Free fatty acids (FFAs) and triglycerides (TGs) are altered postburn, but whether these alterations are associated with postburn outcomes is not clear.
The aim of the present study was to analyze lipid metabolic profiles in pediatric burn patients and to correlate these profiles with patient outcomes and hospital courses.
We conducted a prospective cohort study at an academic pediatric hospital burn center.
Our study included 219 pediatric burn patients.
Patients were stratified according to their plasma TG and FFA levels. Main patient outcomes, such as postburn morbidity and mortality, and clinical metabolic markers were analyzed.
All groups were similar in demographics and injury characteristics. Patients with elevated TGs had significantly worse clinical outcomes associated with increased acute-phase protein synthesis indicating augmented inflammation and hypermetabolism, whereas increased FFAs did not seem to profoundly alter postburn outcomes.
Elevated TGs, but not FFAs, postburn are associated with worsened organ function and clinical outcomes.
烧伤后游离脂肪酸（FFAs）和甘油三酯（TGs）会发生改变，但这些改变是否与烧伤后结局相关尚不清楚。
本研究旨在分析小儿烧伤患者的脂代谢谱，并将这些谱与患者结局和住院过程相关联。
我们在一家学术性儿科医院烧伤中心进行了一项前瞻性队列研究。
本研究纳入了 219 例小儿烧伤患者。
根据患者的血浆 TG 和 FFA 水平对其进行分层。分析主要患者结局，如烧伤后发病率和死亡率，以及临床代谢标志物。
所有组在人口统计学和损伤特征方面均相似。TG 升高的患者临床结局明显较差，与急性期蛋白合成增加相关，表明炎症和高代谢增强，而 FFA 升高似乎并未显著改变烧伤后的结局。
烧伤后 TG 升高而非 FFA 升高与器官功能和临床结局恶化相关。
