ABSTRACT

Background: Pregnancy of macrosomic fetus increases risk of several complications. Methods: Retrospective analyse of 306 deliveries occurred in HU/USP between 2002 and 2004 whose newborns had weight = 4000 gram. Results: Gestational age was between 14 and 43 years (27,4 ± 6,0 years) and 33,9% with parity > 2 deliveries. The gestational age varied from 36 to 43 weeks (40,1 ± 1,1) being 54,2% postdate gestations, and the born weight was from 4000 to 5085grames (4195,5 ± 188,9). Delivery was vaginal in 141 (46,1%) pregnants and cesarean in 165 (53,9%) pregnants. The main maternofetal problems were meconeo (4,9%),trauma in newborns (2,3%), vaginal laceration (1,9%), uterus atonia (1,6%) and bisacromial distocia (1,6%). There were not signifi cative difference on the occurrence of problems (OR=0,95; IC=0,52-1,74) between cesarean and vaginal delivery, and between newborns with weight de 4500 gram (OR=1,09; IC=0,38-3,10).

Conclusion:

Postdate, multiparity and advanced maternal age were related with macrosomia. Fetal macrosomia is also related to cesarean,delivery trauma and perinatal morbity, however, it is not show the correlation in delivery way or birthweight < or > of 4500gram and the frequency of maternofetal problems.
