  • Postoperative Pain


The objective of this study is to scientifically evaluate two different management strategies for post-operative pain after pectus excavatum repair. The hypothesis is that pain management without an epidural decreases hospital stay without compromising comfort. The primary outcome variable is length of hospitalization after the intervention.

Study summary:

This will be a single institution, prospective, randomized clinical trial involving patients who undergo the minimally invasive repair of a pectus excavatum deformity with bar placement. This is intended to be a definitive study. Power calculations based on the known length of hospitalization listed above with α = 0.05 and power of 0.8 show the need for 55 patients in each arm. The primary end point will be reached during the hospital stay; therefore, we expect a very small amount of attrition and will intend to recruit 110. One group will undergo an attempt for epidural regional analgesia (epidural) for post-operative pain control. The other groups will receive patient controlled intravenous systemic analgesia (PCA). Both groups will have the same management algorithm. All data will be analyzed on intention-to-treat basis.


Inclusion Criteria: - Patients undergoing a pectus excavatum repair with bar placement. Exclusion Criteria: - Open repair - Re-Do operation - Known allergy to a pain medication in the protocol - Existing contraindications to epidural catheter placement - Requirement for 2 bars to be placed (rare) - Inadequate baseline cognitive function to understand/respond to VAS questionnaire

Study Interventions

Intervention Type:Drug
Name:Patient-Controlled IV Analgesia
Description:In the PCA arm, patients will receive fentanyl (3-6 mcg/kg) at anesthesia induction. Additional fentanyl may be administered intraoperatively as indicated. Patients who are > 35 Kg. (in keeping with current FDA approved labeling) will receive a clonidine 0.1 mg/day transdermal patch to the deltoid immediately after induction of anesthesia. Subjects in the epidural arm also receive clonidine. Upon arrival to the post anesthesia care unit, patients will be placed on a patient controlled anal
Arm Name:2
Intervention Type:Drug
Name:Epidural Analgesia
Description:Upon arrival to the operating room, patients will have a thoracic epidural (T 6-9) placed while in the sitting position. All epidural catheters will be inserted 3-5 cm within the epidural space and will be placed by attending anesthesiologists. Patients will receive midazolam 0.025 - 0.05 mg/kg IV (max 5mg) and/or fentanyl 0.5 - 2 mcg/kg IV for comfort during the procedure. Once the epidural is placed, the patient will be positioned for surgery. The epidural catheter will be initially bolused
