Research Abstract
Dr. Choi is evaluating pulse oximetry (a noninvasive system designed to measure arterial oxygen saturation) as a monitor of respiration during epidural morphine analgesia. This type of analgesia is used to lessen postoperative pain, particularly postcaesarean section pain. Dr. Choi also is evaluating epidural administration of sufentanyl with local anesthetics for relief of labor pain.
