Lecture 18.2: Intraabdominal Infections Flashcards
What is Intra-abdominal infections?
- Infections within the peritoneal cavity or retroperitoneal space
Peritoneal: stomach, small/large bowel, lover, gall bladder spleen
Retroperitonal: Kidneys, pancreas, adrenal glands, aorta, vena cava.
What are the four types of Intra-abdominal Infections?
- Uncomplicated
- Complicated
- Community- acquired
- Healthcare-acquired
What is Uncomplicated Intra-abdominal Infections?
- IN vicersal structures [liver, gall bladder, spleen, pancreas, kindey…] and NOT into peritoneum
What is Complicated in Intra-abdominal Infections?
- INTO the peritoneal space possibly making abscess
What is Community-Acquired Intra-abdominal Infections?
- < 48 hours within a Hospital
Like CAP
What is Healthcare-Aquired Intra-abdominal Infections?
- > 48 hours in a hospital
Like HAP/VAP
What are the 2 general types of Intra-abdominal Infections>
- Peritonitis: Inflammation of Peritoneal lining [Primary, Secondary, Tertiary]
- Abscess: Purulent collection of fluid [immune system trys to put it in one spot]
What is Secondary Peritonitis in Intra-abdominal Infections?
- Bacteria in Peritoneum affecting GI tract; by diseases, injuires, trauma, obstruction…
What are some of the most common caustive pathogens in Secondary Peritonitis?
- Gram (-): E. Coli
- Gram (+): Strep
- Anaero: B. Fragilis
What is the pathogensis or pathphysiology of Secondary Peritonitis in Intra-abdominal Infections?
What are the 5?
- Inoculum overpowered Host; Foreign Body, Large Bacterial Inoculum, Constant Contamination, Contamination with mix organisms, Impaired Defenses
What is the systemic responses that may happen during Secondary Peritonitis in Intra-abdominal Infections?
- GI: Increased fluid = distention
- Cardio: Fluid shifts = decreased cardiac output, hypotension, venous return
- Respiratory: Fast Shallow breathes
- Renal: Failure
- Metabolic: wieght loss
What are the symptoms of Secondary Peritonitis in Intra-abdominal Infections?
- Abdominal Pain
- Anrexia
- N/V
- Fever +/- Chills
- Thristy
What are some of the Physical Finding for Secondary Peritonitis in Intra-abdominal Infections?
- Lie VERY still in bed
- Rapid Breathes
- Fever
- Voluntary Guarding
What are some of the test results for Secondary Peritonitis in Intra-abdominal Infections?
- Leukocytosis with LEFT SHIFT
- High BUN
- X-Ray or CT scan
- Blood Cultures
What is important to know about Surgery in the treatmet of Secondary Peritonitis in Intra-abdominal Infections?
- Source Control: repairing skin damage; removing fluids = decreases infection risks
- COLLECT this fore susceptibilty testing
