一、合并细菌感染病毒性肝炎继发胆道细菌感染比较常见。在重症肝炎肝衰竭时更容易发生全身性继发性感染。Gimson等(1982)在103例暴发性肝衰竭患者的回顾性分析中发现,其细菌感染发生率为22%,比接受血液透析疗法的急性肾功能衰竭患者的细菌感染率(11%)高一倍。继发感染发生后,病原微生物的毒素增加,加重肝脏的病变,并对机体产生一系列不良的影响。重症病毒性肝炎继发细菌感染以败血症、呼吸道及腹腔多见,其次为泌尿道、消化道及胆道等。病原菌常见为革兰氏阴性杆菌,产碱杆菌、绿脓杆菌、沙门氏菌,少数为革兰氏阳性球菌。发生革兰氏阴性杆菌败血症者,多找不出原发感染病灶。临床表现为发热,低血压或出现休克、出
First, the merger bacterial infection secondary to viral hepatitis biliary bacterial infection is more common. In severe hepatitis, liver failure is more prone to systemic secondary infection. In a retrospective analysis of 103 patients with fulminant hepatic failure, Gimson et al. (1982) found that the incidence of bacterial infections was 22%, one (11%) higher than that of patients with acute renal failure who received hemodialysis Times Secondary infection occurs, the pathogenic microorganisms increased toxins, increased liver disease, and the body has a series of adverse effects. Severe viral hepatitis secondary to bacterial infection with sepsis, respiratory and abdominal more common, followed by the urinary tract, digestive tract and biliary tract. Common pathogens are gram-negative bacilli, Alcaligenes, Pseudomonas aeruginosa, Salmonella, a few Gram-positive cocci. Gram-negative bacilli sepsis occurred, and more can not find the primary infection lesions. Clinical manifestations of fever, hypotension or shock, out
