ABSTRACT
Objective:To investigate the effect of bedside high-flow continuous blood purification (CBP) combined with Xuebijing in the treatment of severe sepsis (SS) and the influence on the patient′s coagulation-fibrinolysis index, immunity index and expression of peripheral blood Toll-like receptor 4 (TLR4).Methods:Ninety-three patients with SS who were admitted and treated in the Lianyungang First People′s Hospitalfrom January 2017 to October 2019 were selected. They were divided into the combined group (51 cases, treatment with bedside high-flow CBP and Xuebijing injection based on bundle therapy) and the control group (42 cases, treatment with Xuebijing injection based on bundle therapy). The changes in coagulation and fibrinolysis index, immunity index, biochemical index such as TLR4 before treatment and after 1 week of treatment were compared between the two groups. The incidences of complications in both groups were statistically analyzed, and the discharge time from ICU, mechanical ventilation time and 28-day mortality were recorded.Results:After 1 week of treatment, the levels of prothrombin time (PT) and activated partial thromboplastin time (APTT) in the two groups were shortened, D-dimer (D-D) and fibrinogen (FIB) were decreased ( P<0.05); and the levels of PT and APTT in the combined group were shorter than those in the control group, the levels of DD and FIB were lower than those in the control group, there were statistical differences ( P<0.05). After 1 week of treatment, the levels of CD 4+ and CD 4+/CD 8+ ratio in both groups were increased ( P<0.05), and the levels of CD 4+ and CD 4+/CD 8+ ratio in the combined group were higher than those in the control group ( P<0.05). After 1 week of treatment, the levels of TLR4, C-reactive protein (CRP), procalcitonin (PCT), white blood cell count (WBC), blood lactate (Lac), blood urea nitrogen (BUN) and serum creatinine (Scr) in both groups were decreased ( P<0.05), meanwhile, the above indexes in the combined group were lower than those in the control group ( P<0.05). The incidence of multiple organ failure and the 28-day mortality rate in the combined group were lower than those in the control group: 3.92%(2/51) vs. 19.05%(8/42), 13.73%(7/51) vs. 30.95%(13/42), there were statistical differences ( P<0.05). The discharge time from ICU and mechanical ventilation time in the combined group were shorter than those in the control group: (12.35 ± 2.14) d vs. (14.17 ± 3.36) d, (7.12 ± 2.23) d vs. (8.51 ± 2.39) d, there were statistical differences ( P<0.05). Conclusions:Bedside high-flow CBP combined with Xuebijing injection in the treatment of SS can improve the patient′s condition, regulate the balance of coagulation and fibrinolysis, avoide the activation of coagulation, inhibite inflammatory response, reduce the expression of TLR4 in peripheral blood, improve immune function, protecte kidney function and promotethe patient′s recovery.
ABSTRACT
Severe acute pancreatitis (SAP) is a common gastrointestinal disease, often accompanied by systemic inflammatory reactions and organ dysfunction. SAP has an acute onset, severe condition, rapid progression, and poor prognosis. The development of SAP is closely related to the excessive release of inflammatory factors. In the comprehensive treatment of SAP, continuous blood purification (CBP) can clear inflammatory mediators, improve the stability of Internal environment, improve organ function, reduce blood lipids, regulate immunity, and significantly improve the condition of SAP patients. It is an important means of treating SAP. This article reviews the research progress of CBP in the treatment of SAP.
ABSTRACT
Objective:To compare the effects of citrate and heparin anticoagulation on coagulation function and efficacy in children with septic shock undergoing continuous blood purification (CBP), and to provide guidance for CBP anticoagulation in children with septic shock.Methods:A case control study was conducted. Thirty-seven children with septic shock admitted to the pediatric intensive care unit (PICU) of the First Affiliated Hospital of Gannan Medical University from July 2019 to September 2022 were enrolled as the research subjects. The patients were divided into citrate local anticoagulation group and heparin systemic anticoagulation group according to different anticoagulation methods. The baseline data, the level of coagulation indicators [prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), fibrinogen (Fib), D-dimer] before treatment and 1 day after weaning from CBP, serum inflammatory mediators [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α), hypersensitivity C-reactive protein (hs-CRP), procalcitonin (PCT)], bleeding complications during CBP and 7-day mortality were collected.Results:A total of 37 cases were enrolled finally, including 17 cases with citric acid local anticoagulation and 20 cases with heparin systemic anticoagulation. There was no statistically significant difference in general data such as gender, age, and body weight of children between the two groups. There were no statistically significant differences in baseline levels of coagulation indicators and inflammatory mediators before treatment of children between the two groups. One day after weaning from CBP, both groups showed varying degrees of improvement in coagulation indicators compared with those before treatment. Compared with before treatment, the PT of the heparin systemic anticoagulation group was significantly shortened after 1 day of weaning (s: 11.82±2.05 vs. 13.64±2.54), APTT and TT were significantly prolonged [APTT (s): 51.54±12.69 vs. 35.53±10.79, TT (s): 21.95±4.74 vs. 19.30±3.33], D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 4.94±3.94), with statistically significant differences (all P < 0.05). While in the citrate local anticoagulation group, only APTT was significantly prolonged after treatment compared with that before treatment (s: 49.28±10.32 vs. 34.34±10.32, P < 0.05). There were no statistically significant differences in other coagulation indicators compared with before treatment. Compared with the citric acid local anticoagulation group, the PT of the heparin systemic anticoagulation group was significantly shortened after treatment (s: 11.82±2.05 vs. 13.61±3.05, P < 0.05), and the D-dimer level was significantly reduced (mg/L: 1.92±1.58 vs. 3.77±2.38, P < 0.01). The levels of inflammatory mediators in both groups were significantly reduced 1 day after CBP weaning compared with those before treatment [citric acid local anticoagulation group: hs-CRP (mg/L) was 12.53±5.44 vs. 22.65±7.27, PCT (μg/L) was 1.86±1.20 vs. 3.30±2.34, IL-6 (ng/L) was 148.48±34.83 vs. 202.32±48.62, TNF-α (ng/L) was 21.38±7.71 vs. 55.14±15.07; heparin systemic anticoagulation group: hs-CRP (mg/L) was 11.82±4.93 vs. 21.62±8.35, PCT (μg/L) was 1.90±1.08 vs. 3.18±1.97, IL-6 (ng/L) was 143.81±33.41 vs. 194.02±46.89, TNF-α (ng/L) was 22.44±8.17 vs. 56.17±16.92, all P < 0.05]. However, there was no statistically significant difference between the two groups (all P > 0.05). There was no statistically significant difference in bleeding complication during CBP and 7-day mortality in children between the citrate local anticoagulation group and the heparin systemic anticoagulation group (5.9% vs. 30.0%, 17.6% vs. 20.0%, both P > 0.05). Conclusions:Heparin for systemic anticoagulation and regional citrate anticoagulation can significantly reduce the levels of IL-6, TNF-α, hs-CRP and PCT in children with septic shock, and relieve inflammatory storm. Compared with citric acid local anticoagulation, heparin systemic anticoagulation can shorten the PT and reduce the level of D-dimer in children with septic shock, which may benefit in the prevention and treatment of disseminated intravascular coagulation (DIC).

The control group was treated with intermittent hemodialysis (IHD), while the observation group was treated with CBP. Changes of the efficacy, the renal function indexes, cardiac function indexes, p66Shc protein, sFlt-1, TIMP-1 before and after treatment were compared between the two groups. The occurrence of adverse reactions were recorded.Results:The total effective rate in the observation group was better than thatin the control group: 79.59% (39/49) vs. 60.42% (29/48), χ 2 = 4.25, P<0.05. After treated for 1 week, the levels of blood urea nitrogen, serum creatinine, serum phosphorus, blood uric acid and β2 microglobulinin the observation group were lower than those in the control group: (12.63 ± 3.14) mmol/L vs. (16.23 ± 4.74) mmol/L, (175.52 ± 39.57) μmol/L vs. (240.15 ± 50.18) μmol/L, (1.20 ± 0.23) mmol/L vs. (1.37 ± 0.31) mmol/L, (265.15 ± 34.79) μmol/L vs.(297.52 ± 50.07) μmol/L, (28.75 ± 5.14) mg/L vs. (33.52 ± 7.39) mg/L, the differences were statistically significant ( P<0.05). The levels of left ventricular ejection fraction, cardiac output and stroke volume in the observation group were higher than those in the control group: (53.63 ± 7.96)% vs. (49.52 ± 5.14)%, (58.45 ± 15.23) ml vs. (49.58 ± 9.52) ml, (4.59 ± 0.52) L/min vs. (4.01 ± 0.23) L/min, the differences were statistically significant ( P<0.05). The levels of p66Shc, sFlt-1, TIMP-1 in the observation group were lower than thosein the control group: 1.11 ± 0.36 vs. 1.45 ± 0.42, (15.76 ± 4.34) μg/L vs. (19.87 ± 5.66) μg/L, (59.14 ± 10.57) μg/L vs. (65.39 ± 9.45) μg/L, the differences were statistically significant ( P<0.05). The total adverse reaction rate in the observation group was lower than that in the observation group: 14.29% (7/49) vs. 31.25% (15/48), χ2 = 3.98, P<0.05. Conclusions:CBP therapy for patients with severe heart failure combined with renal failure has better efficacy than IHD, and can improve the patient′s cardiac and kidney function, reduce the levels of p66Shc protein, sFlt-1 and TIMP-1, reduce adverse reactions. It is safe and feasible.
ABSTRACT
Continuous blood purification(CBP)has been extensively used in pediatric critical care and proven effective in pediatric patients with cerebral edema.However, as a causative factor of changes in blood pressure, blood volume, plasma osmotic pressure, and drug metabolism, CBP may have reduced efficacy and even exacerbate the cerebral edema when pediatric patients are provided with inadequate clinical evaluation and intervention or inappropriate settings of treatment parameters.This paper presented a literature review on the application strategies of CBP as a treatment of pediatric patients with cerebral edema to provide a reference for clinical practice.
ABSTRACT
Objective:To systematically evaluate the influencing factors on unplanned shutdown of continuous blood purification, and to provide reference basis for the prevention of unplanned shutdown.Methods:The literatures related to the influencing factors of unplanned shutdown of continuous blood purification in CNKI, Wanfang Database, Chinese Biomedical Literature Database, Chinese Science and Technology Periodical Full-text Database, PubMed and Web of Science were searched.The retrieval time of Chinese database was from the establishment of the database to March 2021.English databases were searched from March 2016 to March 2021.Literature selection, quality evaluation and data extraction were independently conducted by two researchers, and Meta-analysis was performed by Stata 14.0 software.Results:A total of 11 studies were included, including 3 031 cases of continuous blood purification treatment and 1 412 cases of unplanned discontinuation.The combined OR value and 95% CI of all influencing factors were as follows: treatment mode 2.22 (1.06-4.62), blood flow velocity 0.91 (0.776-1.09), agitation 4.54 (2.33-8.86), ventilator 2.67 (1.63-4.38), transfusing blood products and fat milk 1.07 (0.34-3.36), one-time catheter success 0.26 (0.05-1.42), catheterization site (femoral vein vs.jugular vein) 2.24 (0.83-6.02). Conclusion:Unplanned deplaning is influenced by many factors.Treatment mode, agitation and ventilator use are the risk factors for unplanned deplaning.There is no correlation between blood flow velocity, transfusing blood products and fat milk, one-time catheterization success, catheterization site and unplanned deplaning.
ABSTRACT
Objective:To discuss the role of continuous blood purification (CBP) therapy in children with severe adenovirus pneumonia.Methods:A total of 114 children with severe adenovirus pneumonia admitted to the Department of PICU at Children′s Hospital of Hunan Province from June 2018 to July 2019 were selected as the research objects.According to whether treated with CBP, they were divided into CBP group and control group.The following indicators during the process of treatment were compared between two groups, including respiratory mechanics indicators[respiratory index(PaO 2/FiO 2), dynamic lung compliance(Cdyn)]; hemodynamic indicators(heart rate and mean arterial pressure); changes in levels of inflammatory factors interleukin(IL)-6, IL-10, tumor necrosis factor(TNF)-α and the prognosis 28 days after admission. Results:The respiratory mechanics index, serum IL-6 and TNF-α levels of two groups after treatment were significantly lower than those before treatment, and the serum IL-10 level was significantly higher than that of this group before treatment.There were statistical differences in the CBP group before and after treatment, while there was no statistical difference in control group.In the CBP group, the serum IL-6 and TNF-α levels after treatment were significantly lower than those of the control group( P<0.05), and the serum IL-10 level was significantly higher than that of the control group( P<0.05). The 28-day mortality rate of patients in CBP group was 8.6%(3/35), which was significantly lower than 13.9%(11/79) of control group ( P<0.05). Conclusion:CBP could improve the main respiratory mechanical indexes of adenovirus pneumonia and decrease the level of inflammatory cytokines.
ABSTRACT
Objective:To investigate the effect of plasma exchange (PE) and continuous blood purification(CRRT) on children with bee sting poisoning and multiple organ dysfunction syndrome (MODS).Methods:From January 2016 to September 2019, 37 children aged 9 months to 11 years with bee sting and MODS were treated with dexamethasone 0.5 mg/kg or methylprednisolone 3 mg-5 mg/kg anti allergic and anti-inflammatory and organ support. Among them, 26 cases were treated with plasma exchange and continuous blood purification (treatment group), and the rest 11 cases were only given conventional treatment, but did not receive blood purification treatment (control group).The critical illness score, liver and kidney functions, myolysis, pulmonary hemorrhage/pulmonary edema, coagulation disorders, shock, hemolysis, gastrointestinal failure and other organ damage, ICU stay time, mechanical ventilation time, organ dysfunction recovery time and clinical outcomes were retrospectively analyzed. In the treatment group, 18 cases started blood purification before 12 h after MODS (early treatment group) and 8 cases started blood purification after 12 h (delayed treatment group).Results:There was no significant difference in age, sex, child critical illness score, onset time and organ function damage between the treatment and control groups ( P>0.05). The cure rate of the treatment group was higher than that of the control group [(25/26 (96.15%) vs 8/11 (72.73%), P=0.036]. There was no significant difference in ICU stay between the control group and the treatment group [(10.03±7.74) d vs (12.01±6.95) d, P>0.05]. Among the 25 survivors in the treatment group, one patient had mild renal function damage and one patient had multiple necrosis of skin, subcutaneous and muscle tissue. Compared with 4 of the 8 survivors in the control group, the residual organ function damage in the treatment group was significantly less than that in the control group [(2/25 (8.00%) vs 4/8 (50.00%), P=0.031)].The recovery of liver function, renal function, myolysis and hemolysis in the treatment group was faster than those in the control group (all P < 0.05). The initiation of blood purification within 12 h after the occurrence of MODS required fewer times of plasma exchange and shorter CRRT time, ICU stay and ventilator time (all P < 0.05). Conclusions:In children with bee sting combined with MODS, plasma exchange and continuous blood purification can achieve better therapeutic effect and better clinical outcome.
ABSTRACT
Objective@#To explore the method of the blood return of continuous blood purification therapy for patients with heart failure.@*Methods@#A total of 69 patients with heart failure treated by continuous blood purification therapy in our ICU from January 2017 to January 2018 were randomly divided into experimental group (blood return with blood bag,35 patients) and the control group (blood return with machine,34 patients). The vital signs, clinical manifestations and hemodynamic indicators of each patient were collected during the blood return of the first CBP therapy, and the data were analyzed between the two groups.@*Results@#After blood return of the first CBP therapy, the exacerbation of New York Heart Association (NYHA) heart function grade, SpO2, CVP, HR of patients in the control group were 33.27% (11/31), 0.91 ± 0.06, (12.44 ± 1.43) cmH2O (1cmH2O=0.098 kPa), (118.17 ± 3.27) times per minute and those in the experimental group were 6.25% (2/32), 0.96±0.04, (8.98±1.36) cmH2O, (90.45 ± 3.35)times per minute, respectively. The difference was statistically significant between the two groups (χ2=3.786, t=2.861, -7.565, 3.792, P< 0.05). Subgroup analysis showed that for patients within 24 hours of CBP treatment, the exacerbation of NYHA heart function grade, SpO2, CVP, HR of the control group and the experimental group were respectively 76.92% (10/13), 0.86±0.01, (12.92±1.12) cmH2O, (111.38±2.96) times per minute and 8.33% (1/12), 0.94±0.01, (8.11±0.74) cmH2O, (90.34±1.32) times per minute, the difference was statistically significant (χ2 =9.345, t=-14.101, 2.894, 7.648, P < 0.05). For patients treated with CBP therapy over 24 hours, the difference of the exacerbation of NYHA heart function grade, SpO2, CVP, HR of the control group and the experimental group was not statistically significant (P>0.05).@*Conclusions@#In patients with heart failure treated with CBP, especially in those treated with CBP therapy within 24 hours, blood return with blood bag may avoid the recurrence of heart failure.
ABSTRACT
Objective To study the clinical effects of continuous blood purification (CBP) in the treatment of newborns with severe sepsis and multiple organ dysfunction syndrome (MODS). Method From May 2013 to November 2018, the clinical data of infants with severe sepsis and MODS receiving CBP in the neonatal department of our hospital were retrospectively analysed. Changes of blood pressure, arterial partial pressure of oxygen/inhaled oxygen concentration (PaO2/FiO2), pH, serum potassium, sodium, urea nitrogen, creatinine, urine volume and maintenance dose of adrenaline at different time points before and after CBP were analysed. Result According to the inclusion and exclusion criteria, a total of 8 newborns with sepsis and MODS were enrolled in the study. One patient had the complication of perforated colon, and the other one had acute renal failure. The number of affected organs in these infants was 3～5. Six cases began CBP treatment within 1～5 days after admission, and the other two cases began CBP treatment on the 38th and 47th days after admission. The average treatment duration was (58.6±25.9) h. The effective rate of CBP in the treatment of severe sepsis with MODS was 75.0％(6/8). Blood pressure was increased at 6 h, 12 h, 24 h and 48 h after treatment and at the end of treatment. PaO2/FiO2 and blood pH were increased. The urine volume was increased at 24 h and 48 h after treatment and at the end of treatment (P<0.05). Serum potassium, urea nitrogen and creatinine were significantly decreased (P<0.05). The maintenance dose of adrenaline was also decreased significantly at 12 h after CBP (P<0.05), and withdrawn at 48 h after treatment. Only one case experienced membrane blockage during CBP. Dialysis was continued after the replacement of filtration membrane. No other complications existed. Conclusion CBP is effective in the treatment of neonatal severe sepsis with MODS. It can improve the circulation and renal function.
ABSTRACT
The aim of this study was to discuss the safety and efficacy of regional citrate anticoagulation (RCA) on continuous blood purification (CBP) during the treatment of multiple organ dysfunction syndrome (MODS). Thirty-five patients with MODS were divided into two groups: the local citrate anticoagulation (RCA) group, and the heparin-free blood purification (hfBP) group. The MODS severity was assessed according to Marshall's MODS score criteria. Blood coagulation indicators, blood pressure, filter lifespan, filter replacement frequency, anticoagulation indicators, and main metabolic and electrolyte indicators were analyzed and compared between RCA and hfBP groups. RCA resulted in lower blood pressure than hfBP. The filter efficacy in RCA treatment was longer than in the hfBP group. The blood clearance of creatine, blood urea nitrogen and uric acid was better in the RCA group. RCA also led to higher pH than hfBP. Neither treatment resulted in severe bleeding events. In addition, MODS score was positively correlated with prothrombin time and activated partial thromboplastin time but negatively correlated with platelet concentration. RCA is a safer and more effective method in CBP treatment; however, it could also lead to low blood pressure and blood alkalosis.

Objective@#To evaluate the effect of plasma exchange combined with high-dose continuous venovenous hemodiafiltration method (CVVHDF) in the treatment of patients with acute-on-chronic liver failure with stage III-IV hepatic encephalopathy and the feasibility of pre-operative preparation for liver transplantation.@*Methods@#Clinical data of 14 cases of medical intensive care unit of our hospital with acute-on- chronic liver failure accompanied with stage III-IV hepatic encephalopathy that underwent plasma exchange combined with high-dose CVVHDF from March 2015 to September 2017 were retrospectively summarized. The indexes of liver and kidney function, blood coagulation function, arterial blood PH, lactic acid and blood ammonia were monitored before and after treatment. Heart rate, blood pressure, APACHE II score, and consciousness recovery time were observed. Student’s t- test was used to compare the mean values between the two groups.@*Results@#Serum total bilirubin (t = 9.43, P < 0.01), serum creatinine (t = 3.40, P < 0.01), serum ammonia (t = 10.64, P < 0.01), prothrombin activity (t = 9.19, P < 0.01), serum lactate (t = 9.25, P < 0.01), heart rate (t = 4.47, P < 0.01), and mean arterial pressure (t = 4.41, P < 0.05) were significantly improved in 14 patients before and after treatment. In addition, respiratory rate (t = 6.01, P < 0.01) and APACHE II score (t = 7.19, P < 0.01) were significantly improved (P < 0.05). Eight patients with stage III hepatic encephalopathy were treated with intermittent plasma exchange combined with CVVHDF for 3 to 14 days, and six patients with stage IV were transformed to stage III to II. Liver transplantation was successfully performed on 14 patients with shortest time duration of 3days, and longest time duration of 1 month.@*Conclusion@#Plasma exchange combined with CVVHDF can significantly improve liver and kidney functions, reduce blood ammonia level and improve mental health in patients with hepatic failure accompanied with stage III-IV hepatic coma. In addition, it also effectively increases the average arterial pressure, maintain stability of vital signs, maintain fluids, electrolytes and acid-base balance, create a stable internal environment for liver transplantation before operation, and extend time for liver transplantation.
ABSTRACT
Objective@#To investigate the effects of application of citrate anticoagulation in bedside continuous blood purification (CBP) of severe burn patients with sepsis, so as to provide reference for choosing anticoagulants in CBP of these patients.@*Methods@#Thirty severe burn patients with sepsis, conforming to the study criteria, were admitted to our burn intensive care unit from January 2014 to July 2017. Patients were divided into heparin group and citrate group according to computer randomization method, with 15 cases in each group. Patients in two groups all received bedside CBP treatment. Patients in heparin group used local heparin anticoagulation, while patients in citrate group used local citrate anticoagulation. Time of predicted single-time CBP treatment, time of single-time CBP treatment, time of accumulative CBP treatment, and rate of reaching the standard of CBP treatment time were counted. Changes of prothrombin time (PT), activated partial thromboplastin time (APTT), international normalized ratio (INR), fibrinogen, serum procalcitonin, and C-reactive protein (CRP) of patients before and after treatment were monitored. Hemorrhage in wounds, incision on trachea, and arteriovenous intubation point, and other complications during and after CBP treatment were observed. Data were processed with independent sample t test and chi-square test.@*Results@#(1) Time of predicted single-time CBP treatment of patients in the two groups was equal. Time of single-time CBP treatment and time of accumulative CBP treatment of patients in citrate group were longer than those in heparin group. Rate of reaching the standard of CBP treatment time of patients in citrate group was significantly higher than that in heparin group (χ2=16.655, P<0.01). (2) There was no statistically significant difference in PT, APTT, INR, fibrinogen, serum procalcitonin, and CRP of patients in the two groups before CBP treatment (t=0.203, -1.006, 0.203, 0.039, -1.591, -0.824, P>0.05). PT and APTT of patients in citrate group after CBP treatment were (14.2±1.6) and (45±7) s, respectively, significantly shorter than (15.5±1.4) and (53±6) s in heparin group (t=2.395, 3.321, P<0.05 or P<0.01). INR of patients in citrate group after CBP treatment was 1.13±0.12, significantly lower than 1.24±0.12 in heparin group (t=2.395, P<0.05). Fibrinogen of patients in citrate group after CBP treatment was (3.5±0.6) g/L, significantly higher than (3.0±0.6) g/L in heparin group (t=-2.427, P<0.05). Serum procalcitonin and CRP of patients in citrate group after CBP treatment were significantly lower than those in heparin group (t=2.520, 2.710, P<0.05). Decreased degree of serum procalcitonin and CRP of patients in citrate group after CBP treatment were (1.8±0.6) ng/mL and (143±69) mg/L, respectively, significantly higher than (0.9±0.6) ng/mL and (95±50) mg/L in heparin group (t=-4.033, -2.170, P<0.05 or P<0.01). (3) During CBP treatment, patients in heparin group experienced 21 times of exacerbation of wound hemorrhage and 10 times of new hemorrhage, including 2 times of hemorrhage at incision on trachea and 8 times of hemorrhage at arteriovenous intubation point. No exacerbation of hemorrhage or new hemorrhage happened in patients of citrate group. After CBP treatment, no electrolyte disturbance happened in patients of heparin group, but 1 patient in citrate group experienced hypocalcemia.@*Conclusions@#Application of citrate anticoagulation in bedside CBP of severe burn patients with sepsis shows light impact on systematic coagulation status, and can effectively decrease inflammation reaction of burn sepsis with low rate of hemorrhage.

Methods The clinical data of 33 patients with moderate and severe HTGP who were treated by CVVH combined with HP were retrospectively analyzed from March 2012 to March 2017 in Wuhan general hospital of the people's liberation army. The differences of vital signs and the serum levels of triglyceride (TG), total cholesterol (TC), low density lipoprotein (LDL), high density lipoprotein (HDL), amylase (AMS), interleukin-6 (IL-6), blood calcium (Ca2+) and white blood cell count (WBC), haemoglobin (Hb), platelet count (PLT) before and 24 hours,72 hours and 1 week after therapy were compared, the changes of recovery time to target serum TG level, frequency of blood purification therapy, time for disease situation becoming stable, days staying in hospital and mortality were observed. Results The levels of LDL were not high in patients with HTGP, the levels of TG and TC were decreased significantly after using CVVH plus HP, and after treatment for 24 hours statistical differences appeared compared with those before treatment [TG (mmol/L):7.14±1.04 vs. 11.90±2.03, TC (mmol/L): 7.47±1.04 vs. 10.20±1.26], the decline persisting to 1 week after treatment;the drop rates of TG and TC were the largest after the first combined treatment, and the TG drop rate was more obvious than that of TC [(51.92±14.18)% vs. (30.09±10.01)%, P < 0.05], an average of (2.58±1.45) days and (2.38±0.98) times of combined blood purification could restore the TG to its safe level (TG < 5.65 mmol/L), the time of disease situation tending to be stable was (7.46±3.05) days and the time of staying in hospital was (20.00±2.12) days. Systemic inflammatory response syndrome (SIRS) related vital signs and inflammatory response indicators were also improved obviously after the combined therapy (all P < 0.05), after treatment for 72 hours, various vital signs and Ca2+reached to their normal reference ranges, after treatment for 24 hours IL-6 began to decline significantly compared with that before treatment (ng/L: 120.85±16.45 vs. 151.05±18.19), and AMS and WBC returned to their normal reference ranges after treatment for 1 week. Conclusion CVVH combined with HP can quickly and effectively eliminate TG in blood in patients with HTGP and in the mean time it may ameliorate and block the early progression of SIRS, resulting in good therapeutic effect on alleviating the disease development and improving its prognosis.
ABSTRACT
Objective: To explore curative effect of bedside continuous blood purification (CBP) for pregnancy complicating severe acute pancreatitis (SAP). Methods: 85 patients with pregnancy complicating SAP were divided into observation group (n=45) and control group (n=40). Patients of control group received series of symptomatic and supportive treatment included surgical termination of pregnancy, drainage, fasting, gastrointestinal decompression, fluid infusion, acid suppression, enzyme suppression and so on. And patients of control group were implemented the above treatments of control group combined with CBP at bedside. The acute physiology age and chronic health evaluation II (APACHE II) score, multiple organ dysfunction syndrome (MODS) score, the change of serum biochemical and inflammatory markers, and the mortality of pregnant woman and fetus pre and post treatment between the two groups were recorded and compared. Results: The mortality rates of pregnant women and fetus in the observation group was 4.44% 15.56%, and they were 7.50% and 20% in control group, respectively. The difference of mortality rate between the two groups were no significant. The APACHE Ⅱ score, MODS score, the serum levels of glutamic pyruvic transaminase (ALT), total bilirubin (TBIL), serum amylase (AMS), urea nitrogen (BUN) and creatinine (SCr) of observation group were significantly lower than that of control group at 72h after the treatment (t=11.13, t=9.79, t=17.79, t=12.55, t=10.13, t=15.25, t=12.29, P<0.05), while the PaO2/FiO2of observation group were significantly higher than that of control group at 72h after the treatment (t=11.44, P<0.05). Besides, the serum tumor necrosis factor alpha (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8), procalcitonin (PCT), and C reactive protein (CRP) of observation group were significantly lower than those of control group at 72h after the treatment (t=17.25, t=14.29, t=12.44, t=11.29, t=13.44, P<0.05). Conclusion: CBP can effectively improve the clinical symptoms of patients with pregnancy complicating with SAP, and protect function of important organs, and improve blood biochemical indexes and remove inflammatory medium. Therefore, CBP is effective method which cure pregnancy complicating SAP, and it can effectively improve the state of this disease.
ABSTRACT
Objective To analyze the clinical manifestation and therapeutic method in patients with acute mushroom poisoning. Methods A retrospective study was conducted. The clinical data of 48 patients with acute mushroom poisoning admitted to Department of Poisoning Treatment of the 307th Hospital of PLA from January 2016 to May 2017 were analyzed. The clinical data including gender, age, clinical symptoms, onset season, initial symptoms, incubation time, the length of hospital stay, treatment, and prognosis. In addition to the conventional treatment, the patients with severe liver damage were treated with continuous blood purification (CBP). The changes in routine blood test, biochemical parameters, blood ammonia and coagulation function before and 1, 3 and 7 days after CBP were observed. Results There were 29 of male (60.4%) and 19 of female (39.6%) in 48 patients with acute mushroom poisoning, with an average age of (48.10±13.14) years. There were 9 patients suffering from gastroenteritis type, 26 suffering from liver damage type, 8 suffering from neuro-psychosis type, 2 suffering from hemolytic type, and 3 suffering from renal damage type. All of the poisoned patients had evident seasonal characteristic, mainly concentrated in the autumn, especially in August, according for 66.7% (32/48). The initial symptoms of poisoning patients were mainly manifested as nausea and vomiting (50.0%). In five kinds of poisoned patients, the incubation time [(1.44±1.15) hours] and the length of hospital stay [(3.50±2.33) days] of neuro-psychosis type was the shortest, and the incubation time of liver-damaged type [(10.63±3.50) hours] and the length of hospital stay of renal damage type [(20.67±0.58) days] was the longest. Patients received symptomatic treatment according to different types, among whom 12 patients with severe liver damage received additional treatment for CBP. After the treatment, alanine aminotransferase (ALT), aspartate aminotransferase (AST), MB isoenzyme of creatine kinase (CK-MB), lactate dehydrogenase (LDH), and prothrombin activity (PTA) were significantly improved as compared with those before CBP treatment, with significant differences between 7 days after CBP and before CBP [ALT (U/L): 213.08±127.30 vs. 2 766.83±1 909.66, AST (U/L): 50.00 (41.00, 85.00) vs. 2 142.00 (1 225.00, 3 126.00), CK-MB (U/L): 24.09±8.87 vs. 44.75±22.09, LDH (μmol·s-1·L-1):3.70±1.46 vs. 13.03±12.77, PTA: (79.08±24.29)% vs. (35.25±19.85)%, all P < 0.01]. Among 48 patients, 47 were cured and discharged, and 1 patient with liver failure died due to aggravation of liver dysfunction, abnormal coagulation and bleeding, and massive hemorrhage of gastrointestinal tract. Conclusions Acute mushroom poisoning patients demonstrated obvious seasonal characteristics, mostly liver-damaged type, and its initial symptoms were mainly presented as nausea, vomiting and other gastrointestinal manifestations. Early clarification of diagnosis, timely treatment, as well as providence with CBP treatment in severe patients should be carried out as soon as possible. In such a way the curative effect can be enhanced, the mortality can be reduced, and the prognosis of the patients could be improved.
ABSTRACT
Objective To investigate the clinical efficacy and safety of continuous blood purification (CBP) in the treatment of severe sepsis in infants. Methods A retrospective analysis of 40 infants with severe sepsis treated with CBP was performed at PICU of Hunan Children's Hospital from January 2014 to July 2017,and 50 infants with severe sepsis who were not treated with CBP at the same period were enrolled as control group. The indicators included blood gas analysis,lactic acid (Lac),blood glucose,electrolytes, blood routine,C-reaction protein ( CRP) and procalcitonin ( PCT),alanine aminotransferase ( ALT) and aspartate aminotransferase (AST),total bilirubin(TB),urea nitrogen (BUN),serum creatinine (Scr) and creatine kinase isoenzyme MB (CK-MB),pediatric critical illness score (PCIS). Results (1) After 3 days of treatment,the recovery of body temperature,heart rate,respiratory rate and blood pressure in CBP group were better than those in the control group,and the differences between two groups were statistically signifi-cant(P < 0. 05). (2) After treatment,the levels of base excess(BE),Lac,white blood cell (WBC),PCT, CRP,ALT,AST,TB and BUN of CBP group recovered better than those of the control group,the differences were statistically significant (P < 0. 05). (3) The ΔPCIS (D3-D1) of CBP group was higher than that of the control group,and the difference between two groups was statistically significant (P < 0. 05). (4) The fatali-ty rate of CBP group was lower than that of the control group,and there was no significant difference between two groups (P > 0. 05). (5) Two cases of thrombocytopenia,2 cases of femoral vein thrombosis,2 cases of hypovolemic shock,and 1 case of blood coagulation in filter happened in CBP gruop,all cases had no punc-ture site infection. Conclusion CBP can improve the vital signs,internal environment,inflammatory reaction and organ function of infants with severe sepsis,and the effect is better than that of traditional methods. The complications of CBP in infants with severe sepsis are relatively large,so we should strictly master the indica-tions of CBP in the treatment of severe sepsis in children.
ABSTRACT
In recent years, with the great development of knowledge in pathophysiology and the improvement of medical technologies and products,we have further deepened our understanding in the princi-ples and patterns of continuous blood purification(CBP)technology. Nowadays,experts both domestic and foreign have been advocating the application of a combined CBP,which means two or more different blood purification principles or techniques combine ( or integrate) together so we can achieve different blood purifi-cation purposes and relieve or cure diseases. This document introduced the main trend and advanced technolo-gies of CBP used in critical care medicine,such as double filtration plasmapheresis and immunoadsorption.
ABSTRACT
Objective To observe the changes of serum phosphorus level in critically ill children during con-tinuous blood purification therapy(CRRT)in order to improve the monitoring of serum phosphorus and guide the sup-plementation of phosphorus during CRRT in critically ill children.Methods The patients who received CRRT from January to June 2017 in Pediatric Intensive Care Unit of Beijing Children's Hospital Affiliated to Capital Medical Uni-versity were selected as subjects.The changes of serum phosphorus before and 24 h,48 h,72 h after treatment of CRRT in the patients were observed and recorded respectively.Results Thirty-two patients were enrolled in this study.The serum phosphorus were(0. 91 ± 0. 50)mmol/L,(0. 54 ± 0. 20)mmol/L,(0. 39 ± 0. 18)mmol/L,(0. 36 ± 0.19)mmol/L before and 24 h,48 h,72 h after treatment of CRRT.There were significant differences of serum phos-phorus in the critically ill children before and after CRRT(t=3.310,4.602,4.399,all P<0.01).All patients were accompanied with hypophosphatemia after 24 h treatment,and the absolute values of serum phosphorus reduction(△P) were(0.40 ± 0.39)mmol/L,(0.15 ± 0.05)mmol/L,(0.09 ± 0.02)mmol/L in every 24 hours during CRRT.The first 24 h was the fastest changing phase for serum phosphorus,and the differences of △P between the 24 h and the 48 h,the 72 h after CRRT were statistically significant respectively(t=2.598,3.278,all P<0.05).The serum phos-phorus was sharply decreased in the 24 h of CRRT in patients with normal serum phosphorus before CRRT,and the differences were statistically significant(all P<0.01);but this phenomenon was not seen in hypophosphatemia group (all P>0.05).Conclusion In the process of CRRT,the change of serum phosphorous may be dose-dependent and closely related to the treatment phase of CRRT.So a titration of phosphorus supplementation as a nutritional support strategy should be considered.
ABSTRACT
Objective To study the influence of continuous blood purification(CBP) on cardiac out-put of pediatric patients using bioreactance. Methods Patients underwent CBP in PICU and nephrology ward from March 2014 were prospectively enrolled after approval by ethics committee. CBP therapies were all performed by Fresenius Medical Care hemodialysis machine. Cardiac output values were obtained using the non-invasive cardiac output monitoring ( NICOM) device ( Cheetah Medical). Blood pressure, heart rate, cardiac index(CI) and stroke volume index(SVI) were recorded before the therapy,at the beginning of ther-apy,during the course of therapy,and at the end of each therapy. Results Twenty-one pediatric patients (from 1. 0 year to 15. 5 years) were recruited and 69 treatments were recorded from March 2014 to Decem-ber 2016. The basic CI was 3. 4 (2. 4,6. 1) L/(min·m2),basic SVI was 43 (26,75) ml/(m2·beat). Dur-ing the beginning of therapy,mean arterial pressure(MAP),CI and SVI all dropped from the baseline ( P<0. 001),whereas heart rate increased. During the course of CBP,CI and SVI (were both recorded every 4 hours) kept on dropping and stayed at a relatively lower level. Course CI was 3. 0 (2. 4,4. 6) L/(min·m2) and course SVI was 28 (21,57) ml/(m2·beat). At the end of therapy,CI was 3. 4 (2. 5,5. 3) L/(min· m2),with no significant difference from the baseline CI (P＝0. 073). However,the SVI at the end of therapy was 35 (25,67) ml/(m2·beat),higher than the course SVI but still lower than the basic SVI,the differences were statistically significant ( P<0. 05). Conclusion CI and SVI continue to decline at the beginning of CBP treatment and remain at a lower level throughout the course of treatment. After the therapy, CI has returned to the basic level whereas SVI has not recovered.
