药用酚酞导致浑浊尿液的鉴别分析

The effects of medical phenolphthalein on the urine analysis and distinction

目的 :探讨药用酚酞对尿液分析的影响及其导致的浑浊尿的鉴别方法。方法 :参照有关文献 ,结合临床和体外实验 ,对含酚酞的尿液进行加热、加醋酸、氢氧化钠及显微镜检查。结果 :加热含有酚酞的碱性尿 ,红色消褪 ,浑浊度下降 ,水冲冷却红色恢复 ;加入醋酸或盐酸有微量气泡 ,加入过量酸 ,则出现白色浑浊 ;加热含酚酞的酸性尿 ,浑浊不消失 ,加入醋酸或盐酸 ,浑浊度无改变。滴加氢氧化钠尿液变成红色。结论 :口服酚酞可以导致病人出现浑浊尿 ,本研究提供的鉴别方法简单实用。

Objective: To study the effects of medical phenolphthalein on the urine analysis and distinctive method.Methods: Refering to literature concerned,combining clinical and external experiment,through heated to urine,added to acetic acid、hydrochloric acid and microscope test,the cloudy urine caused by phenolphthalein were distinguished.Results: Heated absic urine contained phenolphthalein,the red color disappeared,the cloudy degree dropped,after cooled down,the red color recovered.After added to acetic acid or hydrochloric acid,there was trace air bubble,if added to over acid,it would appear white cloudy,the acid urine contained phenolphthalein was heated,the cloudy didn't disappear,added to acetic acid or hydrochloric acid,the cloudy degree didn't change.Ater added to sodium hydroxide,the urine turned red color.Conclusion: To take orally phenolphthalein could make it difficult to distinguish patients urine especially the cloudy urine.It will be very important to strengthen the linking laboratories with clinical department.
