Endometritis post-cesárea: factores de riesgo.

Abstract

SUMMARY Objective: To assess the risk factors for post-cesarean endometritis (PCE). Material and methods:A retrospective case-control study was carried out in the Obstetric Service at the Hospital Nacional Cayetano Heredia from January 1st, 1992 to July 31st, 1996. We used bivariate and multivariate analysis of logistic regression, for the statitical analysis. Results: During this period of time there were 82 patients with clinical diagnosis of endometritis. A control group of 82 patients who underwent cesarean section and had a normal puerperium were selected randomly. The factors associated with a significant risk for developing PCE with logistic regression analysis were: Maternal age less than 21 years old and post-operative hematocrit less or equal to 30%. In the group of patients with endometritis, 45.1% of them had a concurrent infection, being post-operative wound infection (29.3%) and urinary tract infection (11%) the most frequent ones.

RESUMENObjetivo: Determinar los factores de riesgo de endometritis post-cesárea (EPC). Material y métodos: Se realizó un estudio retrospectivo caso-control en el Servicio de Obstetricia del Hospital Nacional Cayetano Heredia del 1 de Enero de 1992 al 31 de Julio de1996. Para el análisis estadístico se utilizó análisis bivariado y multivariado de regresión logística. Resultados: Durante este período se detectaron 82 pacientes con diagnóstico clínico de endometritis, seleccionándose aleatoriamente igual número de pacientes operadas de cesárea con puerperio normal. Los factores relacionados con un riesgo significativo de EPC fueron: edad materna menor de 21 años y valores de hematocrito post-operatorio menor o igual a 30%. En el grupo de pacientes con endometritis el 45.1% de las pacientes tuvieron infección concomitante, siendo la infección de herida operatoria (29.3%) y la del tracto urinario (11%) las más frecuentes.
