Non-Cardiogenic Pulmonary Edema Due to Administration of Atosiban

We report the case of a pregnant woman, treated with atosiban for premature labor, who developed non-cardiogenic pulmonary edema. She corresponded initially to oxygen supplementation and furosemide administration to induce diuresis but the onset of preterm contractions combined with aggravation of respiratory failure led the patient to a cesarean section, and subsequently to the intensive care unit where she remained intubated for 24 hours. In this case report, we emphasize the importance of distinguishing between two types of pulmonary edema: cardiogenic and non-cardiogenic. The instant separation between these two categories, most of the time with transthoracic echocardiography while the patient is on early support of ventilation, increases the optimum outcome for the patient.
