Abstract
A 28-year-old woman with quadruplets was scheduled for cesarean section. She felt chest discomfort when in a supine position because of a huge uterus. Hypoxemia and hypotension were anticipated if anesthesia was induced in a supine position. We, therefore, induced her anesthesia in a lateral position. After intratracheal intubation in a lateral position, she was set in a supine position. One of the operators maintained continuous left uterine displace-ment to minimize aortocaval compression. As a result, hypoxemia and hypotension did not occur. We used epidural anesthesia with in haled anesthetics because using only inhaled anesthetics may necessitate deepening anesthesia to avoid unfavorable hypertension or intraoperative awareness, and this deeper anesthesia may result in depressed fetuses. Our combination of anesthesia was satisfactory.
