Dressings: Protective Wound Coverings

A dressing is any material used to protect a wound, typically made of cotton.

Uses of Dressings:

  1. Bleeding Control: To help stop blood flow from the wound.

  2. Infection Prevention: To create a barrier against germs and reduce the risk of infection.

  3. Discharge Absorption: To soak up any fluids or pus draining from the wound.

  4. Further Injury Prevention: To shield the wound from bumps, friction, and external harm.

Important Considerations:

  • Size: Dressings should extend at least 2.5cm (1 inch) beyond the wound edges.

  • Sterility: Ideally, dressings should be sterile to prevent introducing microorganisms into the wound.

  • Absorbency: Dressings should be able to absorb moisture and wound discharge, preventing skin maceration around the wound.

  • Breathability: Dressings should allow air circulation to promote wound healing.

Types of  dressings

  1. Adhesive Dressings (Plasters):

    • Cloth-based with adhesive on one side for sticking to the skin.

    • Suitable for small, dry, and clean wounds.

    • Apply to clean, dry skin around the wound.

    • Avoid touching the adhesive or wound contact pad with unsterilized hands.

  2. Sterile Dressings:

    • Best for initial first aid on larger wounds.

    • Come sealed in protective packaging to maintain sterility.

    • Do not use if the packaging is damaged or open.

    How to Apply Sterile Dressings:

    • Open both outer and inner packaging layers.

    • Hold the folded dressing and attached bandage.

    • Position the dressing over the wound, keeping the wound-contacting side sterile.

    • Unfold the dressing to cover the wound completely.

    • Use the short end of the bandage to secure the dressing initially, then firmly wrap the longer bandage around the limb like a roller bandage.

  3. Gauze Dressings:

    • Lightweight coverings, suitable for minor wounds like gunshot wounds.

    • Use when sterile dressings are unavailable.

    • Can be combined with cotton wool padding for extra absorbency.

    • Secure with a bandage or adhesive dressing.

    • In emergencies, any clean, soft, absorbent material can be used as a temporary dressing, held firmly in place.

General rules for applying dressings
  • Hand Hygiene: Wash hands thoroughly before and after dressing application.

  • Wound Cleaning (if applicable): For minor wounds with controlled bleeding, clean the wound and surrounding skin before dressing.

  • Sterile Technique: Avoid touching the wound or the part of the dressing that will contact the wound.

  • Respiratory Hygiene: Do not talk or cough directly over the wound or dressing.

  • Padding & Bandaging (if needed): For non-adhesive dressings, use cotton wool pads and bandage to control bleeding and absorb discharge.

  • Swab Use: Use a swab soaked in antiseptic or disinfectant only once for wound cleaning.

  • Dressing Slippage: If a dressing slides off before securement, discard it and use a fresh one to prevent contamination.

  • Direct Placement: Always place dressings directly onto the wound, avoid sliding them from the side.

Bandaging
Bandaging: Material for Support and Immobilization

Bandaging involves using gauze or cloth to support, hold, or immobilize body parts. It’s the technique of applying roller bandages to different body areas.

Purposes of Bandaging:
  1. Bleeding Control: To apply pressure and help stop bleeding.

  2. Immobilization: To restrict movement of sprained or fractured limbs.

  3. Splint Securement: To hold splints in place for fractures.

  4. Wound Protection: To shield open wounds from dirt and contaminants.

  5. Support for Circulation Issues: To provide support for conditions like varicose veins or poor circulation.

  6. Swelling Reduction: To apply compression and minimize swelling.

Types of bandages

There are three main types of bandages:

  1. Triangular Bandages

  2. Roller Bandages

  3. Tubular Bandages

1. Triangular bandages
  • Made of cloth.

  • Commonly used as arm slings.

  • Used to secure dressings and immobilize injured limbs.

  • Can be unfolded to create scalp bandages.

    Modifications:

    • Broad Fold Bandage: (Explanation not provided in original text, but broadly used for arm slings and larger areas).

    • Narrow Fold Bandages: Used for ankle and foot immobilization. Also to secure dressings on limbs.

2. Roller bandages
  • Made of cotton gauze or linen.

  • Secured with pins, clips, tape, or by tying knots.

    Uses:

    • To keep dressings in place.

    • To apply pressure to control bleeding.

    • To support sprains and strains, reducing pain.

    Types of Roller bandages:

    1. Crepe Bandages:

      • Provide firm support to injured joints.

      • Secure dressings firmly over wounds.

      • Allow good air circulation.

    2. Open Weave Bandages:

      • Used for holding light dressings.

      • Permit ventilation due to their loose weave.

      • Do not provide pressure or strong joint support.

    3. Conforming Bandages:

      • Secure dressings, especially on fingers and toes.

      • Provide support to digit joints.

3. Tubular Bandage:

  • Seamless, tubular fabric rolls.

  • Elasticized versions support joints like elbows or ankles.

  • Tubular gauze bandages use a special applicator.

  • Suitable for securing dressings on fingers or toes, but not for bleeding control.

    Method for Tubular Gauze Bandage (Finger):

    1. Cut a piece of tubular gauze ~2.5 times the finger’s length. Load it onto the applicator. Slide applicator over finger and dressing.

    2. Hold gauze end, pull applicator beyond fingertip, leaving a gauze layer. Twist applicator twice to seal end.

    3. Hold gauze base, push applicator back to apply a second layer. Remove applicator.

    4. Secure gauze base with non-encircling adhesive tape. Check circulation every 10 minutes (finger warmth/tingling). Loosen if circulation is impaired.

Characteristics of an ideal bandage
  1. Elasticity (moderate): Should stretch but not be overly elastic.

  2. Perforated: Well-ventilated to allow air to reach the wound area.

  3. Cotton Material: For good absorbency.

  4. Sufficient Length: Long enough to provide adequate support or immobilization.

  5. Non-Adhesive: Bandages are applied over dressings, not directly to wounds.

NOTE: Bandages are applied over dressings, not directly on wounds.

General principles of bandaging
  1. Rolled Bandage: Use a tightly rolled bandage of appropriate width. Maintain roll tightness.

  2. Patient Facing: Face the patient when bandaging limbs (except for head bandages).

  3. Bandage Head Position: Hold the bandage head uppermost.

  4. Hand Use: Hold bandage in right hand for left limb, and vice versa.

  5. Bandaging Direction: Bandage from inside outwards and from below upwards, maintaining even pressure.

  6. Start Securely: Begin with a secure turn. Overlap each turn by 2/3 of the previous one.

  7. Tension: Ensure bandage is neither too tight nor too loose.

  8. Finishing: End with a straight turn, fold in the end, and secure, avoiding joints and injury sites.

  9. Fastening: Use safety pins or bandage fasteners.

  10. Tape for Specific Patients: Use tape instead of pins for pediatric or mentally handicapped patients.

General principles of bandaging

Before Applying a Bandage:

  1. (a) Reassurance: Reassure and explain the procedure.

  2. (b) Patient Comfort: Position patient comfortably (lying or sitting), convenient for the first aider.

  3. (c) Support & Elevation: Support the injured part and elevate if needed.

When Applying a Bandage:

  1. (a) Positioning: Stand in front of the patient, except for scalp bandaging.

  2. (b) Passing Bandages: If patient is lying, pass bandages under natural body hollows (ankles, knees, neck, etc.).

  3. (c) Firmness: Apply firmly enough to control bleeding and secure dressings, but not so tight as to restrict circulation.

  4. (d) Expose Extremities: Leave fingers and toes exposed to monitor circulation.

  5. (e) Knot Tying: Use reef knots. Avoid tying over injured parts or bony areas.

When Bandaging for Immobilization:

  1. (a) Padding: Pad between limbs and body or between legs with cloth or folded cotton/towels.

  2. (b) Knot Placement: Tie knots in front of the body or at the midline if sites are injured.

After Bandaging:

  1. (a) Circulation Check: Check circulation every 10 minutes.

  2. (b) Patient Comfort: Ask about discomfort caused by the bandage.

NOTE: Always prioritize infection prevention and control.

Signs of impaired circulation
  1. Extremity Appearance: Pale, cold, later bluish skin (cyanosis).

  2. Sensory Changes: Tingling and numbness.

  3. Movement Limitation: Inability to move the affected limb.

  4. Swelling.

How to check for circulation

Press a fingernail or toenail or skin until it turns pale. Release pressure. Pink color should return quickly. If it remains pale, the bandage is too tight. Loosen it until pink color returns and warmth is felt.

Bandaging Techniques and Patterns
1. Circular Method
  • Each bandage turn completely covers the previous one.

  • Used for ankle bandaging or securing dressings.


2. Spiral Method
  • Each turn partially overlaps the previous one.

  • Applied to straight body parts or those with increasing circumference.

  • Can be used for ear bandaging.


3. Spiral Reverse
  • Bandage is anchored, then reversed direction halfway through each spiral turn.

  • Used for body parts with increasing circumference, like upper arm and leg.


4. Figure of Eight (8)
  • Anchored below a joint, then alternating ascending and descending turns forming a figure 8.

  • Used around joints.


5. Recurrent Method
  • Combines recurrent and circular turns.

  • Hold bandage during recurrent turns, then use circular turns to anchor.

  • Used for scalp and stump bandaging.


6. Triangular Bandaging
  • Used on the shoulder for injuries and clavicle fractures.

  • Can be used as an arm sling, and in emergencies, on any body part.

(a) Arm Sling
  • Supports forearm in slightly raised or horizontal position.

  • For upper arm, wrist, or forearm injuries when elbow can bend.

  • Or to immobilize arm for rib fractures.

  • Procedure:

    1. Support injured arm, hand slightly higher than elbow.

    2. Fold base of bandage to hem.

    3. Place bandage base parallel to body.

    4. Slide upper end under injured arm, around neck to opposite shoulder.

    5. Fold lower end over forearm to meet upper end at shoulder.

    6. Tie reef knot at hollow above clavicle on injured side. Tuck free ends under knot for padding.

    7. Hold point beyond elbow, twist until fabric fits elbow, tuck in, or use safety pin to fasten.

    8. Check finger circulation immediately and every 10 minutes.

(b) Elevation Sling
  • Supports forearm and hand in raised position, fingertips touching shoulder.

  • Controls bleeding from forearm wounds and minimizes swelling.

  • Supports arm in case of hand injury.

  • Management:

    1. Patient places hand across chest, fingers on opposite shoulder.

    2. Place bandage over body, one end over shoulder on injured side.

    3. Hold point just beyond elbow.

    4. Patient extends injured arm slightly from chest while you bring bandage diagonally across back to meet other end at shoulder.

    5. Tie reef knot at hollow above clavicle, tuck ends under knot.

    6. Twist point to fit elbow closely. Tuck in point above elbow and secure.

    7. Check circulation, loosen and reapply if needed.


Haemorrhage (Bleeding)

Definition

  • Haemorrhage: Blood loss from vessels.

  • It can be internal or external, ranging from mild to severe.

  • Mild Haemorrhage: From injured capillaries, slow oozing flow.

  • Severe Haemorrhage: From arteries or veins, forceful blood expulsion due to higher pressure, especially in arteries.


Classifications of Haemorrhage

1. By Time of Occurrence

  • Primary Haemorrhage: Occurs immediately at the time of injury.

  • Reactionary Haemorrhage: Occurs within 24 hours of injury, often as shock resolves and blood pressure rises.

  • Secondary Haemorrhage: Occurs after 48 hours, usually due to infection or sepsis.


2. By Vessel Injured (Source)

  • Arterial Haemorrhage:

    • Arteries carry oxygenated blood from the heart.

    • Blood is bright red, under high pressure, spurting out.

  • Venous Haemorrhage:

    • Veins carry deoxygenated blood back to the heart.

    • Blood is purplish-red, less oxygenated, steady flow.

  • Capillary Bleeding:

    • Smallest vessels.

    • Blood oozes slowly, dark red, most common type.


3. By Site of Injury

  • External Haemorrhage: Bleeding is visible or can be seen.

  • Internal Haemorrhage: Bleeding is hidden or concealed.

    • Internal abdominal bleeding (peritoneal) is dangerous and difficult to stop.

    • Haemoptysis: Blood coughed up from lungs.

    • Haematemesis: Blood vomited from stomach; dark red, coffee-ground like (stomach ulcer).

    • Haematuria: Blood in urine, smoky or blood-stained (kidney/bladder injury).

    • Melaena: Dark, tarry stools (upper intestine bleeding).

    • Fresh, Bright Red Stools: Lower bowel bleeding.

    • Vaginal Bleeding: Menstruation, miscarriage, or injury.

    • Suspect internal bleeding after severe injury or shock without visible blood loss.


Clotting Mechanism

  • Body’s natural process to stop bleeding:

    1. Platelet Aggregation: Platelets gather at injury site, forming a plug.

    2. Clotting Factors: Released, converting fibrinogen (blood protein) to fibrin.

    3. Fibrin Mesh: Fibrin forms a mesh across the vessel cut, trapping platelets and blood cells.

    4. Clot Formation: Mesh shrinks, serum oozes out, leaving solid clot covering the wound.


General Management of Haemorrhage
  • Aim: Stop bleeding quickly and seek medical help.

  • Steps:

    1. Patient Position: Suitable position (sitting or lying) based on injury type/site.

    2. Elevation: Elevate bleeding part, support if not fractured.

    3. Exposure: Expose wound by removing minimal clothing.

    4. Clot Preservation: Do not disturb formed clots.

    5. Foreign Body Removal: Remove visible, easily removable foreign bodies.

    6. Pressure Application: Apply and maintain direct pressure.

    7. Dressing/Bandage: Apply dressing or bandage to secure pressure.

    8. Immobilization: Immobilize injured part.

    9. Hospital Transfer: Transport to hospital ASAP.


Controlling Haemorrhage
  • Principle: Reduce blood flow to wound and promote clotting. Achieved via pressure and elevation.

Direct Pressure

  • Apply pressure directly onto the wound.

  • If foreign body or bone protrusion is present, apply pressure around it for 5-15 minutes.

  • Cover wound with clean cloth if needed.

  • Secure dressing with bandage, firm but not circulation-cutting.

Indirect Pressure

  • Used if direct pressure fails or is impossible.

  • Apply pressure at pressure point between heart and wound on the supplying artery.

  • Prolonged indirect pressure can risk limb viability due to oxygen deprivation.

  • Key Pressure Points:

    • Brachial Artery: Upper limb (arm).

    • Femoral Artery: Lower limb (leg).


Signs and Symptoms of Internal Bleeding
  • History: Recent injury or medical condition.

  • Pain/Tenderness: At affected site, potential swelling.

  • Shock Signs:

    • Pallor (paleness of mucous membranes).

    • Rapid, weak pulse.

    • Shallow breathing.

    • Restlessness.

    • Thirst (if conscious).

    • Low body temperature.

    • Vomiting.

    • Cold extremities.

  • Blood may appear from mouth, eventual unconsciousness.
