亚低温治疗重型颅脑损伤病人纤维蛋白原和D-二聚体的变化及其临床意义

目的观察重型颅脑损伤病人在亚低温和常温治疗状态下纤维蛋白原(Fbg)与D-二聚体(D-dimer)差异及其临床意义。方法43例单纯性、重型颅脑损伤病人随机分为亚低温治疗组和常温组,两组性别、年龄、GCS评分无显著差异。伤后5次(6h、12h、24h、48h、72h)检测Fbg和D-dimer,并记录GOS评分。结果①两组Fbg值在伤后6h、12h、24h、48h差异显著,但伤后72h两组差异不显著。两组Fbg值在伤后6h均较高,常温组升高幅度更明显。两组Fbg值在伤后12h下降,亚低温组降低程度较常温组小。②两组D-dimer在伤后6h明显升高,常温组升高更明显;其在伤后6h、12h、24h差异显著,而在伤后48h、72h差异不显著。③亚低温组GOS评分优于常温组,差异显著。结论在颅脑损伤后4h即开始实施亚低温治疗能改善伤后的高凝状态,并减轻继发纤溶亢进。亚低温治疗缓解了凝血功能紊乱,是其能起到脑保护作用和改善治疗效果的机制之一。

The change and its clinical relevance of fibrinogen and D-dimer after sub-hypothermia therapy in patients with severe traumatic brain injury

Objective To observe and analyze the difference in fibrinogen (Fb) and D-dimer between the sub-hypothermia and normal temperature therapy groups and its significance in patients with severe traumatic brain injury. Methods The 43 patients who had simple severe head injury were randomly divided into two groups: sub-hypothermia group and normal temperature control group. There was no significant difference in gender, age and GCS score between the two groups. Fb and D-dimmer were detected and the GOS score reco...
