Introduction: Placenta accreta spectrum (PAS) is a serious condition with a mortality as high as 7%. However, the factors associated with this type of death have not been adequately described, with an almost complete lack of publications analyzing the determining factors of death in this disease. The aim of our work is to describe the causes of death related to PAS and to analyze the associated diagnosis and treatment problems. Material and methods: This is an inter-continental, multicenter, descriptive, retrospective study in low-and middle-income countries. Maternal deaths related to PAS between January 2015 and December 2020 were included. Crucial points in the management of PAS, including prenatal diagnosis and details of the surgical treatment and postoperative management, were evaluated. | 1453 NIETO-CALVACHE ET AL.
Neste ensaio são apresentadas algumas reflexões relacionadas com conceitos frequentemente usados nas pesquisas chamadas qualitativas. A primeira questão que é colocada é o conceito mesmo do que é Pesquisa Qualitativa (PQ), fazendo ênfase que essa expressão faz alusão de uma variedade grande de formas de pesquisar assuntos sociais e educacionais. Após são oferecidos dez critérios para identificar variantes e invariantes entre as diversas famílias de PQ. A seguir é descrito o papel do pesquisador na Pesquisa Qualitativa, dando destaque ao Lugar Epistemológico ocupado pelo pesquisador neste tipo de pesquisa e aos compromissos cognitivos que são assumidos pelo pesquisador qualitativo. Logo, são abordados o conceito de triangulação e a Entrevista como técnica privilegiada para obter informações em Pesquisa Qualitativa. O trabalho conclui deixando em aberto a reflexão sobre os assuntos desenvolvidos no ensaio.
Palavras-chave: Variantes e Invariantes; Triangulação; Enquque Pentadimensional; Lugar Epistemológico.
