Hemodynamic Repercussions of the Correction (Surgical and Non Surgical) of Pectus Excavatum-type...
Pectus Excavatumthis non-randomized prospective study of 2 longitudinal cohorts (surgical treatment group or orthopedic treatment group), will evaluate the hemodynamic repercussions of the correction (surgical and non surgical) of pectus excavatum-type thoracic deformities by measuring the cardiac output difference before and after intervention, measured by transthoracic impedancemetry, during an exercise stress test
Impact of Surgical Treatments of Thoracic Deformation on Cardiopulmonary Functions
Pectus ExcavatumPectus CarinatumPectus excavatum or carinatum are the most common congenital deformations of the ventral thoracic wall. Several different surgical methods with different techniques to correct these deformations have been described. Some clinicians recommend a correction of the deformation to improve the cardiopulmonary efficiency. Other think that the correction has a more an aesthetic than a physiological benefit. The aim of our prospective study is to evaluate whether patients with PE or PC are suffering preoperatively from a cardiopulmonary limitation at rest and under physical stress and if there is a change of cardiopulmonary function after the surgical correction.
Evaluation of a New Model of Metallic Bar and Stabilizer for Use in MIRPE
Funnel ChestPectus excavatum (PE) is the most common deformity of the chest wall, occurring in approximately 1/1000 people. Currently, surgical treatment by minimally invasive technique is consolidating as preferred technique for the treatment of this condition. In this technique a metal bar is inserted in retrosternal position, pushing the sternum without the necessity of resecting the condral cartilages. Despite the advantages obtained with this technique, it is not without complications and the displacement of the bar is one of the most important. In order to minimize this problem we developed a new model of stabilizers, as well as all necessary instruments for performing minimally invasive surgery. The aim of this study is to compare two surgical groups, one making use of the new oblique stabilizer compared to the conventional perpendicular stabilizer to determine which one has less displacement. Furthermore, this study also aims to assess the full range of instruments developed by a national company, to carry out this type of surgery, which has cost compatible with our economic reality, and that can be accessible to our Public Health patients.
Pain Management for Pectus Excavatum Repair
Postoperative PainThe 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.
Prospective Trial: Pain Management After Pectus Excavatum Repair, Epidural Versus PCA
Pectus ExcavatumPectus 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.
Hypnotherapy in Major Surgical Procedures
ScoliosisPectus ExcavatumThe purpose of this randomized controlled study is to test the feasibility of clinical hypnotherapy as a perioperative intervention for the reduction of pre-operative anxiety, post-operative pain, and other-related symptoms (nausea, vomiting, spasms, length of stay, self mastery) in children undergoing scoliosis repair or Nuss procedure.
The Effect of Surgical Repair of Chest on Postural Stability Among Patients With Pectus Excavatum...
Pectus ExcavatumThe goal of this study is to determine the effect of Nuss minimally-invasive repair technique of pectus excavatum (PE) on the postural stability in patients with PE. The main questions it aims to answer are: How surgical chest wall repair will affect postural stability of PE patients? What is the difference in postural stability between patients with PE and healthy controls? Participants will undergo the Nuss repair surgery and will be tested before and afterwards for their postural stability with the use of the posturography method. Researchers will compare PE male patients and healthy young men to see if PE posture defect affects postural stability.
Functional Capacity of Exercise and Lung Function in Patients Submitted Early Rehabilitation
Funnel ChestThe aim of this study was to compare the functional capacity of exercise by six-minute walk test and lung function by spirometry, before and after Nuss procedure in subjects who have undergone the early rehabiliation program with those who were under conventional care. Researchers want to find out if early rehabilitation is a strategy to enhance recovery after Nuss procedure.
Sub-Paraspinal Block in Nuss Patients. A Pilot Project
Pectus ExcavatumPain1 moreThe purpose of this pilot study was to evaluate effectiveness of a novel regional anesthesia technique developed at the investigators institution, as part of a quality improvement initiative, to assist with multilevel thoracic pain control in post-Nuss procedure patients. The investigators hypothesized that the local anesthetic infusion via bilateral multiperforated soaker catheters placed at extrathoracic sub-paraspinal muscle location under ultrasound guidance would significantly improve pain control, as reflected by the decrease in pain intensity score, reduction in opiate requirement and improvement infunctional rehabilitation measure scores in patients who underwent the Nuss procedure for pectus excavatum repair. However, the goal of this pilot study was not to detect a statistically significant difference in the primary outcomes between control and treatment groups (as the number of study subjects was chosen out of necessity of what could be completed within a specified time period), but to estimate the parameters which allows appropriate power and sample size calculations for a future multi-institutional study.
Comparison of IV PCA and Wound Infusion After Repair of Pectus Excavatum
PainSide EffectsPostoperative pain management is a major problem after repair of pectus excavatum.Various methods of pain management have been introduced. However, the effects of continuous wound infusion of local anesthetics through ON-Q catheters were not well evaluated in pectus surgery. Therefore, we conducted prospective randomized controlled study to compare the effects of IV PCA and continuous wound infusion after repair of pectus excavatum.
