Resultados perinatales en gestaciones triples. Estudio de 90 casos

Abstract

Objectives To analyze the perinatal results of 90 triplet pregnancies attended in the Hospital de Cruces (Vizcaya) during the last 15 years. Material and methods From January 1989 until December 2003 there were a total of 78 566 deliveries, of which 90 were triplets. We make a retrospective study of these pregnancies. Results The incidence of triplet pregnancies has increased noticeably in recent years, increasing from 0.5 ‰ in 1989 to 3 ‰ in 2002. The main complication of these pregnancies was pre-term labour (45.6%), with an average hospital admission of 12.4 ± 13.9 days (range 1-60 days). Mean gestational age at delivery was 34 ± 2.9 weeks, with a pre-maturity level of 86.6%. The average weight of the newborns was 1795 ± 506, 1890 ± 513 and 1795 ± 517 grams respectively for the first, second and third fetus. Of the newborns, 6.28% weighed less than 1000 grams. All cases of perinatal mortality (18.5%) were in this group of newborns who weighed less than 1000 grams. Conclusion The level of pre-maturity is the main complication to remember when making any prognostic on triplet pregnancies, and is the main influence for perinatal results.
