TNCC Burn and Surface Trauma 2025
Adult fluid replacement for ELECTRICAL burns - ANS4mL/kg
Note that this is different from standard fluid replacement for burns (wt x 2mL x %
TBSA)
carbon monoxide poisoning - ANSCO replaces oxygen and hemoglobin creating
carboxyhemoglobin
s/s headache, confusion, nausea or vomiting
half-life of CO is about one hour on 100% oxygen
Treat with oxygen until carboxyhemoglobin levels drop to less than 10% (ABG)
Frostbite treatment - ANSRewarm area over 15 to 30 minutes in controlled temperature
water (98.6-102.2)
Give pain medicine
Avoid friction or rubbing
Myoglobinuria Treatment - ANSSodium bicarb infusion to alkalize urine (promoting
excretion of myoglobin)
Prevent oliguria
Normalize serum electrolytes
Decompress any areas with compartment syndrome
Pediatric or less than 40 kg burn fluid replacement formula - ANS3 mL/kg per % TBSA
in addition infants and children weighing less than 30 kg should be placed on a glucose
containing maintenance fluid, specifically D5 LR.
"yaw" of a projectile - ANSability to move up and down
acceleration forces - ANSsudden and rapid onset of motion
ex: parked car hit by a high speed vehicle
another form of mechanical energy with compression forces - ANShanging,
strangulation, or compression asphyxia (chemical)
Biomechanics - ANSgeneral study of forces and their effects on living tissue & the
human body
cavitation - ANSseparation of tissue resulting from a sound and/or hydraulic wave force
can cause crushing/tearing/shearing forces
Chemical energy - ANSheat energy transfer from active chemical substances such as
chlorine, drain cleaner, acids, or plants

common mechanisms of blunt trauma - ANS1. Fall

  1. MVC
  2. Bike collisions
  3. Peds struck
  4. Assualts compression forces - ANSexternal force applied at time of impact ex: stationary objects (dashboard or steering wheels that push into someone) objects in motion (bullets/stabbing instruments/bats & balls/fits and feet) blast forces compression strength - ANStissue's ability to resist crush force deceleration forces - ANSsudden stop in the body's motion ex: falls/collisions difference in pedestrian struck (adult vs peds) - ANSadults commonly have lateral or posterior impacts as they try to turn away while peds usually turn toward the car causing anterior impact down & under injuries - ANSlower extremity & pelvis fractures drowning is what kind of energy? - ANSmechanical energy forces are involved when water enters the lungs and shearing force cause the lungs to expand and bleed dry drowning - ANSresult of spasm of the larynx when water enters the throat, this causes a mechanical airway obstruction and altered hemodynamics or blood flow dynamic pressure - ANSmuch like a gust of wind, this can carry with it fragments and debris Electrical energy - ANSlight socket/power lines/lightening energy transfers & injuries FALLS - ANS1. point of impact determines major point of energy transfer
  5. type of surface that is hit (extent the surface can absorb energy)
  6. tissues ability to resist
  7. pushing increases acceleration example of compression injuries - ANSwhen the organs are crushed from surrounding internal organs or structures (seatbelts - > compress small bowel or lumbar spine) example of high/medium velocity - ANSfirearms medium - > handgun/shotgun large - > long gun (rifles)

laceration acute renal failure due to rhabdo hypotension hypovolemia explosive related injuries - respiratory - ANSblast lung hemothorax pneumothorax pulmonary contusion and hemorrhage AV Fistulas Airway epithelial damage Aspiration pneumonitis Sepsis extent of injuries from an assault are dependent on (7) - ANS1. amount of force

  1. distance the force travels
  2. object used to deliver the force
  3. type of tissue receiving the force and the ability to resist or absorb the stress
  4. speed or velocity of the force
  5. trajectory of the force
  6. presence of penetrating trauma external forces - ANSdeceleration acceleration compression head on impact - ANSejects the rider forward with the head and torso leading the way; lower extremities can collide with the handlebars head on impact injuries - ANSfemur/pelvic fractures head neck chest extremities high-side crash - ANSmotorcycle begins to crash to the low-side but then grabs traction and flips over catapulting the rider into the air injuries from penetrating mechanisms are dependent on two variables: - ANS1. point of impact
  7. velocity of impact KE= - ANS1/2 mass * velocity squared Kinematics - ANSstudy of energy transfer as it applies to identifying actual or potential injuries

kinetic - ANSmotion Lateral impacts are associated with what kind of injuries? - ANSshear injuries to the aorta fracture of the side clavicle lateral pelvic & abdominal injury lateral head & neck injury lateral or angular impacts - ANSmay initially crush the lower extremities but will likely cause the motorcycle to rapidly impact the ground, resulting in upper extremity, lateral head, & neck injuries Law of conservation of energy - ANSenergy can neither be created nor destroyed, BUT it can change form low-side & high-side crash injuries - ANSabrasions shoulder & clavicle injuries lateral head lower extremity low-side crash - ANS"laying the bike down" witht eh tires leading in the direction of travel Mechanical energy - ANSfrom one object to another MOI - ANShow injuries occur as a result of how external energy forces in the environment are transferred to the body MOI on motorcycle - ANS1. low-side crash

  1. high-side crash
  2. head-on impacts
  3. lateral or angular impacts MVC impact sequence - ANSfirst impact: vehicle hits object second impact: vehicle occupant collides with interior third impact: internal structures collide within body cavity Newton's 3rd Law - ANSfor every action, there is an equal & opposite reaction Newton's First Law - ANSa body at rest will remain at rest, a body in motion will stay in motion Newton's Second Law of Motion - ANSForce = Mass * Acceleration overpressure - ANSoccurs when the victim is enveloped on all sides with crush forces

tertiary blast injuries - ANSimpacts with larger objects propelled by the blast wind resulting in blunt trauma -- can result in pelvic or femur fractures or major thoracic injuries such as aortic & great vessel rupture the haddon matrix - ANSpre-event (host, agent, physical environment, socioeconomic environment) event (host, agent, physical environment, socioeconomic environment) post-event (host, agent, physical environment, socioeconomic environment) Thermal energy - ANStransfer of heat from the environment to the host to heavier objects require more or less force to more them? - ANSMORE True or false: Higher mass or greater speed results in greater energy - ANStrue two components of blast waves - ANSoverpressure dynamic pressure two primary injury patterns in frontal collision - ANS1. "up & over" the steering wheel or dashboard - head & chest lead the way (more likely with no seatbelt)

  1. "down & under" up and over injuries - ANShead neck check abdomen Waddell Triad - ANSpediatric patient involved in a pedestrian struck will have three injuries:
  2. head
  3. thorax
  4. lower exremity what helps a tissue against compression/shear forces - ANSmuscle density surrounding bone what helps a tissue's tensile strength - ANSstrength of opposing msucles what increases the probability of fatal injury? - ANSejection from the vehicle what kind of organ tolerates pressure-wave energy better? - ANSsolid organs what kind of organ tolerates shear forces better? - ANSair-filled organs what kind of tissue have a greater propensity for wear & tears in high velocity cavitation
  • ANSsolid organs (liver)

what kind of tissue tolerates high velocity cavitation - ANSair filled organs (lungs or stomach) what usually has more impact in a trauma? Speed or distance? - ANSDistance --> the greater the distance, the less impact when is a fall considered significant in the PEDS population - ANS>than 3x the height when mass is doubled, what happens to the energy? - ANSit also doubles when velocity is doubled, what happens to the energy? - ANSit quadruples where is the tissue in reference to the point of impact that is affected by the maximum amount of energy from the obect striking the tissue or maximal energy? - ANStissue most proximal
