Term

Acute Abdomen

Definition

  • Sudden onset of abdominal pain
  • Generally associated with:
    • Severe progressive problems that require medical attention
    • Peritonitis will usually develop if the acute abdomen is not treated - can be fatal

Term

Physiology of the Abdomen

Definition

  • Solid and hollow (GI, Genital, Urinary) organs
  • Parietal Peritoneum - lines abdominal cavity
  • Visceral Peritoneum - lines the organs
  • Small amount of Peritoneal fluid to bathe/lubricate organs
  • Peritonitis- Foreign material can cause irritation
  • Retroperitoneal - behind the peritoneal:
  • Kidneys, Ovaries, Pancreas

Term

Physiology of the Abdomen

2 Different types of nerves:

Parietal Peritoneum

Definition

  • Parietal peritoneum - supplied by spinal cord nerves that supply skin of abdomen
  • Perceives same types of sensations (pain, touch, pressure, heat, and cold)
  • Can easily:
    • identify
    • Localize a point of irritation

 

Term

 

Physiology of the Abdomen

2 Different types of nerves:

Visceral Peritoneum

 

Definition

  • Supplied by the autonomic nervous system
  • Less able to localize sensation (patient can't localize or describe pain)
  • Stimulated when distention or contraction of the hollow abdominal organs activates the stretch receptors
  • Often interpreted as colic - severe intermittent cramping pain
  • Referred Pain - Perceived art a distant point on the surface of the body (shoulder, back, or deep)

 

Term

 

Physiology of the Abdomen

2 Different types of nerves:

Visceral Peritoneum

 

 

Definition

 

  • Referred pain is result of - connections between the body's 2 separate nervous systems
  • Somatic Nervous System - spinal cord supplies sensory nerves to the skin and muscles
  • Autonomic Nervous System 
    • Controls abdominal organs and blood vessels

 

Term

Physiology of the Abdomen

2 Different types of nerves:

Visceral Peritoneum


Definition

  • The nerves connecting these 2 systems cause the stimulation of the autonomic nerves to be perceived as stimulation of the spinal sensory nerves
  • Eg. Acute cholecytticis - inflammation of the gall bladder may cause pain in the right shoulder because the autonomic nerves serving the gall bladder lie near the spinal cord at the same autonomic level as the spinal sensory nerves that supply the skin of the shoulder

Term

Causes of Abdominal Pain

Solid Organs

Definition

 

  • Liver
  • Spleen
  • Pancreas
  • Kidneys
  • Ovaries
  • Adrenal Glands

 

Term

Causes of Abdominal Pain

Hollow Organs

 

Definition

 

  • Gall Bladder
  • Stomach
  • Small Intestine
  • Large Intestine
  • Bladder
  • Bile Duct
  • Appendix
  • Rectum
  • Fallopian Tubes
  • Uterous

 

Term

Causes of Abdominal Pain

Definition

  • Visceral Peritoneum usually irritated 1st:
    • Early abdominal pain tends to be vague and poorly localized
  • Perietal Peritomeum becomes irritated:
    • Pain becomes more severe and more specifically located

Term

Causes of Abdominal Pain

Digestive System

Definition

  • Ulcers (erosions of the stomach or the duodenum) - most common due to overactivity of digestive juices
  • Perforation of at ulcer causes severe peritonitis and acute abdomen
  • Gall Bladder - storage pouch for digestive juices and waste from the liver
  • Gall Stones - can form and block the outlet from the Gall Bladder = pain
  • Cholecystitis = severe inflammation of the Gall Bladder (blockage doesn't pass)

 

Term

Causes of Abdominal Pain

Digestive System

Definition

  • Pancreas - Retroperitoneal - pain referred to the back
  • Forms digestive juices
  • Produces Insulin
  • Pancreatitis - inflammation of the pancreas
  • Caused by:
    • Blocking Gall Stone 
    • Alcohol Abuse
    • Other Diseases

 

Term

Causes of Abdominal Pain

Digestive System

Definition

  • Appendix - a small recess in the large intestine
  • Inflammation or Infection frequent cause of Acute Abdomen

Term

Causes of Abdominal Pain

Digestive System

Definition

Diverticulitis - Inflammation of small pouches in the Large Intestine

Pouches can become blocked and infected leading to:

Pain

Perforation

Severe Peritonitis

Term

Causes of Abdominal Pain

Urinary System

Definition

  • Kidneys - stones form from materials normally passed in urine
  • If a stone passes - sever pain = Renal Cholic
  • Frequently associated with blood in the urine
  • Kidney Infections - severe pain - often in the flank
  • Often quite ill with a high fever

 

Term

 

Causes of Abdominal Pain

Urinary System

 

Definition

  • Cystitis - Bladder Infection - more common in women
  • Lower abdominal pain

 

Term

 

Causes of Abdominal Pain

Uterus and Ovaries 

 

Definition

  • Always consider that a women with lower abdominal pain and tenderness may have a problem related to the ovaries, Fallopian Tubes, or Uterus
  • Mittelschmerz (associated with the release of an egg from the ovary)- common lower abdominal pain - short lived

Term

 

Causes of Abdominal Pain

Uterus and Ovaries 

Pelvic Inflammatory Disease (PID)

 

Definition

  • Infection of the Fallopian Tubes and surrounding tissues of the Pelvis
  • Causes acute pain and tenderness in the lower abdomen may be intense and cause High fever
  • Promptly transport
  • Ectopic Pregnancy - abrupt abdominal pain & massive internal hemorage
  • Hypovolemic Shock - Immediate Transport

Term

Other Organ Systems

Definition

  • Aorta - lies immediately behind the peritoneum on the spinal column 
  • Older - walls become thin - aneurysm
  • Pulsating mass may be felt in the abdomen
  • Rarely associated with symptoms - occurs slowly
  • If Aneurysm ruptures - massive hemorrhaging & Acute peritoneal irritation
  • Severe Back Pain or pressure of blood on the back
  • Bleeding - profound shock
  • Handle patient gently

Term

Pneumonia

Definition

  • Esp. in the lower parts of the lung may cause:
  • Ileus & Abdominal Pain
  • Problem lies in an adjacent body cavity, but the intense inflammatory response can effect the abdomen

Term

Hernia

Definition

 

  • A protrusion of an organ or tissue through a hole in the body wall, covering its normal site
  • Every organ can herniate in certain circumstances
  • Can occur as a result of:
    • A Congenital Defect (around the umbilicus)
    • A surgical Wound that has failed to heal properly
    • Natural weakness of an area, such as the groin
  • Do not always produce a mass or lump that the patient is aware of

 

Term

Hernia

 

Definition

  • Reducible Hernia - May disappear back where it belongs
  • Incarcerated Hernia - can't be pushed back
  • Strangulation can occur
  • Contents become compresses - compromises the blood supply
  • Serious medical Emergency - Surgery

Term

Hernia

Signs and Symptoms of Serious Hernia Problems

Prompt Transport

Definition

  • A clear statement that a mass was reducible, but no longer is
  • Pain at the hernia site
  • Tenderness when the hernia is palpated
  • Red or Blue skin discoloration over the hernia

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Pain and Tenderness - most common
  • May be sharp or difussed
  • Localized pain - clue to problem organ
  • Peritonitis typically causes ileus (paralysis of the muscular contractions that normally propel material through the intestine)
  • Retained gas and feces cause abdominal Distention

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Nothing can pass so patient throws up (emesis)
  • Almost always associated with:
  • Nausea & vomiting (in that order)
  • Look at patient's abdomen to gauge the degree of distention
  • Distention begins shortly after muscular contractions of the bowel have ceased
  • Pulse and BP may change significantly, or not at all

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Anorexia - loss of hunger or appetite
  • Non- Specific Symptom
  • Almost universal complaint in GI or abdominal issues
  • Peritonitis - loss of body fluid into the body cavity
  • Usually results from abnormal shifts of fluid from the blood stream into body tissues
  • Fluid shift decreases the volume of circulating blood = decreased BP or Shock

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Shock = the inadequate perfusion due to the collapse of the Cardio-Vascular system
  • Patient may have normal vital signs or may present with:
    • Tachycardia
    • Hypotension
  • Fever may or may not be present

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Tenderness of abdominal muscles over the irritated area
  • Muscles may become rigid (involuntary effort to protect the abdomen)
  • Guarding - board-like muscle spasm
  • Can be seen with major problems such as:
    • Perforated Ulcer
    • Pancreatitis

 

Term

Signs & Symptoms of Acute Abdomen

Definition

  • Observe position patient finds most comfortable - provides a clue as the what hurts
  • EG.
  • Appendicitis - pull up right knee
  • Pancreatitis - lie curled up on 1 side

 

Term

Assessment of Acute Abdomen

Definition

General Impression

  • LOC - AVPU
  • Chief Complaint
  • ABCs
  • Circulation - for major bleeding
  • Pulse rate and quality (condition) - may indicate shock - high flow Oxygen, elevating legs 6 - 12"
  • Keep patient warm

Term

 

Assessment of Acute Abdomen

 

Definition
