Prevalencia de factores de riesgo asociados a placenta previa en gestantes del Hospital Alfredo G. Paulson durante el período enero 2018 - diciembre 2019.

Abstract

Introduction: Placenta previa is defined as the placental implantation in the lower uterine segment that is located over the internal cervical os. Clinically it can present with painless vaginal bleeding, usually in the third trimester of pregnancy. Objective: To determine the prevalence of risk factors associated with placenta previa in pregnant patients at the Alfredo G. Paulson Hospital during the period January 2018-December 2019. Materials and Methods: Prevalence or Cross-Sectional Study (observational, descriptive and analytical). The documentation technique will be applied, through the review of medical records and operative reports registered in the database of the Alfredo G. Paulson Hospital. Results: The final sample consisted of 75 patients with a diagnosis of placenta previa. 81.3% of them were multiparous and 18.7% were primiparous. When evaluating the frequency of previous births, it was observed that 69.3% had zero, 14.7% had a previous birth and the rest of the patients had between two to five previous births. Conclusion: The studied sample presented a 4: 1 multiparity index, with a previous uterine scar in half of the studied patients. The degree of placenta previa most frequently found was total occlusive in 57% of the patients, and placental accretism was found in 13%.
