Filter by:This is a prospective randomized controlled trial of the Suction-Integrated Surgical Tissue Elevator & Retractor [SISTER] device to assess: - Effects on operative time and efficiency of exposure in open lumbar spine cases. - Effect on total blood loss during the exposure part of the operation. - Rate of clogging of suction device.
Many studies are in favour of the importance of the rachis on the postural balance of the body.It is possible to study the upright posture by determining the center of pressure using a platform of strength.The spinal surgery have two objectives ,mechanic and neurologic .By deformation correction and stabilizing vertebral stages via arthrodesis, it seems to hypothesize that surgery can modify postural balance. This study aim to evaluate spinal surgery effect on posture using that plaftorm .
Low back pain is one of the most frequent reasons for consultation in rheumatology. There is a strong correlation between low back pain, and the presence of a type of Modic 1 signal on MRI. The anomaly Modic 1 results in a hypointense signal T1-weighted images and hyperintense on T2-weighted sequences (including T2 STIR and / or Fat Sat) and contrast enhancement of the endplates after gadolinium injection; it corresponds to a replacement of normal cancellous bone of fibrovascular tissue. The origin of this inflammatory process Modic 1 into the vertebra is still unknown. infectious hypothesis was raised, including contamination by germs called "slow-growth" such as Propionibacterium acnes (PA). Many studies interesting Bacteriological analysis of disc material found the presence of bacteria (prevalence between 0 and 54%). A recent clinical trial evaluating the efficacy of antibiotic treatment compared to placebo in low back pain with Modic 1; a show effectiveness of this treatment on the different clinical parameters evaluated. However skin contamination is not formally excluded, particularly in patients previously infiltrated (including epidural). Our hypothesis is that the slow-growing bacteria are not involved in Modic 1 type of disc disease, and the possible presence of PA or other slow-growing bacteria in samples obtained discal posterior approach would be related to intraoperative contamination or during preoperative spinal infiltrations The main objective is to assess the prevalence of germs slow growth in the intervertebral disc in the spinal surgery by anterior disc disease in type 1 Modic.
The aim of this Post Market Clinical Follow-up Study is to collect clinical data on the performance of Lyoplant® Onlay. To assess the performance of the product, various safety and efficacy parameters have been selected.
Transoesophageal ultrasound examination before and after prone position.
The primary objective of this investigation is to evaluate the performance of a self-adhesive absorbent post-operative dressing coated with a soft silicone layer in minimize the risk of the development of blistering in subjects after hip or knee arthroplasty or spinal surgery in comparison to a standard wound dressing The secondary objectives are to evaluate: - the performance of the dressing - the comfort, conformability and the acceptability of the dressing - pain before, during and after dressing removal - the overall cost regarding dressing wear time, time to do dressing change and personal resources needed
Chloride-rich isotonic crystalloid solutions have been shown to exert electrolyte imbalance and metabolic acidosis in critically ill patients. The aim of this investigation is to compare the influence of 0.9% saline and plasmalyte solution on acid-base balance and electrolytes in healthy patients undergoing major spine surgeries.
A newly developed monitor for continuous non-invasive blood pressure monitoring (CNAP™ Monitor 500; CNSystems Medizintechnik AG, Graz, Austria) provides beat-to-beat BP readings and is non-invasive. To make sure that anaesthesiologist can rely on and make clinical decisions based on values provided by the CNAP™ monitor, to demonstrate its reliability we will test it during the perioperative care of children.
- Pain is one of the most common concerns for which patients seek medical attention. - Pain is usually understood as symptom that reflects peripheral organic damage. Many patients experience pain, often chronically, independently of any underlying cause such as chronic regional pain syndromes (irritable bowel syndrome, temporo-mandibular pain syndrome, chronic headache or chronic low back pain)or diffuse like in fibromyalgia. In all those "functional" syndromes, accumulated evidence supports involvement of central pain processing systems, hypothalamic pituitary adrenal axes and autonomic nervous system, and are now referred as central pain conditions. - Other patients suffers from chronic pain caused by damage or inflammation in peripheral tissues, but also experienced more diffuse pain, not directly explained by peripheral damage, that further aggravates pain and function. This is illustrated by the high prevalence of fibromyalgia observed in patients with rheumatoid arthritis, osteoarthritis or ankylosing spondylitis for example. These pain conditions are now understood as combinations of peripheral, neuropathic and central pain. The investigators aimed to focus in this study in patients that are candidates to spinal surgery and suffer from low back pain and/or radiculopathy. Pain in these patients may arise from damage to nerves - neuropathic pain- , to musculoskeletal structures - peripheral pain-, and may also reflects alteration in central pain processes. In these patients, spine surgery is usually performed to improve quality of life, decrease pain and avoid neurological deficits. Evaluation of surgical outcome includes objective measures such as neurological findings and radiographic evaluation, and subjective measures including patient self-assessments for pain and quality of life and psychological changes. The aim of this study is to evaluate patients who undergo spinal surgery for presence of central pain and central sensitization symptoms and evaluate their influence on these surgical outcomes
The study is an open, randomized, controlled, single-centre study including a total of 42 evaluable subjects scheduled for spinal surgery with an approximate expected bleeding of 800-1500 ml. The Sangvia® Blood Salvage System will be set up for all subjects to collect blood intra-operatively. When the transfusion bag is filled, i.e. when around 500 ml of blood has been collected, the subject will be randomized to either be retransfused with the blood collected (investigational group) or not (control group). The primary objective for this study is to investigate the blood quality and isolate the systemic effects in intra-operatively collected blood. The systemic p-Hb concentration has been chosen as the primary outcome variable based on previous experience and literature and is considered as the major safety concern for the study subjects.
