甲醛加液台对减少手术室医护人员甲醛暴露的效果研究

The clinical effect of formaldehyde filling table on reducing formaldehyde exposure of medical staff in operating room

目的探讨自行设计的甲醛加液台对改善手术室标本间护士甲醛暴露的效果。方法采用自身前后对照试验,将江西省某三级甲等医院2022年6月工作日手术标本室内空气质量设为对照组,2022年7月空气质量设为实验组。对照组采用传统加仑桶取液,实验组采用自主研制的电动甲醛加液装置进行取液。比较2组标本间内甲醛浓度、总挥发性有机物(total volatile organic compounds,TVOC)及空气质量指数(air quality index,AQI)及操作中鼻眼刺激程度,护士标本处理所用时间。结果实验组甲醛值、AQI、TVOC均低于对照组;标本室内甲醛值、TVOC值、AQI值在不同甲醛存储工具下不同时间的变化趋势不同(P<0.01)。实验组中护士重度鼻眼刺激次数均小于对照组(P<0.01),且标本处理所用时间也少于对照组(P<0.01)。结论采用医用甲醛加液台进行手术室标本间的甲醛溶液存储及取用,密闭性强,同时提供了便捷式的液体用量选择,缩短了护士操作时间,减少了标本室内甲醛暴露风险,效果良好。

Objective To explore the effect of self-designed formaldehyde filling table on reducing the formaldehyde exposure of nurses in the surgical specimen room.Methods Using a before and after self control study,the air quality of the surgical specimen room on weekdays in June 2022 in a A tertiary hospital in Jiangxi province was set as the control group,and the air quality in July was set as the experimental group.The control group adopted traditional gallon bucket for liquid extraction,and the experimental group used the self-developed electric formaldehyde filling table for liquid extraction.The concentration of formaldehyde,total volatile organic compounds(TVOC),air quality index(AQI),degree of nasal,eye irritation during nurse operation,and the time spent by nurses in specimen processing were compared between 2 groups.Results The formaldehyde concentration,AQI,and TVOC of the experimental group were lower than those of the control group;The change trends of formaldehyde concentration,TVOC,and AQI in different formaldehyde storage tools were different at different times(P<0.01).The frequency of severe nasal of nurses in the experimental group was less than that in the control group(P<0.01),and the time of specimen processing in the experimental group was also less than that in the control group(P<0.01).Conclusion The use of medical formaldehyde filling table for formaldehyde solution storage and access between specimens in the operating room has strong airtightness and provides convenient choice of liquid dosage,shortens the operation time of nurses,reduces the risk of formaldehyde exposure in the specimen room,and has good effects.
