[Anesthetic Management of a Parturient with Eclampsia, Posterior Reversible Encephalopathy Syndrome and Pulmonary Edema due to Pregnancy-induced Hypertension].
A 27-year-old woman with mental retardation was admitted to a nearby hospital for an abrupt onset of seizure. Physical examination revealed remarkable hypertension and pregnancy with estimated gestational age of 28th week. Severe pulmonary edema and hypoxia led to a diagnosis of pregnancy-induced hypertension (PIH) accompanied by eclampsia. She was orotracheally intubated because of refractory seizure and hypoxemia, and transferred to our hospital for further treatment. Besides severe hypoxia and hypercapnea, an enhanced lesion was detected in the left posterior cerebrum by brain MRI. No abnormal findings were detected in the fetus, with heart rate of 150 beats x min. She was diagnosed with posterior reversible encephalopathy syndrome (PRES) caused by PIH and emergency cesarean section under general anesthesia was scheduled. A male newborn was delivered with Apgar score of 1/4 (1/5 min), followed by starting continuous infusion of nicardipine for controlling hypertension. Chest X-P on completion of surgery revealed remarkably alleviated pulmonary edema. She received intensive treatment and continued positive pressure ventilation for four days after delivery. She recovered with no neurological deficits and her child was well without any complications.
