[Perioperative management for emergency cesarean section of a patient with reexpansion pulmonary edema]

A 27-year-old woman with 39 week gestation was admitted because of cough and dyspnea accompanied by massive right-sided pleural effusion. Following the right thoracocentesis, about 2000 ml of bloody pleural effusion was drained. Just after the thoracocentesis, the fetal heart rate (FHR) temporarily showed a variable deceleration pattern but the rate was restored spontaneously. One hour later, cough and dyspnea became worse. Changes in FHR pattern indicated the premature separation of the normally implanted placenta. Accordingly, an emergency cesarean section was performed under general anesthesia. Massive foamy tracheal secretion was drained from the tracheal tube during surgery. As her chest X-ray showed signs of pulmonary edema in the right lung, her status was diagnosed as reexpansion pulmonary edema (RPE). She was transferred to the intensive care unit and treated with mechanical ventilation, prednisolone and diuretics. Extubation was performed on the 2nd day after the surgery. On reexpansion of the collapsed lung, it is always necessary to consider not only the hemodynamic changes just after reexpansion but also RPE following reexpansion.
