Background

Continuous epidural infusion (CEI) of a local anesthetic combined with patient-controlled analgesia (PCA) is an effective postoperative analgesic approach for thoracic surgery.[1] However, CEI has some disadvantages, such as increased local anesthetic consumption and a limited area of anesthetic distribution.[2]

Programmed intermittent bolus (PIB) is a technique of epidural anesthesia in which boluses of local anesthetic are automatically injected into the epidural space. This technique increases the analgesic area.[3] Reports have indicated that intermittent epidural bolus administration reduces local anesthetic usage and improves maternal satisfaction in labor analgesia.[4–6] However, the usefulness of PIB in thoracic surgery is unclear.

The purpose of this study was to compare the efficacies of PIB epidural analgesia and CEI in patients undergoing thoracic surgery.
