Syringes (N = 426), ventilator machine swabs (N = 202) and intravenous (IV) fluid administration sets (N = 47) from 101 surgical cases were evaluated for bacterial contamination. Cultures from the external surface of syringe tips and syringe contents were positive in 46% and 15% of cases, respectively. The same bacterial species was cultured from both ventilator and syringe in 13% of cases, and was also detected in the IV fluid administration set in two cases. A significant association was found between emergency cases and contaminated syringes (odds ratio 4.5, 95% confidence interval 1.37-14.8; P = 0.01). Other risk factors included not using gloves and failure to cap syringes.
对101例外科手术病例中的注射器（n = 426）、呼吸机拭子（n = 202）和静脉输液器（n = 47）进行了细菌污染评估。注射器尖端外表面和注射器内容物的培养分别在46%和15%的病例中呈阳性。13%的病例中，呼吸机和注射器培养出相同的细菌种类，在两例静脉输液器中也检测到该细菌。发现急诊病例与受污染注射器之间存在显著关联（比值比4.5，95%置信区间1.37 - 14.8；P = 0.01）。其他风险因素包括未戴手套和未给注射器盖帽。
