Abstract
Objective: Recognize the complications in twin pregnancies and relate them to the maternal-fetal consequences. Methods: This is an integrative review based on the reading of articles found in the Scientific Electronic Library Online, Literatura Latino-Americana do Caribe em Ciências da Saúde, Turning Research Into Practice and Google Scholar databases, which includes the productions of the last five years. The search was carried out with the following health descriptors: “Twin Pregnancy and Complications”, “Pregnancy of twins and complications” and “Pregnancy Complications and Twinning”. The selection of articles was done in three stages, with the application of filters, reading the title and summary and reading the articles. Results: 20 articles were selected and two categories of complications were identified, maternal and fetal. As for maternal complications, there was a prevalence of premature birth, premature rupture of the membranes, hypertensive disorders, eclampsia and pre-eclampsia, and for the fetal ones, hospitalization, fetal death and low weight. Final considerations: The analysis of the articles found allowed us to conclude that there is a higher prevalence of maternal and fetal complications in twin pregnancies compared to single pregnancies. Although they are didactically separated into categories, most complications are related, with some associations between cause and consequence.
