Nonny taught you well.
If there is evidence suggestive of peritoneal irritation, what should we think?
- Appendicitis
- Cholecystitis
If there is evidence suggestive of obstruction or acute vascular compromise, what should we think?
- Aortic Dissection
- Mesenteric Ischemia
This type of pain is described as tension, stretching, ischemia stimulation of specific pain fibers. It is a dull, aching, diffuse, vague (poorly localized) pain felt at the midline in the epigastric, periumbilical or suprapubic areas. Utilizes C type fibers.
Visceral
This type of pain is described by ischemia, inflammation, or stretching stimulation of specific pain fibers. It is generally well-localized and significantly more intense than visceral. A type and C types fibers.
Parietal
This type of pain is described by pain felt at a distance from the affected organ supplied by the same dermatome. It is commonly an aching pain perceived near the surface. It shares the same central afferent pathway with the affected organ.
Referred
This pain fiber is a slow conduction and runs bilaterally and enters the spinal cord at multiple different levels.
Type C
This pain fiber is a rapid conduction that lateralizes to the dorsal root ganglia on the same side and dermatomal level as the origin of the pain.
