[Bacterial peritonitis].

In bacterial peritonitis the cause, the time of occurrence--independent of surgery or postoperative-and the duration are relevant factors for therapeutic results. The multiplicity of possible combinations makes judgement difficult about different therapeutic concepts. Accepted general principles are: Antibiotics against aerobics and anaerobics. Pre- and postoperative intensive care (fluid replacement!). Treatment of source by the most secure method. Management of peritonitis by intraoperative cleansing and postoperative lavage, scheduled reoperations or open package.
