Objective To explore the clinical effect of hemoperfusion (HP) in cardiopulmonary bypass (CPB) on postoperative inflammation in patients with acute type A aortic dissection (AAD). MethodsAdult patients with AAD who planned to undergo total aortic arch replacement from July 2020 to November 2021 were continuously enrolled in our heart center. Patients were randomly divided into a HP group and a control (C) group. The HP group was treated with disposable HP device (Model: HA380, Zhuhai Jafron Biomedical, China) in CPB during the operation. ResultsFinally, 70 patients were included with 59 males and 11 females at an age range of 21-67 years. There were 35 patients in both groups. In this study, 3 patients died within 3 days after surgery, 2 in the HP group and 1 in the C group, and the remaining 67 patients survived to the follow-up end point (30 days after surgery). There was no statistical difference in preoperative baseline data, operative method, CPB time, block time, or other intraoperative data between the two groups. Blood product dosage, intubation time, hospital stays, and hospitalization expenses were similar between the two groups. Intraoperative hemoglobin (82.70±2.31 g/L vs. 82.50±1.75 g/L, P=0.954] and platelet concentration [(77.87±7.99)×109/L vs. (89.17±9.99)×109/L, P=0.384] were not statistically different between the HP group and C group. In the HP group, postoperative (ICU-12 h) interleukin-6 (IL-6) [338.14 (128.00, 450.70) pg/mL vs. 435.75 (180.50, 537.00) pg/mL, P=0.373], IL-8 [35.04 (18.02, 40.35) pg/mL vs. 43.50 (17.70, 59.95) pg/mL, P=0.383], and IL-10 [21.19 (6.46, 23.50) pg/mL vs. 43.41 (6.34, 50.80) pg/mL, P=0.537] were slightly lower than those in the C group, and the difference was not statistically different. The incidences of pulmonary infection (0.00% vs. 11.76%, P=0.042) and liver injury (2.94% vs. 20.58%, P=0.027) in the HP group were significantly lower than those in the C group, and the incidence of other postoperative complications, such as arrhythmia, nervous system complications and urinary system complications, showed no statistical difference between the two groups. Conclusion HP therapy in CPB is safe, but its effect on reducing postoperative inflammatory factors, postoperative inflammatory reactions and postoperative complications in the patients with AAD is limited, and it may be of application value to some high-risk patients with lung and liver injury.
We established acute cholangitis and endotoxiemia in 18 rabbits by ligating the common bile duct and injecting E coli(O111B4 strain)into the common bile duct. After perfusion through activated charcoal via femoral artery-vein pathway, the average blood levels of endotoxin decreased sighificantly from 2.24Eu/ml to 0.17Eu/ml(Plt;0.001). This result suggested that blood perfusion through activated charcoal may be a promising therapy for acute endotoxemia.
Objective
To investigate the therapeutic effect of continuous renal replacement therapy (CRRT) plus hemoperfusion (HP) on patients with diabetes and uremic encephalopathy.
Methods
Fifty-five patients with diabetes and uremic encephalopathy from January 2010 to December 2017 were retrospectively collected in this study and divided into CRRT plus HP (CRRT+HP) group (n=28) and hemodialysis (HD) plus HP (HD+HP) group (n=27). The changes of vital signs, related biochemical indicators before and after treatment and curative effects were compared between the two groups.
Results
The two groups were comparable in general. No significant differences were found in blood pressure or heart rate before and after treatment between the two groups (P>0.05). The incidence of hypotension events in CRRT+HP group was significantly lower than that in HD+HP group (P<0.05), and the effective rate of cardiac function improvement in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05). After treatment, the blood urea nitrogen, creatinine, parathyroid hormone, β2-microglobulin, phosphorus, C-reactive protein and brain natriuretic peptide in the two groups were significantly decreased than those before treatment (P<0.05). Parathyroid hormone, β2-microglobulin, C-reactive protein and brain natriuretic peptide were significantly decreased in CRRT+HP group as compared with those in HD+HP group (P<0.05). The remission rate of uremic encephalopathy in CRRT+HP group was significantly higher than that in HD+HP group (P<0.05).
Conclusions
As compared with HD+HP pattern, CRRT+HP pattern is more stable in the hemodynamics, and more effective in the improvement of heart failure and the clearance of inflammatory mediators, middle molecular and macromolecular substances associated with uremic encephalopathy. CRRT+HP pattern is suitable for the treatment of patients with diabetes and uremic encephalopathy.
Objective To evaluate the effect of hemoperfusion for absorption of inflammatory cytokines on sepsis . Method A prospective randomized controlled study was carried out to collect 60 sepsis patients admitted to the Department of Critical Care Medicine of this hospital from June 2019 to December 2021. They were randomly divided into a study group (30 cases) and a control group (30 cases) by using the random number table method. Both groups of patients received routine treatment according to the guidelines, including fluid resuscitation, mechanical ventilation, antibiotic and vasoactive agents. For the patients with renal failure, renal replacement therapy (RRT) was used. Routine vital sign monitoring and serum procalcitonin (PCT) and interleukin-6 (IL-6) determination were recorded. The study group received two times of hemoperfusion to absorb inflammatory cytokines at 0 h and 24 h after enrollment. At 24 h and 48 h after treatment, the vital signs and related physical and chemical indexes of patients were recorded again, including norepinephrine dose, oxygenation index, PCT, IL-6 and blood lactic acid. The changes of physical and chemical indexes and the 28-day survival rate of the two groups were compared. Results There was no difference in the general situation of the two groups when they were enrolled (P>0.05). The dosage of norepinephrine [(0.77±0.48)μg·kg–1·min–1 vs. (0.92±0.62) μg·kg–1·min–1, P=0.030] and the level of blood lactic acid [(2.70±1.43)mmol/L vs. (4.05±2.60)mmol/L, P=0.001] in the study group were significantly lower than those in the control group 24 h and 48 h after treatment. The oxygenation index in the study group was higher than that of the control group 24 h after treatment (212±68)mm Hg vs. (197±42)mm Hg, P=0.042). The inflammation related indexes PCT [(17±24)ng/mL vs. (32±36)ng/mL, P=0.013] and IL-6 [299 (102, 853)pg/mL vs. 937 (247, 2230)pg/mL, P=0.026] in the study group were significantly lower than those in the control group 48 h after treatment. The dosage of noradrenaline, oxygenation index, PCT, IL-6 and blood lactate level in the study group after treatment were improved compared with those before treatment (P<0.05), while those in the control group were not significantly improved after treatment (P>0.05), and oxygenation index in the two groups had no significant difference before and after treatment (P>0.05). There was no significant difference in the 28-day survival rate between the two groups (χ2=0.211, P=0.646). Conclusion Although the hemoperfusion for absorption of inflammatory cytokine factors can not reduce the 28-day mortality of sepsis, it can significantly improve the early physical and chemical indicators of patients, and provide opportunities for follow-up treatment.
Objective To explore the safety and efficacy of regional citrate anticoagulation in hemoperfusion combined with continuous renal replacement therapy (CRRT). Methods Patients who underwent continuous veno-venous hemodiafiltration tandem hemoperfusion between January 2021 and March 2022 in West China Hospital of Sichuan University were retrospectively enrolled. All patients received double-lumen catheter indwelling through internal jugular vein or femoral vein for vascular access, and were treated with Prismaflex V8.0 CRRT machine, extracorporeal circulation line ST150, and disposable hemoperperfusion device HA380. Four percent sodium citrate was pumped from the arterial end at the rate of 180-200 mL/h. The blood pump rate was 130-150 mL/min, the ratio of dialysis fluid to the dose of replacement fluid was 1∶1, the amount of CRRT treatment agent was 20-35 mL/(kg·h), replacement fluid was added by post-dilution method, and the treatment time of hemoperfusion was 8-10 h. The dialysis treatment completion rate, the cardiopulmonary bypass life, the incidence of coagulation events, and the levels of procalcitonin, C-reactive protein, interleukin-6, etc. were observed. Results A total of 143 cases of treatment were completed in 75 patients, among them, 119 cases were successfully completed and the completion rate of hemoperfusion treatment was 83.2%. The average life of hemoperfusion devices was (8.5±1.5) h. Bleeding or blood clotting occurred in 18.9% of the treatment (27/143), 13 cases had CRRT extracorporeal circulation coagulation, 11 cases had hemoperfusion device coagulation, and 3 cases had gastrointestinal bleeding. The ionic calcium levels after the filter of 93 cases of treatment were maintained around 0.25-0.35 mmol/L, and the peripheral calcium levels were maintained around 1.0-1.1 mmol/L. Compared with that at 0 h, the procalcitonin decreased significantly 72 h after hemoperfusion treatment (P=0.014), while there was no significant change in interleukin-6 or C-reactive protein after 72 h treatment (P>0.05). None of the patients experienced anaphylaxis during treatment. Conclusion In CRRT combined with hemoperfusion, the use of regional citrate anticoagulation results in good cardiopulmonary bypass life, inflammatory mediators clearance, and a lower risk of bleeding.
