  • 25% associated with malignancy
  • MUST distinguish b/t transudate and exudate
61
Q

transudate pleural effusions

A

transudative contains fluid

  • results from increased hydrostatic pressure pushing fluid out of vessels (e.g. heart failure) and/or decreased osmotic pressure pulling fluid in due to decrease proteins within vessels (dec. protein synthesis in liver disease or inc. protein loss in kidney disease)
  • INTACT capillaries
62
Q

exudative pleural effusions

A

exudative contains fluid and protein

  • inflammation causes vasodilation and stasis of fluid in vessels as well as increased inter endothelial spaces (so protein leak out)
  • related to an inflammatory process (e.g. malignancy)
  • LEAKY capillaries
63
Q

pleural effusions - 5 types

A
  1. exudates: malignancy, infection, trauma, PE

  2. transudate: CHF, atelectasis, renal/liver dz
    - bilateral
  3. empyema: direct infection of exudate
  4. hemothorax: trauma
  5. chylothorax: TB
64
Q

66
Q

pleural effusion - role of imaging

A

Imaging: helps to define size

CXR can detect as little as 50mls

  • lateral decubitus for free flowing v. loculated
  • upright (blunting of costophrenic sulcus)

CT can detect as little as 10mls

67
Q

pleural effusion - tx

A

transudates

  • correct underlying condition
  • therapeutic thoracentesis if dyspnea

exudates

  • drain empyemas
  • pleurodesis (prevents fluid build-up) for malignency
68
Q

pleural effusion - how to distinguish transudate vs. exudate

A

Light’s criteria:

  • compares amount of protein or LDH in the fluid vs. serum
  • higher than normal protein or LDH in pleural fluid compared to serum are signs of exudate (infection/inflammatory process)
69
Q

lactate dehydrogenase (LDH)

A

LDH is an enzyme found in almost every cell of your body

When cells are damaged or destroyed, this enzyme is released

70
Q

  • if high clinical suspicion, cannot be used to r/o PE and further imaging (CT) must be used
82

Q

pulmonary hypertension - dx

A

multifactorial

  • CXR/CT: inc. vasculature
  • PFTs: lung pathology
  • ECHO/TTE: RVH, pulm. artery pressure
  • catheterization: determine degree of HTN
90
Q

pulmonary hypertension - tx

A

treat underlying cause (e.g. oxygen for COPD, anticoags for emboli, diuretics or salt restriction for for pulmonale)

vasodilators: CCBs, epoprostenol (PGI2), prostacyclin

91
Q

cor pulmonale - definition

A

failure of rt side of heart caused by prolonged high blood pressure in the pulmonary arteries (pulmonary HTN) and rt ventricle of the heart

rt ventricular enlargement leads to rt ventricular failure

92
Q

cor pulmonale - cause

A

acute: think PE
chronic: think COPD

pulmonary vascular dz: 
 - PE, vasculitis, ARDS
respiratory disease:
 - obstructive (asthma, COPD)
 - restrictive (ILD, lung resection)
93
Q

cor pulmonale - clinical findings

A

fatigue, exertional dyspnea, syncope w/ exertion

inc. chest diameter

labored resp effort w/ retractions

hyper-resonance to percussion
- diminished breath sounds, wheezing, distant heart sounds, cyanosis

94
Q

cor pulmonale - dx and tx

A

Dx:

  • CXR
  • ECG: RAD > 30, inverted t waves in RV precordial leads

Tx:

  • oxygen
  • dec. pulm vasc. resistance and pulm. HTN
  • treat underlying disorder
95
Q

Acute Respiratory Distress Syndrome (ARDS) - definition

A

acute (12-18 hrs) hyperemic respiratory failure after systemic or pulmonary insult W/O heart failure

96
Q

Acute Respiratory Distress Syndrome (ARDS) - cause

A

sepsis: MOST COMMON
others: toxic inhalation, near drowning, aspiration

97
Q

Acute Respiratory Distress Syndrome (ARDS) - clinical findings

A

respiratory distress, tachypnea, fever, crackles, rhonchi

98
Q

Acute Respiratory Distress Syndrome (ARDS) - CXR, Dx, and Tx

A

CXR: diffuse pulmonary infiltrates that SPARES costophrenic angles
- normal heart size (NOT related to HF)

Dx: clinical

Tx: underlying cause plus supportive care
- high mortality rate!

99
Q

ground glass opacities on CXR

A

indicates exudative or transudative fluid in lungs

- lines apparent in CXR
