Drug dosages used during pediatric emergencies and resuscitation are often based on estimated body weight. The Broselow Tape, a tape measure that estimates weight and drug dosages for pediatric patients from their length, has been developed to facilitate proper dosing during emergencies. In our study, 937 children of known weight were measured with this tape. Weight estimates generated by the tape were found to be within 15% error for 79% of the children. The tape was found to be extremely accurate for children from 3.5 to 10 kg, and from 10 to 25 kg. Regression lines of estimated compared with actual weight for these children have slopes of 0.98 and 0.96, respectively, not significantly different from the ideal slope of 1.00 (P = 28 and .13). Accuracy was significantly decreased for measured children who weighed more than 25 kg. In a separate group of children (n = 53), the tape was shown to be more accurate than weight estimates made by residents and pediatric nurses (P less than .0001). Use of the Broselow Tape is a simple, accurate method of estimating pediatric weights and drug doses and eliminates the need for memorization and calculation.
儿科急诊和复苏期间使用的药物剂量通常基于估计的体重。Broselow卷尺是一种根据小儿患者的身长来估计体重和药物剂量的卷尺，其开发目的是在紧急情况下便于正确给药。在我们的研究中，使用这种卷尺对937名已知体重的儿童进行了测量。结果发现，对于79%的儿童，该卷尺产生的体重估计误差在15%以内。对于体重在3.5至10千克以及10至25千克的儿童，该卷尺被发现极其准确。这些儿童估计体重与实际体重的回归线斜率分别为0.98和0.96，与理想斜率1.00无显著差异（P值分别为0.28和0.13）。对于体重超过25千克的被测儿童，准确性显著下降。在另一组儿童（n = 53）中，该卷尺被证明比住院医生和儿科护士所做的体重估计更准确（P值小于0.0001）。使用Broselow卷尺是一种简单、准确的估计小儿体重和药物剂量的方法，无需记忆和计算。
