  • Effect of Pulsed Colloid Infusion Combined with Continuous Blood Purification for Treatment of Severe Capillary Leak Syndrome

    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.
