摘要
目的为量化评估小儿重症监护病房(PICU)环境清洁水平、规范清洁流程、探索环境清洁效果的监测方式提供依据。方法基于手接触频率、人员活动以及与病患接触程度,选择PICU内22种医疗器械和环境表面,应用三磷酸腺苷(ATP)生物荧光技术,比较了清洁前、清洁后即刻、2、4、8h的表面相对荧光强度(Relative LightUnits,RLU)值。结果护士桌板、简易呼吸器、监护仪按钮、输液泵面板、加压输液袋的充气皮球、床头桌板和尺子表面RLU值>500;清洁可有效降低医疗器械和环境表面RLU值,但清洁后监护仪按钮、输液泵面板、床头桌板和简易呼吸器等RLU值上升较快,清洁后4hRLU值>500;血气分析仪按钮、进样口和操作台面测定表面RLU值>15 000,交叉污染风险高。结论 ATP荧光法作为检测工具能对医院环境清洁水平做出客观、实时的监测,量化的监测数据为改善术后监护病房内环境清洁水平提供了基础性资料。
OBJECTIVE To quantitatively evaluate the environmental surface cleanliness in the pediatrics intensive care unit（PICU） of the hospital and to monitor the efficacy of the cleaning methods used and standardize the cleaning procedure.METHODS A total of 22 different kinds of environmental surfaces in PICU,Fuwai Heart Hospital Cardiovascular Institute were chosen based on the hand contact frequency and contamination risk level.Their cleanliness was evaluated using an ATP bioluminescence method.RESULTS It was shown that the average ATP values of simple respirator,physiological bedside monitor panel,infusion pump panel,pressurized infusion bag ball and nurse′s table were 500 relative light units（RLU） before the cleaning,indicating high contamination risk,while the RLUs of all environmental surfaces reduced to 500 after cleaning.However,ATP values of physiological bedside monitor panel,infusion pump panel,simple respirator and bedside table showed a rapid increase after the cleaning and RLU readings reached 500 4 hours after cleaning.It was surprising to discover that the average RLU of a blood-gas analyzer panel,screen and injection port were 15 000.CONCLUSION It is concluded that in a PICU the use of an ATP method could provide quantitative information of cleaning efficacy and ATP trends,to allow the identification of environmental surfaces that require the additional cleaning or cleaning schedule amendments.
