困难静脉通路评分在儿科外周静脉穿刺中的应用研究

Application of Difficult Intravenous Access Score in Paediatric Peripheral Venepuncture

目的验证困难静脉通路评分在儿科外周静脉穿刺中的有效性,探讨其在儿科静脉通路留置策略中的适用性。方法采用便利抽样法选取云南昆明一家三级甲等医院儿科的住院患儿作为研究对象。使用Riker的三变量儿童困难静脉通路评估工具(DIVA评分)对374名接受静脉穿刺置管的患儿进行评估。采用ROC曲线下面积、灵敏度、特异度和约登指数等指标对该工具的预测价值进行评价。结果DIVA评分与国外常模比较,差异无统计学意义(P>0.05)。研究中穿刺失败组与穿刺成功组患儿DIVA评分比较,差异有统计学意义(P<0.001)。随着DIVA评分由0递增至6,对应患儿的首次静脉穿刺成功率逐渐由92.9%下降至54.5%。DIVA评分ROC曲线下面积为0.648。当总分为3分时,量表预测价值最大。结论儿童三变量DIVA评分对儿童困难静脉通路有一定的识别能力且预测准确度较好,可用于儿科外周静脉穿刺前的评估。

Objective To verify the validity of difficult venous access score in pediatric peripheral venipuncture and explore its applicability in pediatric venous access indwelling strategy.Methods The convenience sampling method was used to select inpatients in the pediatric department of a tertiary hospital in Kunming,Yunnan Province as the research subjects.Riker’s three-variable pediatric Difficult Intravenous Access(DIVA)Assessment Tool was used to evaluate 374 children undergoing venipuncture catheterization.The predictive value of the tool was evaluated using indicators such as the area under the ROC curve,sensitivity,specificity,and Youden index.Results Comparing this DIVA score with Riker’s study,the difference was not statistically significant(P>0.05).In contrast,the difference in DIVA scores between the failed puncture group and the successful puncture group was statistically significant(P<0.001).As the DIVA score increased from 0 to 6,the first venipuncture success rate of the corresponding children gradually decreased from 92.9%to 54.5%.The area under the ROC curve of the DIVA score was 0.648.When the total score was 3 points,the scale had the greatest predictive value.Conclusion The three-variable DIVA score has a certain ability to identify difficult venous access in children.It has a good prediction accuracy,and can be used for evaluation before pediatric peripheral venipuncture.
