目的探讨红细胞分布宽度(RDW)在急危重症患者预测死亡风险中的应用。方法选择80例死亡的急危重症患者作为A1组,对其进行回顾分析,收集死亡前1~2周的血常规数据;另随机选择80例目前正在住院治疗非危重的患者作为A2组,选择在查体中心来院查体的健康者80例作为A3组,两组均在空腹12 h后的第2天早晨采集静脉血检测血常规。比较三组RDW变化情况。结果 A1组RDW明显高于A2组、A3组,差异有统计学意义(t=12.679、19.869,P<0.05),A2组RDW高于A3组,差异有统计学意义(t=21.789,P<0.05)。结论 RDW的检测可用于多种不同的疾病患者死亡风险评估及预后判断。
Objective To investigate the application of RDW to predict the risk of death in critically ill patients. Methods Eighty critically ill critically ill patients who died were selected as group A1 and analyzed retrospectively to collect blood routine data 1 to 2 weeks before death. Another 80 patients were selected randomly as inpatients with non-critically ill patients as A2 group. In the physical examination center to check the physical health of 80 cases as the A3 group, two groups were in the fasting 12h after the morning of the second day to collect venous blood test blood. Comparison of RDW changes in three groups. Results The RDW in group A1 was significantly higher than that in group A2 and group A3 (t = 12.679, 19.869, P <0.05). The RDW in group A2 was significantly higher than that in group A3 (t = 21.789, P < 0.05). Conclusion The detection of RDW can be used to evaluate the risk of death and prognosis in many different diseases.
