“…[7][8][9][10][11][12] In light of the high obesity rates, recent studies on the BT have questioned whether this method still accurately estimates the weight of children. [13][14][15][16] As the BT has not been revalidated in light of the childhood obesity epidemic, we studied a representative cohort to address the question of whether the BT accurately estimates the weight of children in Ontario, the most populous province of Canada.…”

Objective: The Broselow Pediatric Emergency Tape (Armstrong Medical Industries, Inc., Lincolnshire, IL) (BT) is a wellestablished 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. Methods: 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. Results: 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 5 0.95577, p , 0.0001), the BT underestimated the actual weight by 1.62 kg (7.1% 6 16.9% SD, 95% CI 226.0-40.2). The BT had an $ 10% PE 43.7% of the time. Conclusions: 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.

Acute life-threatening events involving children in the radiology department are rare. Nonetheless, radiologists should be competent in the relatively simple procedures required to maintain or restore vital functions in paediatric patients, particularly if their practice involves seriously ill or sedated children. This article gives a practical overview of the immediate management of paediatric emergencies that the radiologist is likely to encounter, using a structured (ABCD) approach. Emphasis is given to the early recognition of respiratory embarrassment and shock, and early intervention to prevent deterioration towards circulatory arrest. The management of cardiorespiratory arrest, anaphylaxis and convulsions in children is also addressed.

“…A variety of methods have therefore been developed over the years to rapidly estimate a child's weight. [5][6][7] The Accuracy of the Broselow ™ Pediatric Emergency Tape The Broselow ™ Pediatric Emergency Tape (BT) was developed in the late 1970s as a tool to determine a child's weight based on height calculated by measuring the head-to-heel body length while the patient is in a supine position. 8,9 Subsequently, the tool sorts children into weight categories based on their length, with each category assigned a colour that corresponds to a list of proportionally-sized equipment, appropriate doses of emergency drugs and safe levels of defibrillation energy.…”

abstract:Objectives: This study aimed to evaluate the accuracy of the Broselow ™ Pediatric Emergency Tape (BT) for estimating weight in an Omani paediatric population at a tertiary care hospital. Methods: This retrospective cross-sectional study was conducted during July 2015. The electronic medical records of Omani outpatients <14 years old attending the Sultan Qaboos University Hospital, Muscat, Oman, between July 2009 and June 2013 were reviewed for recorded height and weight data. The BT Version 2002A was used to predict weight based on actual height measurements. Predicted weight measurements were then compared with actual weight to determine the accuracy of the estimation. Results: A total of 3,339 children were included in the study, of which 43.5% were female and 56.5% were male. The mean age was 6.4 ± 3.1 years and the mean height was 93.2 ± 23.5 cm. The mean actual weight was 13.9 ± 6.7 kg while the mean BT-predicted weight was 14.4 ± 6.9 kg. The BT-predicted weight estimations correlated significantly with actual weight measurements (intraclass correlation coefficient: 0.97; P <0.001). A Bland-Altman analysis indicated that the BT performed well when estimating weight among Omani children, with an overestimation of only 0.5 kg for the entire cohort. Conclusion: The BT was found to be an effective tool for estimating weight according to body length in an Omani paediatric population. It should therefore be considered for use in emergency situations when actual weight cannot be determined.
