Mortality and immediate morbidity in term babies with low Apgar scores (Zimbabwe).

A retrospective study was undertaken to document immediate morbidity and mortality associated with low Apgar scores (5 or less) at 5 min in singleton term babies (37 weeks or more). From October 1986 to February 1987, 84 term babies had low Apgar scores, giving an incidence of 15/1000 live births. Overall mortality in these patients was 42%, and in those in whom Apgar scores remained 0-3 at 5 min, mortality was 77%. Evidence of severe-to-moderate hypoxic-ischaemic encephalopathy was noted in 44 (52%) and 17 (20%) failed to establish spontaneous respiration within the 1st few hours of life. Meconium aspiration syndrome was diagnosed in 29 (35%). A control group of 141 term babies with 5-min Apgar scores of 7 or more were identified and the presence of possible risk factors associated with low Apgar scores was assessed. Primiparity and prolonged second stages of labour in all parities were found to be significantly associated with low Apgar scores. Improved obstetric care and appropriate management of the newborn at delivery and in the neonatal period may help to reduce mortality and morbidity in some term babies.
