![]() The categorical data were expressed as n (%) and analyzed using the chi-square test. All continuous data conformed to the normal distribution (according to the Kolmogorov-Smirnov test) they were expressed as means ± standard deviation (SD) and were analyzed using ANOVA. SPSS 23.0 (IBM, Armonk, NY, USA) and MedCalc 17.2 software (MedCalc Software bvba, Ostend, Belgium) were used for statistical analysis. Body mass index (BMI) was calculated: weight (kg)/. The same nurse measured the children's height and weight. was used for infants 19-kg, which corresponds to the color zones of the Broselow tape (gray, pink and red vs. The standard calibrated model 376 infants scale produced by SECA Medical Measurement System (Hangzhou) Co., Ltd. The actual weight of the children was measured using the RGZ-12-RT children's scale produced by Wuxi Weigher Factory Co., Ltd. Written informed consent was obtained from the children > 8 years old or their legal guardians. This study was approved by the ethics of the Children's Hospital of Zhejiang University School of Medicine (#2022-IRB-029). All subjects who met the inclusion and exclusion criteria were consecutively included. specific conditions like amputation, cerebral palsy, microcephaly, dehydration, edema, growth hormone deficiency, severe joint contracture, or nerve defect that might seriously affect their weight and/or height. serious conditions preventing the actual weight from being measured, such as shock, severe trauma, respiratory arrest or circulatory failure or C. children's height 143 cm and weight 36 kg B. The inclusion criteria were children from newborn to 12 years old and voluntarily participating in the study. The hospital admits children from Zhejiang province and surrounding provinces. Therefore, this study aimed to evaluate the validity of the Broselow tape in estimating the weight of Chinese children.Ī cross-sectional was conducted in the emergency department of the Children's Hospital of Zhejiang University School of Medicine (Hangzhou, Zhejiang Province, China) in March 2022. The data that was used to design the Broselow tape was based on the National Center for Health Statistics (NCHS) and the national experimental survey on health and nutrition (NHANES) ( 4), which does not include data of Chinese children. Still, the most important issue with weight estimation methods is that these methods display insufficient accuracy and consistency among the different populations ( 7). ![]() It is recognized as the standard of emergency treatment for children in most Western medical textbooks and publications and is recommended by advanced pediatric life support (APLS) ( 5, 6). Moreover, the Broselow tape provides medical instructions, including drug dose, equipment model and voltage level during defibrillation. The tape ruler is divided into nine colors and is suitable for children weighing 3 to 36 kg and measuring 47 to 143 cm. The Broselow tape is a tape measure based on color-coding with length. Among them, the Broselow tape method has the longest history and the highest accuracy, and is the most widely used ( 4). ![]() There are also precalculated estimation systems, such as the Broselow tape, advanced pediatric life support (APLS) method, devised weight estimation method (DWEM) method, Oakley table, Traub-Johnson method and Traub-Kichen method. Two-dimensional methods can be more precise ( 4). One-dimensional methods usually fail because they do not consider the variability in weight-for-age and weight-for-length and pediatric obesity ( 3). Currently, the most frequently used methods for estimating the weight of pediatric emergency patients include parents or medical staff estimation, age-based formula, and length-based method ( 2). Hence, a rapid estimation of the children's weights is very essential to ensure the safety and accuracy of the treatments ( 1). In pediatric emergency wards, there are often critical children with shock, severe trauma, respiratory arrest or circulatory failure who need immediate treatment or management, but it can be very difficult to obtain an accurate weight value, and an inaccurate weight estimation is likely to lead to wrong dosage, which will lead to serious consequences, and it is also one of the most common errors of improper medication in emergency wards. required for diagnosis and treatment of children are commonly calculated/evaluated based on weight. Compared with adults, the dosage, infusion volume, equipment, etc.
