visceral pain
poorly localized, gradual onset
visceral pain

epigastric area
midgut pain localizes to
periumbilical area
hindgut pain localizes to
suprapubic area
what type of secondary autonomic effects accompany visceral pain?
sweating, nausea, vomiting, restlessness, pallor
mediated by alpha gamma fibers that are distributed to skin and muscle
somatic-parietal pain
sharp, stabbing, well localized
somatic parietal pain
why is lateralization of parietal pain possible?
only one side of the nervous system innervates that part of the parietal peritoneum
diaphragmatic irritation from a subphrenic hematoma or splenic rupture perceived as shoulder pain
Kehr’s sign
PMH of cardiovascular disease may raise suspicion for
mesenteric ischemia
patient lying still in bed, fetal position, reluctant to move, appears distressed
peritonitis
bluish periumbilical discoloration indicates
intrabdominal bleeding
high pitched tinkling bowel sounds may indicate
early bowel obstruction
intestinal fluid and air under pressure
decreased bowel sounds may indicate
2
peritonitis or paralytic ileus
normal amount of bowel sounds per minute
5-30
friction rub, high pitched bowel sounds associated with inspiration, may indicate
inflammation of peritoneal surface
tumor, infection, infarct
bruits in aorta, renal, iliac, femoral artery may indicate
abdominal aneurysm
absence of bowel sounds is established after […] minutes of continous listening
5
tympany throughout the abdominal area may indicate
obstruction/distension in ileus
dullness to percussion of the liver may indicate
ascites, hepatomegaly
outpouchings that grow in the colon as we age
diverticula
- LLQ abdominal pain
- middle age man
- pain constant over a few days
- change in bowel habits
- may be able to palpate fullness
classical presentation of…
acute diverticulitis
nutrition management of diverticulitis
high fiber, low fat diet
painless, hematochezia suggests
bleeding diverticulosis
