降低外伤性前房积血的再次出血率的药物治疗已成为当前一个争论的课题。外伤性前房积血通常在首次积血后2～6天可发生再次出血。已报道未接受口服药物治疗的外伤性前房积血患者,再次出血率为0.4～35%。反复性前房积血易致角膜血染、周边虹膜前粘连、高眼压,而致视神经萎缩及视力减退。各家学者关于氨基己酸(aminocaproic acid)与强的松对再次前房出血的控制率报道不一。本试验的目的是比较口服氨基己酸与强的松对降低外伤性再次前房积血率作用的异同。 (一)对象和方法:所有病例均为钝挫伤 Medication to reduce the rate of rebleeding of traumatic hyphema has become a current topic of debate. Traumatic hyphema usually 2 to 6 days after the first hemorrhage may occur again bleeding. It has been reported that traumatic hyphema in patients who have not received oral medication has a recurrence rate of 0.4-35%. Repeated hyphema prone to cause corneal blood stained, peripheral adhesions before the iris, intraocular pressure, resulting in optic atrophy and vision loss. Various scholars on the aminocaproic acid (aminocaproic acid) and prednisone on the rate of re-bleeding control again reported different. The purpose of this experiment is to compare the similarities and differences between oral aminocaproic acid and prednisone to reduce the rate of traumatic rehospitalization.
