Medical Aspects of Primary Blast Injuries (PBI) Information gathered from the following Article: Belanger, H.G., Scott, S.G., Scholten,J., Curtiss, G. Vanderploeg, R.D. (2005). Utility of mechanism-of- injury-based assessment and treatment: Blast Injury Program case illustration. Journal of Rehabilitation Research & Development, 42, 403- 412.
Primary Blast Injuries (PBI) • Blast injuries have increased significantly in modern warfare. • Survival rates of PBI have increased • PBI injuries can be very complex, affecting entire body systems • Cause of PBI “overpressure to gas-containing organ systems, with most frequently injury to the lung, bowel, and inner ear” (p. 403).
Severe Blast Injuries • total-body disruptions are common • Death is very common to those closest to blast injury site • Common injuries include: burn injuries, inhalation injuries, traumatic-limb or partial-limb amputation, traumatic brain injury, and emotional conditions such as emotional shock, posttraumatic stress disorder (PTSD).
Secondary/Tertiary Blast Injury Secondary Blast Injury Fragments from missiles and other debris from Blast injuries are common Can cause head injuries and soft tissue injury Tertiary Blast injury Displacement of entire body is common due to shock waves and dynamic overpressure
Miscellaneous blast-related injuries • Crush injuries are caused by displaced heavy objects and collapsed structures. Example would be a motor vehicle landing on individual due to force of blast. • Soft tissue injuries, bone fractures, and amputations are common
