交通事故幸存者围创伤期心率对创伤后应激障碍形成的预测作用

Heart rate in traffic accident survivors during peritraummatic period predicts the development of posttraumatic stress disorders

创伤后应激障碍(PTSD)的早期识别与干预是临床防治的关键,本实验考察交通事故幸存者急诊的心率与6个月后PTSD症状严重程度的关系,为PTSD的早期识别提供依据。实验检验了50起交通事故幸存者急诊中心率与创伤后1、3、6个月之后PTSD症状之间的关系。结果表明急诊心率可以预测6个月后临床诊断的PTSD症状严重程度,但对于1、3个月后PTSD症状则不能够进行预测。幸存者急诊心率与创伤后分离症状有着重大的关系,但与精神痛苦则没有显著相关。这些发现支持急诊心率可以作为PTSD早期识别的一个重要生理指标。

Posttraumatic stress disorder （PTSD） is characterized by distinctively temporal progression and emergence in the symptoms development, and all the symptoms are not created equally. The previous studies have been established that peritraumatic hyperarousal represents the key stress response and make a dominant role in the manifestation of other PTSD symptom clusters, and it is invited to examine which subtype of hyperaroual response in which time point during the peritraumatic periods can determine the natural progression of the PTSD symptom clusters and predict the development of PTSD. This small-scale study investigates the relationships between the heart rate of traffic accident survivors and posttraumatic stress disorder （PTSD） symptom severity at different time points atter trauma. Fifty motor vehicle accident survivors were assessed 1, 3, and 6 months post to the trauma.The results showed that the heart rate during peritraumatic period predicted clinician-rated PTSD symptom severity at 6 months but not at 1 or 3 months. These findings support the role of elevated heart rate as a predictor of chronic PTSD symptom severity.
