MATERNAL RISK FACTORS ASSOCIATED WITH PREMATURE RUPTURE OF MEMBRANES

Abstract

Introduction: Premature rupture of the membranes is defined as the rupture of the fetal membranes 12 to 18 hours or more before the onset of labor. Objective: The main objective of this literature review is to generate knowledge about the maternal risk factors associated with premature rupture of membranes. Materials and methods: It is a descriptive study of literature search and has been carried out in Pubmed, Medline, Scielo, libraries of national and international universities. Results: The risk factors found are at the age of less than 20 and older than 35 years (OR: 2.2), rural origin (OR: 5.8), stable union (OR: 2,600), pregnant woman poorly nourished (OR: 4,200), obesity with (OR: 3), history of abortion (OR: 2.76), multiple gestation (OR: 4.5), primitive (OR: 3.370), large multiparous (OR: 2.10), short intergenic period (OR : 4,128), previous RPM (OR: 4,265), IUD use (OR: 3,151), sexual act before RPM (OR: 3,182), Hb 9,9-7,1 grs / dl (OR: 2), metrorrhagia 1st and 2nd trimester (OR: 3.88), cervical-vaginal infection (OR: 13), urinary infection (OR: 2.56). Conclusions: The main maternal risk factors that condition premature rupture of membranes, we have: Age under 20 and over 35 years of age, rural origin, stable union, malnourished pregnant woman, pregnant woman with obesity, history of abortion, multiple pregnancy, primitive, large multiparous, short intergenic period, prior RPM, IUD use, sexual intercourse before RPM, Hb 9.9-7.1 grs / dl, 1st and 2nd trimester metrorrhagia, cervical-vaginal infection, urinary tract infection.
