“…24 Similarly, Ugwa EA et al, found that correlation between clinical estimation and actual birth weight was weak and also found significant error in estimating fetal weight by ultrasound and opined that it could lead to unnecessary obstetrical intervention. 25 The observations implied that there was clearly a role for clinical estimation of birth weight as a diagnostic tool, suggesting that clinical estimation was sufficient to manage labour and delivery in a term pregnancy especially in resource poor settings as well as for early detection of fetal weight abnormalities and the proper management of pregnancy.…”

Background: Accurate estimation of fetal weight is of paramount importance in the management of labour and childbirth. In developing countries including India, estimation of fetal weight by clinical method is important as ultrasound is not available in all health care settings. In view of this, the present study was conducted to estimate the fetal weight assessed by clinical and ultrasound method and correlating with the birth weight.Methods: A cross-sectional study was conducted to estimate fetal weight clinically by using Johnson’s formula and sonographically based on Hadlock’s formula in the Department of Obstetrics and Gynecology in collaboration with Department of Radiodiagnosis, Regional Institute of Medical Sciences, Imphal from October 2016 to March 2018. The study consisted of 525 pregnant women between 37 to 40 weeks of gestation in whom delivery was anticipated within one week of fetal weight estimation by clinical and ultrasound method and correlating it with the baby’s birth weight measured immediately after delivery. Analysis was done using Chi-square and Student’s t-test and p-value of <0.05 was taken as significant.Results: Both methods showed positive correlation with birth weight but clinical method (r=0.925) had stronger correlation compared with ultrasound method (r=0.508).Conclusions: Fetal weight estimation using Johnson’s formula had stronger correlation with the birth weight than ultrasound method and hence, useful for developing countries and all health care workers may be sensitized about the method.

“…Hence, estimating foetal weight has become a universal and routine antenatal care practice in modern obstetric care. 3,6 The main methods used for estimating foetal weight in current obstetric practice are imaging (ultrasonography and magnetic resonance imaging) and clinical techniques (abdominal palpation or Leopold's manoeuvre, risk factors assessed clinically, maternal self-estimated foetal weight and the application of equations that predict birth weights). 1,3,4,5,6 Obstetric ultrasonography is considered the gold standard in foetal weight estimations, but it is still not readily affordable and available, especially in low resource areas.…”

Background: The antepartum estimation of foetal weight is a major determinant of the route of delivery and this has become vital in modern day obstetrics. The limitations to the use of obstetric ultrasonography, considered as the gold standard in estimating foetal weight, make clinical estimation methods attractive alternatives, especially in resource- constrained settings where many un-booked women may report for delivery.Aim: To determine the reliability of intrapartum clinical foetal weight estimation in predicting the actual birth weight (ABW) and route of delivery among term parturient.Setting: The study was conducted at the Sacred Heart Hospital, Lantoro, a voluntary mission agency hospital in Southwest Nigeria.Methods: This cross-sectional study was conducted among 291 term parturient recruited by systematic random sampling between June and September 2017. The clinical estimation of foetal weight was carried out using Johnson’s formula.Results: The accuracy of Johnson’s formula to predict the ABW was 59.5%; while for the mode of delivery, it was 130 (75.1%) for spontaneous vaginal delivery (SVD) and 43 (24.9%) for caesarean section (CS). The sensitivity of the accuracy of Johnson’s formula to predict the mode of delivery was 75.1%, with a specificity of 35.6%, a positive predictive value (PPV) of 63.1%, and a negative predictive value (NPV) of 49.4%.Conclusion: The intrapartum clinical foetal weight estimation at term determined by Johnson’s formula was reliably predictive of ABW and SVD, but it was unreliable in predicting the need for a CS.

“…[18][19][20] While reviewing clinical methods of foetal weight estimation, Ugwa concluded that though Dare's formula is a subjective method associated with notable predictive errors, in Nigeria it is the method still used in recent studies. 21 Though Dare's method is limited to only singleton pregnancy, its advantage in the absence of facilities for USG cannot be ignored. In order to promote clinical based prediction of fetal weight, intensive training of the midwives and health staff at various health care facilities assumes significance.…”

Background: Prediction of fetal weight is one of the methods towards effective management of pregnancy and delivery. Ultrasonography is the standard method to monitor the weight, but in the absence of such facility it becomes difficult particularly in the primary care setting. Clinical methods can be considered as an option and this requires selection of the valid method in deriving the fetal weight. In the present study, an effort is made to compare two different clinical methods and USG and relate to the actual weight of the baby at birth.Methods: One hundred pregnant women satisfying the criteria, consenting for the study were recruited. Both USG and clinical methods were done and estimated the fetal weight. Weight of the baby at birth was measured.Results: All the three methods had significant relationship with the baby weight. Results indicated that estimation of fetal weight by Dare’s formula could predict 69% of the cases correctly followed by Johnson’s method which could predict 61% of the cases correctly. USG predicted 67% of the cases correctly. Percentage error was least with USG and the standard deviation of error was lower with Dare’s formula.Conclusions: It can be concluded that Dare’s formula of clinical methods can be a potential option to be promoted in predicting the fetal weight in the absence of USG facilities. Training in this method is very important and can be an integral part in managing pregnancy during delivery in primary care setting.
