Abstract:
Objective After acute craniocerebral trauma , to a certain extent , arterial blood lactate and lactate clearance rate reflect the illness severity .We aimed to investigate the prognosis value of arterial blood lactate and lactate clearance rate in patients with craniocerebral trauma . Methods 94 cases with craniocerebral trauma treated in the Department of Emergency of Nanjing General Hospital of Nanjing Military Regionfrom February 2015 to November 2015 were retrospecively analysed .GCS ( Glasgow Coma Scale ) score, arterial blood lactate , blood pressureand heart rate were measured once patients admitted to hospital and 6 hours later ,arterial blood lactate was measured again to calculated the arterial blood lac-tate clearance rate .Based on the GCS score , we divided the patients into mild group (13-15), medium group (9-12) and severe group (3-8).We also divided the patients into death group and survival group according toprognosis .We compared arterial blood lactate and lactate clearance rate betweeeneach group respectively . Results There were significant differences in arterial blood lactate (F=19.99,P<0.01) and 6h lactate clearance rate(F=6.21,P<0.01)be-tween lighter group , medium group and severe group .The initial arterial blood lactate of death group was significantly higher than sur-vival group[(4.20 ±1.36)mmol/L vs (1.58 ±0.93)mmol/L], the difference was statistically significant (t=-9.78,P<0.01). The 6 h lactate clearance rate of death group was significantly lower than survival group [(31.73 ±12.84)%vs (46.25 ±12.01)%], the difference was statistically significant (t=4.55,P<0.01). Conclusion Arterial blood lactate and 6 h lactate clearance rate can evaluate the severity and prognosisof illnessin patients with craniocerebral traumaand have important application value in clinical work .
