Penetrating Injuries for Certified Emergency Nursing (CEN)
Included In This Lesson
Outline
Penetrating Injuries
Definition/Etiology:
- Penetrating injuries from guns, industrial accidents, paint guns, and nail guns
- Appearance of entrance wound does not always reflect the amount of damage beneath
- Do not remove impaling objects
Pathophysiology:
- Firearm injuries can result in extensive damage to underlying tissues and organs
- Fragments from shattered bones can form secondary projectiles
- Passage of the bullet in a gunshot wound (GSW) forms a negative pressure cavity that pulls debris into the wound
- Shock waves travel through tissues, causing shearing and crushing of nerves, vessels, muscles, and organs
- Bullets from rifles have a higher velocity than those from handguns and are associated with greater tissue damage
- High-pressure injuries such as from paint guns or grease guns that are designed to inject these substances into hard-to-reach places
- When forced against the skin, such guns inject paint or grease for several centimeters, typically following tissue plane
- In the volar aspect of the hand, paint or grease can travel down tendon sheaths and along the digits
Collaborative Management:
Interventions:
- ABCs – High-flow supplemental oxygen, bleeding control, frequent vital signs/monitoring
- IV x2
- IVF resuscitation, antibiotics, tetanus
- Projectile path unpredictable, wound evaluation (location, number)
- Preserve forensic evidence
- Surgical vs. nonsurgical
Linchpins: (Key Points)
- Penetrating injuries from guns, industrial accidents, paint guns, and nail guns
- Do not remove impaling objects
- Determine type of projectile, potential for multiple internal injuries, may be more than one projectile (how many shots?)
