本文为13个医疗单位对颅内动脉瘤破裂后14日内用抗纤维蛋白溶酶制剂(6—氨基已酸或止血环酸)治疗的协作研究结果: 471例病人中,在出血后14天内的死亡率为11.6%,再出血率为12.7%。死亡多发生于出血后的第二周,大多数的再出血(61.7%)发生于初次出血后的第6与第11天之间。此即文献中提出6到14天死亡数字最高的主要原因。抗纤维蛋白溶酶制剂治疗通常需要3～5日方 This article is a collaborative study of 13 medical units treated with an anti-fibrinolytic agent (6-aminocaproic acid or tranexamic acid) within 14 days of intracranial aneurysm rupture: in 471 patients, within 14 days after bleeding The mortality rate was 11.6% and the rate of rebleeding was 12.7%. Death occurred mostly in the second week after bleeding, and most of the rebleeding (61.7%) occurred between the 6th and 11th days after the initial bleed. This is the main reason why the literature proposes the highest number of deaths from 6 to 14 days. Anti-fibrinolytic agents usually require 3 to 5 days for treatment
