Résumé (français) :

Abstract (English):

OBJECTIVE: An extensive study as to whether maternal age itself is a risk factor for blood loss during parturition.

METHOD: A total of 10,053 consecutive women who delivered a singleton infant were studied. The excess blood loss was defined separately for women with vaginal and cesarean deliveries as > or = 90th centile value for each delivery mode. The effects of 13 potential risk factors on blood loss were analyzed using multivariate analysis.

RESULTS: The 90th centile value of blood loss was 615 ml and 1,531 ml for women with vaginal and cesarean deliveries, respectively. A low lying placenta (odds ratio [OR], 4.4), previous cesarean (3.1), operative delivery (2.6), leiomyoma (1.9), primiparity (1.6), and maternal age > or = 35 years (1.5) were significant independent risk factors for excess blood loss in women with vaginal delivery. Placenta previa (6.3), leiomyoma (3.6), low lying placenta (3.3), and maternal age > or = 35 years (1.8) were significant independent risk factors for excess blood loss in women with cesarean sections.

CONCLUSION: A maternal age of > or = 35 years was an independent risk factor for excess blood loss irrespective of the mode of delivery, even after adjusting for age-related complications such as leiomyoma, placenta previa, and low lying placenta.
