[摘要] 目的 探討感染性休克患者的血乳酸清除率以及APACHEⅡ分值的相關性。 方法 選取2009年1月~2013年5月廣東省東莞市寮步醫院感染性休克患者70例為研究對象,所有患者均行血乳酸水平檢測及APACHEⅡ評分,并根據APACHEⅡ分值分為A組(< 20分)、B組(20~< 30分)、C組(≥ 30分);對比分析三組血乳酸水平與APACHEⅡ分值,分別統計治療后死亡(死亡組)與存活患者(存活組)的血乳酸水平、APACHEⅡ分值及血乳酸清除率,同時,對早期血乳酸清除率及APACHEⅡ分值作相關性分析。 結果 A組患者血乳酸水平與APACHEⅡ分值[(5.3±2.6)mmol/L、(12.7±4.8)分]明顯低于B組[(9.6±4.3)mmol/L、(33.8±7.4)分]、C組[(14.2±6.2)mmol/L、(62.3±10.8)分],差異有統計學意義(P < 0.05);C組血乳酸水平與APACHEⅡ分值明顯高于A、B兩組,差異有統計學意義(P < 0.05);死亡組血乳酸水平及APACHEⅡ分值[(13.7±6.4)mmol/L、(53.8±12.6)分]均明顯高于存活組[(7.3±4.2)mmol/L、(28.7±8.4)分],差異有統計學意義(P < 0.05);死亡組血乳酸清除率[(3.7±2.4)%]明顯低于存活組[(14.2±5.3)%],差異有統計學意義(P < 0.05);血乳酸清除率及APACHEⅡ分值呈負相關(r = -0.732,P < 0.05)。 結論 通過檢測血乳酸,計算早期血乳酸清除率,結合APACHEⅡ分值情況,進而對感染性休克的病情程度作出較準確判斷,以改善臨床救治效果。

[Abstract] Objective To investigate the correlation between blood lactate clearance rate and APACHE Ⅱ score of patients with septic shock. Methods 70 patients with septic shock from January 2009 to May 2013 in Liaobu Hospital of Dongguan City in Guangdong Province were selected as study objects, blood lactate levels of all patients were detected and scored by APACHE Ⅱ, and they were divided into group A (< 20 points), group B (20- <30 points), group C (≥ 30 points) according to APACHE Ⅱ scores; the blood lactate levels and APACHE Ⅱ score of three groups were compared and analyzed, and the blood lactate levels, APACHE Ⅱ scores and blood lactate clearance rate of the death (death group) and survival patients (survival group) after treatment were statistics analyzed. At the same time, the correlation between early blood lactate clearance rate and APACHE Ⅱ score was analyzed. Results The blood lactate levels and APACHE Ⅱ scores of patients in group A [(5.3±2.6) mmol/L, (12.7±4.8) points] were lower than those of group B [(9.6±4.3) mmol/L, (33.8±7.4) points] and group C [(14.2±6.2) mmol/L, (62.3±10.8) points], the differences were statistically significant (P < 0.05), the blood lactate levels and APACHE Ⅱ scores of patients in group C were higher than those of group A and group B, the differences were statistically significant (P < 0.05). The blood lactate levels and APACHE Ⅱ score in death group [(13.7±6.4) mmol/L, (53.8±12.6) points] were higher than those of the survival group [(7.3±4.2) mmol/L, (28.7±8.4) points], the differences were statistically significant (P < 0.05); the blood lactate clearance rate of death group [(3.7±2.4)%] was lower than that of the survival group [(14.2±5.3)%], the difference was statistically significant (P < 0.05). There was negative correlation between the blood lactate clearance rate and APACHE Ⅱ score (r = -0.732, P < 0.05). Conclusion The judgment of the severity of septic shock can make more accurate through detecting blood lactate, blood lactate clearance rate of early computing, and combined with APACHE Ⅱ score, in order to improve the clinical treatment effects.

感染性休克是常見的一種危急重癥,臨床病死率高,且在近些年發病率出現增加趨勢,威脅更多患者的健康和生命安全。臨床采用早期液體復蘇、機械通氣以及有效控制感染等治療后,取得了較明顯的效果,但病死率仍比較高。采用合理的評價方式,及早對患者的病情作出準確的評估,并對危險程度較高的患者盡早采取干預和控制措施,有利于病死率的降低[1]。急性生理學及慢性健康情況評分(APACHEⅡ評分)可對感染性休克患者的病情程度進行較為合理的判斷,一般APACHEⅡ評分值愈高,患者的病情愈重[2]。臨床初步認為,APACHEⅡ分值與血乳酸清除率存在一定相關性,本研究對血乳酸清除率及其與APACHEⅡ分值的相關性進行探析。具體研究結果報道如下:
