Clinical application of plasma exchange combined with continuous veno-venous hemofiltration dialysis in children with refractory Kawasaki disease shock syndrome / 中国当代儿科杂志

OBJECTIVES@#To study the role of plasma exchange combined with continuous blood purification in the treatment of refractory Kawasaki disease shock syndrome (KDSS).@*METHODS@#A total of 35 children with KDSS who were hospitalized in the Department of Pediatric Intensive Care Unit, Hunan Children's Hospital, from January 2019 to August 2022 were included as subjects. According to whether plasma exchange combined with continuous veno-venous hemofiltration dialysis was performed, they were divided into a purification group with 12 patients and a conventional group with 23 patients. The two groups were compared in terms of clinical data, laboratory markers, and prognosis.@*RESULTS@#Compared with the conventional group, the purification group had significantly shorter time to recovery from shock and length of hospital stay in the pediatric intensive care unit, as well as a significantly lower number of organs involved during the course of the disease (P<0.05). After treatment, the purification group had significant reductions in the levels of interleukin-6, tumor necrosis factor-α, heparin-binding protein, and brain natriuretic peptide (P<0.05), while the conventional group had significant increases in these indices after treatment (P<0.05). After treatment, the children in the purification group tended to have reductions in stroke volume variation, thoracic fluid content, and systemic vascular resistance and an increase in cardiac output over the time of treatment.@*CONCLUSIONS@#Plasma exchange combined with continuous veno-venous hemofiltration dialysis for the treatment of KDSS can alleviate inflammation, maintain fluid balance inside and outside blood vessels, and shorten the course of disease, the duration of shock and the length of hospital stay in the pediatric intensive care unit.

Application of transport ventilator in the inter-hospital transport of critically ill children / 中国当代儿科杂志

OBJECTIVES@#To study the application value of transport ventilator in the inter-hospital transport of critically ill children.@*METHODS@#The critically ill children in Hunan Children's Hospital who were transported with or without a transport ventilator were included as the observation group (from January 2019 to January 2020; n=122) and the control group (from January 2018 to January 2019; n=120), respectively. The two groups were compared in terms of general data, the changes in heart rate, respiratory rate, and blood oxygen saturation during transport, the incidence rates of adverse events, and outcomes.@*RESULTS@#There were no significant differences between the two groups in sex, age, oxygenation index, pediatric critical illness score, course of disease, primary disease, heart rate, respiratory rate, and transcutaneous oxygen saturation before transport (P>0.05). During transport, there were no significant differences between the two groups in the changes in heart rate, respiratory rate, and transcutaneous oxygen saturation (P>0.05). The incidence rates of tracheal catheter detachment, indwelling needle detachment, and sudden cardiac arrest in the observation group were lower than those in the control group during transport, but the difference was not statistically significant (P>0.05). Compared with the control group, the observation group had significantly shorter duration of mechanical ventilation and length of stay in the pediatric intensive care unit and significantly higher transport success rate and cure/improvement rate (P<0.05).@*CONCLUSIONS@#The application of transport ventilator in the inter-hospital transport can improve the success rate of inter-hospital transport and the prognosis in critically ill children, and therefore, it holds promise for clinical application in the inter-hospital transport of critically ill children.

Application of double plasma molecular adsorption system in children with acute liver failure / 中国当代儿科杂志

OBJECTIVE@#To study the efficacy and safety of double plasma molecular absorption system (DPMAS) in the treatment of pediatric acute liver failure (PALF).@*METHODS@#A prospective analysis was performed on the medical data of children with PALF who were hospitalized in the Intensive Care Unit (ICU), Hunan Children's Hospital, from March 2018 to June 2020. The children were randomly divided into two groups:plasma exchange group (PE group) and DPMAS group (@*RESULTS@#Compared with the PE group, the DPMAS group had a significantly lower number of times of artificial liver support therapy and a significantly shorter duration of ICU stay (@*CONCLUSIONS@#DPMAS is safe and effective in the treatment of PALF and can thus be used as an alternative to artificial liver support therapy.

Clinical features of severe type 7 adenovirus pneumonia: an analysis of 45 cases / 中国当代儿科杂志

OBJECTIVE@#To study the clinical features of severe type 7 adenovirus pneumonia in children.@*METHODS@#A retrospective analysis was performed for the clinical data of children who were diagnosed with severe type 7 adenovirus pneumonia from February to June, 2019.@*RESULTS@#Among the 45 children, the male/female ratio was 3:2 and the median age was 14 months. All children had repeated fever, cough, and pulmonary moist rales, and the mean duration of fever was 14±4 days. The median time from fever to dyspnea was 8 days, and the time from fever to mechanical ventilation was 11.6±2.5 d. There was no significant increase in white blood cell count, with neutrophils as the main type. There were slight reductions in hemoglobin and albumin, while platelet and fibrinogen remained normal. There were increases in aspartate aminotransferase, lactate dehydrogenase, procalcitonin, and C-reaction protein. The detection rate of mixed pathogens was 84%. Effusion in both lungs was the major change on chest imaging (64%). Bronchoscopic manifestations were endobronchitis, tracheomalacia, and plastic bronchitis. The incidence rate of respiratory complications was 100%, and extrapulmonary complications mainly involved the circulatory system (47%), digestive system (36%), and nervous system (31%). Among the 45 children, 16 were administered with 400 mg/kg intravenous immunoglobulin (IVIG) daily for 5 days, with a mean duration of fever of 16±5 days, and 29 were administered with 1 g/kg IVIG daily for 2 days, with a mean duration of fever of 13±4 days; there was a significant difference in the mean duration of fever between the two groups (P=0.046). The overall mortality rate was 11%.@*CONCLUSIONS@#Severe type 7 adenovirus pneumonia in children has severe conditions, with a high incidence rate of complications and a high mortality rate, so it should be diagnosed and treated as early as possible.

Value of pancreatic stone protein/regenerating protein in severity evaluation and prognosis prediction for children with sepsis / 中国当代儿科杂志

<p><b>OBJECTIVE</b>To evaluate the value of pancreatic stone protein/regenerating protein (PSP/reg) in severity evaluation and prognosis prediction for children with sepsis.</p><p><b>METHODS</b>In this prospective case-control study, 159 children with sepsis (106 cases in the sepsis group; 53 cases in the severe sepsis group, including 12 cases of septic shock) and 20 children without sepsis (control group) were enrolled. ELISA was applied to measure plasma PSP/reg levels on days 1, 3, and 7 of admission to the PICU. The Spearman rank correlation test was applied to assess the correlations between plasma PSP/reg level and serum procalcitonin (PCT), CRP, WBC count, and pediatric critical illness score (PCIS). The area under the receiver operating characteristic curve (AUC) was used to assess the value of each index in determining severity and predicting prognosis for children with sepsis.</p><p><b>RESULTS</b>On day 1 of admission to the PICU, plasma PSP/reg levels in the sepsis and severe sepsis groups were significantly higher than in the control group (P<0.05), and the severe sepsis group had a significantly higher plasma PSP/reg level than the sepsis group (P<0.05). On day 1 of admission to the PICU, the survival group (n=132) had a significantly lower plasma PSP/reg level than the non-survival group (n=27) (P<0.05). On day 1 of admission to the PICU, plasma PSP/reg level in children with sepsis was positively correlated with WBC count and serum PCT level (rs=0.212 and 0.548, respectively; both P<0.05), and negatively correlated with PCIS score (rs=-0.373; P<0.05). The AUCs of plasma PSP/reg level and serum PCT for determination of severe sepsis, septic shock, and death were higher than 0.7 (P<0.05).</p><p><b>CONCLUSIONS</b>PSP/reg is closely related to infection, and has a certain clinical value in risk stratification of sepsis and prognosis evaluation.</p>
