RESUMO
The aim of this study was to describe the fetal and maternal outcomes of triplet gestation and to report on the maternal characteristics of those pregnancies in a tertiary care centre in Oman. A retrospective study was undertaken of all triplet pregnancies delivered at Sultan Qaboos University Hospital, Muscat, Oman, between January 2009 and December 2011. Over the three-year study period, there were 9,140 deliveries. Of these, there were 18 triplet pregnancies, giving a frequency of 0.2%. The mean gestational age at delivery was 31.0 +/- 3.0 weeks, and the mean birth weight was 1.594 +/- 460 g. The most common maternal complications were preterm labour in 13 pregnancies [72.2%], gestational diabetes in 7 [39%] and gestational hypertension in 5 [28%]. Of the total deliveries, there were 54 neonates. Neonatal complications among these included hyaline membrane disease in 25 neonates [46%], hyperbilirubinaemia in 24 [43%], sepsis in 18 [33%] and anaemia in 8 [15%]. The perinatal mortality rate was 55 per 1.000 births. The maternal and neonatal outcomes of triplet pregnancies were similar to those reported in other studies
