Causes of shock (4)
- Hemorrhage
- Tension pneumothorax
- Cardiac tamponade
- Neurogenic shock
- High spinal cord injury
- Decreased total peripheral resistance
- suspect after ruling out other three
- Vasopressors and increased TPR
ABCDE
Airway Breathing Circulation Deformities Exposure
Previously stable chest trauma becomes rapidly unstable suspect
Air embolism
New diastolic murmur in chest trauma suggests
Aortic dissection
Massive air leak in chest tube
Suggest tracheobronchial injury
Chest injury between nipples order
Echo for heart
CTA for aorta and its branches
Bronchoscopy for upper airways
Esophagograph/ esophagogram for esophagus
Gun shot wounds that require immediate laparotomy
Gun shot wounds below nipple (fourth intercostal space)
Separate body part what to do
Place in gauze moistened with saline
Sealed inside a plastic bag
Place on ice
Tx Increase cranial pressure
Head elevation
Hyperventilation
IV mannitol
Epidural hematuria due to what vessel
Middle meningeal artery
Subdural hematuria due to what vessel
Briding beins
Respiratory compromise in flail chest
Due to pulmonary contusion rather than flail chest
Tx Flail chest
Pain control
Positive pressure
Fixed in severe cases
Blunt trauma to first rib, scapula or sternum
Think strong bones
Associated with aortic disruption
What tests to do with pelvic fracture
Rectal exam Proctoscopy Retrograde cystogram for bladder Retrograde urethrogram Pelvic exam for vagina in women
Most common injury with blunt abdominal trauma
Spleen
Fractured left ribs 9-11
Spleen
If ruptured remove and give Pneumococcal and HiB and meningococcal vaccine)
Right lower rib fractures
Liver trauma
Child falls on handle bars
Epigastric pain
Bilious vomiting
Retroperitoneal air on X ray
Duodenum injury
Diaphragm ruptures on
Left side (since liver protects right)
Tx Pelvic fracture
External pelvic binders and angiographic embolization
Acute abdominal pain with blood in rectum
Mesenteric ischemia
McBurneys point
Appendicitis
Appendicitis tx
IV antibiotics
- cefoxitin
- cefazolin
plus metronidazole
Chemical burns
Copiously irrigation for 20-30 minutes before transferring to hospital
Complications of electrical burns
Rhabdomyolysis
Compartment syndrome
Thrombosis of blood vessels —> limb ischemia
Arrhythmias
Infection in burns caused by
Pseudomonas or Gram + occi
Abdominal pain
Rigid to palpation
Free air on Xray
Surgical exploration
Perforation
Formula for fluids
First 24 hours
4 x patient’s weight in kg x % BSA
body surface area
Give 50% of fluids over first 8 hours and remaining 50% over following 16 hrs
Measuring body percentage
Entire head 9%
Anterior torso 9%
Upper back 9%
Entire arm 9%
Anterior abdomen 9%
Lower back 9%
[Abdomen in total 36%]
Perineum 1%
Entire leg 18%
Head 9% Torso 36% Arm 9% Perineum 1% Leg 18%
Burns what to use topically
Topical antimicrobials if no epidermis intact
Mafenide acetate (fulfamylon)
Silver sulfadiazine
Hypotension and vasopressors
Only give vasopressors once adequate fluid resuscitation
Cause vaso constriction of extremities and digital ischemia
Fever POD 1-3
Atelectasis
Pneumonia (day 3)
Fever POD 3-4
UTI
Fever POD 4-5
DVT
PE
Fever POD 7+
Surgical site infection
Pulseless electrical activity tx
CPR
Epinephrine
Vasopressin
Ventricular fibrillation tx or pulseless ventricular tachycardia
CPR
Defibrillate —> Defibrillate —> Epinephrine —> Defibrillate —> Amiodarone —> Defibrillate —> Epinephrine
Tx Supraventricular tachycardia
Unstable —> synchronized electrical cardiovesion
Stable —> vagal maneuvers
If resistant= adenosine
