血管活性药物评分与儿童脓毒性休克预后的关系

目的 探讨血管活性药物评分（VIS）与脓毒性休克患儿预后的关系。方法 以接受血管活性药物治疗的117例失代偿型脓毒性休克患儿为研究对象，根据预后分为死亡组（41例）和存活组（76例），根据第1个24 h最大VIS （24 h VIS max）的临界点分为低VIS组（78例）和高VIS组（39例）。计算所有患儿24 h VIS max和第1个24 h VIS平均值（24 h VIS mean），并对VIS与脓毒性休克预后的关系进行受试者工作特征曲线（ROC）分析。结果 死亡组24 h VIS max、24 h VIS mean、PRISMⅢ评分、血管活性药物使用前及24 h后的乳酸均明显高于存活组（P < 0.05）。24 h VIS max、24 h VIS mean、PRISMⅢ评分、血管活性药物使用前和24 h后的乳酸以及24 h后的pH对于脓毒性休克预后均具有一定的预测价值，但以24 h VIS max的曲线下面积（AUC）最大（P < 0.05）。高VIS组的死亡人数、PRISM Ⅲ评分、治疗前及治疗24 h后的乳酸均明显高于低VIS组（P < 0.05）。结论 血管活性药物评分与脓毒性休克患儿的病死率有关，血管活性药物评分越高，病情越危重，病死率越高。

Association between vasoactive-inotropic score and prognosis in children with septic shock

Objective To investigate the association between vasoactive-inotropic score (VIS) and prognosis in children with septic shock.Methods A total of 117 children with decompensated septic shock who received the treatment with vasoactive agents were enrolled. According to their prognosis, they were divided into death group with 41 children and survival group with 76 children. With the maximum VIS within the first 24 hours (24hVIS max) as the cut-off value (29.5), the children were divided into low VIS group with 78 children and high VIS group with 39 children. The 24hVIS max and the mean VIS within the first 24 hours (24hVIS mean) were calculated for all children. A receiver operating characteristic (ROC) curve analysis was performed for the association between VIS and the prognosis of septic shock.Results Compared with the survival group, the death group had significantly higher 24hVIS max, 24hVIS mean, PRISM Ⅲ score, and level of lactate before the use of vasoactive agents and after 24 hours of use (P < 0.05). 24hVIS max, 24hVIS mean, PRISM Ⅲ score, level of lactate before the use of vasoactive agents and after 24 hours of use, and 24-hour pH had a certain value in predicting the prognosis of septic shock, but 24hVIS max had the largest area under the ROC curve. Compared with the low VIS group, the high VIS group had significantly higher number of deaths, PRISM Ⅲ score, and level of lactate before treatment and after 24 hours of treatment (P < 0.05).Conclusions VIS is associated with the mortality of children with septic shock, and the severity and mortality of patients increase with the increase in VIS.
