对1990～1993年住我院普外科患者5297，例进行乙型肝炎病毒（HBV）感染的血清流行病学统计调查。结果：HBV感染者3736例，总感染率70．5％，HBsAg、抗-HBs及抗-HBc的阳性率分别为19．4％、35．9％和41．1％，明显高于一般人群。而肝胆胰系统疾病患者的HBV总感染率、HBsAg及抗-HBc的阳性率分别为80．3％、34．2％和56．1％，亦明显高于外科其它系统疾病患者。因此，应重视有HBV感染的普外科患者的围手术期处理。 Serum epidemiological survey of hepatitis B virus (HBV) infection was performed on 5297 patients admitted to our hospital from 1990 to 1993. Results: Among 3736 HBV infected patients, the total infection rate was 70.5%, the positive rates of HBsAg, anti-HBs and anti-HBc were 19.4%, 35.9% and 41.1% respectively, significantly higher than those of the general population . The positive rates of HBV infection, HBsAg and anti-HBc in patients with hepatobiliary and pancreatic diseases were 80.3%, 34.2% and 56.1%, respectively, which were significantly higher than those in other surgical diseases. Therefore, attention should be paid to the perioperative management of general surgical patients with HBV infection.
