Comprehensive Guide to Advanced Medical Moulage and Simulation Strategy

Core Principles of Moulage: The Strategic Framework

• Foundational Objective: The primary goal of moulage is meeting learning objectives more efficiently through science-backed realism. Increased realism correlates directly with learner "buy-in" and improved educational outcomes.
• The Three Killers of Moulage: Every effect must be evaluated against three critical constraints:
  • Time: This includes preparation time, application time, and the back-end time required for cleanup.
  • Effort: The physical and mental energy required to sustain the effect over multiple iterations.
  • Money: This calculation must incorporate the cost of materials, the hourly rate of the artist, and the logistical costs of cleanup.

Strategic Planning and the 80-15-5 Framework

• The 80-15-5 Rule for Mass Casualty Exercises (MCE): This mental framework organizes victims and artists according to skill and injury severity:
  • $80\%$ of Victims: These patients represent the "walking wounded" or those with superficial injuries such as scrapes, minor abrasions, and light lacerations. These should be assigned to novice artists (e.g., volunteers who are excited by the novelty of the event) as the techniques can be taught in five minutes.
  • $15\%$ of Victims: These patients have slightly more advanced injuries requiring more time, effort, and materials. These are assigned to artists with moderate experience who can be trusted to maintain quality without constant supervision.
  • $5\%$ of Victims: These are the most advanced, time-consuming injuries (e.g., complex trauma for stakeholders or brochures). These are reserved for the most expert artists present.
• Timeline for Mass Casualty Planning:
  • Preliminary planning should begin at least $6$ months to a year in advance.
  • The immediate aftermath of an event is the best time to debrief and begin planning for the following year.
  • Short timetables (e.g., $30$ to $45$ days) are generally insufficient for large-scale events involving hundreds of victims.
• Logistical Case Study: Vitals Trending: In the Dayton area citywide exercises, organizers initially used a trifold paper system with taped sections to trend vitals. Paramedics, being efficient learners, often ripped open all sections at once, ruining the simulation timeline. The preferred method is using three different colored, sealed envelopes, which enforces the chronological progression of the simulation.

Professional Resource Management: "The Morgue"

• Reference Preservation: Educators must maintain a "morgue"—a private digital folder of real-world injury images. This ensures accuracy and provides a standard for faculty requests.
• The Problem with Google Searches: Searching for terms like "large laceration" often returns images of other people's special effects makeup. Replicating another artist's work results in a "copy of a copy," where artistic biases and inaccuracies are compounded. Only real medical references should be used.
• Key Literature and Experts:
  • Thomas Plouts: An industry expert on Instagram who has provided makeup for major medical television dramas such as Grey's Anatomy and The Knick.
  • War Surgery in Iraq and Afghanistan: A government-published medical text with extensive references for blast trauma and burns. It is available as a free PDF download of approximately $75\text{MB}$.
  • Special Effects Guide of Real Wounds and Injuries: A reference-heavy book available on Amazon for approximately $30$ to $35$ dollars.
  • The Monstrous Makeup Manual by Michael Spatola: Volume $2$ is particularly useful for medical simulation as it focuses on trauma rather than fantasy creatures.
  • Todd Debreceni: Author of foundational texts regarding special effects makeup application.

Clinical Accuracy in Moulage

• Visualizing Cyanosis: Cyanosis should not be interpreted as a literal "blue" color (the "Smurf" effect). Instead, it represents the body being "devoid of life."
  • On lighter skin tones, this involves removing pinks and vital colors.
  • On darker complexions, this manifests as an "ashy" appearance. Application must be culturally respectful and anatomically accurate.
• Anatomical Integrity: Injuries must follow physiological reality. For instance, a femur fracture prosthetic cannot be meaningfully placed on a forehead.
• Stages of Shock: Reference videos, such as documented cases of femoral artery injuries in bank robberies, provide objective views of how a patient's complexion and behavior change as they decompensate from stage zero to near-death.

Safety Protocols: Physical and Psychological

• Responsibility: The artist is responsible for the safety of the crew, the equipment, and the volunteers.
• Latex Prohibitions: Liquid latex, foam latex, and latex-based appliances should be eliminated from medical simulation. Even if an individual has no known allergy, chronic exposure can trigger an allergic response. In clinical settings, the risk of a volunteer experiencing tingling or anaphylaxis is an unacceptable liability.
• Ocular Safety:
  • "Bloody eye" drops are expensive, degrade quickly after opening, and are impractical for long simulations.
  • Alcohol-activated makeups should never be used near the eyes due to the risk of irritation and contact lens damage.
  • Impalements near the eye must include a custom-fitted plastic safety backing plate to prevent the prosthetic from causing a real injury if the volunteer trips.
• Environmental Risks: Do not place volunteers on cold concrete floors or in running water without a plan for thermal regulation. Hypothermia can occur even in $110\text{-degree}$ weather if a volunteer is left damp in the shade.
• Psychological Safety: Artists must pre-brief volunteers on the specific scenario.
  • Incident Reference: Paul Savage (from the Battles with Bits of Rubber podcast) once prepared a bilateral femur fracture scenario for a volunteer who unexpectedly went into shock. It was later discovered she had lost both parents in a car accident.
  • Protocol: If a volunteer is mentally overwhelmed, they must be cleaned up, thanked, and dismissed without being made to feel guilty.

Technical Application and Materials

• Product Analysis: Nose and Scar Wax: While ubiquitous and cheap, this material is generally poor for medical simulation. It is sticky, lacks durability, and destroys the artist's "Time, Effort, and Money" investment as soon as a student applies medical pressure, causing the wax to deform.
• Stipple Sponge Alternative: Commercial stipple sponges cost approximately $3$ dollars each. A more efficient alternative is "reticulated foam" used as fish filter medium in aquarium supply stores. Large sheets can be purchased for roughly $11$ dollars and cut into hundreds of disposable pieces.
• Hygiene and Cross-Contamination:
  • Never "double-dip" applicators into cream makeup pots.
  • Use a palette knife or a tongue depressor (cut at a $45^{\circ}$ angle) to transfer pigment to a disposable artist paper palette.
  • Label makeup wheels "Not for Human Use" if their history of contamination cannot be certified.
• The Bruise Creation Process ("The Dance"):
  • Preparation: Pick and pull the corners of a latex-free makeup wedge to create an organic, non-uniform surface. Avoid straight lines.
  • Color Theory ($0 - 1$ hour bruise): Focus on reds, pinks, and purples. Avoid yellows and greens, which indicate older injuries.
  • Application: Use an "off-angle" dabbing motion rather than a uniform sewing-machine motion. This is called "The Dance."
  • Blending: Crinkle a brown paper towel (for texture), spray it with isopropyl alcohol, and use it to blend the "goobery" or thick areas of pigment into a nebulous, organic cloud.
  • The Rule of Red: In blunt force trauma, the center of the impact site often remains clear of bruising; ensure the pigmentation reflects the mechanism of injury.

Questions & Discussion

• Question: Can I print an image of a pressure ulcer from Google and tape it to a mannequin?
• Response: While this meets a learning objective, it is the least efficient form of moulage and is unlikely to provide the necessary "buy in" that realistic three-dimensional moulage offers.
• Question: What should I do if my cream makeup doesn't have an expiration date?
  • Response: Reputable brands like Ben Nye typically provide this information. If the date is missing and the material appears "icky" or contaminated, it must be cycled to mannequin use only or discarded.
• Question: How can we simulate an amputation if we don't have a budget for professional amputee actors?
• Response: "Stop hiding the leg." Do not bind a volunteer's leg back or bury it in sand, as this creates a real risk of compartment syndrome. Instead, acknowledge the learning objective (e.g., tourniquet application). A femoral bleed on a fully intact leg requires the same clinical treatment pathway as an amputation. The learning objective is met without the safety risk of trying to "hide" a limb.
• Question: Where do you find the sponges and retractors discussed?
• Response: Reticulated foam is found at aquarium stores or online. Scissor retractors and trauma shears are essential for MCE kits to prevent equipment from "walking away." Reliable, inexpensive retractors are available on Amazon.
