NCT ID: NCT06453161 Completed - Surgery Clinical Trials

Pre-operative Exposure to SGLT2 Inhibitors and Post-operative Acute Renal Failure in Cardiac Surgery: a Retrospective Monocentric Cohort Study

SGLT2i
Start date: April 1, 2024
Phase:
Study type: Observational

Cardiac surgery with cardiopulmonary bypass exposes patients to the risk of post-operative acute kidney injury. In the specific setting of cardiac surgery, acute kidney injury is often of multifactorial origindue to particular haemodynamic mechanisms, renal hypoxia, or damage linked in the inflammatory reaction or haemolysis (1). In recent years, inhibitors of the sodium/glucose co-transporter type 2 (SGLT2i) have demonstrated their relevance in reducing the morbidity and mortality associated with chronic or acute heart failure and chronic kidney disease. These drugs were initially developed to optimise glycaemic control in diabetic patients. They are currently recommended as part of the management of diabetic patients at high cardiovascular risk, patients with systolic and/or diastolic heart failure, and patients with chronic kidney disease. Some pharmacodynamic properties of SGLT2i suggest that they could have a beneficial effect in preventing the onset of acute kidney injury, but also that they could lead to potentially deleterious effects in renal haemodynamic in specific situations. The aim of the study was to estimate the impact of pre-operative exposure to SGLT2i on the occurrence of post-operative acute kidney injury in high-risk renal patients undergoing cardiac surgery.

Evaluation of the Use of the RELAX® Glasses on the Anxiety of Patients Undergoing Emergency Hand Surgery Under Locoregional Anesthesia

RELAX
Start date: May 2, 2022
Phase: N/A
Study type: Interventional

More than 90% of hand surgery is performed under local anesthesia and can be a source of anxiety, especially in an emergency context. The management of this intraoperative anxiety is essential for the comfort. The use of a virtual reality headset has shown its effectiveness in reducing anxiety in dental surgery or hand surgery under local anesthesia with the WALANT technique. On the other hand, virtual reality and the use of 3D can cause discomfort and side effects such as nausea and dizziness. It is known that audiovisual distraction also effectively reduces pain and anxiety in patients with fewer side effects. The investigators have therefore chosen to use the RELAX® glasses. There are no publications examining the effectiveness of positive distraction as a non-pharmacological agent to improve the patient experience during emergency management in the operating room in the context of hand surgery under locoregional anesthesia. The investigatos would like to study its action on the anxiety, pain and global satisfaction.

NCT ID: NCT06428877 Completed - Surgery Clinical Trials

Monocentric Retrospective Observational Study; Analysis of Gore Excluder ACS Device Using Numerical Simulation

ACSSim
Start date: June 15, 2023
Phase:
Study type: Observational

andated when the risk of rupture is low and interventional treatment is offered to patients at high risk of rupture. Rupture risk is driven by aneurysm diameter and growth rate. Aneurysms with diameter greater than 55 mm and/or growth rate greater than 1 cm per year are at high risk of rupture. Open surgery and endovascular treatment are the two types of interventions. Open repair consists in replacing the aneurysmal part of the aorta using a synthetic fabric prosthesis after the abdomen has been opened and the aorta clamped. This invasive procedure is associated with a 3-10% post-operative mortality. Endovascular repair (EVAR) consists in excluding the aneurysm sac by inserting a self-expanding prosthesis (called stent-graft) through very small groin incisions, without abdominal opening nor aortic clamping. This minimally invasive procedure is associated with a significantly reduced post-operative mortality (around 1%) . However, hostile proximal neck anatomy including high angulation is associated with higher rates of type IA endoleak, reintervention and long-term mortality . For this reason, a conformable design of the Excluder stent-graft has been engineered with initial satisfactory results in patients with highly angulated or short necks . However, these satisfactory results have been obtained in carefully selected patients from experienced centers and a tool demonstrating adequate apposition of the Gore ACS is lacking. Study Device Description Numerical simulation has been used successfully to predict stent-graft behavior during FEVAR . Preliminary studies have also demonstrated to applicability of the technology to standard infrarenal devices , including in the setting of very tortuous anatomies9 . The potential of numerical simulation to predict stent-graft apposition of Gore ACS in highly angulated necks appears very promising to enhance patient selection.

NCT ID: NCT06382584 Completed - Surgery Clinical Trials

Impact of Treatment With Oral Anticoagulants of Patients With Fractures of the Upper End of the Femur

ANTI_XA
Start date: January 1, 2022
Phase:
Study type: Observational

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

NCT ID: NCT06361069 Completed - Anxiety Clinical Trials

Reducing Anxiety in Children Undergoing Day Surgery

Start date: April 1, 2023
Phase: N/A
Study type: Interventional

Aim: This study was conducted to determine the efficacy of finger puppets, distraction cards and kaleidoscope for reducing anxiety in children undergoing day surgery. Methods: The study was conducted using the "pre-post test unmatched group model", one of the quasi-experimental methods. The study was conducted between April 2023 and January 2024 with children aged 6-12 years who were admitted to the pediatric clinic of a hospital for day surgery. A total of 85 children (including 20 children in the control group, 22 children in the finger puppet intervention group, 21 children in the distraction cards intervention group, and 22 children in the kaleidoscope intervention group) who were hospitalized in the pediatric clinic between April 2023 and January 2024 and who met the inclusion criteria were included in the study.
