Q

when do you not explore a Zone III hematoma in trauma surgery

A

a blunt injury leading to the hematoma should not be explored…instead you do pelvic packing, fix the bones, and IR to embolize what is bleeding

Delta pressure < 20-30 mmHg

23
Q

In what ligament is the splenic artery suspended?

A

splenorenal ligament

24
Q

postsplenectomy hematology picture

A

  • thrombocytosis
25
Q

how much splenic tissue do you need to keep immunocompetence?

A

one third

26
Q

four compartments of the lower leg?

A

anterior
lateral
superficial posterior
deep posterior

27
Q

how do you perform 4 compartment fasciotomy?

A
  • lateral incision: 15-18 cm incision 1 cm posterior to fibular head down to superior of Lateral Malleolus
  • anterior incision 15-18 cm incision 3-4 finger breaths posterior to medial edge of tibia
28
Q

What compartments are decompressed with a medial incision in a four compartment fasciotomy?

A

Superficial posterior

Deep posterior

29
Q

Which compartments are decompressed with a lateral incision in a four compartment fasciotomy?

A

Anterior

Lateral

30
Q

what causes upper airway damage in burn injuries?

A

heat from inhaled air

31
Q

what causes distal airway damage in burn victims?

A

inhaled toxins

32
Q

Cattell-Braasch maneuver

A

Right colon mobilized and rotated medially

33
Q

Maddox maneuver

A

left colon mobilized and rotated medially

34
Q

Best way to evaluate for rectal injury in stable patient? After noticing blood at anus

A

CT scan with rectal contrast

35
Q

Why should you be worried about lateral compression pelvic fractures?

A
  • 25% of them are associated with major arterial blood loss
36
Q

Indication for surgical evacuation for Epidural Hematoma?

A

> 1.5 cm in thickness or midline shift > 5 mm

37
Q

Indication for surgical evacuation for Subdural Hematoma

A

> 1 cm in thickness or > 5 mm midline shift

38
Q

Indication for surgical evacuation for Intraparenchymal hemorrhage

A

large clot causing > 5 mm of midline shift

39
Q

Indication for non-operative management of a fracture?

A
  • non-displaced
  • incomplete fracture
  • impacted fractures in elderly patients or those with osteopenia
40
Q

first line treatment for sub glottis stenosis?

A

serial dilations

41
Q

how would you approach a left subclavian artery injury

A
  • left anterior thoracotomy in 3rd intercostal space (proximal control)
  • transverse incision superior to clavicle for distal control
42
Q

which burns tend to need skin/graft coverage?

A
  • deep 2nd degree
  • 3rd degree
  • 4th degree
43
Q

why do deep 2nd degree burns tend to need graft coverage?

A
  • burn reaches dermal appendages, which prevent repithelialization
44
Q

when can you primarily close a GI injury?

A
  • less than a cm in size

- minimal contamination

how do you repair a tracheal injury?

A

in one layer with absorbable suture and strap muscle to buttress

right renal artery goes posterior or anterior to IVC?

A

posterior

A

Central cord syndrome

51
Q

Bilateral loss of motor, pain and temperature…further down intact vibration and proprioception

A

53
Q

Loss of only proprioception and vibration

A

Posterior cord syndrome
