Application of bedside continuous blood purification in patients with multiple organ dysfunction syndromes

BACKGROUND:The complications of systemic inflammatory response syndrome(SIRS)include acute lung injury,acute kidney injury,shock,and multiple organ dysfunction syndrome(MODS).In recent years,how to clear inflammatory mediators has become a hot topic in critical care medicine.Researchers hypothesize that continuous blood purification(CBP) can effectively eliminate a variety of inflammatory mediators which participate in the occurrence of MODS and adjust the immune imbalance.This study aimed to observe the effects of CBP in MODS patients.METHODS:In this retrospective clinical study,a total of 38 MODS patients,18 males and 20 females,were enrolled.After conventional therapy,all the patients received CBP.Biochemistry,blood gas analysis,oxygenation index,mean arterial blood pressure(MAP),acute physiology and chronic health evaluation(APACHE) II scores were monitored.RESULTS:After CBP,the vital signs of patients were rapidly stable,and electrolyte disorders and acid-base imbalance were corrected.Renal function,blood gas,oxygenation index were all improved.MAP was increased,and APACHE II score was significantly decreased.All patients had good tolerance,stable hemodynamics,and no obvious adverse reaction on CBP compared with pre-CBP.CONCLUSION:CBP can effectively clean toxins,correct electrolyte acid-base balance,and improve systemic inflammatory response syndrome and the organ function of MODS patients.

Sequential blood purification therapy for critical patients with hyperlipidemic severe acute pancreatitis

AIM: To evaluate the efficacy of sequential blood purification therapy in the treatment of critical patients with hyperlipidemic severe acute pancreatitis.METHODS: Thirty-one intensive care unit(ICU) patients with hyperlipidemic severe acute pancreatitis treated at the Second Affiliated Hospital of Harbin Medical University were divided into either a study group(n = 15; July 1, 2012 to June 30, 2014) or a control group(n = 16; July 1, 2010 to June 30, 2012) based on the implementation of sequential blood purification therapy. The control group received continuous venous-venous hemofiltration(CVVH) on the basis of conventional treatments, and the therapeutic dose of CVVH was 30 m L/kg per hour. The study group received sequential plasma exchange and CVVH on the basis of conventional treatments. The anticoagulation regimen of CVVH is the regional citrate anticoagulation. Mortality rate on day 28, rates of systemic and local complications, duration of ICU, and time to target serum lipid level, as well as physiologic and laboratory indices were compared between the two groups.RESULTS: The mortality rate on day 28 was significantly lower in the study group than in the control group(13.33% vs 37.50%; P < 0.05). The duration of ICU stay was significantly shorter in the study group than in the control group(7.4 ± 1.35 d vs 9.19 ± 2.99 d, P < 0.05). The time to target serum lipid level was significantly shorter in the study group than in the control group(3.47 ± 0.52 d vs 7.90 ± 1.14 d, P < 0.01). There were no significant differences in the rates of systemic complications and local complications between the two groups(60% vs 50% and 80% vs 81%, respectively). In the comparisons of physiologic and laboratory indices, serum albumin and C-reactive protein were significantly better in the study group than in the control group after treatment(37.8 ± 4.6 g/L vs 38.9 ± 5.7 g/L, and 20.5 ± 6.4 mg/L vs 28.5 ± 7.1 mg/L, respectively, both P < 0.05). With the exception of plateletcrit, no other indices showed significant differences between the two groups.CONCLUSION: Sequential blood purification therapy is effective in the treatment of ICU patients with hyperlipidemic severe acute pancreatitis and can improve patient prognosis.
