摘要 目的动态观察外科重症脓毒症患者血清血乳酸及D-二聚体水平与预后的关系。方法回顾性分析55例符合重症脓毒症标准的患者,比较8、16、24、48、72和168 h的血乳酸变化和24、72、168 h的D-二聚体变化。结果其中34例存活,21例死亡,死亡率为38.2%,均死于多器官功能衰竭。34例存活组血乳酸48 h内均达到正常,而21例死亡组直至第168 h仍明显高于存活组和正常值(P<0.05)。死亡组24 h D-二聚体水平比存活组明显升高(为正常值的5倍)(P<0.05),在72和168 h两组无显著差异(P>0.05),但两组D-二聚体仍明显升高(为正常值的2.5倍)。若以24 h血乳酸和24 hD-二聚体预测死亡能力作ROC曲线,24 h血乳酸和D-二聚体的预测死亡能力相当。结论动态监测1周内血乳酸水平是判断重症脓毒症患者预后的一个重要指标,血乳酸48 h内降至正常,预后良好;随后的血乳酸仍高于正常,预后差。24 h血乳酸水平与24 h D-二聚体水平预测死亡能力相当。
