Primary Impression Traumatic brain injury, severe cortical and subcortical contusions Subarachnoid and subdural hematoma Multiple skull fractures Rule out pulmonary contusion
Trauma Schwartz’s Principles of Surgery , 9thed Definition ….Cellular disruption caused by an exchange with environmental energy that is beyond the body’s resilience…”
Trauma Schwartz’s Principles of Surgery , 9thed • Most common cause of death • 1-44 years old • 3rd most common cause of death regardless of age • Number 1 cause of years of productive life lost
Trauma Merck Manual 2009 Types of Trauma • Blunt – forceful impact • Blow, kick, strike with object, fall, motor vehicle collision, blast • Penetrating – breech of the skin by an object/projectile • Knife, broken glass • Bullet, shrapnel from explosion • Other injuries • Thermal and chemical burns, toxic inhalations or ingestions, and radiation injuries
Traumatic Brain Injury Merck Manual 2009 Also known as acquired brain injury, head injury Occurs when a sudden trauma damages the brain and disrupts normal brain function
Traumatic Brain Injury Medscape, Emedicine • Annual statistics of TBI in the US • At least 1.4 M • 50,000 mortality • 475,000 occur among 0-14yo • 80-90k people experience the onset of a long-term disability
Traumatic Brain Injury Medscape, Emedicine • Leading causes of TBI • Falls – 28% • MVA – 20% • Being struck by or against objects - 19% • Assaults - 11%
Classification Medscape, Emedicine Glasgow coma scale Mild: 13-15 Moderate: 9-12 Severe: 3-8
Classification Medscape, Emedicine Loss of consciousness
Pathophysiology Medscape, Emedicine Primary Injury Induced by mechanical force and occurs at the moment of injury Secondary Injury Occurs hours or days after the inciting trauma
Pathophysiology Medscape, Emedicine/ Merck Manual 2009 Primary Injury • Contact • Scalp injury • Skull fracture • Surface contusion • Acceleration-deceleration • Shear, tensile, compressive strains • Coup and countercoup
Pathophysiology Medscape, Emedicine/ Merck Manual 2009 Primary Injury • Contusion – distinct areas of swollen brain tissue • poles and inferior aspects of the Frontal lobes • Cortex above and below the operculum of the sylvian fissures • Lateral and inferior aspects of the temporal lobes
Pathophysiology Medscape, Emedicine/ Merck Manual 2009 Primary Injury • Intracranial hematoma – most common cause of death and deterioration after TBI • Epidural – temporal bone fracture and MMA rupture • Subdural – rupture of bridging veins in the subdural space • Sub arachnoid – damage to blood vessels in the posterior fossa stalk
Pathophysiology Medscape, Emedicine/ Merck Manual 2009 Primary Injury • Intracranial hematoma – most common cause of death and deterioration after TBI • Diffuse axonal injury – rotational acceleration of the brain • Defined clinically as LOC lasting > 6 hours in the absence of a specific focal lesion
Pathophysiology Cellular destruction! Local edema Failure of ion pumps Intracellular Ca and Na overload hemorrhage Increased ICP Medscape, Emedicine/ Merck Manual 2009 • Secondary Injury • impairment or local declines in cerebral blood flow
Pathophysiology Neuronal death!!! Free radical formation Release of excitatory amino acids Cells Die Proteolysis Lipid peroxidation Medscape, Emedicine/ Merck Manual 2009 • Secondary Injury • impairment or local declines in cerebral blood flow
