Overview
If the patient presents with a full, bulging abdomen, percussion of the flanks can provide valuable information to diagnose ascites. The presence of shifting dullness has 83% sensibility and 56% specificity to diagnose ascites. A patient without flank dullness has less than 10% chance of having ascites.[1]
Physical Examination
Appearance of the patient
- The patient may appear toxic and in distress because of pain in the abdomen.
Vital Signs
Temperature
- May have increase in temperature due to infection.
- It may decreased if disease progresses to septic shock.
Blood Pressure
- Hypertension can be seen if associated with any heart condition or renal disease.
- Hypotension can be seen in cases of volume loss due diarrhea or severe ascites.
Pulse
- May be normal or increased in rate due to infection.
- It may be low in volume due to dehydration.
Skin
- Skin over abdomen is tense due to ascites.
- Skin changes due to cirrhosis may be seen like spider nevus.
Eyes
- Jaundice may be seen in cases of liver cirrhosis.
- Periorbital puffiness may be noticed in cases of renal failure.
Neck
- Jugular venous distension may be seen in cases of heart failure causing ascites.
Heart
- Signs of heart failure may be seen like S3.
Lungs
- Signs of any infection, or signs of volume overload in lungs due to heart failure.
Abdomen
- Tense and distended abdomen is noticed.
- Tenderness on palpation.
- Shifting dullness on percussion, but it may be painful due to infection.
Neurologic
Following may be noticed when spontaneous bacterial peritonitis complicates or due to underlying liver or renal failure.
