Conclusion
Prognostical favorable factors for natural delivery of macrosomic fetus are: delivery in history, the gestation period not more than 39 weeks, the symmetric form of macrosomia, no more than first degree ACO, stable glycemia value during the pregnancy (<5.6 mmol/l) [4].
The ratio of the fetus head size to the biacromial diameter mainly contributes to the development of shoulder dystocia. This ratio may be a criterion for the indication of natural delivery of macrosomic fetus. Thus, the prediction of shoulder dystocia and rational management strategies for macrosomia help to avoids perinatal deaths and significantly reduce birth injuries.
