Fluoroscopy-guided Versus Traditional Placement of Epidural Catheters

This is a prospective, randomized, controlled, and single blinded study. All work performed at Dartmouth-Hitchcock Medical Center, a tertiary care and level one trauma center for the state of New Hampshire with 28 operative suites. 100 patients scheduled to undergo thoracotomies are randomized to receive an epidural placed (for postoperative pain control) using either a traditional approach by feeling the spine for landmarks or using fluoroscopic X-ray guidance. Randomization is blinded to both the anesthesia team caring for the patient in the operating room and to one member of the acute pain team who follows the patient after surgery and is responsible for evaluating post operative pain control (dermatomal distribution of sensory blockade and visual analog scale) and pulmonary function (incentive spirometer use). All patients receive a standardized epidural infusion with local anesthetic and additional pain medications as needed.
