超限制性红细胞 (RBC) 输血策略 (血红蛋白<7 g/dL) 在严重烧伤患者中没有显示任何不良影响. 然而,低于6g/dL的值显著增加了死亡率,这表明红细胞输血的安全下限.
科学领域:
- 创伤外科 手术 创伤外科
- 关键护理医学 关键护理医学
- 血液学 血液学 血液学
背景情况:
- 由于血液产品短缺,需要对严重烧伤患者的输血策略进行评估.
- 由于稀缺性,已经实施了超限制性红细胞 (红细胞) 输血 (血红蛋白<7 g/dL或<6 g/dL).
- 这些策略的预后影响需要彻底调查.
研究的目的:
- 为了研究超限制性红细胞输血在严重烧伤患者 (总体表面积≥50%) 的预后影响.
- 为了比较超限制性 (<7 g/dL) 和限制性输血组之间的结果.
- 进一步分析基于输血值 (<6 g/dL vs. 6-7 g/dL) 的超限制性组内的结果.
主要方法:
- 对271名严重烧伤患者进行了回顾性多中心队列研究 (2016年1月至2022年6月).
- 患者分为超限制性 (<7 g/dL) 和限制性输血组.
- 倾向性得分匹配 (PSM) 和多变量分析用于调整混因素. 应用了修改Poisson和线性回归.
主要成果:
- 超限制性组的红细胞显著减少 (11.5对17.3单位,p=0.004).
- 在PSM后和调整后,两组之间没有发现死亡率,感染风险或住院时间的显著差异 (p>0.05).
- 在超限制性组中,值<6g/dL与死亡率显著增加有关 (53.1%对21.3%,p=0.001) 与6-7g/dL相比.
结论:
- 在血液短缺期间,对于严重烧伤的患者,超限制性红细胞输血的临界值<7g/dL是可以接受的.
- 输血值<6g/dL与死亡率增加有关,应避免使用.
- 仔细考虑输血门对于优化广泛烧伤护理结果至关重要.
