Active clinical trials for "Funnel Chest"

The purpose of this study is to evaluate the efficacy of erector spinae plane (ESP) block in children after pectus excavatum repair (nuss procedure).

Pectus excavatum is the most common chest wall deformity in children, accounting for 90% of all congenital chest wall deformities. It occurs in one to eight per 1000 live births. The severity of the pectus deformity may become more noticeable during pubertal growth spurs and repair is therefore usually performed in the teenage years. A common operative procedure to repair a pectus deformity is the minimally invasive repair of pectus excavatum (MIRPE). The MIRPE involves the substernal placement of a contoured metal bar secured to the lateral aspect of the ribs. This metal bar allows for correction of the concave deformity by applying constant outward pressure to the underside of the sternum. Although the cosmetic results are excellent, patients do report significant pain from the constant pressure exerted on the chest wall from the metal bar. Pain management approaches tend to differ on both the provider and institutional level. There is a lack of evidence regarding which postoperative analgesia method is best. To address this research gap, this proposal aims to conduct a randomized controlled trail using the three most commonly used methods; 1) patient controlled analgesia (PCA); 2) erector spinae blocks (ESB) with continuous infusion pumps; and 3) video-assisted intercostal nerve cryoablation (INC).

Pectus excavatum (PE) is the most common congenital deformity of the chest wall and surgical treatment using the minimally invasive technique (MIRPE) is consolidating as the choice to perform PE correction. In this technique, a temporary metal bar is placed in a retrosternal position, pushing the sternum without the need for cartilage resection. Despite the advantages obtained, it is not free from complications, with the displacement of the bar being one of the main problems. Therefore, the aim of this study is to evaluate a new bridging device for the set of two metal bars to be used in the surgical treatment of PE, verifying the clinical and surgical complications and evaluating the change in lung volumes and thoracoabdominal kinematics using optoelectronic plethysmography , preoperatively and 180 days after MIRPE; and also evaluating diaphragmatic mobility via ultrasound examination to assess the craniocaudal displacement of the left branch of the vein preoperatively and 180 days later. There will be 20 participants, who after performing a computed tomography of the chest to obtain the Haller index, clinical and laboratory tests, electrocardiogram and echocardiogram. Participants will be randomized and divided into two groups: 10 control individuals (traditional MIRPE technique used in the Service) and 10 intervention individuals (with bridge fixators developed in partnership with Traumec Tecnologia e Implantes, Brazil). The effectiveness of the fixators will be evaluated by the degree of displacement of the bars, using a mathematical formula, using a lateral chest X-ray in the immediate postoperative period (d0) and another image from the end of the period analyzed (dX), 15, 30, 90 and 180 days after the surgical procedure; evaluation of postoperative pain through the numerical pain scale; use of validated questionnaires on quality of life (physical and mental health) using two instruments, SF-36 and PEEQ. All data obtained between the two groups will be submitted to descriptive and inferential statistics.

This study compared standard therapy (multimodal analgesia with 2 minutes cryoanalgesia) versus a novel approach (multimodal analgesia with 1 minute cryoanalgesia) in subject undergoing minimal invasive modyfied Nuss procedure with thoracoscopy.

The main objective of this study is to characterize the cardiorespiratory functional gain in patients with pectus excavatum following corrective surgery.

Cryoanalgesia for pain management after pectus excavatum repair. COPPER study (CryoanalgesiafOr Pain management after Pectus Excavatum Repair): a randomized controlled trial. Determine if, in patients more than 12 years of age having cryoanalgesia for pectus excavatum repair analgesia improves the standard of care (epidural analgesia) in term of pain relief and return to normal life 2 weeks after surgery. Randomized active controlled, parallel group, single-centre, trial (category IIb medical device). 88 patients aged more than 12 years of age scheduled for pectus excavatum repair. After randomization, patients will receive intraoperative cryo-analgesia or standard of care (epidural-analgesia). PedsQLscale (23 items) two weeks after surgery. Patients will be followed for 6 months after surgery to determine time until return to normal life and occurrence of any complication related to the use of cryo-analgesia. Numeric Rating Scale (NRS), CALI9, YAPFAQ will be measured at fixed times to determine pain intensity and limitations due to pain. Risk factors for prolonged pain and time needed until achieving discharge criteria from hospital will be reported.

The clinical study is testing a new treatment for pectus excavatum called "custom-made 3D printed scaffold-based soft tissue reconstruction". The new method uses a combination of the patients own adipocytes (fat cells) with a 3D printed scaffold (PCL Pectus Scaffold) to support soft tissue regeneration in the patient's chest using the body's natural healing processes. The implanted scaffold acts as a resorbable frame to support the growth of cells. The substance used for the scaffold is resorbable, it's similar to the substance used for sutures and stitches, and it's already TGA approved for bone reconstruction of the skull. The implanted scaffold degrades over time, leaving the tissue in its place.

The clinical study evaluates the use of a custom-made medical-grade polycaprolactone-PCL Pectus scaffold implantation with Autologous Fat Grafting for pectus excavatum camouflage (IT). The study aims to demonstrate the safety and clinical performance of the insertion of an absorbable "medical-grade polycaprolactone-PCL Pectus Scaffold" in the thorax region with Autologous Fat Grafting in the correction of congenital Pectus Excavatum unsuitable for conventional treatment with stable cardio-respiratory function. The PCL Pectus Scaffold-based design has the potential to induce sustained regeneration to fill large volume pectus excavatum defects, with the added benefit of being light weight and resorbable, thus not affecting the patients function capacity and reducing the risk of implant-related complications.

This will be a prospective study to determine the association between specific genotypes, epigenetics, behavioral, social and biological factors, with the phenotypes, defined by pain perception, postoperative pain, analgesic effects, side effects to perioperative analgesics, chronic postoperative pain, and gene expression in patients following pectus excavatum repair.

Primary objective of the current study is to determine the impact of intercostal nerve cryoablation on postoperative length of hospital stay compared to standard pain management of young pectus excavatum patients (12-24 years) treated with the minimal invasive Nuss procedure. The study is designed as a single center, prospective, unblinded, randomized clinical trial.
