Filter by:The goal of this pilot study is to learn if a class and hands-on-practice of ergonomic body positions - or specific ways to move the body while working to prevent injury - is valuable to training obstetrics and gynecology doctors. The main questions the study team aims to answer are: - Will these lessons successfully teach the participants how to move bodies at work in a way that will prevent injury? - Will the participants feel that learning and practicing such lessons helps to avoid injury while at work? Researchers will compare training obstetrics and gynecology doctors that attend a class on ergonomics and have guided hands-on-practice of ergonomic body positions with training obstetrics and gynecology doctors that attend the class only to see if the first group learns and remembers how to move their bodies safely while working. All participants will attend a class that teaches basic ergonomic lessons before they are divided into two groups. Group 1 will practice common surgery skills on a model while being videotaped by an artificial intelligence application. The application will make a report on unsafe positions a participant does while practicing surgical skills. The Group 1 participant will then go over the report with one of the study supervisors to talk about ways that the participant can move safely while practicing the skills. The participant will then practice the skills one more time while being videotaped. The study supervisors will then compare the two reports to see if the participant improved. Group 2 will also practice common surgery skills on a model while being videotaped. Group 2 participants will not get to see the report that the application generates or speak with the study supervisors about ways to move safely while practicing the skills. There will be a follow up after two months to see if participants remembered what was learned during the class and during the hands-on practice lesson. All participants will again be videotaped. The study supervisors will compare the videos and reports from the last class to the most recent ones to see if the participants learned and remember how to move safely while working. Participants in both groups will take a quiz about the lessons learned in the class before and after the class to determine what had been learned from the lesson. A survey about how useful and helpful the class was and hands-on practice sessions were will also be completed.
TrEnd trial is aimed to collect data from consecutive patients undergoing segmental sigmoid colon/rectal resection for deep endometriosis. The main purpose of this project is to gather a large series of cases treated using standardized surgical procedures, allowing a precise evaluation of complications and long-term outcomes.
In 2023, oral anticoagulant treatments (anti Xa: apixaban , rivaroxaban, etc.) are tending to replace anti vitamin K treatments in many medical indications. Their prescription is increasing rapidly in the elderly. In this context, the Nimes University Hospital receives a large number of elderly patients who have suffered a fracture of the end of the femur requiring surgery and who are taking anti Xa drugs.To avoid massive intra- and post-operative haemorrhage, surgical management is postponed because of the need to suspend the treatment, allowing a return to near-normal biological haemostasis within a few days. No consensus has been reached on the withdrawal period required to authorise surgery, as the elimination kinetics of the drug are altered in this context (elderly patients, dehydration, hypovolaemia, impaired renal function). A plasma assay (threshold of <30 to 60 ng/mL) has been proposed without any real justification. This waiting period exposes the elderly to excess mortality. Reversing these treatments by adding coagulation factors would be an attractive alternative, as it would allow surgery to be performed earlier, but this would expose patients to an increased thrombotic risk. Before considering a prospective randomised study (early vs delayed surgery on AOD), we wish to retrospectively analyse data on patients admitted to the Nimes University Hospital on anti Xa and operated on for fracture of the upper end of the femur between 1 January 2022 and 1 June 2023
The aim of the study is to investigate how the combination of ropivacaine (a slow onset, long duration local anesthetic) with lidocaine (a rapid onset, shorter duration local anesthetic) affects the onset and duration of a lateral infraclavicular plexus brachialis (LIC) block in patients undergoing non-acute hand surgery.
The goal of this prospective study is to investigate the satisfaction, NASA-Task Load Index (TLX), and surgical proficiency of a robotic breast surgery education program using cadaver or porcine models, as well as to develop an AI-based surgical guide for utilization within the educational program in trainees for robotic breast surgery. The main question[s]it aims to evaluate : - Satisfaction questionnaire of a educational program - NASA-TLX of a educational program - global evaluative assessment of robotic skills (GEARS) of a robotic breast surgery for surgical proficiency Participants will participate the educational program and fill out a satisfaction questionnaire and NASA-TLX. The tutor evaluates GEARS for 15 minutes at the beginning and end of training. After the development of the surgical guide based on AI, researchers will compare a training group with or without surgical guide to see the effect of the surgical guide.
The genu pectoral position is a surgical position used for spine surgery. This surgical position will lead to physiological hemodynamic and respiratory changes during the procedure. The knee-pectoral position notably induces an increase in CRF and improves pulmonary ventilation/perfusion ratios. On the other hand, it has been shown that it is accompanied by a reduction in cardiac output of approximately 15% Protective perioperative ventilation including a tidal volume between 6 and 8 ml/kg of theoretical ideal weight, PEEP and alveolar recruitment maneuvers is applied in the operating room to reduce postoperative pulmonary complications. The application of high PEEP and the performance of recruitment maneuvers induce arterial hypotension through changes in intra- and transpulmonary pressures. However, investigators hypothesize that the deleterious hemodynamic effects of PEEP seem to counterbalance its beneficial respiratory effects in this particular position. The combination of the effects of the knee-pectoral position and protective ventilation could be potentiated and be the cause of the sometimes severe arterial hypotension observed in clinical practice. Since this position improves pulmonary ventilation perfusion ratios, the investigators hypothesized that a lower PEEP and the elimination of intraoperative recruitment maneuvers could be beneficial from a hemodynamic point of view without being deleterious in terms of perioperative pulmonary complications. An exploratory study was carried out at the CAEN University Hospital in 2021 under the name PEEP POSTURE (CLERS Agreement No. 2198 of February 17, 2021) on 90 patients aiming to collect hemodynamic and respiratory parameters in 3 surgical positions: supine decubitus, ventral decubitus , pectoral genu. No difference was found in the evolution of respiratory compliance. On the other hand, a significant drop in SBP, DBP and MAP in the pectoral position was shown compared to the supine group as well as greater vascular filling. The investigators therefore hypothesize that a reduction in PEEP and optimization of vascular filling could help reduce the adverse effects on blood pressure linked to the surgical position.
Given the scarcity of studies aimed at assessing the effect of anesthesia and m ventilation on the distribution of lung ventilation in pediatric patients undergoing surgery, with the exclusion of thoracic surgery, the present prospective observational study would shed the light on ventilation practice in pediatric anesthesia for surgery. This study wold fill the actual gap allowing the evaluation, through electrical impedance tomography (EIT) of the distribution of lung ventilation across the different phases of anesthesia for pediatric surgery. These insights could contribute to improve clinical practice and research in the management of ventilation in pediatric patients undergoing anesthesia for surgery.
This trial aims to demonstrate that the Neuralert Monitoring System will detect strokes before they would be identified by current standard of care. Each patient will be monitored for up to five days, depending on device connectivity or battery duration. Each monitoring session will consist of wearing a Neuralert device on each arm. For this pilot trial, we are interested in learning about Wi-Fi connectivity, successful data transmission, clinical usability, and tolerability.
Neuromuscular scoliosis (SNM) are deformities related to the impairment of normal function of the central nervous system (CNS) and/or peripheral nervous system (PNS) resulting in alterations to the of the functional unit represented by the integrated motor sequence (SIM). At the level of the spine, dysfunction of the SIM results in altered dynamic support of the spine. This results in a control of the trunk that is not harmonious due to the lack of effective mechanisms of muscle compensation. In particular, a greater degree of pelvic tilt with respect to the ground plane, with an increase in the degree of the so-called pelvic obliquity (OP), a fundamental parameter in walking and maintaining the seated posture. Spinal deformity causes severe alterations of the rib cage resulting in respiratory failure that often requires ventilatory supports and is associated with frequent airway infections, including pneumonias, often fatal. SNMs also express other comorbidities: cardiac (heart failure), neurological (epilepsy), nutritional that necessitate careful management multidisciplinary and especially anesthesiological evaluation for the peri-operative management. The surgical treatment of SNM constitutes a topic that is still debated due to both the bio-mechanical peculiarities of SNM and the clinical features, particularly comorbidities, that characterize this patient population. Compared with idiopathic scoliosis surgery, in SNM there is a higher rate of complications. To date, most of the complications are respiratory in nature (23%), followed by complications mechanical of the implanted surgical instrumentation (13%), and surgical site infections (11%). Furthermore, there is evidence that SNM surgery correlates with increased blood loss intraoperative. To date, it is recognized in the literature that the safest and most effective surgical treatment for SNMs is arthrodesis posterior instrumented with pedicle screws extended to the pelvis. In the years, mini-invasive surgical techniques have become increasingly prominent. invasive with the goal of reducing operative time, blood loss and complications themselves.
Researchers are considering Dexamethasone as preemptive medication before minimally invasive spine fusion surgery to minimize postoperative back pain with minimal side effects, aiming to enhance the effectiveness of surgery and improve patient outcomes.
