: restart simulated flow after movement, reveal a second wound, shift the pack during transfer, require a teammate to take over, or ask for an emergency-responder handoff.
Build focus: the learner is not told which tool to use. Success requires choosing an appropriate taught method, confirming the result, recognizing recurrence, correcting it, and communicating what happened.

One Scoring Framework for All Five Stations
Use the same core checklist throughout the progression, then add one station-specific item.
| Score domain | What the instructor should see |
|---|---|
| Method selection | Learner explains why the taught method fits the simulated wound and location |
| Source targeting | Initial pressure is directed toward the simulated source |
| Cavity fill | Gauze progressively fills the taught space without a visible bypass channel |
| Pressure continuity | Contact is maintained during feeds and hand transitions |
| Effect verification | Learner uses model feedback to confirm control |
| Reassessment | Renewed flow or instability is detected after the planned event |
| Communication | Requests and handoff include the wound, method, result, and unresolved concerns |
| Station-specific skill | Learner manages limited access, positioning, tactile feedback, or team coordination |
If time is measured, pair it with control of simulated flow and completion of critical actions. Speed alone can reward an incomplete attempt.
A Short Prebrief and Debrief
Before the attempt, state the objective, what is simulated, the success signal, applicable clinical framework, physical boundaries, and stop rule.
Afterward, ask four questions:
- What changed in the model?
- Which action most likely produced that result?
- What one change should be tested next?
- Where might the same problem appear in another station?
INACSLโs Healthcare Simulation Standards of Best Practice recommend measurable objectives and planned prebriefing, facilitation, and debriefing. The wound model is only one part of the learning design.
Conclusion
Progression should come from clearer decisions and harder accessโnot simply from more graphic wound appearances.
Start with a visible laceration, narrow the access, change the body position, add an irregular landmark, and finish with method selection plus reassessment. Across every station, define one main challenge and one observable success signal.
Frequently Asked Questions
Does an instructor need a different trainer for every station?
No. One flow-enabled model can support several objectives by changing its orientation, visibility, learner position, equipment choices, or reassessment event. Add another wound geometry only when it creates a genuinely different access or tactile problem.
Should beginners start with active simulated bleeding?
Not necessarily. Static or low-flow practice can simplify the first hand-position demonstration. Active flow becomes especially useful when the objective is targeting, recognizing pressure loss, or correcting a failed pack.
Can the same checklist score every wound type?
Yes. Keep the core domains stableโselection, targeting, fill, pressure, verification, reassessment, and communicationโthen add one measurable item for the stationโs specific challenge.
