摘要
目的 探讨心外ICU患者急性生理学及慢性健康状况评分Ⅱ（APACHEⅡ）与血乳酸水平的相关性及对预后的评估价值.方法 选取沈阳军区总医院心外科ICU 2013年12月1日至2014年11月30日收治的患者2340例,检测血乳酸水平.所有患者在入ICU 24 h内进行APACHEⅡ评分,评分以各项指标最差值计算,并按APACHEⅡ评分分为＜15分、15～24分、25～34分、＞34分四组.根据患者预后分为存活组和死亡组.分析血乳酸水平与APACHEⅡ评分的关系.结果 APACHEⅡ评分＜15分组与15～24分组间血乳酸浓度无明显差异,15～24分组血乳酸浓度明显低于25～34分组,25 ～34分组血乳酸浓度明显低于＞34分组,死亡组患者血乳酸浓度明显高于存活组,差异有统计学意义（P＜0.05）.死亡组APACHEⅡ得分为（24.30±7.95）分,生存组得分（7.68±3.91）分,两组比较差异有统计学意义（P＜0.01）.APACHEⅡ评分与血乳酸浓度呈显著正相关（r=0.805,P＜0.01）.结论 心外ICU患者血乳酸水平与APACHEⅡ评分存在相关性,对判断病情及预后具有重要意义.
Objective To explore the relationship between acute physiology and chronic health evaluation Ⅱ （APACHE Ⅱ ） Score and blood lactic acid level and the predicting value oftbe prognosis of patients admitted to Cardiac Surgery Intensive Care Unit. Methods From December 2013 to December 2014, 2340 patients were ana- lyzed in department of cardiovascular surgery, general hospital of Shenyang military region. The blood lactic acid levels were measured. All patients were scored by the worst index level in the APACHE Ⅱ score system within 24 hour after admission. The patients were divided into 4 groups： 〈15 score, 15-24 score, 25-34 score, 〉34 score according to APACHE II scores. All the patients were divided into two groups based on their prognosis： survival group and death group. The relationship between APACHE Ⅱ score and blood lactic acid level was analyzed. Re- stilts There was no significant difference in the blood lactic acid level between group 〈15 score and group 15-24 score. The blood lactic acid level in the group 15-24 score was significantly lower than group 25-34 score. The blood lactic acid level in the group 25-34 score was significantly lower than group 〉34 score（P〈0.05）. The blood lactic acid level in the survival group was significantly lower than the dead group （P〈0.05）. The APACHE Ⅱ score in the dead group was （24.30±7.95）scores, which was significantly higher than （7.68±3.91）scores in the survival group （P〈O.01）. The level of blood lactic acid was positively related to APACHE Ⅱ score （r=0.805,P〈0.01）. Conclusion The level of blood lactic acid was positively related to APACHE Ⅱ score, can be used to evaluate the severity and prognosis of patients of cardiac surgery ICU.
