Factors associated with birth asphyxia in Fang Hospital

Abstract

Objective :  To study Factors associated with birth asphyxia and Analysis result seeks the variable that has the relation was birth asphyxia.

method : The study design of  retrospective case control study . The 450 women who delivery between 1 January to 31 December 2012 were randomized by consecutive selection. Case were 135 women who delivery newborn with 1-minute APGAR score of 7 or less. Control were 270 women who delivery newborn with 1-minute APGAR score more than 7. The risk factor for birth asphyxia were determined.  

Results : The most associated risk  factors significantly associated with birth asphyxia included pregnancy induced hypertension  (OR = 5.85 , 95%CI = 1.87- 9.93 ) , vacuum or forceps extraction (OR = 5.47 , 95%CI = 1.93 - 13.59 ) ,  cesarean section (OR = 4.43 , 95%CI = 2.64-7.41 ) , breech presentation (OR = 4.13 , 95%CI = 2.64- 4.48 ) , moderate to thick meconium (OR = 3.26 , 95%CI = 2.64-4.07 ) ,education 6^th grade (OR = 2.98 , 95% CI = 2.39-3.72 )  , birth weight less than 2,500 grams (OR = 2.53 , 95% CI = 1.88-3.11 )   chorioamnionitis (OR = 2.44 , 95% CI = 1.54-3.87 )  , gestational age less than 37  weeks (OR = 2.25 , 95% CI = 1.19-3.78 )  and refer (OR = 0.84 ,95% CI = 0.62-0.97 . Analyze seek the algebraic equation predicts occurrence condition with birth asphyxia , from the analysis result seeks the variable that has the relation was  logit (birth asphyxia) = -6.92+2.72(chronic hypertension) +1.41 (vacuum or forceps extraction + 1.98 (cesarean section) + 1.45 (breech presentation) + 1.23 (Moderate to thick meconium) + 1.76 ( education 6^th grade) +0.92 (birth weight less than 2,500 grams) + 0.56 (chorioamnionitis) + 1.12 (gestational age less than 37  weeks) + 0.25 (refer)

Conclusion : Risk factors of birth asphyxia could be protected. The early diagnosis and proper management will decrease birth asphyxia during delivery.
