Mode of delivery and birth outcomes of macrosomic infants.
This review examines and summarises the literature regarding the mode of delivery of macrosomic infants and subsequent perinatal outcomes. A search of electronic databases was conducted and supplemented with investigation of the references cited in the original articles. Although the rates of obstetric complications differ among high birth weight infants delivered by caesarean section compared to those delivered vaginally, there is currently little evidence that perinatal mortality differs significantly by delivery method. Shoulder dystocia and birth injury occur with greater frequency among macrosomic infants, yet the relative inaccuracy of clinical and ultrasonographic estimates of birth weight among high birth weight infants indicates that a trial of labour may be warranted among non-diabetic mothers with a suspected macrosomic fetus. The majority of studies identified in this review utilised small sample sizes and observational design, thereby hindering valid assessments of the impact of delivery method on the mortality of this population. Consequently, an optimal management strategy has yet to be defined.
