Overwhelming maternal sepsis due to a gas-forming Escherichia coli chorioamnionitis.

We report a case of a patient who developed fulminant sepsis and respiratory distress caused by a gas-forming Escherichia coli intrauterine infection following premature rupture of the membranes and fetal death. Such gas-forming infections are rare, and, when they occur, they are usually caused by Clostridium welchii. This patient was treated with antibiotics, ventilator support, and hysterectomy, and at follow-up was in good health.
