Background and purpose: Âccurate estimation of fetal weight is of paramount importance in the management of labor and delivery and may be related to critical points of decision making and proper management. This study was done in order to compare the accuracy of clinical and ultrasonic estimation of fetal weight in Ïmam Khomeini hospital of Sari, Ïran.
Materials and methods: During this study(March 2000- December 2004) 174 pregnant women met the inclusion criteria. Written consent was obtaind from the patients and fetal weight was estimated by clinical examination and johnson’s formula at their admission by one physicians. Then they were transfered to the ultrasound ward and ËFW was estimated by one sonologist. Finally, all newborns, weight was measured by one scale. Statistical analysis was done by frequency, Diagram, paired sample T Test.
Results: The mean of the age of subjects was 24.95± 4.59 years and their mean weight was 72.07+1104 kg and the mean of their gestational age was 38 weeks± 5days. paired T test showed that there is no significant differences between estimated fetal weight by ultrasound and actual birth weight Ïn SGÂ and LGÂ group ËFW by this method had a significant difference with actual birth weight (P<0.001). Ïn ÂGÂ group birth weight had no any significant difference with actual Birth weight.
Çonclusion: Âccuracy of weight estimation using the clinical examination and ultrasound was found to be low in SGÂ and LGÂ groups. Ïn LGÂ groups Johnson’s formula was more accurate than others. However, a systematic review with methaanalysis was recommended.
