Question 1

Pulmonary contusion

Answer 1

lung parenchymal bruising (due to transmitted kinetic energy from blunt thoracic trauma) with resulting alveolar hemorrhage and edema. Can occur with or without rib fracture

Question 2

S&S of pulmonary contusion

Answer 2

-<24hrs blunt thoracic trauma -Tachypnea -Hypoxeamia -Decreased breath sounds

Question 3

Diagnostic testing Pulmonary contusion

Answer 3

Most sensitive: Ct. Initial CXR often normalRepeat CXR or CT shows patchy, irregular alveolar infiltrates not restricted by anatomical borders

Question 4

Management of pulmonary contusion

Answer 4

Pain controlPulmonary hygiene (incentive spirometry, chest PT)Respiratory support

Question 5

Atelectasis from blunt thoracic trauma

Answer 5

Pain leads to shallow breathing and lung tissue collapse.CXR: bilateral linear densities in collapsed regions

Question 6

Ddx: ARDS vs pulmonary contusion

Answer 6

ARDS: bilateral alveolar infiltrates, 24-28hrs after trauma Contusion: ipsilateral non-lobular alveolar infiltrates, <24hrs after trauma.

Question 7

Intraperitoneal bladder rupture

Answer 7

Blunt lower abdominal trauma causing full bladder to rupture at its weakest point, the dome.

Question 8

Presentation of intraperitoneal bladder rupture

Answer 8

Inability to voidUrinary ascites Abdominal distention↑ BUN & Cr (peritoneal reabsorption)

Question 9

Diagnosis intraperitoneal bladder rupture

Answer 9

retrograde cystography
