	abstract = {OBJECTIVES: To gather data on the ages and weights of paediatric patients between 1 and 10 years of age, and to compare these data with the current weight estimation formula weight(kg) = 2(age+4). If a significant difference was found, the data would be used to derive a more accurate formula. DESIGN: Retrospective study using data collected from paediatric attendances at an emergency department (ED). SETTING: A large ED in a major UK city, treating both children and adults. Patients: 17 244 children aged 1-10 years, attending the ED between June and December 2005. MAIN OUTCOME MEASURES: Weight difference between the measured weight and the expected weight, the latter given by weight = 2(age+4). RESULTS: The weights of seriously ill children were recorded in only 41.5\% of cases, necessitating a weight estimate in the remainder. The formula weight = 2(age+4) underestimated children's weights by a mean of 18.8\% (95\% confidence interval (95\% CI) 18.42\% to 19.18\%). Using linear regression and analysis of each individual age group, ten new formulas were tested. Of these formulas, weight(kg) = 3(age)+7 proved the most accurate with a mean underestimate of just 2.48\% (95\% CI 2.17\% to 2.79\%). CONCLUSIONS: Weight estimation remains of paramount importance in paediatric resuscitation. This study shows that the current estimation formula provides a significant underestimate of children's weights. When used to calculate drug and fluid dosages, this may lead to the under-resuscitation of a critically ill child. The formula weight(kg) = 3(age)+7 provided a safe and more accurate estimate of the weight of today's child.},
