BACKGROUNDThe management of severe extravasation injuries is still controversial. Extravasation injuries can be treated in many ways.AIMTo present a series of patients with severe extravasation injuries due to infusion who were managed with ethacridine lactate dressing combined with localized closure and phototherapy.METHODSIn this study, we evaluated the data of eight patients, including six from the Department of Burn, one (with colorectal carcinoma) from the Veteran Cadre Department, and one (with leukemia) from the Hematology Department. Of these, three patients were male and five were female. Age of the patients ranged from 10 mo to 72 years, including two children (10 and 19 mo of age). In this study, the infusion was stopped immediately when the extravasation was identified. The extravasation event was managed routinely using a blocking solution. A ring-shaped localized closure was performed using the blocking agents. Moreover, ethacridine lactate dressing and phototherapy were applied for 3-5 d.RESULTSIn this study, the drugs contained in the infusates were iodixanol, norepinephrine, alprostadil, amino acids, fat emulsion, cefoselis, cefoxitin, and potassium chloride + concentrated sodium chloride. All of the patients achieved complete healing after treatment and no obvious adverse reactions were observed.CONCLUSIONThe treatment of severe extravasation injuries using a combination of localized closure, ethacridine lactate dressing, and phototherapy resulted in satisfactory outcomes in patients.
