Diagnosis of meconium aspiration by spectrophotometric analysis of urine
Archives of Disease in Childhood
|January 1, 1978
Abstract:
The first urine passed by a newborn infant who has inhaled meconium or meconium-stained amniotic fluid often contains a dark-coloured water-soluble substance, recognisable spectrophotometrically by an absorption band at about 405 nm. Spectrophotometric analysis of the first urine can in this way be used to diagnose preceding meconium aspiration.
