BACKGROUND
Post-traumatic amnesia is considered to be the best single indicator of the severity of closed head injury. Usually, it has been estimated retrospectively. For practical reasons this also tends to be the most common clinical method. It has been argued that prospective assessment is more accurate and reliable, but this has never been evaluated empirically in severe head injury.
METHODS
Post-traumatic amnesia was initially assessed prospectively and later retrospectively by a separate observer in the same patients.
RESULTS
The correlation between the two methods was high. In addition, both measures significantly correlated with other measures of severity of brain injury and with measures of outcome.
CONCLUSION
Retrospective measurement of post-traumatic amnesia is a valid method.
背景
创伤后遗忘被认为是闭合性颅脑损伤严重程度的最佳单一指标。通常，它是通过回顾性评估得出的。出于实际原因，这也往往是最常用的临床方法。有人认为前瞻性评估更准确可靠，但在严重颅脑损伤中从未进行过实证评估。
方法
由同一位观察者对同一组患者的创伤后遗忘情况最初进行前瞻性评估，随后进行回顾性评估。
结果
两种方法之间的相关性很高。此外，这两种测量方法均与脑损伤严重程度的其他测量指标以及预后指标显著相关。
结论
创伤后遗忘的回顾性测量是一种有效的方法。
