PINK URINE SYNDROME: A RARE COMPLICATION OF PROPOFOL INFUSION - A CASE REPORT

Pink urine syndrome (PURS) is a rare and poorly documented complication that can occur during infusion of propofol, an intravenous anesthetic commonly used in general anesthesia and sedation. This phenomenon is characterized by abnormal pink or red coloration of the urine, often associated with an absence of severe clinical symptoms. Although its origin remains partially understood, it is suggested that the discoloration arises from the presence of propofol metabolites or drug degradation products. This article presents a clinical case illustrating this complication, outlining possible pathophysiological mechanisms, risk factors, as well as clinical management and implications for anesthetic practice.

粉红色尿综合征（Pink urine syndrome, PURS）是一种罕见且文献记载匮乏的并发症，可在丙泊酚（propofol）——一种常用于全身麻醉与镇静操作的静脉麻醉药——输注期间发生。该病症以尿液出现异常粉红色或红色着色为特征，通常无严重临床症状。尽管其发病机制尚未完全阐明，目前认为该尿液变色现象源于丙泊酚代谢产物或药物降解产物的存在。本文报道一例该并发症的临床病例，阐述了可能的病理生理机制、危险因素，以及临床管理方案与麻醉实践中的相关启示。
