In medicine, reflexes are often used to assess the health of the nervous system. Doctors will typically grade the activity of a reflex on a scale from 0 to 4. While 2+ is considered normal, some healthy individuals are hypo-reflexive and register all reflexes at 1+, while others are hyper-reflexive and register all ref...

In medicine, shifting dullness refers to a sign elicited on physical examination for ascites (fluid in the peritoneal cavity). The test is performed by first percussing the midline of the abdomen to elicit a resonant note due to gas in the abdomen. If there is no area of resonance, then the test cannot be performed. Pe...
Shifting dullness
c_yemzgbcm74qr
The examiner's index finger remains on the resonant side, and the middle finger remains on the dull side, straddling the fluid-air level. The patient is then asked to lean on their right lateral side (assuming the examiner used the traditional right-sided approach). This stabilises the patient by positioning them betwe...
Shifting dullness
c_j8hiqgi3gvt5
It is imperative that the examiner's fingers stay in the same position. After waiting sufficient time for any fluid to shift (up to 30 seconds), the dull position is then percussed. It may now be resonant.
Shifting dullness
c_ldjvrzzvhi5u
The percussion may now be performed down the anterior side until a new dullness is found. To confirm a positive result it is recommended that the now resonant area become dull again when the patient is back in the supine position. If the borders between tympanitic (resonant) and dull notes remain the same, the person p...
Shifting dullness
c_3xe7i4paa8vo
If the fluid causing the dullness was not free, then the air-fluid level would not move. Shifting dullness is usually present if the volume of ascitic fluid is up to 500 mL ml. If low volume ascites is suspected, then an attempt to elicit the puddle sign may be performed.
