RESUMO
Objective:To explore the scope, mode, anticoagulation mode and complications of blood purification in children with acute and critical illness.Methods:A total of 377 times of treatment of 102 children treated with blood purification in PICU at the First Affiliated Hospital of Xinxiang Medical College from January 2018 to December 2020 were retrospectively analyzed.Results:Among 102 critically ill children treated with blood purification, acute and chronic renal failure ranked the first in terms of disease distribution, with 23 cases in total, followed by 16 cases of severe viral encephalitis (meningoencephalitis), 11 cases of septic shock, seven cases of acute poisoning, five cases of severe allergic purpura, five cases of necrotic encephalopathy.In terms of clinical prognosis, 51(50.0%) cases were cured, 29(28.4%) cases were improved, 10(9.8%) cases died, and 12 cases abandoned treatment.In 2019, the blood purification application frequency was the highest, with a total of 47 cases, which was higher than those in 2018 and 2020( P<0.05). Continuous veno-venous hemofiltration was used in the largest number of children, with a total of 56 cases.There was a statistically significant difference in the application ratio of this mode during 3 years ( P<0.05), while there was no statistically significant difference in the application ratio of other modes.In terms of the selection of anticoagulation methods, the proportions of systemic anticoagulation and extracorporeal anticoagulation had significantly difference among different years( P<0.05), and the application of extracorporeal anticoagulation had increased year by year.There was no statistically significant difference in the proportion of patients without anticoagulants.The incidence of complications of blood purification was the highest in 2019, with catheter related thrombus in the majority (30 person-times), followed by hypothermia, catheter filter coagulation, hematoma formation, catheter related infection, hypotension, heparin-induced thrombocytopenia, etc.There was statistically significant difference in the total complications among different years( P<0.05). Conclusion:Blood purification is widely used in children with acute and critical illness, with a variety of diseases.The most commonly used mode is continuous veno-venous hemofiltration and in vitro anticoagulation.Catheter-related thrombosis is the most common complication.
