Does Tranexamic Acid Decrease Blood Loss in Pediatric Idiopathic Scoliosis Surgery?
Adolescent Idiopathic ScoliosisAdolescent idiopathic scoliosis surgery is an extensive procedure associated with significant blood loss frequently requiring the transfusion of blood. Tranexamic acid (TXA) is a synthetic antifibrinolytic (prevents breakdown of the blood clot) that has been used to extensively reduce transfusion in pediatric major surgery, including cardiac, craniofacial and orthopedic surgery. In this prospective randomized double-blinded study, the investigators wish to evaluate the hypothesis that TXA is more effective than standard of care at decreasing blood loss and blood transfusion perioperatively in children and adolescents undergoing idiopathic scoliosis surgery.
Effects of Goal-directed Fluid Therapy on Post-operative Outcomes in Children Undergoing Scoliosis...
ScoliosisAcute Kidney InjurySurgery for scoliosis correction, the abnormal curvature of the spine, is a major procedure often undertaken in adolescents. In adult anesthesia, there is a large volume of literature debating how to optimize fluids administered during surgery, as both too much fluid and too little fluid are associated with worse outcomes. The investigators will compare fluid administration based on the measured amount of blood pumped by the heart during each heart beat (goal-directed therapy), against standard anesthetic management. The main outcomes are a) post-surgical kidney dysfunction, b) prevalence of intraoperative hypotension, c) volumes of administered fluids, and d) length of hospitalization.
Effects of a Spine Navigation System on Op-time and Radiation Exposure
Spinal StenosisScoliosis1 moreThe goal of this study is to prospectively collect information about the operative time and intraoperative radiation experienced by patients undergoing posterior spinal fusion procedures guided by the MvIGS spine navigation system.
Correlation Among Standing-sitting Sagittal Spinal Alignment, Paravertebral Muscle and Postoperative...
Degenerative ScoliosisThis is a prospective single-center study. Patients with adult degenerative scoliosis are prospectively enrolled and followed. All patients will take standard standing and sitting posteroanterior and lateral whole spine X-ray and lumbar MRI examination before and after surgery. Functional evaluation and radiographs were assessed preoperatively and postoperatively.This study will focus on the correlation among standing-sitting sagittal spinal alignment, paravertebral muscle and postoperative clinical outcomes in patients with adult degenerative scoliosis.
Effect of Pregabalin on Immediate Post-operative and Longterm Pain
ScoliosisSpondylolisthesisThis study aims to evaluate the incidence of longterm pain after spinal fusion surgery in children and adolescents. In the second part of the study a randomized double-blind clinical trial will be conducted. We compare the effect of pregabalin versus placebo on postoperative pain and oxycodone consumption. We will also be able to evaluate the effect of pregabalin on neurophysiological monitoring during surgery.
Experimental Evaluation of Back Braces for the Treatment of Spinal Deformity Produced With 3D Printing...
Adolescent Idiopathic ScoliosisOsteogenesis ImperfectaThe proposed investigation is a pilot study that involves pediatric patients affected by spinal deformity (Adolescent Idiopathic Scoliosis and Osteogenesis Imperfecta). The main goal is to evaluate the acceptability, the safety and the overall satisfaction of the patients wearing the back braces produced with an innovative methodology using 3D printers, compared to the current braces manufactured with a production model based on thermoforming, that has well-established clinical efficacy.
Surgical Treatment of Progressive Scoliosis With "NEMOST" Growing Rod
Progressive ScoliosisThe purpose of this study is to evaluate the performance of the device "NEMOST" on maintaining of the correction of the scoliosis with growth preservation and avoiding iterative surgeries. Objective of this study is to evaluate the performance of the growing device "NEMOST" associated to physiotherapy at 12 months postoperatively in patients treated for progressive scoliosis and to evaluate its safety.
Blood Propofol Concentrations in Children During Spinal Surgery
Spine DeformitiesIdiopathic Scoliosis1 moreDuring major spinal surgery evoked potential monitoring is performed to detect spinal cord damage. Intra-venous anaesthesia is the preferred anaesthetic technique because volatile anaesthetic agents supress the evoked potentials. Total Intra-Venous Anaesthesia (TIVA) with propofol is commonly administered as a Target Controlled Infusion (TCI). The TCI is an automated drug delivery system which administers propofol to achieve a desired blood concentration, based on an in built pharmaco-kinetic data (TCI model) derived from previous studies. The TCI model also provides a real time predicted blood concentration to facilitate the anaesthetist to adjust the target concentration of propofol. The TCI algorithm is based on pharmaco-kinetic data derived from previous studies in a relatively small number of patients, by a "best fit" relationship between blood levels, infusion rates and other factors (such as age and weight). Several factors make it possible for a wide discrepancy between the predicted and the true blood concentrations. This difference can be higher in children compared to adults. Also blood loss and administration of large volumes of intravenous fluids can affect the blood concentrations. This study aims to identify the difference between the predicted and true blood concentrations by using Pelorus 1500, a bedside blood propofol measurement device, in children undergoing major spinal surgery under TIVA.
IRB-HSR# 14145 R,S Methadone: Analgesia and Pharmacokinetics in Adolescents Undergoing Scoliosis...
ScoliosisThis is a pilot study to determine the pharmacokinetics of (R,S) methadone in adolescents. A total of approximately 15 patients will be required. The purpose is to determine the levels of R, S methadone at various time intervals after drug administration. Patients will receive methadone 0.25 mg/kg IV at induction and a standardized anesthetic of remifentanil and propofol. At the conclusion of surgery (45 minutes prior to the completion), the patients will receive a loading dose of morphine based on respiratory rate. A morphine PCA will be utilized for postoperative analgesia. Pharmacokinetic data will be collected in addition to VAS scores, patient and parental satisfaction with analgesia, and a functional pain assessment.
Influence of Leg Length Discrepancy on the Spinal Shape and Biomechanics in Functional and Idiopathic...
Leg Length DiscrepancyScoliosisThe purposes of this study are to use motion analysis techniques to study the biomechanical interactions between the spine and the lower limbs in scoliosis patients with or without leg length discrepancy (LLD) during activity; to investigate the effects of correction of LLD: using foot orthosis on the functional scoliotic spinal curve and motion during functional activity; and to test whether idiopathic scoliosis without LLD can be improved by artificially creating a leg length discrepancy with a foot orthosis.
