Spontaneous bacterial peritonitis (SBP) is a peculiar form of peritonitis occurring in the absence of an obvious source of contamination. It occurs in people with ascites , including children. Intra-peritoneal dialysis predisposes to peritoneal infection (sometimes named "primary peritonitis" in this context).
Clinically, the most useful measure is the difference between ascitic and serum albumin concentrations. A difference of less than 1 g/dl (10 g/L) implies an exudate. [9] Portal hypertension plays an important role in the production of ascites by raising capillary hydrostatic pressure within the splanchnic bed.
The serum-ascites albumin gradient (SAAG) is the most useful index for evaluating peritoneal fluid and can help distinguish ascites caused by portal hypertension (cirrhosis, portal vein thrombosis, Budd-Chiari syndrome, etc.) from other causes of ascites. SAAG is calculated by subtracting the albumin measure of ascitic fluid from the serum value.
Spontaneous bacterial peritonitis (SBP) is the development of a bacterial infection in the peritoneum, despite the absence of an obvious source for the infection. [1] It is specifically an infection of the ascitic fluid – an increased volume of peritoneal fluid. [2] Ascites is most commonly a complication of cirrhosis of the liver. [1]
The most common infection is peritonitis, followed by lung, skin, and urinary infections, meningoencephalitis and in the most serious cases septicaemia. The most notable of the causative organisms are Streptococcus pneumoniae and Haemophilus influenzae. Spontaneous bacterial peritonitis can develop where there is ascites present. This is a ...
The test was originally developed by the Italian researcher Rivalta around 1900 and was used to differentiate transudates and exudates in human patients. It is also useful in cats to differentiate between effusions due to feline infectious peritonitis (FIP) and effusions caused by other diseases. [2]
Between the visceral and parietal peritoneum is the peritoneal cavity, which is a potential space. [1] It contains a serous fluid called peritoneal fluid that allows motion. This motion is apparent of the gastrointestinal tract. The peritoneum, by virtue of its connection to the two (parietal and visceral) portions, gives support to the ...
A milky appearance of the fluid can indicate lymphoma or malignant peritoneal ascites. Cloudy or turbid fluid can indicate possible infection or inflammation within the peritoneal cavity. Straw or light yellow colored fluid indicates more plasma-like and benign causes of peritoneal ascites. [3] Ascitic fluid, 7 litres, drained during paracentesis
