The lactate-to-albumin ratio (LAR) is associated with mortality in pediatric traumatic brain injury (TBI) patients.
2
In a study of 98 pediatric TBI patients, the overall mortality rate was found to be 9%.
3
Non-survivors exhibited significantly higher PRISM III scores and lower pediatric Glasgow Coma Scale scores compared to survivors.
4
LAR values were notably higher in non-survivors, indicating its potential as a prognostic marker for mortality.
5
This study is the first to evaluate LAR as a predictor of mortality in pediatric TBI, despite its limitations.
