OBJECTIVE: Search Histologic Chorioamnionitis frequency in patients in week 28 (+/-) and pregnancy with premature rupture of membranes. PATIENTS AND METHOD: Retrospective and observational study in which we studied all patients who came between June 28, 2011 and November 15, 2011 to receive obstetric care in the service of Tocochirurgical of the University Hospital of Saltillo, with greater than or equal 28 weeks of pregnancy. RESULTS: 598 patients were studied, and the frequency of premature rupture of membranes with histologic chorioamnionitis at term patients was, respectively, 1.7 and 5.3% in preterm labor. In the total sample frequency of histologic chorioamnionitis was 0.6% (4 patients) and, of these, 25% were term and 75% with preterm rupture. In patients with premature rupture of membranes the clinical chorioamnionitis was 0% valued by the criteria of Gibbs. CONCLUSIONS: The premature rupture of membranes is a risk factor important for histological chorioamnionitis. To decrease risk factors and possible complications, an established protocol must be taken.
