What bacteria causes intra-abdominal infections?
Nearly all intra-abdominal infections are caused by multiple microorganisms that constitute the intestinal flora (aerobes and facultative and obligate anaerobes, with Enterobacteriaceae, enterococci and Bacteroides fragilis isolated most frequently).
What is an intra-abdominal infection?
Definitions. Intra-abdominal infection (IAI) describes a diverse set of diseases. It is broadly defined as peritoneal inflammation in response to microorganisms, resulting in purulence in the peritoneal cavity[1]. IAI are classified as uncomplicated or complicated based on the extent of infection[2].
How is intra-abdominal infection diagnosed?
How is an intra-abdominal abscess diagnosed?
- Blood tests. Blood may be drawn to look for signs of infection or an intra-abdominal abscess.
- Imaging tests. The best imaging test to check for an abscess is typically a computerized tomography or CT scan to see inside the belly.
- Physical exam.
What is intra-abdominal pathology?
Introduction. Intra-abdominal infections (IAI) include many pathological conditions, ranging from uncomplicated appendicitis to faecal peritonitis. IAI are classified into uncomplicated and complicated [1]. In uncomplicated IAIs the infectious process only involves a single organ and does not proceed to peritoneum.
What is meant by intra-abdominal?
Medical Definition of intra-abdominal : situated within, occurring within, or administered by entering the abdomen intra-abdominal pressure an intra-abdominal injection.
What causes intra-abdominal abscess?
Intra-abdominal abscesses (abscesses within the abdomen) can develop when the abdominal cavity or an organ in the abdomen is compromised in some way and bacteria are able to enter. Such conditions include appendicitis, bowel rupture, penetrating trauma, surgery, and Crohn’s disease or ulcerative colitis.
What does Extraperitoneal mean?
Medical Definition of extraperitoneal : located or taking place outside the peritoneal cavity extraperitoneal drainage extraperitoneal injury.
What is intra-abdominal process?
Intra-abdominal infection encompasses a diverse spectrum of processes (sterile inflammation, obstruction, perforation, necrosis, primary contamination from trauma or surgery, failed immune system or recent antimicrobial therapy) at a broad range of sites (peritoneal space, retroperitoneum, any abdominal viscous).
What is intra abdominal pathology?
Are intra-abdominal infections associated with a high risk of infection?
In these patients intra-abdominal infections may be associated with a high risk of isolation of resistant pathogens from the intra-abdominal source. Effective management of high risk patients requires the early use of appropriate, broad-spectrum empirical antimicrobial therapy.
What is the pathogenesis of intraabdominal infections?
The pathogenesis of intraabdominal infections is determined by bacterial factors which influence the transition from contamination to infection. Intraabdominal adjuvants and the local host response are additionally important.
Are there evidence-based recommendations for treatment of complicated intra-abdominal infections?
Complicated intra-abdominal infections are an important cause of morbidity and are frequently associated with poor prognosis, particularly in higher risk patients. Well defined evidence-based recommendations for intra-abdominal infections treatment are partially lacking because of the limited number of randomized-controlled trials.
What determines the outcome of intra-abdominal infections in the ICU?
This multinational, heterogeneous cohort of ICU patients with intra-abdominal infection revealed that setting of infection acquisition, anatomical disruption, and severity of disease expression are disease-specific phenotypic characteristics associated with outcome, irrespective of the type of infec …
