Midterm Flashcards
What is the key thing that causes abdominal discomfort?
rapid distension of hollow organ smooth muscle
What is the most sensitive structure in the abdomen (pain threshold)?
parietal peritoneum
What is the least sensitive structure in the abdomen (pain threshold)?
parenchymatous organs
Where is visceral pain often first noticed? (location on abdomen)
closer to midline of abdomen
Is visceral pain made worse by palpation?
no
Is visceral pain made worse by movement/coughing/breathing deeply?
no
Is the underlying musculature tense/painful with visceral pain?
NO
Is visceral pain easily localized?
No (V for visceral, V for vague)
Three potential sources for localized abdominal pain?
- peritonitis 2. nerve root/intercostal pain 3. MFTPs
What might a pt have if they complain of pain localized to the abdominal wall, or a diffuse discomfort that mimics visceral pain?
MFTPs
Why do pts not realize the area of tenderness is extremely localized and superficial with MFTPs?
They are preoccupied with the large area of pain spread
Where does peritoneal pain usually manifest? (location on abdomen)
dermatomes T5-L2
Is peritoneal pain easy to localize?
Yes
Is peritoneal pain made worse by movement/coughing/deep respiration?
Yes
Is peritoneal pain made worse by palpation?
yes
What can peritoneal irritation lead to? (muscles)
reflexive contraction of segmental msls
If visceral pain changes location and starts becoming parietal pain and you can’t find evidence of an NMS condition or MFTP as the source of pain, what should you start to think about?
peritonitis
What is Dunphy’s sign?
localized pain that increases with coughing
What is the “jar test”?
sudden vibration increases/localizes the pain
What position must the pts knees be in to begin abdominal exam?
pt supine, hips and knees flexed
What represents the first physical contact with the pt’s abdomen?
auscultation
Do abdominal bruits assist in the Dx of AAA?
No
What kind of bruits are more sensitive for renal vascular dz?
anterior bruits near the umbilicus
what kind of bruits are more specific for renal vascular dz
flank bruits
