目的:依靠传统的生命体征(TVS)来识别受伤后危及生命的休克可能并不可靠,尤其是对于老年患者。休克指数 (SI) 定义为心率除以收缩压 (SBP),可能是比 TVS 更好的损伤后早期休克指标。对于老年受伤患者,将年龄乘以 SI(年龄× SI)可能更好。我们假设,与 TVS 相比,年龄× SI 可以更好地预测老年患者(年龄 > 55 岁)的 48 小时死亡率,而对于年轻患者(年龄≤ 55 岁),SI 将比 TVS 更好地预测。 方法:对国家创伤数据库 8.1 版进行查询,了解 2007 年期间发生的 18 至 81 岁患者的钝性非神经性损伤事件。比较年轻和老年患者的 TVS、SI 和年龄 × SI 的受试者工作特征曲线 (AUC) 下面积,以预测 48 小时死亡率。结果:总共识别出 189,574 起事件。总体 48 小时死亡率为 1.18%。对于年轻患者,SBP(AUC,0.654)和SI(AUC,0.655)在预测48小时死亡率方面没有差异。对于老年患者,与心率(AUC,0.626;p<0.0001)、SBP(AUC,0.657;p<0.0002)或SI(AUC,0.684;p<0.008)相比,年龄×SI(AUC,0.693)是48小时死亡率更好的预测因子。结论:TVS对于术后休克的预测因子不充分。非神经性钝性损伤。使用年轻人的 SI 和老年人的年龄 × SI 来识别钝性损伤后有早期死亡风险的患者可能会导致更早的明确治疗。
Objective:Reliance on traditional vital signs (TVS), particularly in older patients, to identify life-threatening shock after injury may be unreliable. Shock index (SI), defined as heart rate divided by systolic blood pressure (SBP), may be a better indicator of early shock after injury than TVS. Multiplying age by SI (age× SI) may be better in older injured patients. We hypothesized that age× SI would be a better predictor of 48-hour mortality in old patients (age,> 55 years) compared with TVS, whereas for young patients (age,≤ 55 years), SI would be a better predictor than TVS.Methods:Version 8.1 of the National Trauma Data Bank was queried for incidents of blunt, non-neurologic injury occurring during 2007, to patients aged 18 to 81 years. Areas under the receiver operating characteristic curves (AUC) were compared for TVS, SI, and age× SI in young and old patients for predicting 48-hour mortality.Results:A total of 189,574 incidents were identified. Overall 48-hour mortality was 1.18%. For young patients, there was no difference between SBP (AUC, 0.654) and SI (AUC, 0.655) for predicting 48-hour mortality. For old patients, age× SI (AUC, 0.693) was a better predictor of 48-hour mortality compared with heart rate (AUC, 0.626; p< 0.0001), SBP (AUC, 0.657; p< 0.0002), or SI (AUC, 0.684; p< 0.008).Conclusion:TVS are inadequate predictors of shock after non-neurologic blunt injury. Using SI in the young and age× SI in old to identify patients at risk for early mortality after blunt injury could result in earlier definitive treatment.
