目的探讨手术患者经手术感染乙型肝炎病毒(HBV)的防护方法。方法在HBV传染性定量和测定HBV经手术传播感染阈值的基础上,探讨手术患者经手术感染HBV的防护方法。结果 HBV经手术传播的感染阈值为105ID/ml,HBsAg阳性、HBeAg阴性和阳性者中传染源比率分别为19.2%、3.2%和83.9%;HBV经双层手套传播的防护阈值为106ID/ml,HBsAg阳性和HBeAg阳性者中传染源比率分别为14.7%和67.8%;以103ID/ml为禁止外科医师做手术的淘汰阈值。结论手术患者感染HBV的主要传染源是外科医师,禁止可能成为传染源的外科医师从事具有侵入性的医疗操作是有效的防护方法,如何识别外科医师中的传染源是制定具体防护措施的关键所在。
Objective To investigate the surgical protection of hepatitis B virus (HBV) in surgical patients. Methods Based on the quantitative detection of HBV and the threshold of HBV infection by surgery, the protective methods of surgical infection of HBV in surgical patients were explored. Results The infection threshold of HBV transfusion was 105ID / ml. The infection rates of HBsAg positive, HBeAg negative and positive were 19.2%, 3.2% and 83.9% respectively. The protective threshold of HBV transmitted by double glove was 106ID / ml, The ratio of infection sources in HBsAg-positive and HBeAg-positive patients was 14.7% and 67.8%, respectively; the threshold for elimination of surgeons surgery was 103ID / ml. Conclusions The main source of infection for surgical patients infected with HBV is the surgeon, the prospective surgeon forbidden to be a source of infection is an effective method of protection against invasive medical procedures and how to identify the source of infection among surgeons is the key to developing specific protective measures .
