概括
经过广泛的烧伤手术后,在术后第三天 (POD3) 的乳酸水平升高预示着临床恶化. 在烧伤患者中持续高的POD3乳酸表明风险较高,指导早期干预.
科学领域:
- 烧伤手术
- 创伤重症护理
- 代谢压力生物标志物
背景情况:
- 乳酸的升高表明组织的低 perfusion 和代谢压力.
- 在接受早期切除和移植 (EEG) 的严重烧伤患者中,乳酸的预后值尚不清楚.
- 这项研究评估了手术前乳酸水平以预测EEG后的临床恶化.
研究的目的:
- 评估术前乳酸水平的预后意义.
- 确定乳酸水平,预测广泛烧伤患者的脑电图后的临床恶化.
- 探索乳酸作为早期风险评估标志物的有用性.
主要方法:
- 成年烧伤患者的回顾性队列研究 (≥50%的TBSA或≥20%的全厚烧伤).
- 根据SOFA分数的变化将患者分为恶化和不恶化组.
- 进行单变量/多变量逻辑回归和ROC曲线分析.
主要成果:
- 37. 8% 的患者出现恶化.
- 恶化组的烧伤指数更高,手术区域更大,输血量更大.
- 持续升高的POD3乳酸水平 (2. 88 ± 0. 65 mmol/ L与2. 27 ± 0. 68 mmol/ L) 与恶化显著相关 (OR 2. 97, p=0. 031).
- 乳酸POD3水平显示出最高的区分性能 (AUC=0. 761).
结论:
- 术后第3天的乳酸水平与EEG后严重烧伤患者的临床恶化有显著关联.
- POD3乳酸可以作为早期风险分层的有价值标志物.
- 使用POD3乳酸可为高风险患者提供及时的支持性干预.

Burn Injuries
2.8K
Burn injuries occur when the skin and underlying tissues are damaged due to exposure to heat, electricity, chemicals, radiation, or friction. They can vary in severity, from minor superficial burns to severe deep burns that can be life-threatening.
The damage results in the death of skin cells, which can lead to a massive loss of fluid. Dehydration, electrolyte imbalance, and renal and circulatory failure follow, which can be fatal. Burn patients are treated with intravenous fluids to offset...
