title: Early diagnosis of peritoneal infection by simultaneous measurement of lactate concentration in peritoneal fluid and blood.
abstract: The level of lactate in peritoneal fluid has been suggested to be of great value in the early diagnosis of peritoneal infection [5]. However, this value is affected by multiple systemic factors producing lactic acidosis; these contributed to the high rate of false positive results, obtained in that study. In our study, a better correlation has been found between the peritoneal fluid to blood lactate gradient levels and the presence or absence of peritoneal infection. A threshold gradient level of 2.2 mmol/l in a total of 37 infected and 48 non-infected samples gave the best prediction with a sensitivity of 95% and a specificity of 96%.
