Hepatitis B virus (HBV) infection, an occupational risk to anaesthetists, varies widely in incidence throughout the world. This study was undertaken to define the prevalence of previous HBV infection in anaesthesia personnel in the teaching hospitals of metropolitan Vancouver. Participants donated a blood sample and completed a questionnaire. Overall participation rate was 90.4 per cent. No participants were HBV carriers. Ten of 83 anaesthetists (12 per cent) had antibodies to HBV while all anaesthesia residents were seronegative. Anaesthetists with HBV antibodies tended to be either older or foreign born. Standard precautions taken by anaesthetists such as use of preoperative questioning of a patient's hepatitis status or the use of gloves when handling body fluids of a suspected or proven HBV carrier could not be shown to affect this seropositivity rate. This study, consistent with others, suggests that anaesthetists are at risk for acquiring HBV infection from occupational exposure. This risk appears to be somewhat less than that for surgeons, dentists, and staff of dialysis and urban emergency units.
乙型肝炎病毒（HBV）感染是麻醉医生面临的职业风险，其发病率在世界各地差异很大。本研究旨在确定大温哥华地区教学医院麻醉人员既往HBV感染的患病率。参与者捐献了一份血样并填写了一份问卷。总体参与率为90.4%。没有参与者是HBV携带者。83名麻醉医生中有10名（12%）有HBV抗体，而所有麻醉住院医生血清学检测均为阴性。有HBV抗体的麻醉医生往往年龄较大或出生在国外。无法证明麻醉医生采取的标准预防措施，如术前询问患者的肝炎状况或在处理疑似或确诊HBV携带者的体液时使用手套，会影响这种血清阳性率。这项研究与其他研究一致，表明麻醉医生有因职业暴露而感染HBV的风险。这种风险似乎略低于外科医生、牙医以及透析和城市急救单位的工作人员。
