Evaluation of utilization of antenatal services by mothers of babies with severe birth asphyxia

Objective:To evaluate the utilization of antenatal services by mothers of babies delivered with severe birth asphyxia at the University of Port Harcourt Teaching Hospital(UPTH) Port Harcourt,Nigeria.Methods: A case control study of the utilization of antenatal services by 97 mothers of newborns with severe birth asphyxia delivered at UPTH from 1st February to 31st October 2009 compared with mothers of newborns with normal Apgar scores was done.Relevant pregnancy,birth,family and social history was obtained by personal interviews and referral to case notes.Results: Significantly more of the mothers of babies with normal Apgar score booked early(4 months or less) and had up to 8 or more antenatal visits prior to delivery than mothers of asphyxiated babies 86(88.6%) vs 68(70.2%),P=0.002;93(95.7%) vs 68(70.2%),P=0.001 respectively.Significantly more subjects 56(57.7%) than the controls 45(46.4%) were primiparous,P= 0.04.Also,significantly more subjects 19(19.5%) suffered delay prior to intervention in labour than the controls 5(5.1%),P=0.004.Conclusion: Primiparity,delayed booking,inadequate antenatal visits and late intervention in labour have been identified as significant contributors to severe birth asphyxia.
