Can Improvised Sutures Be Effective for Closing Wilderness Wounds?

Choosing the Right Materials

When improvising sutures, it’s essential to select materials that are strong, durable, and easy to work with. Some viable options include:

• Fishing line or thin wire (monofilament or nylon)
• Twine or cordage (natural or synthetic)
• Waxed dental floss
• Thread from clothing or fabric

The ideal material should be roughly 0.5-1.5 mm in diameter, as this will provide the necessary strength for wound closure without causing excessive tissue damage.

Preparing the Wound for Closure

Before attempting to close the wound with improvised sutures, it’s crucial to properly clean and prepare the area. This involves:

• Rinsing the wound with clean water to remove debris and bacteria
• Applying a topical antibiotic ointment to reduce the risk of infection
• Using a clean gauze or cloth to dry the area
• Considering the administration of a broad-spectrum antibiotic to prevent infection

Once the wound is prepared, the improvised sutures can be applied using a simple interrupted stitch or a running stitch.

Techniques for Applying Improvised Sutures

When applying improvised sutures, it’s essential to maintain asepsis and work carefully to avoid causing further tissue damage. The following techniques can be employed:

• Using a needle made from a sharp stick or a metal skewer to create holes for the suture material
• Tying knots at the end of each suture to secure them in place
• Leaving a small amount of slack between sutures to allow for tissue movement and prevent tension on the wound
• Re-checking the wound regularly to ensure it is healing properly and adjusting the sutures as necessary
