中文摘要:

目的：探讨高/低目标血压对老年脓毒症休克患者发生急性肾损伤（AKI）的影响。方法：选取2017年1月-2019年6月广西壮族自治区人民医院急诊重症监护病房（EICU）住院的老年脓毒症休克患者91例，随机分成高目标血压组(A组48例)和低目标血压组(B组43例)，目标平均动脉压(MAP)分别控制为80~85mmHg和65~70mmHg均给予5d脓毒症休克集束治疗。收集患者基线资料，使用床旁超声检测患者肾阻力指数（RI），尿气分析检测患者尿氧分压。比较2组治疗前、后急性生理与慢性健康状况评估（APACHEⅡ）评分、多器官功能障碍综合征（MODS）评分、RI、肾血流评分、尿氧压、肌酐、尿素氮等情况，Logistics回归分析AKI危险因素。结果：治疗后，与B组比较，A组患者APACHEⅡ评分、MODS评分、血乳酸水平、RI低于B组，而肾血流分级评分高于B组(P均<0.05)；Logistics回归分析提示MAP是老年脓毒症休克患者发生AKI的独立危险因素。结论：脓毒症休克集束治疗中高目标血压有助于改善老年患者肾灌注，降低AKI发生风险。

英文摘要:

Objective:To investigate the effect of high/low target blood pressure on acute kidney injury (AKI) in elderly patients with septic shock. Methods: Totally, 91 elderly patients with septic shock who were hospitalized in the Emergency Intensive Care Unit (EICU) of the People's Hospital of Guangxi Zhuang Autonomous Region from January 2017 to June 2019 were selected and randomly divided into two groups: high target blood pressure group (group A,n=48) and low target blood pressure group (group B，n=43), the target mean arterial pressure (MAP) was controlled to 80-85mmHg and 65-70mmHg respectively, and they were all given 5 days of septic shock cluster treatment. Baseline data of the patients were collected, renal resistance index (RI) of the patients was detected by bedside ultrasound, and urine oxygen partial pressure of patients was detected by urinalysis. The acute physiology and chronic health evaluation (APACHEⅡ) score, multiple organ dysfunction syndrome (MODS) score, RI, renal blood flow score, urinary oxygen pressure, creatinine, and blood urea nitrogen and other conditions were compared between the two groups before and after treatment. Logistics regression analysis was used to analyze the risk factors for AKI. Results: After treatment, as compared with group B, the APACHEⅡ score, MODS score, serum lactic acid level and RI in group A were significantly reduced, and the renal blood flow grading score was significantly increased (all P<0.05). Logistic regression analysis suggested that MAP was an independent risk factor for AKI in elderly patients with septic shock. Conclusion:High target blood pressure in septic shock cluster therapy can help improve renal perfusion in elderly patients and reduce the risk of AKI.
