The Broselow Pediatric Emergency Tape (Armstrong Medical Industries, Inc., Lincolnshire, IL) (BT) is a well-established length-based tool for estimation of body weight for children during resuscitation. In view of pandemic childhood obesity, the BT may no longer accurately estimate weight. We therefore studied the BT in children from Ontario in a large recent patient cohort.
Actual height and weight were obtained from an urban and a rural setting. Children were prospectively recruited between April 2007 and July 2008 from the emergency department and outpatient clinics at the London Health Science Centre. Rural children from junior kindergarten to grade 4 were also recruited in the spring of 2008 from the Avon Maitland District School Board. Data for preschool children were obtained from three daycare centres and the electronic medical record from the Maitland Valley Medical Centre. The predicted weight from the BT was compared to the actual weight using Spearman rank correlation; agreement and percent error (PE) were also calculated.
A total of 6,361 children (46.2% female) were included in the study. The median age was 3.9 years (interquartile range [IQR] 1.56-7.67 years), weight was 17.2 kg (IQR 11.6-25.4 kg), and height was 103.5 cm (IQR 82-124.4 cm). Although the BT weight estimate correlated with the actual weight (r = 0.95577, p < 0.0001), the BT underestimated the actual weight by 1.62 kg (7.1% ± 16.9% SD, 95% CI -26.0-40.2). The BT had an ≥ 10% PE 43.7% of the time.
Although the BT remains an effective method for estimating pediatric weight, it was not accurate and tended to underestimate the weight of Ontario children. Until more accurate measurement tools for emergency departments are developed, physicians should be aware of this discrepancy.
Broselow 儿科急救带（Armstrong Medical Industries，Inc.，Lincolnshire，IL）（BT）是一种经过验证的基于长度的工具，可用于在复苏期间估算儿童的体重。鉴于大流行期间儿童肥胖的情况，BT 可能不再能准确估计体重。因此，我们在安大略省的一个大型近期患者队列中对 BT 进行了研究。
实际身高和体重来自城市和农村地区。2007 年 4 月至 2008 年 7 月，从伦敦健康科学中心的急诊科和门诊诊所前瞻性招募儿童。2008 年春季，还从安大略省阿冯·梅特兰区学校董事会招募了小学幼儿园到 4 年级的农村儿童。来自三个日托中心的学龄前儿童的数据和米德尔顿谷医疗中心的电子病历。使用 Spearman 秩相关比较 BT 预测体重与实际体重；还计算了一致性和百分比误差（PE）。
共有 6361 名儿童（46.2%为女性）纳入研究。中位年龄为 3.9 岁（四分位间距 [IQR] 1.56-7.67 岁），体重为 17.2kg（IQR 11.6-25.4kg），身高为 103.5cm（IQR 82-124.4cm）。尽管 BT 体重估计与实际体重相关（r=0.95577，p<0.0001），但 BT 低估了实际体重 1.62kg（7.1%±16.9%SD，95%CI-26.0-40.2）。BT 的 PE≥10%的情况占 43.7%。
尽管 BT 仍然是一种有效的儿童体重估计方法，但它并不准确，而且往往低估了安大略省儿童的体重。在开发出更准确的急诊测量工具之前，医生应该意识到这一差异。
