泌尿外科医护人员持续膀胱冲洗引流液颜色认知现状调查

Recognition of Drainage Fluid Color of Continuous Bladder Irrigation for Doctors and Nurses of Urological Department

目的了解医护人员对持续膀胱冲洗引流液颜色的认知情况。方法采取自行设计的持续膀胱冲洗引流液色阶卡及问卷,调查荆州市4所医院泌尿外科60名医护人员对持续膀胱冲洗引流液颜色的认知状况。结果对色阶卡所示的颜色进行描述,除5号色(红细胞浓度2%)被一致描述为鲜红色外,其他色号至少有2～4种认知结果,且同一认知结果色差跨度大;调节冲洗速度时选择的引流液颜色不一致;50%的医护人员不能根据引流液的颜色判断出血量的多少,50%对出血量的判断结果存在较大差异。结论医护人员对引流液颜色的判断和描述缺乏统一的客观标准,多凭主观感觉判断,不能准确客观动态地描述患者的病情变化,影响了医护人员对冲洗速度的正确调节,降低了健康教育效果。应尽早研制出持续膀胱冲洗引流液比色卡作为判断引流液颜色的客观标准,并规范持续膀胱点滴冲洗及引流情况的观察记录方式。

Objective To understad the recognition of drainage fluid color of continuous bladder irrigation among medical staff. Methods A self-designed colorchecker and questionnaire were applied to 60 medical staff in 4 urological departments for the recognition of drainage fluid color. Results Except Color No. 5 （erythrocyte concentration at 2%） viewed unanimously as bright red, oth- er colors had 2~4 recognition results with great significant chromatic aberration. All the medical staff selected different fluid color on irrigation speed adjustment, 50% of them were unable to evaluate the blood volume based on the fluid color, 50% varying significantly in the blood volume evaluation. Conclusion The recognition of drainage fluid color of continuous bladder irrigation is not based on any objective standards but on subjective cognition, which fails to correctly regulate the irrigation speed. Therefore, colorimetric card should be established, and standard for color recognition recording styles for bladder drop irrigation and drainage should be specified.
