背景
婴儿右锁骨下静脉置管的最佳插入长度尚不明确。本研究对年龄<1岁的儿童,根据体表标志和线性回归模型的估计,进行回顾性比较了右锁骨下静脉置管最佳插入长度。

方法
分析了50例右锁骨下静脉置管术的患儿。标记相关距离为:从针插入点(I)到右锁骨胸骨头尖端(A),从A到双乳头连线的垂直线中点为(B)。通过回顾术后胸片,确定最佳插入长度。使用根据体表标志的方程(IA+AB-截距)和线性回归模型的估计值与最佳插入长度进行比较。HOLIDAY
主要结果
根据体表标志的方程为IA + AB - 5mm。根据体表标志的估计和最佳插入长度之间的平均差异为1.0 mm(95%的一致性界限-18.2至20.3 mm)。线性回归模型(26.681 - 4.014×体重+ 0.576× IA + 0.537 ×AB - 0.482×月龄)与最佳插入长度的平均差异为0 mm(95%的一致性界限-16.7 -16.7 mm)。使用这两种方法的估计值之间的差异不显著。

一个简单的根据体表标志的方程可有助于估计:年龄<1岁的患儿,接受右锁骨下静脉插管的最佳插入长度。

A retrospective comparison for prediction of optimal length of right subclavian vein catheterization in infants: landmark-based estimation vs. linear regression model
Abstract
Background:The optimal insertion length for right subclavian vein catheterization in infants has not been determined. This study retrospectively compared landmark-based and linear regression model-based estimation of optimal insertion length for right subclavian vein catheterization in pediatric patients of corrected age < 1 year.
Methods:Fifty catheterizations of the right subclavian vein were analyzed. The landmark related distances were: from the needle insertion point (I) to the tip of the sternal head of the right clavicle (A) and from A to the midpoint (B) of the perpendicular line drawn from the sternal head of the right clavicle to the line connecting the nipples. The optimal length of insertion was retrospectively determined by reviewing post-procedural chest radiographs. Estimates using a landmark-based equation (IA + AB - intercept) and a linear regression model were compared with the optimal length of insertion.
Result:A landmark-based equation was determined as IA + AB - 5. The mean difference between the landmark-based estimate and the optimal insertion length was 1.0 mm (95% limits of agreement -18.2 to 20.3 mm). The mean difference between the linear regression model (26.681 - 4.014 × weight + 0.576 × IA + 0.537 × AB - 0.482 × postmenstrual age) and the optimal insertion length was 0 mm (95% limits of agreement -16.7 to 16.7 mm). The difference between the estimates using these two methods was not significant.
Conclusion:A simple landmark-based equation may be useful for estimating optimal insertion length in pediatric patients of corrected age < 1 year undergoing right subclavian vein catheterization.
