Abstract

OBJECTIVE
To determine obstetric outcome in infants > or =4,500 g according to delivery mode.
METHODS
Records of 271 mothers and infants weighing > or =4,500 g over a 11-year period (1993~2003) were retrospectively reviewed. Maternal and perinatal outcomes were compared in relation to delivery mode.
RESULTS
The frequency of macrosomia ranged 0.38% in 4,500 g or more. Vaginal delivery was achievable in 78/271 (28.8%) of women allowed to labor, of which 71.2% were operative. In macrosomia frequency correlations to parity showed 33.9% (92 cases) in primiparous women, 66.9% (179 cases) in multiparous women. According to the type of delivery, cesarean section has proven to be the most popular mode. The cesarean section group had a higher incidence of maternal BMI (> 25 kg/m2). The frequency of diabetes, hypertension, low Apgar score at 5 and 10 minutes was similar in both groups.
CONCLUSION
It would be appropriate to have definite diagnostic schemes and adequate choice of delivery method for macrosomia. Maternal height, weight, BMI (body mass index) may associated with fetal body weight and delivery mode.
