(17) Most of the stillbirth and neonatal deaths were because of gross asphyxia, prolonged labor due to cephalopelvic disproportion and uterine dysfunction, fetal distress, and abnormal presentation.
(18) Each case was complicated by neonatal asphyxia, and the neonate needed resuscitation by means of endotracheal intubation.
(19) Low birthweight (LBW) and perinatal asphyxia are known to be high-risk factors for a number of neurodevelopmental deficits.
(20) On these conditions multiple anomalies combined with prematurity and intrauterine asphyxia had some influence on, whether a patient lived so long, that an operation could take place.
Oxygen
Definition:
(n.) A colorless, tasteless, odorless, gaseous element occurring in the free state in the atmosphere, of which it forms about 23 per cent by weight and about 21 per cent by volume, being slightly heavier than nitrogen. Symbol O. Atomic weight 15.96.
(n.) Chlorine used in bleaching.
Example Sentences:
