Assessment of the Fetal Weight: Application of Johanso’s Formula Versus Help of Ultrasonography.
AbstractPerinatal mortality rate is 95.1 /1000 live births in Pakistan which is much higher when compared to the developed countries (United Kingdom 35, Japan 19) and still high in comparison to the developing countries (India 48.6, Burma 57.2, Indonesia 45 and Thailand 28.3). this perinatal mortality in addition to many other factors is closely related to the weight of the fetus , below or above normal . Average normal birth weight is 2.5-4.5 kg. Birth weight between 1.5-2.5 kg is low birth weight, between 1.0-1.5 kg is very low birth weight and below 1.5 kg ¡t is declared extremely low birth weight. If the weight of the delivered conceptus is below 0.5 kg it is known as abortion/ miscarriage. My study is focused on assessing the weight of the baby for which I have applied Johnson’s formula and compared with ultrasonographic assessment later confirmed by weighing fetus after delivery. In addition gestation age, mode of the delivery, presence of any risk factor, and fetal out come in perinatal period were noted.
