目的在PICU试用小儿危重评分。方法141例ICU患者于入院1、3、7d作小儿危重评分，同时记录设备利用、费用、院内感染、抗生素应用等情况。结果将评分从高至低分为～100、～80、～70三组（非危重、危重、权危重），病死率依次为8．2％、36．4％、50％，差异非常显著（P＜0．001）。1、3、7d评分死亡与存活组间有非常显著差异（P＜0．0001），危重评分上升，病死率明显下降（P＜0．05）。危重、极危重组与非危重组比较其使用ICU设备的时间明显增加（P＜0．01），设备利用率显著上升（P＜0．0001）；其应用高级抗生素及主要住院费用显著增多（P＜0．01、P＜0．001）。结论小儿危重评分可客观、准确评估病情和预后，同时在评估和比较ICU的设备利用、药物治疗、医疗费用、效率和医护质控等方面有广泛应用。
PURPOSE: To assess pediatric critical mass score at PICU. Methods One hundred and seventy-one ICU patients were scored for pediatric risk scores on the 1st, 3rd, and 7th days after admission, and equipment utilization, cost, nosocomial infection and antibiotic application were recorded. Results The scores were divided into high, low, low, high and low groups of 100, 80, and 70 (non-critically ill, critically endangered and critically weighted) with mortality rates of 8.2%, 36.4% and 50% P <0.001). There were significant differences (P <0.0001) between the death and survival groups on the 1st, 3rd and 7th day, the critical score increased and the case fatality rate decreased significantly (P <0.05). The time to use ICU equipment in critically ill, critically ill and critically ill patients was significantly increased (P <0.01), and the equipment utilization rate was significantly increased (P <0.0001). The use of advanced antibiotics and major hospitalization expenses increased significantly (P < P <0.01, P <0.001). Conclusion The score of critical illness in children can objectively and accurately assess the condition and prognosis. At the same time, it is widely used in the evaluation and comparison of equipment utilization, drug treatment, medical expenses, efficiency and quality control of ICU.
