In ballistic trauma, what is the primary difference between temporary and permanent cavitation?
In ballistic trauma, what is the primary difference between temporary and permanent cavitation?
- Temporary cavitation only occurs with low-velocity projectiles.
- Permanent cavitation refers to stretching of the tissue, while temporary cavitation involves the crushing of tissue.
- Temporary cavitation involves the stretching of tissues due to the energy of the projectile, while Permanent cavitation is the residual cavity after the projectile has passed. (correct)
- Permanent cavitation is easily reversible with medical intervention.

Study Notes
- Penetrating trauma involves injuries from:
- Gunshot wounds (GSW)
- Stab wounds (edged weapons)
- Impalement
- Explosive projectiles (blast injuries)
Penetrating Force of Bullets
- Different bullet types have varying penetration depths in tissue:
- .22 LR: 6-12 inches
- 9mm FMJ: 12-18 inches
- .45 ACP: 10-14 inches
- 5.56mm: 12-18 inches (fragmentation may occur)
- 7.62mm: 16-24 inches
- .50 BMG: Can penetrate through the body
Ballistic Trauma
- Ballistic trauma involves temporary and permanent cavitation.
Shotgun Injuries
- Shotgun injuries can result in multiple penetrating wounds.
- Projectiles travel at 490m/sec
- Can exert forces of 200kg
Edged Weapons
- Stab wounds can be life-threatening.
Explosive Trauma
- Explosive trauma involves:
- Pressure waves
- Blast winds
- Flame front
Blast Trauma
- Blast trauma can result in
- Barotrauma (blast lung/eye-ear injury)
- Secondary penetrating injuries (primary/secondary fragments/amputations)
- Tertiary blunt injuries (fractures/concussion/crush)
- Quaternary burns/gas
Open Pneumothorax
- Open Pneumothorax is a "sucking chest wound"
- Air drawn through wound, resulting in negative pressure
- Air expelled on expiration increases intrathoracic pressure
- Lung in hemithorax remains collapsed due to the air being drawn into the chest.
Summary of Penetrating Trauma
- Initial assessment of the trauma patient needs to be comprehensive, systematic, and expedient.
- It is important to be aware of distractions, negative assumptions, and false assurances.
- Actions should be practiced so they are automatic.
- Decisions should focus on choosing the right course of action.
