Q

Pt presents with narrowing Pulse Pressure (SBP–DBP) list one possible cause

A

Hemorrhage
→ cause SBP to drop & DBP to rise
→ this helps maintain MAP >65 for adequate perfusion

MAP = CO x TPR → DBP + 1/3 (PP)

19
Q

Blunt chest trauma should be considered in patients with what physical exam finding?

A

JVD

20
Q

Best initial test for all blunt chest trauma patients?

A

Chest x-ray

and FAST, ECG, Troponin

21
Q

Pt presents with flail chest injury and begins to have dyspnea with dropping oxygen saturations. What is the next best step in management before bridging pt to surgery for rib fixation with plate?

Flail chest: 3+ ribs are broken in 3+ places creating 1 floating segment

A

Intubate on PPV

1st line: Oxygen, analgesia, and monitoring vitals/pulmonary edema →

If showing signs of impending respiratory failure → Intubate on PPV

2nd line: Once on PPV → surgical rib fracture fixation via Rib cage Plate (sx indicated if rib is very displaced even in the absence of RF)

22
Q

Trauma pt presents has CXR showing Ipsilateral diaphragmatic elevation.
Diagnosis and next best step in management?

A

Phrenic (C3–C5) nerve paralysis → Intubate

*Unilateral paralysis → Asymptomatic/ exertional dyspnea
Bilateral paralysis → severe dyspnea

23
Q

Pulmonary contusion on CXR → Patchy alveolar infiltrates (White out or diffuse opacity)
Next best step in management?

A

Monitor blood gasses (ABG)

*Cx → ARDS

24
Q

Trauma pt presents with:

subcutaneous emphysema w/o tracheal midline shift nor distended neck veins

Next best step in management?

A

CXR

Tracheobronchial injury

25
Q 
Pt  in ED with chest pain, dyspnea
Subcutaneous emphysema
crepitus on chest auscultation synchronous to the heartbeat
\+/- hoarse voice
Dx & next best step in management?

*List 3 possible causes of this presentation?

A
  1. Pneumomediastinum: presence of gas (usually air) in the mediastinum
  2. Get a CXR
  3. Causes:
    Rupture of pulmonary blebs
    Boerhaave (esophageal rupture)
    Iatrogenic (post-procedure: endoscopy)

*(Hamman’s crunch: crepitus w/ heart beat)

26
Q

Pt in ED with recent h/o
Strangulation, intubation, or penetrating trauma to neck or chest
who presents with
Hoarseness, Dyspnea, Hemoptysis, Palpable crepitus, Hamman’s sign (crepitus on chest auscultation)

Diagnosis & Next best step in management?

A

Tracheal Rupture

Chest x-ray → Bronchoscopy→ Chest CT

(if you think it might be Pneumomediastinum the answer is still get a CXR)

27
Q

Tracheal Rupture: Partial or complete puncture or laceration of the trachea or the main bronchi (bronchial disruption)

Management for stable versus unstable patient?

A

In stable patients: conservative management → Neck immobilization.

Unstable patient (vascular injury, hard signs) → Surgery

28
Q

Presents with the all/some of the following:
unequal leg length w/ reduced ROM
Labial/Scrotal, flank, or inguinal hematomas
Urethral injury

A

Pelvic Fractures

(Tilted/ Unstable pelvis)

Diagnostics: Pelvic X-ray → CT (in stabilized patients)

29
Q

Trauma pt with a high-riding or nonpalpable prostate, perineal swelling, & hematuria.
Concerns for ____

A

Urethral injury
( blood at urethral meatus)

*If suspected injury of the urinary tract → Retrograde urethrogram, cystogram, & pyelourethrogram

(Contrast is injected into the ureters to make the ureters & kidneys easily seen on the x-ray)

30
Q

If pt has confirmed urinary injury on imaging what is the next best step in management?

A

Suprapubic catheterization

not transurethral

31
Q

Management of Pelvic Fractures includes:
Prompt ____

If, stable fracture →

If open, unstable fracture, or urological injury →

A

pelvic stabilization with an external binder/brace

Conservative treatment → stable

Surgical treatment → unstable/open/urologic injury

32
Q

Pt with pelvic fracture is hemorrhaging →

Next best step in management?

A

Angiography w/ Embolization

+/- external fixation

33
Q

List 2 possible complications of pelvic fractures:

A

Hemorrhagic shock → intra/retroperitoneal bleeding

Abdominal compartment syndrome → blood filling peritoneal spaces

34
Q

Extremity Pain Worse with passive stretching or extension of muscles
Very tight, wood-like muscles that are extremely tender out of proportion to the extent of injury
Paresthesia & Soft tissue swelling

Diagnosis & Next best step in management?

A

Acute compartment syndrome (ACS)

Bedside fasciotomy

35
Q

Acute limb ischemia presents with what 4 early sxs and what 2 late sxs?

A

Early:
Pain, Pallor, Paresthesias & Poikilothermia (cold)

Late:
Pulselessness & Paralysis

*Pulse is usually still palpable but pulselessness is a very bad sign

36
Q

How to tell apart acute compartment syndrome from acute limb ischemia?

A

ACS: extreme pain worse with passive flexion, rock hard muscles, WARM, swelling

ALI: moderately painful, Pale & COLD

Both: paresthesia & late paralysis
(consider pt hx)

37
Q

____ can turn a simple pneumothorax into a life-threatening tension pneumothorax.

A

Positive pressure ventilation

38
Q

In Penetrating abdominal trauma, surgical repair is done after ___

A

hemodynamic stabilization

IVFs, blood, pressors

39
Q

Can present with cutaneous crepitus (4)

A

Pneumomediastinum/pneumothorax
Tracheobronchial Rupture
Esophageal Rupture
Hemothorax

40
Q

Trauma pt presents with FLAT neck veins, dullness on percussion, Decreased tactile fremitus
+/-Crepitus on palpation
+/-Paradoxical chest wall movement

Diagnosis & Next best step in management?

A

Traumatic hemothorax
(blood within the pleural space)

Get CXR
(Looks like pleural effusion; blunting of the costophrenic angle, tracheal deviation/ mediastinal shift)

*Ultrasound (can detection of smaller amounts of fluid/blood)

41
Q

CXR shows hemothorax what is the next best step in management?

A

Chest tube insertion

42
Q

In Hemothorax a Thoracotomy is indicated if (2)

A

Initial chest tube output is > 1500 mL
or
chest tube output is >200 mL/hour for 2–4 hours

43
Q

What is the main complication associated with Hemothorax

A

Pleural empyema

Thoracentesis
