Objective To investigate the influence of blood transfusion timing on blood transfusion efficacy and clinical prognosis in children under the strain of blood bank resources during COVID-19 pandemic. Methods This retrospective cohort study included clinical outcomes of pediatric emergency patients who applied for blood transfusion in Guangzhou Women and Children's Hospital from January 2020 to December 2020. Results A total of 566 children applicated blood transfusion for red blood cells and platelets for non-emergency surgical use were enrolled, including 260 red blood cells cases and 306 platelets cases. Among the 260 applications for red blood cells, 209 cases received timely transfusion, 40 cases received delayed transfusion, and 11 cases did not receive transfusion.The effective rate of transfusion for red blood cells was 37.8% in the timely group and 35.0% in the delayed group (P=0.737). One death case with poor prognosis was found in the timely transfusion group, and the clinical prognosis of the rest cases was good. There was no statistical difference in the clinical outcomes among the three groups (P=0.886). Among 306 applications for platelet, 195 cases had timely transfusion, 108 cases had delayed transfusion, and 13 cases did not had transfusion.One case with poor prognosis died in the timely transfusion group (0.51%), and three with poor prognosis died in the delayed transfusion group (2.78%). The rest of the cases had good clinical prognosis, and there was no statistical difference in clinical outcomes among the three groups (P=0.131). Conclusions There were no significant differences in clinical outcomes among the timely transfusion group, the delayed transfusion group, and the non-transfusion group for red blood cell and platelet transfusion respectively. The timing of transfusion may need to be determined by evidence-based studies with large samples.

目的 探讨健康儿童的个体因素对超声测量下腔静脉内径的影响。方法 使用超声测量210例健康儿童的下腔静脉呼气末内径及腹主动脉内径,并记录他们的个体特征,包括性别、年龄、身高、体质量、腰围、体表面积等,进行相关与回归分析。结果 年龄、身高、体质量、腰围、体表面积与下腔静脉和腹主动脉内径呈正相关。年龄是女性儿童下腔静脉内径唯一的独立影响因素,身高是男性儿童下腔静脉内径唯一的独立影响因素。无论男性或女性,年龄是儿童腹主动脉内径的独立影响因素,而下腔静脉和腹主动脉内径的比值不受这些个体因素的影响。结论 下腔静脉和腹主动脉内径易受个体因素影响,而它们的比值不易受个体因素影响,可以更好的用于预测儿童的容量特征。

Objective To explore the impact of individual characteristics on inferior vena cava diameter ( IVC ) in healthy children. Methods IVC_max and abdominal aorta (AO) diameters were measured by ultrasound in 210 healthy children. The individual characteristics including gender, age,height,weight, waist circumference of each child were recorded. Then the surface area(BSA) and IVC_max/AO were calculated to discuss the relationship between them with multivariate analysis. Results Age, height, weight,waist circumference, and BSA were positively correlated with IVC_max and AO. Multivariate linear regression showed that age was the only independent variable for IVC_max in female children, height was the only independent variable for IVC_max in male children, and age was the only independent variable for AO in both females and males. IVC_max/AO was not significantly influenced by the subjects' characteristics. Conclusion IVC_max and AO were more susceptible to subjects' characteristics than IVC_max/AO. IVC_max/AO could be a reliable and practical parameter in children as it was independent of age, height, and weight.

目的 通过血常规分析和C反应蛋白(CRP)水平检测,探讨其对儿童甲型和乙型流感的辅助诊断价值,为临床治疗提供参考依据。方法 选择3 069名甲型流感患儿、2 307名乙型流感患儿、855名健康儿童,统计分析血常规参数以及CRP水平。采用ROC曲线分析血常规对甲乙型流感的区分效能。结果 甲组白细胞计数(WBC)均值高于正常组,乙组则相反,甲乙组中性粒细胞百分比(Neut%)、中性粒细胞与淋巴细胞百分比比值(NLR)、单核细胞百分比(Mono%)的均值高于正常组,甲乙组淋巴细胞百分比(Lymph%)、血小板计数(PLT)的均值低于正常组。甲组中性粒细胞计数(Neut#)、单核细胞计数(Mono#)、CRP、PLT的均值均高于乙组,Lymph%和淋巴细胞计数(Lymph#)的均值低于乙组。甲组在WBC>13×10⁹/L、Neut%>70.7、Lymph%<19.1的构成比高于乙组。NLR预测甲型流感临界值为2.08(敏感度为75.9%,特异度为89.4%),预测乙型流感临界值为2.11(敏感度为50.5%,特异度为89.8%)。结论 血常规参数和CRP水平变化可用于判断流感患儿是否存在细菌感染,指导临床用药;NLR作为一种新型预测标志物,其变化可以对区分甲型、乙型流感,尤其是甲型流感具有临床价值。

Objective Through blood analysis and C-reactive protein (CRP) level detection, to explore its value in the auxiliary diagnosis of influenza A and B in children, and to provide reference for clinical treatment. Methods 3 069 children with influenza A, 2 307 children with influenza B, and 855 healthy children were selected, and blood routine parameters and CRP levels were statistically analyzed. The ROC curve was used to analyze the discriminatory efficacy of blood routine on influenza A and B. Results The mean value of white blood cell count (WBC) in group A was higher than that in normal group, but in group B it had the opposite result. The percentage of neutrophils (Neut%), the ratio of neutrophils to lymphocytes (NLR), and the percentage of monocytes (the mean value of Mono%) is higher than that of normal group, and the mean value of lymphocyte percentage (Lymph%) and platelet count (PLT) of group A and B is lower than that of normal group. The mean values of neutrophil count (Neut#), monocyte count (Mono#), CRP and PLT in group A were higher than those in group B, and the mean values of Lymph% and lymphocyte count (Lymph#) were lower than those in group B. The composition ratios of group A in WBC>13×10⁹/L, Neut%>70.7, Lymph%<19.1 were higher than that in group B. The NLR predicted the critical value of influenza A was 2.08 (sensitivity 75.9%, specificity 89.4%), and the predicted influenza B threshold value was 2.11 (sensitivity 50.5%, specificity 89.8%). Conclusion Changes in blood routine parameters and CRP levels can be used to determine whether there is a bacterial infection in children with influenza and to guide clinical medication; NLR as a new predictive marker, its changes can distinguish influenza A or B. Especially in influenza A determination, it has clinical value.
