Questions and Answers
What distinguishes an incision from a laceration?
An incision is a clean cut made by a sharp object, while a laceration is a jagged cut that shows signs of tearing.
What type of bleeding is typically associated with abrasions?
Abrasions usually carry capillary bleeding.

Study Notes
Types of Wounds
- Incision: Clean cut caused by sharp objects; characterized by smooth edges and deep tissue involvement. Typically leads to arterial bleeding.
- Laceration: Jagged cut caused by blunt objects; presents tearing signs and is more prone to infection. Usually results in venous bleeding.
- Abrasion: Superficial injury that removes or bruises the top skin layer; often results in capillary bleeding. Can lead to infection and dehydration if untreated.
- Puncture: Injury inflicted by a sharp object penetrating the skin or tissue; depth and infection risk depend on the object's size and material.
- Avulsion: Skin is torn away while part remains attached like a flap; can be serious depending on the extent of tissue loss.
-
Amputation: Non-surgical removal of a limb or part; classified into three types:
- Guillotine: Clean cut through bone and tissue.
- Crushed: Damage caused by heavy pressure, destroying the tissue.
- Degloving: Removal of tissue and skin from a limb.
- Blast: Extensive tissue destruction due to an explosive force; can severely compromise limb integrity.
Signs and Symptoms of Bleeding (Cyanosis)
- Darkening of lips, ears, and fingertips, indicative of oxygen deficiency.
- Pale appearance of skin.
- Patient may feel weak and dizzy.
- Skin can become moist and cold due to sweating.
- Increased thirst is commonly reported.
- Breathing may become shallow and rapid, suggesting hyperventilation.
- In extreme cases, the patient may exhibit restlessness and excessive talkativeness, indicating critical condition.
Techniques in Controlling Bleeding
-
Apply Pressure: Use gauze to apply direct pressure to the wound for 2-3 minutes.
-
Elevate: Raise the injured area above heart level to reduce blood flow.
-
Calm and Reassure: Provide comfort to the patient while performing care.
-
After initial pressure, check for bleeding; if it persists, add more gauze. If bleeding appears controlled, wrap the injury securely.
-
For severe limb injuries, apply a tourniquet to help control bleeding; record the time of application on the patient’s skin.
-
Hemostatic Dressing: Specialized gauze coated with a chemical that promotes clotting; used for severe injuries and placed inside the wound.
