BACKGROUND
Some hydrofluoric acid burns appear initially as only a slight wound, but patients may show dramatic changes within several hours. The extent of such burns are directly related to the concentration, amount, and duration of exposure.
CASE REPORT
A 64-year-old man sustained 44% total body surface burns after exposure to 30% hydrofluoric acid. Approximately 5 h after injury, he developed recurrent ventricular tachycardia and ventricular fibrillation which occurred in conjunction with long QT syndrome. In this case, the occurrence of hypocalcemia and especially hypomagnesemia played an important role in the development of long QT syndrome.
背景
一些氢氟酸烧伤最初可能仅表现为轻微创伤，但患者在数小时内可能会出现显著变化。此类烧伤的程度与氢氟酸的浓度、接触量及接触时间直接相关。
病例报告
一名64岁男性在接触30%氢氟酸后全身44%体表烧伤。受伤约5小时后，他出现了反复发作的室性心动过速和室颤，且伴有长QT综合征。在该病例中，低钙血症尤其是低镁血症的发生在长QT综合征的发展中起了重要作用。
