Abstract
Objective To investigate the fast,simple,effective and practical indicator for evaluating the prognosis in the patients with traumatic hypovolemic shock. Methods 34 patients with traumatic hypovolemic shock in ICU of the Neijiang Mu-nicipal Second People′s Hospital from July to December 2012 were selected. The ISS ,APACHEⅡscores were determined when admitting in ICU and the arterial blood lactic acid value was monitored,re-detection was conducted at 6,12,24 h,the blood lac-tate clearance rate at 6,12,24 h was calculated. According to the outcomes of disease,the patients were divided into the survival group(28 cases) and the death group(6 cases). The blood lactic acid values at 0,6,12,24 h,lactic acid clearance rate at 6,12, 24 h,ISS score and APACHEⅡscore and their relation with prognosis were compared. Results The ISS score and APACHEⅡscore in the survival group were lower than those in the death group,the difference was statistically significant(P<0.05). The blood lactic acid level immediately admitting to ICU had no statistical difference between the two groups (P>0.05). The initial arterial blood lactic acid value in the survival group was lower than that in the death group ,but without statistical difference (P>0.05),the blood lactic acid level at 6, 12, 24 h after treatment showed the decreasing trend,while which in the death group was continuously increased,the difference was statistically significant(P<0.05). The lactic acid clearance rate at 6,12,24 h after treatment in the survival group was significantly higher than that in the death group ,the differences were statistically significant. Conclusion The 6 h lactic acid clearance rate can be used for the early evaluation of prognosis in the patients with traumatic hy-povolemic shock.关键词
