目的:构建持续膀胱冲洗（CBI）引流液颜色评估工具，探索其临床价值。方法:通过文献回顾、专家会议、实践研制等方法构建CBI引流液颜色评估工具（暂定版），并对其进行一致性检验及完善，形成CBI引流液颜色评估工具。采用便利抽样法选取2020年4—5月于苏州大学附属第一医院行经尿道前列腺电切术（TURP）的良性前列腺增生患者，根据工具的评估方法对患者的引流液颜色进行评估和记录。结果:CBI引流液颜色评估工具包括6个色阶，与此相对应的潘通色卡代码分别为503C、3519C、701C、702C、710C、1807C，血液浓度分别为0.125%、0.5%、1.0%、2.0%、4.0%和8.0%。应用该工具对29例TURP术后患者进行引流液颜色评估，每次评估耗时（5.12±2.41）s；当色阶>2号时可出现膀胱痉挛、血块堵管等并发症。结论:CBI引流液颜色评估工具构建方法科学可靠，可为评估CBI引流液颜色提供依据，可辅助医护人员快捷地评估引流液颜色并发现异常色阶。“,”Objective:To construct a color assessment tool for continuous bladder irrigation (CBI) drainage fluid and to explore its clinical value.Methods:The color assessment tool for CBI drainage fluid (tentative version) was constructed through literature review, expert meetings and practical development, and its consistency was tested and the tool was improved to form a color assessment tool for CBI drainage fluid. Convenience sampling was used to select patients with benign prostatic hyperplasia who underwent transurethral resection of the prostate (TURP) in the First Affiliated Hospital of Soochow University from April to May 2020. According to the assessment method of the tool, the patient's drainage fluid color was evaluated and recorded.Results:The color assessment tool for CBI drainage fluid included 6 color scales, and the corresponding Pantone color card codes were 503C, 3519C, 701C, 702C, 710C, 1807C respectively, and the blood concentration was 0.125%, 0.5%, 1.0%, 2.0%, 4.0% and 8.0% respectively. The tool was used to evaluate the drainage fluid color in 29 patients after TURP. Each evaluation took (5.12±2.41) s; when the color scale was greater than number two, complications such as the bladder spasm and blood clot blockage occurred.Conclusions:The construction method of color assessment tool for CBI drainage fluid is scientific and reliable, which can provide a basis for evaluating the CBI drainage fluid color, and can assist medical and nursing staff to quickly evaluate the drainage fluid color and find abnormal color scales.
