Hyperkalaemia in Trauma

This set includes retrospectively collected data from a Level-1 trauma centre in Austria.
With these data, we conducted a retrospective cohort study on adult patients with traumatic bleeding admitted to a European Major Trauma Centre between January 2016 and December 2021. Patients were classified according to their serum potassium levels on arrival, and relevant clinical parameters between non-hyperkalaemic and hyperkalaemic patients were compared.
Among the 83 patients in this study, 11 (13.3%) presented with hyperkalaemia on arrival. The median shock index showed a higher tendency in the hyperkalaemic group. Hyperkalaemia was found to be more prevalent among younger patients who sustained penetrating trauma. Mortality rates were higher in the hyperkalaemic group, but the difference was not statistically significant.
Our results suggest that hyperkalaemia is prevalent in bleeding trauma patients on hospital arrival pre-transfusions, suggesting a more severe illness. Our findings provide insights into the pathophysiology and characteristics of hyperkalaemia in bleeding trauma patients. Further studies are required to investigate the mechanisms by which hyperkalaemia contributes to mortality in haemorrhagic shock patients.

本数据集包含从奥地利一家一级创伤中心回顾性收集的数据。利用这些数据，我们对2016年1月至2021年12月期间被收入欧洲主要创伤中心的成人创伤性出血患者进行了回顾性队列研究。患者根据到达时的血清钾水平进行分类，并比较了非高钾血症患者与高钾血症患者的相关临床参数。在该研究中，83名患者中，有11名（占13.3%）在到达时出现高钾血症。高钾血症组的休克指数显示出更高的倾向。研究发现，高钾血症在遭受穿透性创伤的年轻患者中更为普遍。高钾血症组的死亡率较高，但差异不具有统计学意义。我们的研究结果提示，高钾血症在到达医院且在输血前出血创伤患者中普遍存在，表明病情更为严重。本研究揭示了出血创伤患者高钾血症的病理生理学特征。为进一步探究高钾血症如何导致失血性休克患者的死亡率，需要开展进一步的研究。
