[Two cases of pulmonary edema during and after cesarean section].
Pulmonary edema occurred during and after Cesarean section under general anesthesia in two pregnant women. They had no preoperative complication. After delivery, anesthesia was maintained with 66% N2O in oxygen and intravenous injection of pentazocine and diazepam. At the same time, 0.2 mg of methylergometrin was injected intramuscularly and 2,000 micrograms of prostaglandin F2 alpha was injected to the muscle of the uterus in order to induce uterine contraction. In one case, SpO2 dropped and airway pressure increased immediately after the administration. In another case, chest rale was auscultated on postoperative round at 2 hours after operation. The cases suggest that pulmonary edema was caused by a large quantity of oxytocics, which increased volume load on systemic circulation.
