- Primary Outcome Measures
Name Time Method An epidural anesthetic will be continuously administered starting 30-60 minutes before the completion of surgery. After the patient awakens from the general anesthesia, a thermographic camera will be used to determine how many segments the wound site is apart from the site of the sympathetic ganglion block. Although it is an unlikely event, if the analgesic effect is assessed to be inadequate (less than 2 segments), 3 ml of 0.2% ropivacaine will be added; on the other hand, if the effect is assessed to be excessive(>5 segments), the flow rate of continuous anesthesia will be decreased. The severity of postoperative pain will be assessed by ward nurses on a 4-point scale based on the amount of rescue analgesic administered to the patient.
