Risk factors for surgical site infections in patients with hepatobiliary operations

Abstract:

ObjectiveTo study the risk factors for surgical site infections (SSI) in patients with hepatobiliary operations, and provide the basis for preventing SSI.MethodsTargeted monitoring method was adopted to study the incidence rate of hepatobiliary SSI, the related factors for hepatobiliary SSI were analyzed with univariate and multivariate Logistic regression analysis model, which include preoperative hospital days, diabetes mellitus, plasmaalbumin, the length of operation process, surgical approach, ASA score, direction of incision, incision length, blood loss during operation process, drainage days, postoperative complication， et al.ResultsThe incidence rate of hepatobiliary SSI was 11.74% (35/298), 24 cases (68.57%) acquired infections during hospitalization period, 11 cases (31.43%) acquired infections after discharge. Logistic regression analysis showed that the independent  risk factors of hepatobiliary SSI included postoperative complications such as fatty liquefaction ,incision fissuration,  length of operation and drainage days. ConclusionMultiple factors contribute to hepatobiliary SSI , comprehensive preventive measures should be taken to control the incidence rate of hepatobiliary SSI.
