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.
