[Case of general anesthesia combined with epidural anesthesia in a pregnant woman undergoing thoracotomy for spontaneous pneumothorax].
General anesthesia combined with epidural anesthesia for thoracotomy due to spontaneous pneumothorax was given to a pregnant woman at 21st week of gestation. She was premedicated intravenously with famotidine 20 mg and metoclopramide 10 mg. Mepivacaine 1% was administered through a thoracic epidural catheter. General anesthesia was induced by thiamylal 225 mg, vecuronium 8 mg and fentanyl 100 mcg, and maintained by sevoflurane, vecuronium and fentanyl. Endobronchial intubation with a 35Fr Bronchocath double-lumen tube was successful and one-lung ventilation was commenced to maintain the end-expiratory CO2 pressure at 30 to 35 mmHg with Sp(O2) remaining 100%. Ephedrine 16mg (in 4mg increments) was required to maintain systolic blood pressure above 100 mmHg. After the surgery, ropivacaine 0.2% was administered through the catheter. There were no clinical signs of fetal distress during the perioperative period. Postoperative pregnancy and delivery were uneventful. We succeeded in the anesthetic management by avoiding hypoxia, hypercapnia, hypocapnia and hypotension during the surgery.
