Wound Care in Emergencies: Complete Field Guide

Wound Care in Emergencies: The Field Guide

Every serious injury is a race against two clocks: the bleeding clock and the infection clock. When EMS response is delayed — or impossible — those clocks run on your watch.

This is not a guide about minor scrapes. This is a field manual for managing wounds when definitive care is hours or days away: uncontrolled hemorrhage, deep lacerations, puncture wounds, avulsions, amputations, and the slow-motion threat of infection. The techniques here are drawn from Tactical Combat Casualty Care (TCCC), Wilderness First Aid (WFA), and civilian trauma protocols.

For the broader framework — IFAKs, kit tiers, chronic condition prep, and the evacuate vs. improvise decision — see the emergency medical preparedness guide.

Wound Classification: Know What You Are Dealing With

Before you touch a wound, classify it. The classification determines your entire treatment approach.

Minor (Superficial)

Abrasions, shallow cuts, and lacerations that do not penetrate below the dermis. Capillary bleeding only — oozes, does not flow. No deep structure involvement (tendon, bone, joint).

Treatment: Clean, cover, monitor. Steri-Strips or adhesive bandage for closure if needed.

Moderate (Deep, Needs Closure)

Full-thickness lacerations through dermis into subcutaneous tissue. Brisk venous bleeding. May gape open. Edges can be approximated with closure techniques.

Treatment: Irrigate thoroughly, achieve hemostasis, close with appropriate technique (see closure section), monitor for infection.

Severe (Arterial or High-Volume Bleeding)

Bright red blood that pulses or flows rapidly. Extremity wounds or vascular injuries. Requires immediate hemorrhage control — not just a bandage.

Treatment: Direct pressure, wound packing, tourniquet for extremities. This is the domain of Stop the Bleed protocols.

Life-Threatening (Major Hemorrhage)

Junctional wounds (groin, axilla, neck), extremity amputations, large avulsions, or any wound with blood loss that is visibly rapid and not slowing. The patient may show signs of shock.

Treatment: Simultaneous hemorrhage control and evacuation activation. Do not delay transport to provide perfect wound care.

Bleeding Control: The Progression

Apply the minimum intervention that stops the bleeding. Escalate only when the previous step fails. Every 30 seconds you spend deciding costs blood volume.

Step 1: Direct Pressure

The majority of bleeding wounds stop with well-applied direct pressure.

How to do it correctly:

Glove up before contact with blood if possible
Apply a clean gauze pad (4x4 minimum) directly over the wound
Press firmly with the heel of your hand — full body weight if needed
Hold without lifting or peeking for a minimum of 5 minutes (check clock, do not guess)
If gauze saturates, do not remove it — add more gauze on top and increase pressure
After 10 minutes of maximal direct pressure with no improvement: escalate

Common mistakes: Lifting the gauze to check, applying light pressure, using cotton balls or tissue (they stick and impair clot formation).

Step 2: Wound Packing with Hemostatic Gauze

For deep, cavitating wounds — gunshot wounds, impalement sites, deep stab wounds — where direct surface pressure cannot reach the bleeding source.

Hemostatic gauze options:

Product	Mechanism	Notes
QuikClot Combat Gauze	Kaolin-impregnated	DoD-approved, standard of care
Celox Rapid	Chitosan-based	Effective on anticoagulated patients
ChitoGauze	Chitosan-based	Similar to Celox formulation
Plain gauze (fallback)	Physical pressure only	Less effective, use when nothing else available

How to pack a wound:

Expose the wound — cut away clothing if necessary
With a gloved finger, locate the deepest part of the wound
Begin packing hemostatic gauze starting at the deepest point, working outward
Use your finger to push each layer firmly into the wound cavity
Use the entire roll — fill the wound completely
Apply firm direct pressure over the packed wound for 3 minutes minimum
Hold until bleeding stops or you can apply a pressure bandage

Do not pack: Chest wounds with penetrating thoracic injury (seal instead), abdominal evisceration, eye injuries.

Step 3: Tourniquet

Tourniquets are for extremity bleeding (arms and legs) that cannot be controlled by packing — or when packing is not feasible (multiple casualties, high-pressure evacuation scenario). Modern evidence from combat medicine has thoroughly refuted the myth that tourniquets cause permanent limb damage when properly applied and removed within 2 hours.

Tourniquet Application: CAT Gen 7 Step-by-Step

The Combat Application Tourniquet (CAT) Generation 7 is the current DoD-standard tourniquet. The SOFTT-W is equally effective; the application mechanics are similar. Only use genuine CAT or SOFTT-W tourniquets — counterfeit versions fail under pressure and have caused documented deaths.

When to apply:

Extremity amputation (apply immediately without attempting pressure first)
Arterial bleeding from an extremity not controlled after one attempt at wound packing
Scene with multiple casualties where rapid movement is required

CAT Gen 7 application — step by step:

Expose the limb. Cut away clothing above the wound. You need to see skin.
Position the tourniquet. Place 2 to 3 inches above the wound (proximal). Never apply over a joint. For amputations or partial amputations, place as high as possible on the limb.
Thread and route. Pass the tail through the buckle and back through the friction adapter. Pull tight against the skin — snug, but it will tighten further.
Secure the band. Route the tail back through the second buckle slot. Pull the free tail to tighten. The band should be firm against the skin.
Tighten the windlass. Twist the windlass rod clockwise until bleeding stops. This is painful — expected and necessary. Do not stop because the patient says it hurts.
Verify cessation. The wound stops bleeding. For limb amputations, confirm no distal pulse (that is the goal).
Lock the windlass. Secure the windlass rod in the clip. Wrap the free end of the strap around the windlass and secure with the velcro tab.
Mark the time. Write the application time in large letters directly on the tourniquet with a permanent marker (e.g., “TQ 14:32”). If no marker, write on the patient’s forehead or tape.
Do not remove. Once applied in the field, a tourniquet stays on until definitive care. Removal can trigger re-bleeding and sudden hemodynamic collapse. Only a trained provider should consider conversion.

Time limits: Tourniquet application is safe for 2 hours. After 2 hours, risk of nerve and muscle damage increases. Combat data shows limb salvage is high with tourniquet times under 2 hours. The risk of death from removed tourniquet vastly outweighs the risk of tourniquet-related injury.

Junctional wounds (groin, axilla, neck, pelvis): Tourniquets cannot be applied. Pack aggressively with hemostatic gauze and apply the maximum sustained manual pressure you can maintain. Junctional Emergency Treatment Tool (JETT) or SAM Junctional Tourniquet (SJT) are specialized devices for these sites.

Wound Irrigation: The Most Overlooked Step

Irrigation is the single most evidence-supported intervention for preventing wound infection. A 2013 systematic review in the Cochrane Database found that high-pressure irrigation significantly reduces infection rates compared to low-pressure or no irrigation.

Irrigation fluid options (in order of preference):

Normal saline (0.9% sodium chloride) — sterile, isotonic, ideal
Potable drinking water — equivalent to saline in multiple RCTs; acceptable in field settings
Water purified with filtration or chemical treatment — acceptable if nothing else is available

What NOT to use in open wounds:

Hydrogen peroxide — damages fibroblasts and impairs healing
Full-strength povidone-iodine (Betadine) — cytotoxic at concentrations above 0.5%
Alcohol — destroys tissue, causes severe pain, no benefit over saline

Pressure irrigation technique:

The goal is mechanical removal of bacteria and debris. Gentle pouring does not accomplish this. You need a pressurized stream.

Preferred method: 20 to 35 mL syringe (irrigation syringe) with an 18-gauge angiocath or splash guard — delivers 8 to 15 PSI, the effective range
Field improvisation: Fill a clean plastic bag with water, poke a small pinhole (approximately 18-gauge equivalent), squeeze firmly for a jet stream
Minimum volume: 100 mL per wound. For heavily contaminated wounds, use 250 mL or more
Technique: Hold the syringe 2 to 3 cm from the wound. Irrigate the full wound cavity, including undermined edges. Rotate the stream direction to cover all surfaces
Debris removal: After irrigation, remove any visible debris (gravel, dirt, clothing fibers) with fine-point tweezers. Irrigate again after debris removal

Wound Closure Options

Not every wound should be closed. The decision tree matters as much as the technique.

When to close:

Clean wound (minimal contamination)
Less than 6 to 8 hours old (ideally under 4 hours for high-risk locations)
Adequate irrigation has been performed
Wound edges can be approximated without tension
No signs of infection

When to leave open (heal by secondary intention):

Wounds over 8 hours old
Animal bites (high infection risk)
Puncture wounds (depth cannot be fully irrigated)
Heavily contaminated wounds (field injuries with soil/fecal contamination)
Any signs of active infection
Uncertainty about wound cleanliness

Steri-Strips and Butterfly Closures

Best for: Superficial lacerations, low-tension wounds, wound edges that approximate easily, pediatric patients where suturing is not feasible.

How to apply Steri-Strips:

Ensure wound and surrounding skin are completely dry (use gauze to blot)
If available, apply tincture of benzoin to the skin 1 cm on either side of the wound — dramatically improves adhesion
Place the first strip perpendicular to the wound, bridging both sides, starting in the center of the wound
Apply gentle tension to approximate the wound edges before pressing the strip down
Add additional strips every 3 to 4 mm along the wound length
Apply one strip parallel to the wound on each side (cross-hatch pattern) to reinforce adhesion

Limitations: Do not use on scalp (hair prevents adhesion), over joints under high tension, on moist or oily skin.

Skin Stapler

Best for: Scalp lacerations, long linear lacerations on trunk or extremities, fast application under pressure, multiple wounds.

Advantages: Fastest technique. A 4-inch scalp laceration closes in under 30 seconds with a stapler versus several minutes with sutures. Less technically demanding.

Skill required: Moderate. Staple placement and tissue approximation technique require practice but are learnable.

How to use:

Align wound edges — an assistant holding the edges together improves results significantly
Position the stapler head over the wound center — the wound edge alignment guides are on the device
Press the stapler firmly against the skin and fire — one staple per trigger press
Space staples approximately 4 to 5 mm apart, starting at one end and working to the other
Remove staples at 5 to 7 days (extremities), 7 to 10 days (scalp, trunk) using a dedicated staple remover

Do not use: On face, hands, or over joints.

Tissue Adhesive (Dermabond / Medical Cyanoacrylate)

Best for: Clean, superficial, low-tension wounds on adults and children. Particularly good for facial lacerations. Fast, painless application.

Skill required: Low — but technique errors cause adhesion failure.

How to apply:

Wound must be dry, clean, and edges well-approximated
Hold wound edges together with fingers or forceps
Apply a thin layer of tissue adhesive over the wound — do not let it run into the wound
Hold edges together for 30 to 60 seconds while adhesive polymerizes
Apply 2 to 3 additional thin layers at 30-second intervals
The adhesive sloughs off naturally in 7 to 10 days — do not peel

Critical warning: Keep adhesive out of the wound interior. It does not promote healing inside the wound — it must bridge the surface only.

Suturing

Best for: Deep lacerations, wounds under tension, wounds requiring layered closure, wounds in cosmetically sensitive areas.

Skill required: High. Suturing without training produces poor closure and carries real risks: tissue strangulation, uneven tension, needle stick injury, improper knot tying. Take a suture course before you need this skill.

Basic overview for trained individuals:

Simple interrupted sutures are the most versatile and forgiving:

Use 3-0 or 4-0 nylon for skin (non-absorbable)
Use 3-0 Vicryl (absorbable) for deep tissue layers before skin closure
Place sutures 4 to 6 mm from wound edges, 4 to 6 mm apart
Tie with a surgeon’s knot (double first throw) — minimum 3 throws for security
The wound edges should be approximated, not strangulated — if tissue blanches around the suture, it is too tight
Remove at 5 to 7 days (face), 7 to 10 days (extremities/trunk), 10 to 14 days (back, scalp)

Absorbable sutures (Vicryl, Monocryl): For deep tissue layers only in the field — they dissolve, eliminating the need for suture removal in scenarios where follow-up is uncertain.

Infection Monitoring: The Timeline

Understanding the timeline of wound infection lets you catch problems before they become life-threatening.

Hours 0 to 24: Normal inflammation — redness, warmth, swelling, and pain at the wound margins. This is the body’s innate immune response, not infection. Expected and normal.

Hours 24 to 72: Wound should begin improving. Normal trajectory: decreasing pain, stable or decreasing swelling, wound edges beginning to adhere. Any worsening at this stage is a red flag.

Hours 48 to 96: Early infection warning signs

Redness expanding beyond the original wound margins
Increased warmth spreading outward
Purulent discharge (yellow, green, or cloudy drainage) — distinct from clear serous drainage, which is normal
Increasing pain after an initial period of improvement
Low-grade fever (under 101°F)

Cellulitis is skin and subcutaneous tissue infection spreading outward from the wound. Characterized by expanding red, warm, tender skin without abscess formation. Requires oral antibiotics (amoxicillin-clavulanate or cephalexin first line; doxycycline if penicillin allergic) and close monitoring. Mark the border of the redness with a permanent marker — if it expands past the mark within 4 to 6 hours, escalate immediately.

Hours 72 to 120: Serious infection escalation signs — prepare to evacuate

Abscess formation: fluctuant (fluid-filled), tender mass under the skin
Purulent wound with expanding cellulitis
Red streaking extending from wound toward lymph nodes (lymphangitis — a sign of rapidly spreading infection)
High fever (over 101°F)
Increasing systemic symptoms: malaise, nausea, chills

Sepsis indicators — evacuate immediately:

Fever over 101°F (or hypothermia under 96°F — equally concerning)
Heart rate consistently over 90 to 100 beats per minute
Respiratory rate over 20 breaths per minute
Altered mental status or confusion
Hypotension (systolic blood pressure under 90 mmHg)
The combination of an infected wound with any two of the above criteria is sepsis until proven otherwise

Specific Wound Scenarios

Puncture Wounds

Puncture wounds are deceptive. The small entry site conceals significant depth and contamination.

Why they are dangerous: The wound track cannot be adequately irrigated. Anaerobic bacteria thrive in deep, narrow, poorly oxygenated environments. Punctures carry high risk for tetanus and abscess formation.

Treatment:

Irrigate the opening with syringe pressure, directing fluid into the track as far as possible
Do not close the wound — leave it open for drainage
Soak in warm clean water for 15 minutes twice daily
Apply povidone-iodine diluted to 1% at the wound surface (not deep inside)
Monitor closely for abscess formation (expanding tenderness, fluctuant mass)
If nail puncture through shoe, footwear, or ground contact: high risk for Pseudomonas aeruginosa — requires ciprofloxacin (not amoxicillin-clavulanate)

Tetanus risk: Any puncture wound, particularly from rusty metal, soil contamination, or animal contact, requires tetanus prophylaxis. If vaccination status is unknown or last booster was over 10 years ago (or over 5 years for high-risk wounds), the patient needs a Td booster. In austere settings without access: clean aggressively and monitor, accepting elevated risk.

Avulsions

An avulsion is a wound where tissue is forcibly torn away — partially or completely. Common causes: machinery, animal bites, motor vehicle accidents, degloving injuries.

Partial avulsion (tissue still attached):

Do not cut off the flap — even poorly attached tissue can survive if circulation is maintained
Irrigate both the wound bed and the underside of the flap
Reposition the flap as anatomically as possible
Secure with Steri-Strips or simple sutures at the edges — no tension stitches
Cover with non-adherent dressing (petroleum gauze) and change daily
Evaluate viability at each dressing change — viable tissue is pink, perfused; non-viable tissue is dark, dusky, or black

Complete avulsion (tissue lost):

Clean and irrigate the wound bed
Leave open — there is nothing to close
Cover with non-adherent wet saline dressing, changed every 12 to 24 hours
Healing occurs by granulation — slow, but effective for wounds under 2 to 3 square centimeters

Embedded Objects

Impalement injuries — objects protruding from the body.

The cardinal rule: do not remove the object in the field.

An embedded object may be tamponading (plugging) a vascular injury. Removal can cause sudden, catastrophic hemorrhage that cannot be controlled. The exception is objects in the airway that are causing obstruction — these must be removed.

Management:

Stabilize the object: build a “doughnut” ring of gauze pads around the base of the object to prevent movement
Secure the stabilization ring with bandages wrapped around it, not across the object
Pad the object against body movement — particularly for transport
Treat for shock (position flat, maintain warmth, monitor vitals)
Move the patient to definitive care without removing the object

Amputations

Partial amputation (tissue bridge remaining):

Control bleeding with tourniquet applied proximal to the injury
Do not complete the amputation — even a thin tissue bridge may contain vessels that support viability
Wrap the distal part in clean, moist saline gauze and splint to prevent further separation
Evacuate urgently — replantation is time-sensitive (6 to 8 hours for digits, 4 to 6 hours for major limbs)

Complete amputation:

Apply tourniquet immediately — this is a tourniquet-before-packing situation
Control stump bleeding with wound packing after tourniquet placement
Preserve the amputated part: Wrap in clean saline-moistened gauze, place in a sealed plastic bag, then place that bag in ice water (not direct ice contact). This extends viable replantation window significantly.
Evacuate immediately — do not delay for wound management beyond tourniquet and stump packing

Trench Foot

Trench foot (immersion foot) is a non-freezing cold injury caused by prolonged exposure to cool, wet conditions — not necessarily freezing temperatures. It was the leading cause of non-battle casualties in both World Wars and remains a significant threat in extended outdoor emergencies, flooding scenarios, and any situation where foot moisture cannot be managed.

Causes and Risk Factors

Trench foot develops when feet are wet and cool (32 to 59°F / 0 to 15°C) for an extended period — typically 12 hours or more. The mechanism is vasoconstriction causing tissue hypoxia, not direct cold damage. Risk increases sharply with:

Tight footwear restricting circulation
Immobility (standing in water vs. walking)
Dehydration and malnutrition
Tobacco use (additional vasoconstriction)
Flooding or water operations lasting over 8 hours

Stages and Presentation

Stage 1 (during exposure): Foot feels cold, numb, and heavy. Skin is pale or mottled. Reduced sensation but still able to bear weight.

Stage 2 (rewarming phase — most dangerous): Intense burning, itching, and pain begin when feet warm up. Skin becomes red, swollen, blistered. Small blisters may form. Pulses are bounding. This paradoxical worsening is normal and expected — it reflects reactive hyperemia as vessels dilate after prolonged spasm.

Stage 3 (days 2 to 7): Edema peaks. Blisters may rupture. Deep tissue damage becomes apparent. In severe cases, tissue death (gangrene) can occur.

Prevention

Prevention is far easier than treatment:

Change into dry socks every 8 to 12 hours — carry multiple pairs
Remove boots and dry feet completely whenever halted for over 30 minutes
Foot powder (antifungal) reduces moisture retention
Avoid lacing boots too tight
Keep moving — activity maintains circulation

Treatment

In the field:

Remove wet footwear and socks immediately
Gently dry the feet with a clean cloth — pat, do not rub
Allow feet to warm slowly and naturally in a dry environment — do not apply direct heat (fire, heating pad), which can burn insensate tissue
Elevate both feet to reduce edema
Do not puncture blisters unless they are tense and severely limiting function
Keep feet clean and dry — change dressings daily if blisters open
Do not allow the patient to walk on severely affected feet if avoidable

Medications:

Ibuprofen for pain and inflammation
Diphenhydramine for the intense itching of Stage 2

Evacuation criteria: Blistering that covers significant areas of the foot, signs of secondary infection, any tissue that appears dark or frankly necrotic, or inability to bear weight after 24 to 48 hours of proper treatment.

Frequently Asked Questions

What is the correct order for bleeding control?

Follow the hemorrhage control progression: (1) direct pressure with gauze — 5 to 10 minutes, firm and continuous; (2) wound packing with hemostatic gauze for deep or cavitating wounds; (3) tourniquet for extremity bleeding that cannot be controlled by packing. Never skip to tourniquet on trunk, neck, or groin — pack those wounds instead.

How tight should a tourniquet be applied?

A tourniquet must be tight enough to stop arterial blood flow — the bleeding should stop within 60 seconds of application. A tourniquet that is 'painful but not too tight' is almost certainly not tight enough. Tighten the windlass until bleeding stops, then lock it. Expect the patient to report significant pain — that is correct and expected. Note the application time in permanent marker on the tourniquet.

How do you clean a wound in the field without a hospital?

Irrigation is the single most effective action for wound infection prevention. Use a 20 to 35 mL syringe (or a plastic bag with a pinhole) to deliver a high-pressure stream of clean water or saline directly into the wound. Use at least 100 to 250 mL of fluid per wound. Remove visible debris with tweezers. Do not use hydrogen peroxide or full-strength iodine in open wounds — both damage tissue and impair healing.

When is it safe to close a wound in the field vs. leave it open?

Close clean wounds that are less than 6 to 8 hours old, located on low-tension, low-contamination areas (forehead, scalp, trunk). Leave open: animal bites, puncture wounds, wounds over 8 hours old, visibly contaminated wounds, wounds with signs of infection, or any wound you are not confident is fully clean. An open wound that heals by secondary intention (granulation) is far safer than a closed wound that traps infection inside.

What are the early signs of wound infection and when does it become serious?

Watch for the classic inflammation signs in the first 24 to 72 hours: redness, warmth, swelling, and pain — these are normal if mild and localized. Concerning signs appear at 48 to 96 hours: expanding redness beyond wound edges (cellulitis), yellow or green purulent discharge, increasing pain after initial improvement, and fever. Sepsis warning signs — fever over 101°F, rapid heart rate, confusion, hypotension, or red streaking (lymphangitis) from the wound — demand immediate evacuation. Do not wait.

Can you use superglue to close a wound?

Consumer cyanoacrylate (Krazy Glue, Super Glue) is not sterile and contains solvents that are toxic to tissue. Medical-grade tissue adhesive such as Dermabond uses a formulation specifically designed for skin — it is appropriate for clean, superficial, low-tension wounds. In a true austere emergency with no alternatives, consumer super glue has been used successfully, but it carries higher infection risk and tissue irritation. It is a last resort, not a standard technique.
