49
Q

Management of Tension pneumothorax

A

Life-threatening emergency = ABCDE (A: Immediate needle decompression)

50
Q

Explain the procedure of needle decompression for Tension pneumothorax

A

Use a large bore canulla (14/16G), identify 2nd ICS on the affected side, insert in the anterior midclavicular line

51
Q

Complication of needle decompression and how to proceed

A

Simple pneumothorax -> immediately thereafter, proceed with a tube thoracostomy

52
Q

A

ipsilateral increased ICS, flattened hemidiaphragm, tracheal deviation, displacement of mediastinal structures to contralateral side

53
Q

Possible causes of Tension pneumothorax

Mechanical ventilation and simple pneumothorax with lung injury that fails to seal following penetration, blunt chest trauma, failed central venous cannulation

54
Q

A

Hydropneumothorax

55
Q

Management of Hydropneumothorax

A

56
Q

A

Pleural Effusion

57
Q

Confirmative diagnosis of Pleural Effusion

A

USS guided Thoracocentesis (Transudate/Exudate)

58
Q

Transudate x Exudate

A

Several laboratory tests are helpful in distinguishing transudates from exudates including pH, total protein, lactate dehydrogenase (LD), amylase, glucose, white cell count and differential. Only one of these values has to fall into the exudate range for the effusion to be classified as an exudate. To distinguish exudates from transudates if the patient’s serum total protein is normal and the pleural fluid protein is less than 25g/L the fluid is a transudate. If the pleural fluid protein is greater than 35g/L the fluid is an exudate.

59
Q

Transudates: causes and characteristics

A

Transudates are usually bilateral and arise from either increased capillary hydrostatic pressure or decreased oncotic pressure secondary to congestive heart failure, fluid overload, cirrhosis or hypoalbuminemia.

60
Q

Exudates: causes and characteristics

A

Exudates are usually unilateral and result from increased capillary permeability or decreased lymphatic resorption associated with infection, connective tissue disease, pancreatitis or cancer.

61
Q

Air UNDER hemidiaphragm

A

Pneumoperitoneum = likely due to perforation of duodenal ulcer or abdominal viscus

62
Q

“Rigler´s sign”

A

Double wall sign = Pneumoperitoneum

63
Q

How to check the correct position of the NG tube?

A

CXR + measurement of NG aspirate pH using pH indicator paper (>5.5 is alkaline = RESPIRATORY = incorrect position)

64
Q

Describe the correct position of the NG tube

A

The chest X-ray viewing field should include the upper oesophagus and extend to below the diaphragm: the NG tube should remain in the midline down to the level of the diaphragm, bisect the carina and the tip of the NG tube should be clearly visible and below the left hemidiaphragm (approximately 10 cm beyond the gastro-oesophageal junction and therefore is likely to be within the stomach)

65
Q

Complete white out of one side, pulling the trachea to the abnormal side, contralateral hyperinflation

A

Pneumonectomy (usually due to primary lung cancer)

66
Q

Boot-shaped heart

A

Tetralogy of Fallot (VSD, pulmonary stenosis, displaced aorta, RVH)

67
Q

CXR findings of Tetralogy of Fallot

A

upturned cardiac apex (RVH), pulmonary artery segment concavity (pulmonary stenosis), over-riding aorta (pulmonary stenosis and VSD), oligemia (diminished lung markings)

68
Q

Tetralogy of Fallot: S/S

A

cyanosis; SOB and rapid breathing, especially during feeding or exercise; Loss of consciousness (fainting); Clubbing of fingers and toes; Poor weight gain; Tiring easily during play or exercise; Irritability; Prolonged crying; A heart murmur

69
Q

A

Left upper lobe Pneumonia

73
Q

Ankle swelling + SOB + huge heart on CXR

A

75
Q

“Shmoo sign”

A

Left ventricular enlargement likely due to hypertension (L heart border is displaced leftward, inferiorly with rounding of the cardiac apex)
