Filter by:The objective of this qualitative prospective observational study is to analyze the cognitive aspect, the emotional-behavioral state and the quality of life of patients during their stay on the waiting list for two categories of lumbar spinal surgery: arthrodesis and percutaneous vertebroplasty. Hypothesis: Considering the existing evidence that associates some peculiar psychological components (expectations, beliefs, fears, coping strategies) of the patient and the outcome of spinal surgery, as well as the importance that the waiting time for the intervention assumes for recovery post-operative, this study aims to investigate the subjective perception of one's condition and the waiting period prior to the expected spinal surgery. This is a qualitative prospective observational study, monocentric with variable sample up to the level of saturation. The blind members are the staff who will listen to the recordings of the interviews and prepare the summary table of the same and the statistical researcher who will perform the analyzes. The selection of the participants will be carried out in such a way as to ensure a heterogeneous sample in terms of age, sex and experience and as representative as possible of the population studied. The number of participants in qualitative studies is usually determined by intentional sampling, based on the need to understand the full range of possible responses, to obtain the so-called data saturation. All patients on the waiting lists of the Department of Spinal Surgery, for vertebral arthrodesis or percutaneous vertebroplasty are considered eligible. The two types of surgery differ both in the surgical procedure and in the duration of the wait before surgery, which is 1-2 months for vertebroplasty and more than one year for spinal arthrodeses which are not of urgency or priority.
The bronchodilator effects of volatile anesthetics have been the subject of many clinical studies. It is known that all volatile anesthetics, especially halothane, have similar effects. Sevoflurane has been shown to reduce airway resistance more than halothane and isoflurane. Desflurane is difficult to use as an induction agent due to its harsh and extremely pungent odor and airway irritating effect. However, it has been shown that the risk of cough, respiratory arrest and laryngospasm is no different from sevoflurane when administered after intravenous induction. Although it irritates the airway, it is thought to have a bronchodilation effect as it stimulates the sympathetic system. In spinal surgeries, prone position is required to access the operating field. When the patient is placed in the prone position, pulmonary physiology are affected. In the prone position, V/Q mismatch decreases and arterial oxygenation increases. However, lung compliance decreases and the peak inspiratory pressure required to reach the required tidal volume increases. The main purpose of this study is the effect of volatile agents on lung mechanics and oxygenisation in the prone position.
Major spinal surgery causes greater pain in the postoperative 24 hours. Patients with severe pain may have prolonged hospital stays and delay in mobilization. In addition, chronic pain may be seen in these patients due to ineffectively managed acute postoperative pain. Therefore, optimizing acute postoperative analgesia is a priority in patients undergoing major spinal surgery. Recently, ultrasound-guided interfascial plane blocks such as thoracolumbar interfascial plane block (TLIPB)and the erector spinae plane block (ESPB) have been described in spinal surgery. Both blocks clinically seem to be safe and easily performed. The aims of this study are to compare the quality of recovery scores, overall morbidity and postoperative analgesia after major spinal surgery in patients receiving either TLIPB or ESPB.
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.
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.
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.
