Evaluation of amniotic fluid for aerobic and anaerobic bacteria

Abstract

Studies of 117 pregnant women, 83 at term, were instituted to determine the bacteriologic state of amniotic fluid, utilizing both standard aerobic and anaerobic technics. A high association of postpartum infection was found in women who had long periods of premature reptured membranes and many vaginal examinations. Significant organisms including anaerobes, were isolated in many of these instances. Based on the findings of these studies, it is recommended that amniocentesis for aerobic and anaerobic cultures be done when membranes have been ruptured for 8 hours or more, and when the patient has had seven or more vaginal examinations during the course of labor.
