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

Objective: There is limited data on fetal cranial dimensions of Nigerian population. This is important because the study of normal and abnormal growth of children has become an increasingly important part of the practice and research in all fields related to child health; more so that prenatal and postnatal growth is one continuous process. Material & Methods:In a cross-sectional study conducted on 13,740 Nigerian fetuses ranging from 12 weeks to 42 weeks at the Centre for Reproductive Health Research Jos; biparietal diameter and occipitofrontal diameter were measured using ultrasound machine in order to calculate fetal cephalic index. The values were statistically analyzed after deriving the relevant indices. Results:The regression equation was calculated between gestational age and cephalic index of fetuses of Nigerian women. This equation y = 1.3x + 59.88; showed a linear relationship which was stronger from 12 to 16 weeks of gestation. Above 16 weeks gestation, the relationship was found to be quite weak. Coefficient of correlation is r2 = 0.9844 (p < 0.0001). Conclusion:The fetal skulls were found to be mesocephalic in the early weeks and brachycephalic at term.

Objective: Fundal height measurements in centimeters have always been an objective method of evaluating fetal growth in pregnancy. The accepted Mcdonald's rule refers primarily to Caucasians regrettably. Since fundal height may actually vary in an anthropological sense it was considered necessary to apply Mcdonald's rule to African subjects to see whether there is any significant difference. The aim of this study is to construct symphysio-fundal height nomogram for normal pregnant Nigerian women. Material & Methods:In a cross sectional mode, four hundred and five pregnant Nigerian women were studied to examine how their fundal height values compared with those in the literature. A regression equation was derived for the 10th and 90th centiles. Values outside the range of 10 -90th centiles are to be used for the prediction of small-for-dates and large-for-dates babies respectively. The prediction formulae for the various centiles derived from regression analysis and their usefulness in clinical anthropological practice using fundal height measurement are highlighted. Results:The study demonstrated a significant difference in fundal height values of Nigerian women especially in late pregnancy compared with other published values in the literature. A positive linear correlation between symphysio-fundal height and fetal gestational age was found in Nigerians with a correlation coefficient of R2 = 0.9962 (p<0.001). The relationship is best described by the second order polynomial regression equation y = -0.0024x2 + 1.1255x -1.8334 where y is the symphysio-fundal height in centimeters while x is the gestational age in weeks. Conclusion:Symphysio-fundal height chart is a valuable tool for assessing fetal growth in the antenatal clinic in as much as it is cautiously constructed for a given population and the same method of measurement is strictly adhered to by different observers in the same organization.
