Objective:To explore the role of continuous renal replacement therapy (CRRT) combined with extracorporeal carbon dioxide removal (ECCO 2R) in the treatment of children with respiratory failure. Methods:The clinical data of 12 children with respiratory failure who were treated with CRRT+ECCO 2R in PICU of Jinan Children's Hospital from July 2020 to August 2022 were collected and analyzed retrospectively. The outcomes and the external pipeline usage of the patients were observed, and the blood gas analysis and ventilator parameters before 1 h and after 1, 6, 12 and 24 h of the treatment were compared by one-way ANOVA with LSD post hoc correction. Results:Six patients successfully withdrew from CRRT+ECCO 2R and mechanical ventilation, three patients were transferred to ECMO treatment. Three cases died after voluntary withdrawal of treatment, and two cases died due to treatment failure. The mortality rate was 41.7%. After continuous treatment of CRRT+ECCO 2R for 15 to 112 h, two cases experienced extracorporeal circuit obstruction. After 1 h of treatment, PaCO 2 decreased from (64.67±24.4) mmHg to (49.42±15.54) mmHg, pH increased from (7.28±0.20) to (7.38±0.11), FiO 2 decreased from (0.85±0.13) to (0.78±0.15), PC decreased from (19.42±4.34) cmH 2O to (17.75±4.00) cmH 2O. After 24 h of treatment, PaCO 2 decreased to (39.2±5.55) mmHg, pH increased to (7.41±0.04), FiO 2 decreased to (0.46±0.11), and PC decreased to (13.8±3.36) cmH 2O, and the differences were statistically significant compared with before treatment ( P < 0.05). Conclusions:The combination of CRRT and ECCO 2R therapy can safely substitute for partial lung ventilation/perfusion function, and play a role in protecting right heart function and improving lung-kidney interaction. It can be considered as an option for extracorporeal respiratory, circulatory, and renal support, and consequently has broad prospects.

Objective:To investigate the practical effect of implementation of standardized management for children asthma.Methods:Through regular activity of"Asthmatic Home",children asthma control table(C-ACT) was used to investigate the asthmatic children's disease control before and after treatment respectively.The children's parents' psychological conditions were investigated by symptom checklist(SCL-90).General practitioners were trained,and the behavior(life quality),the score change of the parents SCL-90,parents' awareness of asthma,the general practitioners' asthma management knowledge were compared before and after standardized management.Results:After the standardized management of children's asthma,the life quality of children and the parents' social psychological condition were improved.The general practitioners got more understanding of GINA program and update of asthma knowledge.Conclusions:Through the implementation of standardized management of children's asthma,the parents got the education of disease-related knowledge.The primary general practitioners' standardized management controlled the children's asthma effectively,and improved the children's quality of life.
