Lesson
Decide Whether the Wound Is Truly Minor
A small surface opening can hide tendon, nerve, vessel, joint, bone, foreign-body, or crush injury. Mechanism, site, depth, contamination, function, and host risk define the pathway.
- Abrasion
- Laceration
- Puncture
- Deep structure
- Closure need
Mechanism predicts hidden risk
Identify closure and exploration needs
Find tendon, nerve, vessel, or joint injury
Life threats precede cleaning
Classify mechanism and tissue
Distinguish scrape, clean incision, irregular laceration, puncture, avulsion, crush injury, and impalement. Record object, force, time, contamination, depth, length, gaping, tissue loss, and foreign material.
Test what the wound can damage
Check active motion, strength, sensation, capillary refill, pulses, color, temperature, and joint function distal to the injury. Compare sides when safe.
Find closure and exploration needs
Deep, gaping, contaminated, facial, hand, joint, tendon, nerve, vessel, bone, or function-threatening wounds may need irrigation, imaging, exploration, closure, or specialist repair.
Recognize safeguarding concerns
An injury pattern or explanation that does not fit the mechanism or developmental ability warrants safeguarding assessment. In a child, unexplained cuts or abrasions on protected sites, multiple symmetric injuries, or injuries before independent mobility raise concern. These findings prompt assessment, not a diagnosis of abuse by themselves. Document objective findings and follow local safeguarding and reporting procedures while addressing immediate safety.
Escalate life threats first
Call emergency services for uncontrolled major bleeding, shock, amputation, evisceration, major impalement, airway threat, or serious chest, neck, abdominal, pelvic, or groin injury. Do not delay to clean the wound.

Lesson
Control Bleeding Without Disrupting Hemostasis
Direct pressure controls most external bleeding. Severe hemorrhage requires emergency activation, trained escalation, rescuer protection, and careful preservation of the forming clot.
- Direct pressure
- Preserve original pad
- Tourniquet
- Shock
- Blood exposure
Prevent a second exposure
Keep original pad; avoid stacking pads
Recognize failure
Use trained decisive control
Protect the rescuer
Use gloves or another barrier when possible and protect eyes and broken skin. Wash exposures and follow occupational or emergency postexposure guidance.
Apply uninterrupted pressure
Place clean gauze or cloth over the wound and press firmly. Keep the original pad in place. If desired, add one pad above it and replace only that added pad when necessary; do not keep stacking pads. Maintain pressure and escalate uncontrolled bleeding.
Recognize severe hemorrhage
Rapid pooling, spurting, amputation, persistent bleeding after firm pressure, or shock signs such as confusion, pallor, sweating, weakness, or collapse require emergency services.
Escalate trained care
Life-threatening extremity bleeding can require a commercial tourniquet. Record application time and do not loosen it casually. Deeply embedded objects are stabilized rather than pulled out.

Lesson
Remove Contamination Without Injuring Viable Tissue
Clean running water and gentle mechanical removal support healing. Blind probing, harsh chemicals, embedded objects, necrosis, and inaccessible debris require another strategy.
- Irrigation
- Mild soap
- Foreign body
- Impaled object
- Debridement
Mechanical removal is central
Do not probe blindly
Stabilize rather than extract
Debridement follows perfusion and tissue
Irrigate and inspect
Wash hands, rinse with clean running water, and use mild soap around the wound. Remove only superficial visible debris that comes away safely. Reinspect the base, edges, and function.
Avoid tissue-toxic rituals
Repeated hydrogen peroxide, alcohol, bleach, or concentrated antiseptic inside tissue can injure viable cells. Stinging is not a measure of effective wound care.
Protect embedded objects
Do not blindly probe or remove a large or deeply embedded object. Stabilize an impaled object and seek emergency care because removal can release tamponade and cause major bleeding.
Use debridement by indication
Devitalized tissue and retained contamination require professional assessment to select safe removal. Ischemia calls for vascular evaluation, not automatic debridement. Pressure-ulcer guidance advises preserving uninfected dry ischemic eschar until arterial flow is restored; acute infection or wet gangrene needs urgent specialist management. Collagenase is not routine acute first aid.

Lesson
Match Enzymatic Debridement to Necrotic Tissue
Collagenase is a prescription debriding enzyme, not routine first aid or an antibiotic.
- Collagenase
- Necrotic tissue
- Compatibility
This is not routine first aid
Silver can reduce activity
The enzyme is not an antibiotic
Established granulation is the endpoint
Use the labeled indication
SANTYL contains 250 collagenase units per gram and is labeled for chronic dermal ulcers and severely burned areas. It digests collagen in necrotic tissue; the label states that healthy collagen and new granulation tissue are spared.
Apply within the wound plan
Use once daily, or more often if the dressing becomes soiled. Keep application within the wound. Stop when necrotic tissue has been removed and granulation is established.
Check compatibility
Some detergents and metal ions, including silver, reduce enzyme activity. Check every cleanser and dressing rather than assuming combinations are compatible. The label identifies saline and Dakin's solution as compatible; this does not make household bleach appropriate wound care.
Monitor infection
Collagenase does not treat infection. If infection fails to respond to treatment, the label directs withholding collagenase until infection remits. Assess perfusion and tissue before debridement; avoid use in collagenase hypersensitivity.

Lesson
Know the Limits of Bleeding-Control Powder
A product that forms a surface seal does not replace emergency hemorrhage control or wound exploration.
- WoundSeal
- External bleeding
- Product limits
Emergency care takes priority
Requires blood to work
Observe package wetting interval
Does not replace wound closure
Identify the product
The reviewed WoundSeal instructions describe hydrophilic polymer and potassium ferrate. The powder requires blood to act; it is not an antibiotic.
Follow the application sequence
For a suitable cleaned external wound that is bleeding, cover the bleeding site with powder and apply pressure for 30 seconds. Leave the resulting seal in place and avoid wetting it for one hour.
Preserve the referral boundary
Do not use for arterial bleeding or visibly infected wounds. It does not replace stitches. Continued bleeding or persistent irritation needs medical attention; do not delay emergency care while repeating applications.
Handle safely
Avoid eyes, inhalation and ingestion. Discard remaining contents after use and do not use damaged, opened or clumped product. Product-specific seal instructions do not change the usual moist-covered approach to an uncomplicated nonbleeding wound.

Lesson
Understand the Biology the Dressing Must Support
Hemostasis, inflammation, proliferation, epithelial migration, contraction, and collagen remodeling overlap. Local moisture, perfusion, tension, nutrition, and repeated trauma shape the outcome.
- Hemostasis
- Inflammation
- Granulation
- Epithelialization
- Remodeling
Stabilize the wound
Differentiate expected from progressive
Support moisture, oxygen, and nutrition
Protect from tension and re-injury
Stabilize hemostasis
Vasoconstriction, platelet adhesion, coagulation, and fibrin form the initial seal. Anticoagulants, antiplatelets, liver disease, bleeding disorders, and repeated dressing removal can destabilize it.
Interpret inflammation by trajectory
Early tenderness and limited erythema can be normal. Progressive pain, warmth, swelling, drainage, streaking, fever, or functional decline is not explained by routine repair.
Support proliferation
Fibroblasts, matrix, capillaries, granulation, contraction, and epithelial migration rebuild the barrier. Moisture balance, oxygen delivery, nutrition, glucose, pressure, edema, and smoking affect this work.
Respect remodeling
Collagen reorganizes for months and never recreates unwounded strength immediately. Tension, repeated injury, joint motion, pigment change, hypertrophic tendency, and sun exposure shape the scar.

Lesson
Build a Clean Moist Protected Healing Environment
Current dermatology guidance favors daily gentle cleansing, plain petroleum jelly, and a protective dressing for uncomplicated minor wounds rather than drying them uncovered.
- Petroleum jelly
- Nonadherent dressing
- Moisture balance
- Daily change
- Adhesive tolerance
Remove contamination without toxicity
Limit drying and scab fracture
Balance drainage and friction
Ordinary bandages daily; sheets vary
Use plain petroleum jelly
Apply a thin layer from a squeeze tube to a clean uncomplicated wound. It reduces drying and scab formation without routine antibiotic exposure.
Cover according to behavior
Use an adhesive bandage or nonadherent pad for many minor wounds. Larger abrasions or selected wounds may need hydrogel, silicone, gauze, or clinician-directed dressings according to drainage and site.
Keep moist, not waterlogged
Excess exudate under an occlusive dressing causes maceration. A dry adherent dressing can strip new epithelium. Match absorption and change interval to the wound.
Inspect and renew
Replace ordinary bandages daily and sooner if wet, dirty, loose, or saturated. Specialized silicone or hydrogel sheets have product-specific change intervals; follow their instructions and the clinical care plan rather than automatically removing them every day. At dressing changes, remove gently, inspect the wound and surrounding skin, and clean and re-cover as directed.

Lesson
Use Topicals Without Creating Dermatitis or Resistance
Most clean minor wounds do not need topical antibiotics. Neomycin and bacitracin can sensitize skin, while harsh antiseptics can damage viable tissue.
- Antibiotic stewardship
- Contact dermatitis
- Petroleum alternative
- Tissue toxicity
- True infection
Most clean wounds need no antibiotic
Contact dermatitis can mimic infection
Cell injury can delay healing
Match depth, organism, and host
Skip prophylactic antibiotics routinely
Daily cleansing, petroleum jelly, and coverage are sufficient for most clean minor wounds. Antibiotics do not replace irrigation, foreign-body removal, drainage, or treatment of deep infection.
Recognize allergic contact dermatitis
A pruritic spreading eczematous rash under or beyond the product area can reflect neomycin, bacitracin, adhesive, preservative, or vehicle allergy rather than infection.
Identify infection multimodally
Pus, yellow or golden crust, progressive pain, warmth, swelling, spreading color change, streaking, fever, or functional decline supports evaluation. Color may look red, brown-red, violaceous, gray, or subtle across skin tones.
Distinguish prescription mupirocin
The reviewed 2% ointment is labeled for impetigo caused by susceptible S. aureus or S. pyogenes, not routine cut prevention. Its label uses a small amount three times daily for up to ten days, with reassessment if no response in three to five days. Do not assume all MRSA remains susceptible.
Respect formulation limits
This skin ointment is not for eyes, nose or other mucosa and should not be mixed with other topical products. Avoid situations allowing substantial polyethylene glycol absorption, especially with moderate or severe renal impairment. The reviewed 2% cream instead covers secondarily infected traumatic lesions up to 10 cm long or 100 square cm due to susceptible S. aureus or S. pyogenes. It is used three times daily for ten days with the same three-to-five-day response check. Pediatric evidence begins at three months for cream versus two months for ointment.
Read OTC antibiotic limits
The reviewed Neosporin Original contains bacitracin, neomycin and polymyxin B. Its label permits a small amount one to three times daily for minor cuts or scrapes, but routine prophylaxis is unnecessary for a clean uncomplicated wound under AAD guidance. Seek advice before use on deep wounds, bites or serious burns; stop for rash, worsening or need beyond one week.
Do not assume neomycin-free means allergy-free
Removing neomycin does not remove the possibility of bacitracin or other ingredient allergy. Choose the simplest appropriate care and review the actual ingredients.
Do not import an old combination routinely
The book lists Cortisporin skin ointment. The retrieved Pfizer label has a 2019 marketing end date and describes steroid-responsive dermatoses with secondary infection, not routine cut care. It limits use to seven days and excludes fungal, viral and tuberculous skin lesions. Hydrocortisone can delay repair or mask infection. This historical label does not establish current availability.
Treat a diagnosed indication
When bacterial infection is established, choose culture, topical, oral, procedural, or urgent care according to depth, organism, severity, host risk, and current guidance. Do not extend self-care blindly.

Lesson
Keep Liquid Films Within Their Label
A consumer liquid bandage can protect a selected minor cut, but it is not a substitute for exploration, sutures or infection assessment.
- Liquid film
- Product label
- Draining wound
- Flammability
Deep injury or infection needs evaluation
No draining wound or application over sutures
Follow labeled frequency; avoid other creams
Stop for worsening or infection
Choose a suitable wound
Use the reviewed New-Skin single-use product only for appropriate minor cuts or scrapes. Seek advice first for deep wounds, bites, serious bleeding or burns, diabetes or poor circulation.
Apply the reviewed formulation
The antiseptic ingredient is benzethonium chloride 0.2%. Clean the area, apply a small amount one to three times daily and let it dry. A second coat is permitted. Do not layer it with other first-aid creams or lotions.
Respect exclusions
Do not use on infected or draining wounds, over sutures, on mucous membranes, in eyes or over large areas. Use beyond one week requires doctor direction. Stop and seek advice for worsening or infection.
Prevent avoidable injury
The product is flammable; keep it away from flame and heat. Temporary stinging can occur. Check other formulations separately because products with similar names can differ.

Lesson
Apply Current Tetanus Prophylaxis by Wound and Immunity
Tetanus prevention requires wound classification, primary-series status, time since the last tetanus-containing vaccine, and selected TIG use. Antibiotics do not prevent tetanus.
- Clean minor
- Dirty major
- Five-year rule
- Ten-year rule
- TIG
TIG never indicated
Puncture and devitalized tissue count
Complete the primary series
Provide immediate passive protection
Classify tetanus exposure
Punctures and wounds containing dirt, soil, feces, saliva, devitalized tissue, crush injury, burns, frostbite, necrosis, or gangrene are dirty or major. Clean minor wounds have lower exposure risk.
Use series status first
Unknown, absent, or incomplete primary series requires age-appropriate tetanus-containing vaccination for every wound. After a complete series, no vaccine is needed when the last dose was less than five years ago.
Use the interval by wound
After a complete series, clean minor wounds trigger vaccination at ten or more years since the last dose. Dirty or major wounds trigger vaccination at five or more years.
Place TIG precisely
TIG is never used for clean minor wounds. For dirty or major wounds, it is indicated with unknown, absent, or incomplete vaccination and for HIV or severe immunodeficiency. When indicated for prophylaxis, give TIG 250 international units intramuscularly. Vaccine and wound care remain necessary when indicated.

Lesson
Recognize Puncture, Functional, and Host Risk
Puncture geometry, hands and joints, feet, retained material, diabetes, neuropathy, vascular disease, immune compromise, anticoagulation, and limited self-care can turn a small wound into a major problem.
- Puncture depth
- Hand function
- Foot risk
- Foreign body
- High-risk host
Foreign body and infection risk
Test motion, sensation, and perfusion
Lower the referral threshold
Adapt the plan
Treat puncture wounds as deep until proven otherwise
A nail, fishhook, glass fragment, needle, or sharp object can carry contamination beneath a small opening. Review object, footwear, trajectory, breakage, joint or bone proximity, and tetanus status.
Protect hand and joint function
Test motion, strength, sensation, perfusion, and wound position during injury. Partial tendon injury can preserve some movement, and small joint penetrations can seed deep infection.
Protect the high-risk foot
Diabetes, neuropathy, ischemia, edema, and immune compromise increase ulcer, infection, osteomyelitis, and delayed-healing risk. An insensate wound still requires careful evaluation.
Adapt care to the person
Fragile skin, anticoagulation, malnutrition, smoking, poor vision, limited dexterity, language, supplies, transport, housing, and caregiver support change dressing and follow-up safety.

Lesson
Measure Healing and Define the Return Rule
Wound follow-up tracks closure, drainage, pain, surrounding skin, function, perfusion, infection, foreign body, and host factors. A stalled or worsening wound is diagnostic information.
- Infection trajectory
- Delayed healing
- Dehiscence
- Scar care
- Teach-back
Compare over time
Recognize infection and dehiscence
Find the cause of delay
Protect after epithelialization
Measure the trajectory
Photograph or document size, depth, edge, drainage, pain, surrounding skin, sensation, motion, and temperature when useful. Compare over time rather than relying on one appearance.
Escalate infection or dehiscence
Progressive pain, warmth, swelling, pus, odor, streaking, fever, systemic illness, edge separation, exposed deeper tissue, or functional decline needs direct evaluation.
Investigate stalled healing
Review retained foreign body, infection, ischemia, pressure, edema, glucose, nutrition, smoking, medications, dressing moisture, adhesive injury, and wrong diagnosis.
Transition to scar protection
After epithelial closure, protect from re-injury and sun. Use clinician-directed silicone or scar care when appropriate. Do not place sunscreen or unverified scar products into an open wound.
