Term
Primary peritonitis from peritoneal dialysis. what abx do you use?
Definition
Treatment: 14 DAYS (or longer if there is fungal infxn)

-Vancomycin OR Cefazolin] + [3rd gen Ceph OR Aminoglycoside]

-But she would never use cefazolin with 3rd gen ceph

-Try cefazolin with AG, or vanc and gent/AG, or vanc and 3rd gen ceph.

Don’t have to worry about systemic resistance because it doesn’t get into the blood, and can use smaller amounts bc goes right to site of infx, inflamm will help
Term
Primary peritonitis from cirrhosis with cites. what abx do you use?
Definition
Treatment: 5 DAYS + prophylaxis indefinitely(?)

Primary: [Cefotaxime]

Alternatives:
 Add Clinda or metronidazole if anaerobes are suspected OR
 Other 3rd gen ceph, Extended spectrum pcn(resistant to amp so don’t use), Aztreonam, or Imipenem
 Aminoglycoside with antipseudomonal pcn
Term
Primary peritonitis from peritoneal dialysis. What bacteria commonly cause this?
Definition
Gram Positive skin infections
o S. Epidermidis, S. Aureus, Streptococci, Diptheroids
Term
Primary peritonitis from cirrhosis with cites. What bacteria commonly cause this?
Definition
Gram negative
o E. coli (most common)
o Haemphilus pneumoniae
o Klebsiella
o Anaerobes
o S. Pneumonia, Pseudomonas
Term
What bacteria commonly cause Secondary Peritonitis?
Definition
Usually polymicrobial
 E. Coli, Bacterioides Fragilis, Enterococcus, Streptococci

Female genital tract: aerobic and anaerobic. Get to peritoneum through fallopian tubes.
 Lactobacilli, eubacteria, clostridia, anaerobic strep, aerobic strep, staph epidermidis
Term
Secondary Peritonitis: Community Acquired. How do you treat this ir Mild-Moderate and also if Severe??
Definition
Antibiotics: 4-7 DAYS (unless difficult source control, still sick, feverish, etc)

Mild to Moderate (monotherapy-do not need to cover enterococcus faecalis!!!)
o Ticarcillin-Clavulanate
o Cefoxitin
o Ertapenem
o Moxifloxacin (not as good tho)
o Tigecycline
o Metronidazole + anyone of these to cover gram neg: Cefazolin, Cefuroxime, 3rd gen Ceph, Levo or Cipro



High Severity or risk (Combo therapy-must cover enterococcus faecalis!!!!)
o Imipenem-cilastatin, meropeneme, doripenem
o Piperacillin-tazobactam
o Metronidazole + Cefepime or Ceftazidime or Cipro or Levo
Term
Secondary Peritonitis: Hospital Acquired. How do you treat this?
Definition
Treat as it was high severity community acquired
 Add antifungal ONLY if Candida grows (it’s normal to have some in GIT)
 MRSA coverage (if exposure to antibiotics previously or have MRSA) – Vancomycin


High Severity or risk (Combo therapy-must cover enterococcus faecalis!!!!)
o Imipenem-cilastatin, meropeneme, doripenem
o Piperacillin-tazobactam
o Metronidazole + Cefepime or Ceftazidime or Cipro or Levo
Term
Describe Tertiary Peritonitis.
Definition
-Infection that persists or recurs at least 48 hours after apparently adequate management of primary or secondary peritonitis.

-More chronic and complicated
Term
What are the predictors of antibiotic failure?
Definition
Delay in intervention

High severity (APACHE ≥15)

old age

comorbidity

degree of organ dysfunction

Low albumin level

Poor nutritional status

Degree of peritoneal involvement or diffuse peritonitis

Inability to achieve adequate debridement or control of drainage,

malignancy

transplant (may be immunosuppressed),

hospital stay prior to operation ≥5 days
Term
The following are indicative of _________ Peritonitis.


Presentation:
Indolent, N/V, abd tender, low fever, hypoactive bowel sounds, worsening encephalopathy in liver disease cloudy diasylate, fluid culture +, Bacterial on gram stain, inc WBC, Ascitic fluid >300 leukocytes/mm3, etc
Definition
Primary!
Term
The following are indicative of ______ Peritonitis:


Presentation:
 Often acute (SUDDENLY HURTS, like appendicitis), Generalized abdominal pain
 Tachypnea, Tachycardia
 N/V, Fever
 Hypotension & Shock
 Dec urine output, Hypovolemia
 Absent bowel sound, Board-like abdomen
 Leukocytosis
Definition
Secondary
Term
The following are indicative of ______:

: Indolent, Fever often low grade, Leukocytosis, ileus, Abd pain, Abd distension
Definition
Abcess.


-Falls within category of secondary or tertiary peritonitis

-May occur without preceding generalized peritonitis

-Causes overlap with peritonitis: Appendicitis, Pancreatitis, Pelvic Inflammatory Disease.
Term
what drugs do you use for primary and secondary propylaxis?
Definition
ciprofloxacin, norfloxacin, and bactrim!

prophylaxis is specifically for liver dz pts
