Length-based dosing systems reduce errors associated with resuscitation drug dosing. Obese and thin children of the same length are dosed the same despite their different weights.
Length (height) and weight were measured in children after a body habitus icon assignment. Within each body habitus group, regression analysis was performed to generate a weight-estimation formula using body habitus and length (BHL). This BHL method was compared to the Broselow tape (BT).
Height and weight data were plotted to obtain visual scattergrams. Logarithmic regression yielded higher correlation coefficients than standard linear regression. Within body habitus groups, BHL epinephrine dose estimates were more accurate than BT dose estimates using 0.01 mg/kg as a dosing standard.
Adding body habitus information to the patient's length results in a more accurate weight estimate than length alone in children. The accuracy improvement is greater in children 3 years and older as compared to younger children.
基于身长的给药系统可减少与复苏药物给药相关的误差。相同身长的肥胖儿童和瘦小儿童，尽管体重不同，但给药剂量相同。
在根据体型图标对儿童进行分类后，测量其身长（身高）和体重。在每个体型组内，进行回归分析，以使用体型和身长（BHL）生成体重估计公式。将这种BHL方法与 Broselow 卷尺（BT）进行比较。
绘制身高和体重数据以获得视觉散点图。对数回归产生的相关系数高于标准线性回归。在体型组内，以0.01 mg/kg作为给药标准时，BHL肾上腺素剂量估计比BT剂量估计更准确。
在儿童中，将体型信息添加到患者的身长中，比仅使用身长能得出更准确的体重估计。与年幼儿童相比，3岁及以上儿童的准确性提高更大。
