Injured patients presenting with hypothermia, acidosis and coagulopathy have been identified at high risk of death. This study aimed to describe the presentation, management and outcome of major trauma patients presenting with the 'triad of death' and identify ways to improve survival.
A retrospective, explicit chart review was undertaken on patients presenting to a level I adult major trauma centre with the 'triad of death'. These patients presented directly from the scene, were coagulopathic (international normalised ratio (INR) >1.5), hypothermic (temperature <35°C) and acidotic (pH <7.2) on arrival.
There were 90 patients over an 8-year period, with an overall mortality of 47.8%. No significant differences were observed among demographics and injury severity scores between survivors and non-survivors. Extremes of systolic blood pressure and heart rate, a high activated partial thromboplastin time activated partial thromboplastin time, low fibrinogen counts, pH, bicarbonate, base excess and haemoglobin were present among survivors. There were no survivors in our cohort with an initial INR greater than 3.2. Survivors received significantly lower volumes of packed red blood cells.
There has been little change in mortality over time in this subgroup of major trauma patients. While the presence of the triad alone does not determine futility, there were no survivors over 8 years with extreme coagulopathy with concurrent hypothermia and acidosis.
体温过低、酸中毒和凝血病的受伤患者已被确定为高死亡风险。本研究旨在描述出现“三联征”的严重创伤患者的表现、治疗和结局,并确定提高生存率的方法。
对在 I 级成人严重创伤中心就诊的出现“三联征”的患者进行回顾性、明确的图表审查。这些患者直接从现场送来,入院时即出现凝血功能障碍(国际标准化比值(INR)>1.5)、体温过低(<35°C)和酸中毒(pH 值<7.2)。
在 8 年期间有 90 名患者,总死亡率为 47.8%。幸存者和非幸存者在人口统计学和损伤严重程度评分方面无显著差异。在幸存者中存在血压和心率的极端值、高激活部分凝血活酶时间、低纤维蛋白原计数、pH 值、碳酸氢盐、碱剩余和血红蛋白。在我们的队列中,没有初始 INR 大于 3.2 的幸存者。幸存者接受的红细胞浓缩物量明显较少。
在这个严重创伤患者亚组中,随着时间的推移,死亡率几乎没有变化。虽然三联征本身并不能确定治疗无效,但在 8 年的时间里,没有凝血功能严重障碍伴体温过低和酸中毒的幸存者。
