    Spontaneous Bacterial Peritonitis I find that many students get this confused and they are exactly sure when to choose this as being the diagnosis. Let's take a look at first the risk factor for SBP. Recent gastrointestinal hemorrhage. Ascitic fluid less than 1 gram. In other words, there is Ascitis taking place. Therefore, Remember, the peritoneal cavity has not been compromised. There is every possibility that the fluid within the peritoneal cavity may then become infected. We call this Spontaneous Bacterial Peritonitis. The name pretty much tells you exactly what's going on with this risk factors. And there might be prior episodes of SBP - Spontaneous Bacterial Peritonitis. Microbiologically, the gram negative organisms will play a role 70% of the time if not greater. That is extremely concerning. You might have Streptococci the gram positive organisms. often times though however, you might find, polymicrobial infection therefore suggesting that the origin of the Spontaneous Bacterial Peritonitis might have been the bowel that then perforated. How? What if it was diverticular disease? which is extremely common in the U.S. Where diverticulosis, diverticulitis and with enough inflammation, a rapture, there's every possibility that it might result in Spontaneous Bacterial Peritonitis. Clinical presentation: Severe abdominal pain, fever, and perhaps encephalopathy if the issue took place and originated from the liver. Diagnosis: With ascitic fluid, in which you expect "Aperitonitis" you can expect your neutrophils to be quite high bedside inoculation of ascetic fluid into blood culture bottles increases your yield. There, that way, immediately you can tell as to whether not your patient is suffering from SBP. Something that you very much want to keep in mind, when the patient is suffering from ascites. Management, third generation cephalosporin. Albumin because the liver might be depressed. And phrophylaxis with Co-trimoxazole, sulfamethoxazole and Trimethoprim. ...
