连续性血液净化在治疗重症脓毒血症中的应用
【摘要】目的:探讨连续性血液净化(cbp)治疗重症脓毒血症患者的疗效。方法:对30例重症脓毒血症患者,在cbp治疗前、治疗期间及治疗结束后分别监测患者血流动力学参数、呼吸机参数及急性生理和慢性健康状况评分(apache ⅱ),测定动脉血气、肾功能、电解质,记录多巴胺用量及呼吸机参数。结果:所有治疗均进行顺利,经过cbp治疗,患者血流动力学较治疗前改善;氧合指数(pao2/fio2)、动脉氧分压(pao2)均升高、吸入氧浓度(fio2)下调,与治疗前比较差异有统计学意义(p<0.05);平均动脉压(mbp)升高,多巴胺的需要量明显减少(p<0.05);apache ⅱ评分、肌酐、尿素氮、血钾水平较治疗前明显降低(p<0.05)。结论:cbp能改善重症脓毒血症患者的血流动力学状况及肺氧合功能,维持内环境稳定,是一种可行、有益的辅助治疗重症脓毒血症的方法。

【abstract】 objective:to discuss the effect of continuous blood purification ( cbp ) in treatment of patients with severe sepsis patients.methods: 30 patients with severe
sepsis patients, in the cbp before treatment, during treatment and after treatment respectively monitor the hemodynamics of patients with ventilator parameters, and acute physiology and chronic health evaluation ( apache ii ),arterial blood gas measurements, renal function,electrolyte, recording of dopamine content and ventilator parameters.results:all treatments were performed smoothly,after cbp treatment than before treatment, patients with hemodynamic improvement; oxygenation index (pao2/fio2 ),arterial partial pressure of oxygen (pao2)were increased,inspired oxygen concentration ( fio2 ) down, and before treatment has significant difference (p<0.05); mean arterial pressure ( mbp elevated dopamine ), the need quantity decreased obviously (p<0.05);apache ii score, creatinine,blood urea nitrogen, serum potassium levels significantly decreased compared with those before treatment
( p<0.05 ).conclusion:cbp can improve in patients with severe sepsis hemodynamics and oxygenation function, to maintain a stable environment within, is a practical, useful adjunctive therapy in severe sepsis method.

脓毒血症(sepsis)是指感染和创伤等引起微生物侵入人体诱发
剧烈的全身炎性反应,并引起组织器官继发性损伤的病理生理过程及临床症候群,是临床上一种常见但较难治疗的综合征。有资料显示,美国每年有70万人患脓毒血症,其中死亡21万人,死亡率高达30%[1]。早期脓毒血症不经过及时有效治疗可进展为重症脓毒血症和脓毒血症性休克,两者是脓毒血症患者最常见的死亡原因。重症脓毒血症及脓毒血症性休克的死亡率分别为20%~30%和
40%~70%[2-3]。随着医学研究的深入,脓毒血症的治疗取得了很大进展。近年来,持续性血液净化(continuous blood purification,cbp)在脓毒血症患者抢救中的应用得到了飞速发展,显著提高了抢救成功率。本研究对icu病房中重症脓毒血症患者行cbp治疗,观察其对血流动力学、氧合功能及生化指标等的影响,探讨cbp对重症脓毒血症患者的治疗作用,为cbp用于治疗重症脓毒血症提供参考依据。现报道如下。
