Quickly controlling bleeding from a knife cut is crucial. Follow these steps for effective first aid:
1. Apply Direct Pressure
This is the most important step.
- Find a clean cloth: Use a clean gauze pad, towel, or clean cloth.
- Apply firm pressure: Place the cloth directly over the wound and apply firm, continuous pressure for at least 10 minutes. Don't lift the cloth to check bleeding; adding more cloths is better than lifting. (Sources: Verywell Health, WebMD, Rochester University Medical Center)
- Elevate the injured limb (if applicable): Raising the injured arm or leg above your heart can help slow blood flow. (Source: Cleveland Clinic)
2. Clean the Wound (After Bleeding Stops)
Once the bleeding has significantly slowed or stopped:
- Gently wash: Rinse the wound with cool, clean water. (Sources: Summa Health, Piedmont Healthcare)
- Apply antibiotic ointment (optional): A thin layer of antibiotic ointment can help prevent infection. (Source: MedlinePlus)
3. Bandage the Wound
- Cover the wound: Secure a clean bandage over the cleaned wound to protect it and prevent further bleeding. (Source: Cleveland Clinic)
4. Seek Medical Attention When Necessary
While these steps effectively manage most minor cuts, some situations demand immediate medical attention:
- Severe bleeding: If bleeding is heavy, spurting, or doesn't stop after 10 minutes of direct pressure, seek immediate medical help.
- Deep wound: Deep cuts, wounds that are very long or wide, or wounds that show bone or tendon require professional care.
- Signs of infection: If you see signs of infection (increased pain, swelling, redness, pus), consult a doctor. (Source: Nemours KidsHealth)
Important Note: A tourniquet should only be used as a last resort in cases of severe, life-threatening bleeding from a limb. Improper use can cause serious damage. (Source: Cleveland Clinic)
