Abdominal Pain
Abdominal pain is common and often inconsequential.
When is abdominal pain concerning?
- May be sole indicator of the need for (1) and must be attended to quickly
- Particular concern in patients who are very ___ or very _____ and those who have ____ infection or taking Rx (1)
Abdominal pain is common and often inconsequential.
ACUTE AND SEVERE almost always a symptom of intra-abdominal disease sign of pathology)
- May be sole indicator of the need for surgery and must be attended to quickly.
- Particular concern in patients who are very old or very young and those who have HIV infection or taking immunosuppressants.
The Peritoneum
A thin serous membrane
Parietal Peritoneum =
Visceral Peritoneum =
Peritoneal cavity =
Lines the walls of the abdominal and pelvic cavities
Lines the organs
Space between the two layers
It is the most common form of abdominal pain and can be described as vague, dull and nauseating. It is poorly localized.
- Responds mainly to (2) motions, not to cutting or tearing
Visceral Pain
- Responds mainly to distension and muscular contraction
Origins of Abdominal Pain
- (1) structures (stomach, duodenum, liver, and pancreas) cause pain where?
- (1) structures (small bowel, proximal colon, and appendix) cause pain where?
- (1) structures (distal colon and GU tract) cause pain where?
- (1): indigestion, cholecystitis
- (1): intestinal obstruction, early appendicitis
- (1): small or large intestine, urinary tract infection, inflammatory bowel disease
- Foregut structures (stomach, duodenum, liver, and pancreas) cause upper abdominal pain.
- Midgut structures (small bowel, proximal colon, and appendix) cause periumbilical pain.
- Hindgut structures (distal colon and GU tract) cause lower abdominal pain.
- Epigastric: indigestion, cholecystitis
- Periumbilical: intestinal obstruction, early appendicitis
- Suprapubic: small or large intestine, urinary tract infection, inflammatory bowel disease
Type of abdominal pain perceived distant from its source. This is due to the lack of a dedicated sensory pathways in the brain for information concerning internal organs.
Examples (3)
Referred Pain
- Scapular pain dt biliary colic (right shoulder blade pain from gallbladder inflammation irritating phrenic nerve)
- Groin pain dt renal colic
- Shoulder pain from diaphragm irritation (can be rt biliary colic)
Pain coming from lining of the abdominal wall and pelvic cavities, characterized as _____, ____ localized
- It is often mediated by (3) I’s.
- This may include acute (2) rather than biliary colic which started as visceral pain.
Parietal or Somatic Pain
sharp, well localized
- It is often mediated by acute inflammation, ischemia or infectious processes.
- This may include acute appendicitis or acute cholecystitis rather than biliary colic which started as visceral pain.
CHRONIC abdominal pain associated with history of multiple body complaints, chronic non-progressive course, somatic symptoms of depression. (ie. IBD)
Examination maneuver =
Psychogenic pain
Examine using deep palpation while pt is distracting using stethoscope for “auscultating”

GERD Pharm Tx
(2) (1),(3) drug classes
H2 Receptor Antagonist
Pepcid
Proton Pump Inhibitor
(Omeprazole (prilosec), Lansoprazole (prevacid), Esomeprazole (nexium))
H2 Receptor Antagonist
(Pepcid)
MOA
Dosing frequency
Suppress acid by reversibly binding to histamine receptors located on gastric parietal cells (blocking endogenous histamine)
QD or BID
Proton Pump Inhibitor
(-prazoles)
MOA
Dosing frequency
Indication
blocks proton pump from secreting acid so
should be taken 30-60 min before you eat (usually when wakin gup in morning), QD
Reserved for failure of H2 blocker or erosive esophagitis
PPI LT concerns
(5)
- PPI associated PNA pneumonia (aerobic bacteria grow in the stomach with increasing pH and micro-aspiration and lung colonization may occur)
- C.diff (stomach acid suppresses C.diff)
- Hypomagnesemia
- Decrease in Calcium absorption
- Interference with Vit B12 absorption
Avoid cimetidine: a lot of cytochrome P450 interactions
Tx for GERD follow up
- Re-evaluate pt after 2 weeks, if controlled, complete therapy for _-_ weeks
- After 8-12 weeks =
- If pts GERD is recurrent in nature =
- If symptoms unresolved in 8-12 weeks of therapy =
- Re-evaluate pt after 2 weeks, if controlled, complete therapy for 8-12 weeks (2-3m treatment period then try to get them off)
- After 8-12 weeks, discontinue or lower med to lowest possible dose that provides relief
- Some pts require low-dose maintenance therapy indefinitely: recurrent nature
- If symptoms unresolved in 8-12 weeks of therapy, refer to a gastroenterologist (to r/o ulcer, barrett’s)
Which of the following is not an “alarm” finding in the person with GERD symptoms?
- Weight gain
- Dysphagia
- Odynophagia (painful swallowing)
- Iron deficiency anemia
- Weight gain
- Dysphagia
- Odynophagia (painful swallowing)
- Iron deficiency anemia
A client with gastro-esophageal reflux disease (GERD) is prescribed famotidine (Pepcid). In order to provide effective teaching, the NP must include which information about the action of the drug?
- It improves motility
- It coats the distal potion of the esophagus
- It increases the gastric pH
- It decreases the secretion of gastric acid
- It improves motility
- It coats the distal potion of the esophagus
- It increases the gastric pH
- It decreases the secretion of gastric acid
Answer is 4) Famotidine is a histamine-2 receptor antagonist and reduces the secretion of gastric acid (option 4). This class of drugs does not have a direct effect on reflux or GI motility. Metoclopramide or Reglan improves GI motility (option 1). Sucralfate or Carafate coasts the ulcer (option 2). Antacids neutralize the hydrochloric acid in the stomach (option 3).

- Will need frequent (1) depending on molecular changes of their cells
- Presentation is usually heartburn or dysphagia
- This is a strong correlation with LT acid exposure and risk of adenocarcinoma
- Dose-related:refers to risk of development of adenocarinoma with Barrett’s esophagus is <1% annually, 5 and 10-fold in persons with low grade and high grade dysplasia
