自发性细菌性腹膜炎(SBP)已被公认为肝硬化腹水患者的并发症,但对其诊断标准仍有争论。通常认为,SBP的预后与诊断及抗生素治疗是否及时有关,SBP腹水培养并非每例都有细菌生长,且细菌培养至少需要24～48小时。Bar-Meir(1979)研究347例肝硬化腹水患者的腹水,发现腹水比重、蛋白和糖的测定对腹水鉴别诊断均无帮助。迄今,早期提示SBP主要 Spontaneous bacterial peritonitis (SBP) has been recognized as a complication of patients with cirrhosis and ascites, but its diagnostic criteria are still debated. It is generally believed that the prognosis of SBP and diagnosis and timely treatment of antibiotics, SBP ascites culture does not have bacterial growth in every case, and bacterial culture at least 24 to 48 hours. Bar-Meir (1979) studied ascites in 347 patients with cirrhotic ascites and found that aspartate specific gravity, protein and sugar were not helpful in the differential diagnosis of ascites. To date, SBP has been primarily suggested
