目的 探讨在COVID-19流行期间血库资源紧张状态下输血时机对儿童输血效果及临床预后的影响。方法 本回顾性队列研究纳入2020年1月—2020年12月在广州市妇女儿童医疗中心儿科急诊就诊并申请输血的患儿的临床预后。结果 共566例发起红细胞和血小板的非手术输血申请的患儿纳入研究,包括 260 例的红细胞申请和306例血小板申请。260份红细胞申请中:209 例及时输血,40 例延时输血,11 例未输血;及时组和延时组的输血有效率分别为37.8%和35.0%(P=0.737);1名不良预后的死亡病例出现在及时组中,余病例临床预后均良好,3组的临床结局无统计学差异(组间P=0.886)。306份血小板申请中:195 例及时输血,108 例延时输血,3例未输血;1名不良预后的死亡病例出现在及时组中(0.51%),3名不良预后的死亡病例出现在延时组中(2.78%),余病例临床预后均良好,3组的临床结局无统计学差异(组间P=0.131)。结论 符合红细胞与血小板输血指征的非急诊手术用血的急诊患儿中,及时组、延时组和未输血组之间的临床结局没有差异。输血时机进一步需要大样本的循证研究加以确定。

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 比较经阴道射频刀消融和经皮微波消融治疗单发黏膜下型子宫肌瘤短期临床效果的差异。方法 回顾性分析2013年3月—2014年3月21例经阴道射频刀消融治疗单发黏膜下型子宫肌瘤和 24 例经皮微波消融治疗单发黏膜下型子宫肌瘤的临床资料。结果 经阴道射频刀消融治疗单发黏膜下型子宫肌瘤和经皮微波消融治疗单发黏膜下型子宫肌瘤的临床结果差异有统计学意义(P＜0. 05) ,手术时间分别为(50.8±10.7)min,(60.4±11.3)min,术后住院时间为(2.5±1.2)天,(4.7±0.8)天。结论 经阴道射频刀消融术及经皮微波消融术治疗单发黏膜下型子宫肌瘤都使瘤体缩小并取得良好的短期临床效果,各有优、缺点,临床应视瘤体的具体情况选择。
