Estimation of weight in adults from height: a novel option for a quick bedside technique

摘要: In critical care situations, there are often neither the means nor time to weigh each patient before administering strict weight-based drugs/procedures. A convenient, quick and accurate method is a priority in such circumstances for safety effectiveness emergent interventions as none exists adults while those available complex yet be validated. We aimed study correlation accuracy of bedside weight estimation using height. The technique estimated body weight—eBW(kg) = (N − 1)100, where ‘N’ measured height metres. Adult undergraduates were enrolled 10/09/2015. Their heights weights formula was used obtain weight. SPSS version 21.0, Chicago, IL, USA utilised data analysis. analysed 122 participants aged 21–38 years with height = 1.55 m–1.95 m. actual range = 48.0 kg–91.0 kg, mean = 65.3 kg ± 9.7 kg S.E. = 2.0 eBW = 55 kg–95 kg, mean = 69.1 kg ± 8.4 kg S.E. = 1.5. On BMI classes, positive predictive value 94.7% ‘normal’ category 95.5% ‘overweight’. Correlation coefficient at 99% confidence interval yielded (r) = + 1, (P = 0.000) linear regression (r2) = + 1 95% (P = 0.000). strength agreement/precision established by Bland-Altman plot 95% ± 2 s kappa statistic value = 0. 618. This unprecedented statistical characterisation two estimate measures have good agreement scientifically proposes utility our eBW(kg) = 100(N−1) ATLS protocol.
