Objective To investigate the efficacy of continuous blood purification ( CBP) in the treatment of severe sepsis, and explore the related immune regulatory mechanisms. Methods Forty-eight patients with severe sepsis were randomly divided into a control group ( n =23) and a CBP group ( n =25) .CD4 + CD25 + regulatory T cells ( Treg% ) in peripheral blood and APACHEⅡ score were measured dynamically before treatment and 12, 24, 36, 48, 60, 72 hours after treatment. Meanwhile the length of ICUstay, duration of mechanical ventilation, and 28 day mortality were determined. Results Compared with the control group, the length of ICU stay, ventilator time, incidence of multiple organ failure, and mortality decreased significantly in the CBP group ( P lt; 0. 05) . And CBP also decreased Treg% and APACHEⅡ score significantly. There was a positive correlation between Treg% and APACHEⅡ score ( r =0. 804, P lt;0. 01) .Conclusion Early CBP treatment can reduce Treg%, improve cellular immunity and improve the prognosis of sepsis.
Objective To investigate the value of continuous blood purification （CBP）in early treatment of patients with ARDSexp （ARDS caused by extrapulmonary causes），especially in reducing inflammation mediators and extravascular lung water （EVLW）.Methods According the hospital admission sequence，the patients with APACHEⅡ scores from 15 to 20 and PaO2/FiO2 from 100 to 200 were recruited.The ARDSexp patients were divide into an intervention group treated with CBP （Mode：CVVHDF，rate of displacement liquid and dialysate：1.5 L/h，rate of blood：100-200 mL/h，and the time of CBP：72 hours），and a control group without CBP treatment. The NICO and PICCO monitoring data and the survival rates were recorded and analyzed using the SPSS software. Results The mortality rate of the intervention group was lower than that of the control group （6.3% vs. 36.8%，P=0.032）. In the 72 h monitoring dada of NICO and PICCO，the time of improving PCBF，Pm，Cdyn，VCO2，MValv，Pm，PIP，Raw，RSBI，Vd/Vt，and PaO2/FiO2 of the intervention group was severer than those in the control group，and the severety was also more than that of control group which was was significantly different at 72 h（Plt;0.05）. In the PICCO data，the time of decreasing EVWL and PVPI was shorter than the control group，and the decreasing extent was more than the control group，with significant difference at 72 h. But the changes of Apm，CI，and CVP were not significant （Pgt;0.05）. Conclusions In treatment of ARDSexp patients，CBP therapy can induce the PCBC and EVLW，improve pulmonary compliance and MValv，and reduce the mortality rate，while doesn’t influence heart function and the stability of circulation.
During the medical rescue after Wenchuan earthquake, based on the design and implementation of the management process of blood purification equipment, we gave the top priority to those patients with post-disaster crush syndrome to ensure their hemodialytic treatment. Through strict management of blood purification technology, the outcomes of these patients have been fundamentally improved and the incidence of complications was substantially reduced. Safe and effective hemodialytic treatment have been administered to 77 patients with crush syndrome (813 case-times).
In this article, the first time use of continuous veno-venous hemofiltration(CVVH) combined with toxic absorption for the treatment of a crush syndrome patient injured in earthquake is described. Correct therapeutic regimen, close observation and prescription condition are crucial for the success of management. The evidence for the application of this method is also discussed in detail.
目的:提高群蜂蛰伤致急性肾衰竭(ARF)的诊断和治疗水平。方法:回顾性分析我科7年来收治的23例群蜂蛰伤致ARF的临床资料,初步探讨其疗效及死因等。结果:23例群蜂蛰伤致急性肾功能衰竭患者,少尿型ARF为20例(占87%)无尿型ARF为3例(占13%);均伴有心肌酶、肌酸激酶、乳酸脱氢酶、谷丙转氨酶(ALT)升高;主要并发症为中毒性心肌炎(23/23,1000%)、横纹肌溶解肌症(23/23,1000%)、血红蛋白尿(21/23,913%)、血管内溶血(21/23,913%)、中毒性肝炎(16/23,696%)等;入院后12h内,10例行血液透析(hemodialysis,HD),13例行血液灌流(hemoperfusion,HP)/透析联合治疗(HP/HD);两组患者总治愈好转率为870%,病死率为130%;其中HD组治愈好转率为700%(7/10),病死率为30%(3/10),HP/HD组治愈好转率为100%(13/13),病死率为0,两组间疗效存在显著差异(P=0034);但所观察的病例中,HD组为我科前3年治疗蜂毒致ARF的方案,HP/HD组为我科后4年主要治疗蜂毒致ARF的方案,组间存在时间差异,并且病例数亦较少,因此两组的疗效对比有待进一步研究。3例患者死亡原因为多系统脏器功能衰竭(MSOF)。结论:蜂毒中毒所致急性肾功能衰竭以少尿型为主,同时伴有心、肝、血液、神经系统等重要组织器官的损伤,病情重;患者主要死亡原因为全身多系统器官功能衰竭(MSOF);尽早行血液净化是治疗群蜂蛰伤有效手段,其中条件允许的医院建议首选HP/HD联合治疗。
ObjectiveTo investigate the effect of pulsed colloid infusion combined with continuous blood purification (CBP) for treatment of severe capillary leak syndrome (CLS). MethodsAccording to random principle,61 patients were divided into a control group(n=21),a CBP1 group(n=18) and a CBP2 group(n=22). All patients of three groups received routine treatment according to international guidelines 2008 for management of severe sepsis. The patients in the control group also received pulsed infusion colloid combined lasix. The patients in the CBP1 and CBP2 groups also received continuous veno-venous hemofiltration(CVVH) for 72 hours. The patients in the CBP1 group received concentrated colloid infusion combined lasix,and the patients in the CBP2 group received concentrated colloid infusion combined removing fluid. Blood gas analysis and Impedance Cardiography was performed before and 24,48 and 72 hours after therapy. The angiopoietin-2(Ang-2) was measured. Also the length of ICU stay,duration of mechanical ventilation,and death rate of patients in 28 days were observed. ResultsCompared with the control group and the CBP1 group,the length of ICU stay(days) and duration of mechanical ventilation (days) in the CBP2 group were significantly shorter(P<0.05),and the death rate in 28 days was lower(P<0.05). The patients in the CBP2 group showed more reduction in the APACHEⅡ score compared with the CBP1 group after therapy(P<0.05). The oxygenation index in the CBP2 group respectively increased at 24,48 and 72 hours after therapy(P<0.05). Compared with the control group and the CBP1 group,the oxygenation index in the CBP2 group respectively increased at the same time(P<0.05). The thoracic fluid content (TFC) in the CBP2 group respectively decreased at 24,48 and 72 hours(P<0.05) after therapy,and decreased compared with the control group and the CBP1 group at the same time(P<0.05). The serum levels of Ang-2 in the CBP2 group respectively decreased at 24,48 and 72 hours after therapy(P<0.05),and decreased compared with the control group and the CBP1 group at the same time(P<0.05). ConclusionPulsed colloid infusion combined with continuous blood purification can reduce the severity of capillary leak and improves the outcome of patients with severe sepsis.
ObjectiveTo investigate the therapeutic effect of B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site in treatment of hyperlipidemic severe acute pancreatitis (HL-SAP). MethodsThe clinical data of 34 patients with HL-SAP initially underwent B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site from January 2010 to June 2014 were retrospectively analyzed. According to the different of the onset to treatment time, 34 cases were divided into the≤24 h group and > 24 h group. The serum platelet activating factor (PAF) and triglyceride (TG) at the time of admission and after admission 1, 3, 5, 7, and 10 days were detected, and the hospitalization time, mortality, and the rate of conversion to open surgery were observed. ResultsThe levels of PAF and TG in the both groups tended to gradually decrease with different degrees, were significantly lower than that the before treatment (P < 0.05), and the decline of PAF and TG in≤24 h group were more significant than > 24 h group. The hospitalization time, mortality, and the rate of conversion to open surgery in the≤24 h group were significantly lower than those of the > 24 h group (P < 0.05). ConclusionThe early using of B ultrasound-guided percutaneous catheter drainage combined with veno-venous hemofiltration at different time points and multi-site would have a beneficial impact on the management of HL-SAP and complications.
Objective To observe the prognosis of pregnant patients with renal failure who underwent blood purification. Methods Pregnant patients with renal failure undergoing blood purification (hemodialysis or hemofiltration) from January 2009 to February 2017 were included in this study. Clinical data and pregnancy outcome were collected retrospectively. Results A total of 42 patients were enrolled in this study, including 38 with acute renal failure, 3 with chronic progressed renal failure, and 1 with chronic renal failure. There were 5 patients (11.9%) with chronic kidney disease (CKD) before pregnancy, 3 (7.2%) with systemic lupus erythematosus, 24 (54.8%) with hypertension, 5 (11.9%) with acute pancreatitis, and 7 (14.3%) with acute liver failure. In perinatal period, 7 patients (16.7%) died, whose underlying diseases were acute pancreatitis in 2, lupus nephritis in 1, acute hepatic failure in 3, and pulmonary tuberculosis breakout in 1. There were 5 patients with twin pregnancy, and 37 patients with single pregnancy. In the 28 patients with natural pregnancy ending, the live birth rate was 82.1% (23/28), and the live birth rate of twin pregnancy was only 50% (5/10). Twenty-seven patients were followed up, in whom 10 were in end stage of renal disease (ESRD), which was correlated with hypertension (P=0.001), and 3 patients were in CKD 1–4. Renal diseases were completely recovered in 14 patients. New CKD were diagnosed in 8 patients, without any correlated factor. Conclusions For pregnant patients with renal failure undergoing hemodialysis or hemofiltration, the death risk and the dead birth rate are high. Patients with hypertension or pre-existed renal failure have higher risk for ESRD. Some patients are not completely recovered from acute renal failure, with CKD left.
