ABSTRACT
Objective The level of lactic acid in blood can reflect the degree of ischemia and hypoxia of brain tissue and cerebral perfusion pressure. The aim of this paper is to explore the value of blood lactate and lactate clearance in evaluating the survival rate and neurological outcome of patients with craniocerebral trauma. Methods The clinical data of 497 craniocerebral trauma patients admitted to our hospital from September 2017 to July 2018 were collected and retrospectively analyzed. Patients were divided into groups with different 6 h lactate clearance rates and admission lactate levels, and the differences in mortality and outcome of neurological function in each group were compared. Results The serum admission lactate levels、serum lactate levels at 6 hours, 28-day mortality and 28-day poor nerve function prognosis rate of patients with different 6h lactate clearance rates were statistically significant differences(P < 0. 05). The efficacy of 6h lactic acid to predict the mortality rate of patients was better than that of admission lactic acid and 6h lactate clearance rate (Z=3.71、Z=3.95,P<0.05). However, in predicting the neurological function of patients, the lactate clearance rate is not better than blood lactate level at any time(Z=1.30,Z=0.81,P>0.05). Conclusion 6h lactic acid has the best ability to judge the mortality of patients while lactic acid clearance rate is not better than the blood lactate level at any time in predicting the neurological function of patients.
