A Prospective, Randomized, Controlled Trial of Post Operative Pain Control Using Ropivacaine and the ON-Q System in the Adult Pectus Excavatum Patient After Minimally Invasive Repair
In Brief
A clinical study evaluating ON-Q soaker catheter system and Epidural (ropivicaine 0.25%) for Pectus Excavatum. Completed, enrolled 85 participants across 1 site.
Detailed Summary
Pectus excavatum (PE) is a common chest wall deformity where the sternum is displaced posteriorly. In severe cases, surgery is performed to correct the defect. In recent years, minimally invasive surgery with the placement of stainless steel support bars has been increasingly performed in patients over the age of 17 years. Because of the decreased malleability and tremendous pressure required to hold the chest wall in the corrected position, post-operative pain control has been a significant problem in this patient population. Thoracic epidurals are commonly employed however mean hospitalizations of up to 7 days have been required before adequate pain control on oral analgesics is obtained and patients are suitable for discharge. It is hypothesized that using the ON-Q system (I-Flow Corporation, Lake Forest CA) with bilateral intercostal catheter infusion would provide adequate post operative pain control with a significantly shorter hospital length-of-stay than thoracic epidural. Total use of narcotics for 1 week following surgery would also be less with the ON-Q system versus epidural.

Timeline
Interventions
ON-Q soaker catheter system with Ropivicaine at 7 cc per hour placed by a single surgeon in the operating room. 7.5" catheters will be tunneled subcutaneously in the anterior axilla bilateral and secured with steri-strips and dressing. ON-Q systems will be primed with 750 cc and refilled accordingly to provide for 6 days of analgesia. Catheters will be removed by the surgeon in the hospital or clinic on the 6th post operative day. Patients may request removal of the catheter prior to the 6th day and this will not be considered a withdrawal from the study or complication and will be included in overall analysis, but noted accordingly.
Thoracic epidural with Ropivicaine 0.25% placed pre-operatively by the anesthesiologist. Epidurals will remain in place for 72 hours and discontinued by the anesthesia pain management team.
