 Acute Abdominal Infections

 Abdominal infections can be minor or lifethreatening.

70% of diagnoses can be made based on

history alone.

90% of diagnoses can be made based on

history and physical exam. Expensive tests often confirm what is

found during the history and physical.

 Acute Abdominal Infections

 Acute Abdominal pain is the main,

presenting symptom of patients with Acute Abdominal Infections

 Abdominal pain can represent processes as varied as benign, self-limited viral gastroenteritisto a perforated hollow viscus that can be fatal without intervention

Epigastric pain and indigestion is consideredheart ischemia until proven otherwise in malesover 35 years, females over 45 years, and forpatients with a cardiac history.

Large majorities of females with lower

abdominal pain have gynecological problems.

Pain Associated with Acute Abdominal Infections 

Dull Pain Dull pain is commonly associated with

inflammation and low-grade infection.

Intermittent Pain Intermittent pain is commonly associated with gastroenteritis and

small bowel obstruction.

Severe Pain Severe pain controlled by medication iscommonly associated with pancreatitis,

peritonitis, small bowel obstruction,renal colic, and biliary colic. Severepain not controlled by medications iscommonly associated with infarction

or rupture.

Essential History

 A carefully taken history describing the pain

is the most powerful diagnostic tool. The following features must be determined:

Onset: How did pain start? -

 Acuteness:  Sudden (minutes) - ruptured viscous,

aneurysm or ectopic pregnancy 

over 1-2 hours - pancreatitis, bowelobstruction, renal colic

over several hours - cholecystitis,

appendicitis, PID

Consider Rectal Exam on Males & Vaginal/Rectal on

FemalesRectal Examination

Rectal mass - may cause large bowel obstruction  Abdominal pain on palpating pelvic peritoneum- pelvic

peritonitis

Blood - IBD, ischemic bowel, hemorrhoids

Impacted stool- constipation

 Vaginal Examination

Cervical pain - Pelvic inflammatory disease (PID), ectopic

pregnancy  Purulent discharge - PID

Bulky uterus - pregnancy 

 Adnexal mass - ectopic pregnancy, ovarian cyst, tumor.

Clinical Decision Making: Anticipated Medical Care

of Acute Abdominal Infection

Lab Tests CBC with differential, electrolytes, BUN,

creatinine, glucose, LFTs, amylase,lipase, PT, PTT (WBC >20,000 suggestssepsis and may require surgery)

Radiology Tests  Abdominal ultrasound, spiral CT (nooral contrast needed), abdominal CT(oral contrast needed), x-rays of thechest and abdomen, intravenous

pyelogramOther tests Pelvic/Rectal exam, orthostatic vital

signs, Stool Guiac/culture, Urinalysis

Diet NPO

Clinical Decision Making: Anticipated Medical Care

of Acute Abdominal Infection

Medications Anti-inflammatory, antipyretic, antiemetic,

 Analgesic, Antibiotics

Implicationsfor Practice:

Disposition

 The FNP must determine what is the mostappropriate setting for care. Whether to

initiate treatment as an outpatient setting, referpatient to the hospital or to call 911,depending on patient’s health status

 Worse case

scenario

 An unsuspected abdominal aortic aneurysm

rupture resulting in sudden circulatory collapse from loss of volume. An older adultmale with a history of DM, HTN, andsmoking is the most common patient type foran aneurysm.

 Acute Appendicitis Appendicitis is an

inflammation of the vermiform appendix.

 All people aresusceptible, the most

common occurrencesis between ages 20 and30 years, although itmay develop at any age.

It is very rare beforethe second year and

after the fiftieth year

 Acute Appendicitis: Etiology &

Pathophysiology  Obstruction of the lumen with stool, tumors or

foreign bodies with consequent bacterialinfection is the most common theory.

 The obstructed lumen does not allow drainage of 

the appendix and as mucosal secretion continues,intraluminal pressure increases.

 The resultant increased pressure decreases

mucosal blood flow and the appendix becomeshypoxic.

 The mucosa ulcerates promoting bacterialinvasion with further inflammation and edema

 Acute Appendicitis: Physical Findings

 A dull right lower quadrant pain with rebound at

McBurney’s Point (just inside the iliac crest) Rovsing’s Sign: is an increase in right lower

quadrant pain initiated by palpation of the left lower

quadrant. It is suggestive of acute appendicitis. Obturator Sign: flexion and lateral rotation of the

thigh causes hypogastric pain, a sign of pelvic

abscess and appendicitis. Psoas Sign (iliopsoas test): extension and elevation

of the right leg cause pain, a sign of appendicitis.

 Acute Cholecystitis Is an acute inflammation

of a distendedgallbladder usually caused by an impactedstone in the cystic duct.

Stones may consist of cholesterol or pigmentssuch as Ca+ birubinate.

In the USA, over 80% of the stones arecholesterol.

 Acute Diverticulitis: Etiology &

Pathophysiology

It commonly occurs in the sigmoid colon. Cause of diverticulitis has been attributed

to a low-fiber diet and intraluminal

pressure. The resulting increased intraluminal

pressure causes the diverticulum to

perforate.

Bacterial spillage may occur with abscess

formation or frank fecal peritonitis.

 Acute hepatitis is an

infection of the livercaused by a Hepato-tropic virus (A, B, C, D,

E) and other viruses >250,000 new 

infections occurannually in the USA.

 Acute Hepatitis isencountered often inthe office and clinic.

 Acute Hepatitis: Etiology & Pathophysiology

Hepatitis A – Fecal to oral transmission

Hepatitis B – Percutaneous (needle stick), sexual,perinatal transmission

Hepatitis C – Percutaneous transmission (IV drug 

use accounts for over 50% of the reported cases.) Hepatitis D – IV transmission (IV drug users and

transfusions) Endemic among HBV (hepatitis B

 virus) carriers in the Mediterranean bases and areasof South America

 Acute Pancreatitis

Is an inflamed condition of 

the pancreas that can beacute or chronic.

 The most common cause of pancreatitis is alcohol intake.

 The 2nd most commoncause is cholelithiasis.

 A perforated duodenal ulcer

that erodes through thepancreatic wall and into thepancreas can progress topancreatitis.

 Acute Pancreatitis: Clinical Decision Making

 The amylase and lipase are elevated.

In acute pancreatitis, amylase is often elevatedmore than three times normal within a few hours of onset and remains elevated for threedays.

 Amylase > 1,000 IU in absence of GIperforation makes diagnosis very likely 

 After twenty-four hours, serum lipase levels rise

and remain elevated for ten days. Ultrasound often does not visualize the pancreas

because of overlying gas but may detect

gallstones.

Hospital Referral

Management may include analgesics and IV fluids, Antibiotics if infection established, NPO.

Surgery indicated for pancreatic abscess orpseudocyst.

 Acute Respiratory Distress Syndrome may resultfrom acute pancreatitis or by associated sepsis andhypovolemia.

Pancreatic exudates are thought to destroy thesurfactant.

Hypokalemia and Hyperglycemia are common

complications of pancreatitis.

Pancreatitis Education

Home instructions include a low-fat, no-alcohol, and no-caffeine diet.

Limiting fat intake and avoiding alcoholhelps prevent stimulation of the pancreas.

No caffeine prevents stimulation of gastric

acid that activates the pancreas. 90% of the cases subside after three to

seven days.

10% of U.S. population suffers from peptic ulcerdisease. $6 billion in the USA each year in direct

costs of treatment of peptic ulcer disease Peptic ulcers can develop in the lower esophagus,

stomach, pylorus, duodenum or jejunum

80% of peptic ulcers are duodenal ulcers Most common in men between ages 20 to 50.

Gastric Ulcers affect the stomach mucosa are most

common in people ages 55 to 70 (chronic users of NSAIDs or ETOH)

5% to 10% of patients develop complications thatnecessitate surgery.

Infection with Helicobacter Pylori (gram-negative spiral microaerophilic bacterium)

NSAIDs

Pathologic hypersecretory states such asZollinger-Ellison Syndrome

 An imbalance exists between aggressive factors

such as gastric acid and defensive factors thatenhance mucosal integrity such as mucus,prostaglandins, growth factors, blood flow,

bicarbonate, and cell turnover

In a Research Study, scientists found that humanintestinal cells with excess iron were more susceptible

to attack by bacteria that cause infection of the smallintestine.

Researchers exposed cells to a common form of iron

that is present in iron supplements. Iron-laden cells were then exposed to Salmonella

enteritidis.

Findings were that cells containing high levels of iron were more easily invaded by the bacteria

Greater numbers of bacteria survived inside cells with

high iron than cells with normal amounts of iron.

y Cells with elevated levels of iron also synthesized

higher amounts of cytokines and chemokines -classes of defense proteins -- in response tobacterial infection.

 The secretion of many of these proteins is

associated with the development of inflammation.

 The finding suggests that excess iron in theabsorptive cells in the gut may increase both therisk of infection and damage other tissues in theintestine in response to the greater degree of inflammation.

 To prevent iron overload, the researchers suggesta revision of the standard policy of iron

fortification of the general population. They recommend periodic evaluation of the iron

status of individuals, particularly women in thereproductive period of their life cycle.

Researchers are planning further experiments toexplain why intestinal cells with high iron levelsare more readily infected.

 The study suggests that enriching breakfastcereals and other foods with high doses of iron -a nutritional strategy, could be causing otherhealth problems.

 A Research Study was conducted to determine whether serious adverse effect profiles differ forsulphasalazine and mesalazine.

Sulphasalazine and mesalazine are 5- Aminosalicylates that are extensively prescribed

for the treatment of ulcerative colitis but have a wide range of described adverse effects

 Adverse effect profiles were categorized for

interstitial nephritis, pancreatitis, serious skinreactions, hepatitis and hepatic failure, andblood dyscrasias.

Research: Sulphasalazine & Mesalazine

Report rates were calculated using prescribing 

data from the Department of Health andcompared for mesalazine and sulphasalazine.

Further analysis was undertaken for

sulphasalazine according to disease indication of inflammatory bowel disease or rheumatoidarthritis.

Methods: Analysis of suspected serious adversereactions reported to the Committee on Safety of Medicines of the UK in 1991 – 1998.

Research Results: Sulphasalazine & Mesalazine

 A total of 4.7 million prescriptions were dispensedfor sulphasalazine compared with 2.8 million formesalazine.

Interstitial nephritis was only described formesalazine, with 11.1 reports per million

prescriptions.

Pancreatitis was reported 7 times as frequently formesalazine (7.5 per million prescriptions) compared

 with sulphasalazine (1.1 per million prescriptions)

 There were no reports of serious skin disorders inpatients prescribed sulphasalazine for IBD.

Blood dyscrasias were reported significantly moreoften in patients receiving sulphasalazine for

rheumatoid arthritis than for IBD and there was asimilar trend for hepatic disorders.

Conclusions: Spontaneous reports suggest that

 within the five sets of disorders considered, there isno evidence to indicate a safety advantage of mesalazine over sulphasalazine in the treatment of inflammatory bowel disease.

Pancreatitis and interstitial nephritis appearsignificantly more common with mesalazine, andadvice on renal monitoring in patients who receive

mesalazine may need reinforcing.
