Abstract
A validation study of the PAWPER XL tape: accurate estimation of both total and ideal body weight in children up to 16 years of age
Highlights
Obtaining an estimate of weight forms part of the emergency management of critically ill or injured children, as most drug doses, and many other interventions, are based on weight
There was a high prevalence of children (20.5%) whose total body weight (TBW) and ideal body weight (IBW) differed by more than 20%
With regards to estimating TBW, the Broselow tape and the Mercy method achieved an intermediate degree of accuracy (PW10s of 57.1 and 63.9 respectively) while the PAWPER tape and PAWPER XL tape achieved an extremely high degree of accuracy (PW10 81.8% and 83.4% respectively)
Summary
Obtaining an estimate of weight forms part of the emergency management of critically ill or injured children, as most drug doses, and many other interventions, are based on weight. The original PAWPER system failed to provide accurate weight estimations for children who were severely obese. Two studies from populations in the USA with a high prevalence of obesity showed that the PAWPER tape underestimated weight in obese children [4,5]. This could lead to dosing errors in these children. The PAWPER tape has proved to be one of the most accurate weight estimation systems available, but its reduced accuracy in obese children and relative shortness (153cm) limit its functioning. The aim of this study was to evaluate the accuracy of the PAWPER XL tape in estimating total body weight (TBW) and ideal body weight (IBW) in a population with a high prevalence of underweight and obese children
