Abstract:
Objective To investigate the application value of early lactate clearance rate and acute physiology and chronic health evaluation (APACHE) Ⅱ score in patients with acute carbon monoxide poisoning encephalopathy.Methods One hundred and forty-six patients with acute severe carbon monoxide poisoning were divided into control group (60 cases) and case group (86 cases) according to the occurrence of toxic encephalopathy.All the patients were extracting 1 ml arterial blood under the condition of air before treatment and 6,24,72 h after treatment,arterial blood lactic acid level was detected,and the lactate clearance rate was calculated.The initial level of blood lactic acid,lactic acid clearance rate and APACHE Ⅱ score 6,24,72 h after treatment,complication rate and mortality rate were compared between the two groups.Results Compared with control group,the initial level of blood lactic acid in case group was higher [(3.30 ± 0.55) mmol/L vs.(2.64 ± 0.24) mmol/L],the lactate clearance rate 6,24 h after treatment was lower [(8.22 ± 1.20)％ vs.(12.83 ± 5.31)％,(12.00 ± 2.40)％ vs.(15.17 ± 2.99)％],the APACHE Ⅱ score 6,24,72 h after treatment was higher [(16.78 ±2.82) scores vs.(12.33 ±2.16) scores,(14.11 ± 1.54) scores vs.(10.17 ±0.98) scores,(10.56 ± 1.51) scores vs.(7.83 ± 1.17) scores],the complication rate and mortality rate were higher,and there were statistical differences (P ＜ 0.05).There was no statistical difference in lactate clearance rate 72 h after treatment between the two groups (P ＞ 0.05).In acute carbon monoxide poisoning encephalopathy patients,the lactate clearance rate 6 h after treatment was negatively correlated with APACHE Ⅱ score and mortality rate (r =-0.616,P =0.015;r =-0.606,P =0.017).Conclusion Early lactate clearance rate and APACHE Ⅱ score can help to assessment the severity,guide treatment and judging prognosis in patients with acute carbon monoxide poisoning encephalopathy.
