背景

嬰兒右鎖骨下靜脈置管的最佳插入長度尚不明確。本研究對年齡<1歲的兒童,根據體表標誌和線性迴歸模型的估計,進行回顧性比較了右鎖骨下靜脈置管最佳插入長度。

方法

分析了50例右鎖骨下靜脈置管術的患兒。標記相關距離為:從針插入點(I)到右鎖骨胸骨頭尖端(A),從A到雙乳頭連線的垂直線中點為(B)。透過回顧術後胸片,確定最佳插入長度。使用根據體表標誌的方程(IA+AB-截距)和線性迴歸模型的估計值與最佳插入長度進行比較。HOLIDAY

主要結果

根據體表標誌的方程為IA + AB - 5mm。根據體表標誌的估計和最佳插入長度之間的平均差異為1。0 mm(95%的一致性界限-18。2至20。3 mm)。線性迴歸模型(26。681 - 4。014×體重+ 0。576× IA + 0。537 ×AB - 0。482×月齡)與最佳插入長度的平均差異為0 mm(95%的一致性界限-16。7 -16。7 mm)。使用這兩種方法的估計值之間的差異不顯著。

結論

一個簡單的根據體表標誌的方程可有助於估計:年齡<1歲的患兒,接受右鎖骨下靜脈插管的最佳插入長度。

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。
