Multiple Trauma Flashcards
three phases of trauma deaths
immediate, early, late
mortality increases by a factor of what every 30 minutes of elapsed time without care in the severely, multiply injured patient
threefold increase every 30 minutes
roles of orthopaedic surgeon in trauma patient (3)
assess all msk injuries, provide initial bony stabilization, work in concert with trauma surgeons to treat shock and hemorrhage
most common reasons for ineffective ventilation after establishment of an airway (3)
malposition of endotracheal tube, pneumothorax, hemothorax
tension pneumothorax dx (4)
tracheal deviation, unilateral absent breath sounds, tympany, distended neck veins
tension pneumothorax treatment (2)
large-bore needle into second intercostal space midclavicular line, chest tube
open pneumothorax dx (1)
sucking chest wound
open pneumothorax treatment (3)
occlusive dressing (not taped on one side), surgical wound closure, chest tube
flail chest with pulmonary contusion treatment (1)
supportive with endotracheal intubation if necessary
hemothorax treatment (1)
chest tube placement
first step in trauma patient suspected of shock
two large-bore intravenous lines
minimum systolic bp if radial pulse palpable
80 mm Hg
minimum systolic bp if femoral pulse palpable
70 mm Hg
minimum systolic bp if carotid pulse palpable
60 mm Hg
beck’s triad
hypotension, distended neck veins, muffled heart sounds
what level of spinal cord injury causes neurogenic shock
thoracic (sympathetic disruption)
anatomic locations where patients can “bleed out” (4)
chest, abdomen, pelvis, thigh
hemorrhagic shock treatment (2 +/- 3)
aggressive fluid resuscitation, blood replacement +/- angiographic embolization/operative intervention/fracture stabilization
how long does it take to fully cross-match and prepare blood products
~1 hour
how long does it take to get saline cross-matched blood products (minor antibodies)
~10 minutes
universal donor
o negative
important step before delivering blood products
warm the blood
three categories of the glasgow coma scale
eye opening, best motor response, verbal response
radiographic trauma series (3 +/- 1)
lateral c-spine, ap chest, ap pelvis +/- ct scan of these regions
criteria for adequate lateral c-spine x-ray
must see all seven vertebrae and top of t1
clearance of c-spine (2)
adequate normal lateral c-spine +/- followup ct, absence of symptoms or depressed consciousness
positive diagnostic peritoneal lavage (3)
gross blood, bile or fecal material; >100,000 rbc per mL; >500 wbc per mL
percentage of abdominal trauma with genitourinary injury
~15%
next step if genitourinary injury suspected (i.e. high-riding prostate)
retrograde urethrogram
next steps if hematuria present in abdominal trauma patient (3)
voiding urethrogram, cystogram, intravenous pyelogram
