Study Notes

Patient and Wound Evaluation

Gather patient history, including medication, allergies, and tetanus status.
Evaluate wound characteristics: mechanism of injury, timing, and environment.
Assess estimated blood loss and functional ability (sensation/movement).
Check for additional injuries or possible foreign bodies (metal, wood, glass).

Choosing Materials for Closure

Use appropriate suturing material based on wound type and characteristics.
Types of sutures include nylon, polypropylene, polyglactin, polydioxylene, silk, and chromic gut.
Staples offer quick closure but are typically used for scalp wounds in ER settings.
Adhesive skin glue (e.g., Dermabond) can be effective for clean, non-bleeding wounds.

Suture Selection Guidelines

Monofilament synthetic non-absorbable sutures (sizes 3.0 - 6.0) preferred for most lacerations.
Absorbable sutures (e.g., polyglactin, gut) are used for deeper or intra-oral lacerations.
Consider suture needles: tapered (for smoother skin) vs. cutting (for more tension and strength).

Anesthetic Choices

1% Lidocaine is standard, with or without epinephrine for hemostasis and prolonged effect.
Maximum dosages vary by weight; consider patient health conditions before use.
Digital nerve blocks can be used for finger lacerations, with bupivacaine for longer action.

Preparing the Wound

Irrigation is crucial for infection prevention; should be thorough and done prior to closure.
Use sterile saline for wound cleaning; do not reuse saline bottles between patients.
Skin preparation should avoid contact with the wound and ensure agent is washed away.

Suturing Technique

Suture placement must be at a 90-degree angle for proper closure.
Approximate wound edges, maintain equal spacing, and use symmetrical stitches.
Secure knots to the side and ensure the suture's bite is consistent with wound depth.

Common Stitch Types

Simple interrupted, running, and mattress stitches each have specific applications.
Subcuticular stitches avoid visible scarring and are suitable for clean wounds.
Everted edges are crucial for optimal healing and preventing inward scar contraction.

Post-Procedure Care

Keep the wound dry and covered for initial 24 hours; observe for signs of infection.
Wound rechecks are essential for dirty wounds within 48 hours; clean with soap and water.
Provide detailed follow-up instructions based on wound type and healing progress.

Tetanus Prophylaxis Guidelines

Tetanus shots recommended based on wound type and patient immunization history.
Tetanus-prone wounds require attention if the patient hasn’t been vaccinated within 5-10 years depending on wound characteristics.

Documentation

Thorough documentation of encounters and procedures is critical for medical records.
Include all relevant details such as injury mechanism, wound assessment, and chosen treatment method.
Record patient consent, demographics, risks, and follow-up care instructions clearly.
