ABSTRACT
BACKGROUND/PURPOSE:
Serum lactate measurement has a predictive value in adult trauma. To date, there has been no prospective analysis of the predictive value of admission serum lactate in pediatric trauma.METHODS:
Admission serum lactate was prospectively measured over a two year period on all children under age 15 years who met trauma alert criteria at an urban Level 1 trauma center. Elevated serum lactate (>2.0 mmol/L) was correlated with Injury Severity Scores (ISS), injury types, and hospital outcomes.RESULTS:
A total of 277 injured children with admission lactate measurements were evaluated. Patients with elevated lactate had higher mean ISS than those with normal lactate (12.8 vs. 5.1, p<0.01), and increased need for intubation, major procedures and ICU admission. Elevated lactate was associated with low specificity (54.4%), moderate sensitivity (86.7%) and high negative predictive value (94.5%) for detecting injury (ISS>15). Lactate measurements over 4.7 mmol/L were highly specific (95.8%) for injury.CONCLUSIONS:
Elevated admission venous lactate level is associated with injury and outcomes, but lacks adequate sensitivity and specificity. Lactate over 4.7 mmol/L is strongly suggestive of severe injury, while lactate below 2.0 mmol/L is reassuring for not having injury. Lactates between 2.0 and 4.7 mmol/L remain indeterminate in predictive potential for injury or outcomes.Palavras-chave
