The aim of this study was to determine whether the routine use of sterile gloves when accessing central venous catheters (CVCs) affects the incidence of exogenous septicaemia in paediatric oncology patients. The 36-month study period ran prospectively from September 2000 to August 2003. During this time the routine use of sterile gloves for accessing CVCs was suspended. Sterile gloves were only used when obtaining blood samples from the line or injecting substances that required direct entry into the lumen with removal of line cap. Surveillance cultures of throat and rectum were obtained to detect carriage of potential pathogens. Exogenous septicaemia was defined as a blood stream infection due to microorganisms not carried by the patient in throat and/or rectum. The incidence of exogenous septicaemia following a change of practice of not routinely using sterile gloves for accessing lines was compared to the incidence of exogenous septicaemia in a historical control group. The number of exogenous septicaemia episodes per inpatient days with gloves and without gloves was calculated for the total number of episodes and for the first episode for each child. The relative incidence and 95% confidence intervals was also calculated for first and total episodes. For both, all episodes and first episodes there was no statistically significant difference in the incidence of exogenous septicaemia comparing the control and study patients. In summary, this study does not support or approve the use of sterile gloves when accessing CVCs in respect of exogenous septicaemia.
本研究的目的是确定在儿科肿瘤患者中,在使用中心静脉导管(CVC)时常规使用无菌手套是否会影响外源性败血症的发生率。这项为期36个月的前瞻性研究从2000年9月持续到2003年8月。在此期间,暂停了在使用CVC时常规使用无菌手套的做法。仅在从导管采集血样或注射需要直接进入管腔并取下导管帽的物质时才使用无菌手套。采集咽喉和直肠的监测培养物以检测潜在病原体的携带情况。外源性败血症定义为因患者咽喉和/或直肠中未携带的微生物引起的血流感染。将不常规使用无菌手套进行导管操作的做法改变后的外源性败血症发生率与历史对照组的外源性败血症发生率进行比较。计算每个患儿总发作次数和首次发作时戴手套和不戴手套情况下每住院日的外源性败血症发作次数。还计算了首次发作和总发作次数的相对发生率及95%置信区间。对于所有发作和首次发作,比较对照组和研究组患者,外源性败血症的发生率均无统计学显著差异。总之,就外源性败血症而言,本研究不支持或认可在使用CVC时使用无菌手套。
