AbstractWe evaluated acute neonatal morbidities in the delivery room associated with primary cesarean performed prior to labor and in the first or second stages of labor. A retrospective cohort study was conducted on subjects undergoing term, primary cesareans at the Women's Pavilion, Miller Children's Hospital in Long Beach, California from 2000 to 2007. Acute neonatal morbidities were tabulated as a function of time during labor when cesarean was performed. Composite neonatal morbidity was defined as the presence of at least one of the following: low 5-minute Apgar score, need for intubation, and/or admission to neonatal intensive care unit. One thousand forty-five subjects delivered by cesarean without labor, 3098 in first stage, and 951 in second stage. Five-minute Apgar score < 7 was more common in cesareans performed during second stage than during first stage or without labor [3/1045 (0.3%) versus 28/3098 (0.9%) versus 12/951 (1.3%), P = 0.039]. Composite neonatal morbidity was not significantly different among the stages. Acute neonatal morbidities were not affected by the presence or absence of labor. Potential long-term sequelae require further study.Thieme Medical Publishers.
