Filter by:The aim of this study is to compare the efficacy of epidural and IV analgesia in controlling pain in patients undergoing Nuss repair of pectus excavatum. The primary end point will be the mean pain score during postoperative days 0-4.
Pectus excavatum, the most common chest wall deformity, occurs in roughly one in 1000 children. Operative repair of the anterior thoracic concavity has transitioned to the minimally invasive approach with substernal bar placement through small axillary incisions (Nuss procedure and multiple modifications). These procedures were quickly incorporated by high volume centers around the world including our own. The operation is certainly quicker and associated with less blood loss than the open operation, but as opposed to most minimally invasive versions of an operation, patients do not leave the hospital sooner after bar placement and experience more post-operative pain. Pain during the post-operative hospital stay is the dominant management issue after bar placement. The sparse literature on the topic has suggested that a thoracic epidural is the most effective means for attenuating the pain during the first few post-operative days. Therefore, most centers approach all patients undergoing a pectus deformity repair with an attempt at epidural placement under the assumption that this provides the most effective strategy for pain control. However, the investigators conducted a retrospective evaluation to examine the validity of this assumption and to investigate whether there is a role for a prospective study to determine the optimum post-operative pain management of these patients. The results demonstrate there was a decreased length of stay in the patients not treated with an epidural (PCA), despite no disadvantage in pain control. Further, 30% in whom an epidural was attempted, catheter placement failed. This data certainly challenges the assumption that an epidural is the optimum management for these patients, and convincingly answers the question as to whether there is a role for a prospective randomized trial.
Post-operative nausea and vomiting (PONV) is not only unpleasant for patients but also can delay hospital discharge and increase cost of stay. In some cases, when severe vomiting occurs, pain scores seem to be increased. The overall incidence of PONV is 30% and increases to 79% in patients at high risk for this post-operative outcome. The NUSS procedure is considered to be a procedure with a high risk for the outcome of nausea and vomiting.
