Move down inferiorly, usually dull sounds of liver disapears at the right costal margin which indicates end of liver in normal person

53
Q

Explain how to palpate the spleen

A

Start at right iliac fossa region with right hand feeling,

Palpate towards the left costal margin

Use the left hand to full the rib and spleen towards ur right hand for palpation

54
Q

Explain how to precuss the spleen

A

Percussion will. be along the left anterior axillary line starting at 10th intercostal space (between 10th and floating rib 11)

You will percuss for both inspiration and expiration going downwards

55
Q

What type of percussion sound indicates splenomegaly?

A

Percussion becomes dull on full inspiration

56
Q

A
62
Q

What is the coronal plane?

A
63
Q

What plane is this CT scan showing?

A

Sagittal plane

64
Q

What plane is this CT scan showing?

A

Coronal CT scan

65
Q

What plane is this CT scan showing?

A

Transverse

66
Q

How can you tell the difference between an MRI and CT scan?

A

CT scan shows bones as white and fat/water as black

MRI shows bones as black and fat/water as white

(Left is CT, right is MRI)

67

A

Between ASIS and pubic tubercle

A

Posterior rami of thoracic spinal nerves

75
Q

Memorise dermatome

A
76
Q

Which part of the nervous system is responsible for innervation of abdominopelvic visceral organs?

A

Autonomic nervous system

77
Q

Afferant pain fibres from abdomino-pelvic visceral organs exits alongisde sympathetic nerves within which spinal levels?

A

T1-L2

78
Q

How does the umbillicus tend to look in obese patients?

A

Sunken umbilicus

79
Q

If ever you do feel the livers edge in an unhealthy patient. What findings must you record?

A

Surface smooth or irregular?

Surface hard or soft?

Is there tenderness (pain)

Is there any pulsations?

80
Q

The distance between the upper and lower limits of the liver is usually how many centimetres in a healthy adult?

A

Around 13cm

81
Q

The spleen, when affected by disease, usually enlarges towards what direction of the abdomen

A

Enlarges from left costal margin, across the umbillicus and towards the right iliac fossa

(Hence why you start palpation from the right iliac fossa)

82
Q

How can an enlarged spleen be identified over an enlarged kidney?

A

During splenic enlargement, its sharp upper border with a characteristic notch will be the leading edge of the organ which your palpating finger will encounter

83
Q

What are the five causes of a distended abdomen?

A

Fluid (ascites)

Fat

Faces (Bowel obstrucion)

Fetus

Flatus

84
Q

List the 4 most common causes of ascites (Excessive fluid in peritoneal cavity)

A

Hepatic cirrhosis

Portal hypertension

Liver malignancy

Peritoneal malignancy

85
Q

List 8 less common causes of ascites

A

Cardiac failure

Peritonitis

Malnutrition

Hypoproteinaemia

Pancreatitis

Lmphatic obstruction

Hypothyroidism

Renal dialysis.

86
Q

What does normal percussion of the abdomen sound and how does this change for patients with ascites?

A

Normal percussion will have a resonant sound due to gas in the bowels

Patients with ascites will have a dull sounds (starting intitally in the flanks) the more fluid, the more dullness will extend towards the midline of the abdomen.

87
Q

Explain how you would assess for shifting dullness

A

Lay patient in supine position

Begin percussing from the midline out to the flanks on both sides

If fluid (dull sounds) is detected on a patients flank, you will ask the patient to lie on their side and wait for 30 seconds (for fluid to drain to opposite side)

Percuss the same area that was intially dull and observe for a now resonant sound.

If the sound is now resonant, this is known as shifting dullness and indicates ascites.

Remember to repet this on the opposite flank

88
Q

If the abdomen is severely distended and the abdominal percussions is dull throughout, even after testing for shifting dullness, what test should be performed to determine if the reason for dullness is due to ascites?

A

Fluid thrill test

89
Q

Explain how you would perform a fluid thrill test

A

place the palm of your left hand over the left side of patient’s abdomen

flick a finger of your right hand on the right side of the abdomen.

If you feel a ripple against your left hand, a fluid thrill is present.

90
Q

Name the point which can be palpated to assess for appendicitis

A

McBurney’s point

2cm from ASIS towards the umbillicus
