乳酸和急性生理学及慢性健康状况评分对老年脓毒症患者预后的评估

目的 研究乳酸和急性生理学及慢性健康状况评分(APACHEⅡ评分)对老年脓毒症患者预后的评估作用.方法 收集我院急诊科老年脓毒症患者90例,按照入院时血乳酸值分成乳酸升高组56例,乳酸正常组34例,比较2组的病死率、休克发生率、机械通气率和多器官功能障碍综合征(MODS)发生率和APACHEⅡ评分;根据APACHEⅡ评分(＜15、15～24、≥25)分为3组,比较3组患者的病情和预后.结果 乳酸升高组患者机械通气率、休克发生率、MODS发生率和病死率均明显高于乳酸正常组(33.9%比5.8%,35.7%比5.8%,42.8%比8.8%,30.3%比2.9%,均P＜0.01)、APACHEⅡ评分明显大于乳酸正常组(24.3±7.5)分比(16.1±5.2)分,P＜0.05],随着APACHEⅡ评分增高,患者病情逐渐加重,休克发生率和住院病死率明显升高(P＜0.05),患者乳酸水平也明显增高,分别是(1.7±0.5)、(3.9±0.6)、(6.2±1.3)mmol/L,P＜0.05].结论 血乳酸和APACHEⅡ评分都可以评估老年脓毒症患者病情严重程度和预后,两者升高提示预后较差.

Abstract：

Objective To study the prognosis function of lactic acid and acute and chronic physiology health scoreⅡ(APACHEⅡscore) in elderly patients with sepsis. Methods The Clinical data of 90 elderly patients with sepsis were collected at Department of Emergency, Xuanwu Hospital of Capital University of Medical Sciences. Patients with elevated blood lactic acid and 34 cases with normal lactic acid, the differences of fatality rate,shock, mechanical ventilation and MODS incidence and APACHE Ⅱ score were compared between 2 groups. According to APACHE Ⅱ score (＜15 scores, 15 -24 scores, ≥25 scores), the patients were divided into three groups,the difference of condition and prognosis were compared among each groups. Results The mechanical ventilation,shock, MODS and APACHE Ⅱ score in elderly septic patients with elevated lactate were significantly higher than those in normal lactic acid group( P ＜ 0.05) with mortality significantly increased(30.3% vs 2.9%, P =0.005).With the APACHE Ⅱ score increasing, the patient's illness was gradually worsened; shock incidence and hospital mortality were increased significantly, P ＜ 0.05. Conclusions The lactic acid levels and APACHE Ⅱ score can effectively assess the patients condition and prognosis, the elderly sepsis patients with elevated blood lactate had a serious condition and poor prognosis.
