The extravasation of potassium chloride will cause serious harm, especially if it is not diagnosed or treated promptly. Objective:to report the clinical course of a patient who was suffering a potassium extravasation and to discuss steps that can be done to decrease the chances of this event from occurring in other patients.
After discontinuation of infusion device and withdrawal of intravenous catheter, wet packing with magnesium sulfate and local injection of papaverine and lidocaine were applied.
After 11 days, the extravasation injury had recovered.
To avoid a repeat of such an adverse event, proper sites for administering, accurate dilution of potassium chloride solutions, close observation, and increased awareness of trained personnel of extravasation dangers are vital. Once extravasation occurs, timely wet application with magnesium sulfate and local injection of papaverine and lidocaine may have been useful in producing a favorable recovery.
氯化钾外渗会造成严重危害，尤其是未及时诊断或治疗时。目的：报告一例氯化钾外渗患者的临床病程，并探讨可采取哪些措施降低其他患者发生此类事件的几率。
停止输液装置并拔除静脉导管后，采用硫酸镁湿敷以及局部注射罂粟碱和利多卡因。
11天后，外渗损伤恢复。
为避免此类不良事件再次发生，选择合适的给药部位、准确稀释氯化钾溶液、密切观察以及提高受过培训人员对外渗危险的认识至关重要。一旦发生外渗，及时用硫酸镁湿敷以及局部注射罂粟碱和利多卡因可能有助于实现良好恢复。
