Filter by: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.
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.
The aim of this single-centre prospective randomized-controlled clinical trial is to assess whether patients adhere to prescribed weight bearing limits after surgical orthopaedic or traumatological interventions more accurately after instruction using a biofeedback method than using the standard method.
Breast-conserving surgery is the standard treatment for young breast cancer patients, while mastectomy with breast reconstruction is an alternative for those who are not eligible for Breast-conserving surgery. Several studies have compared the quality of life and patient satisfaction among individuals receiving different types of surgery (Breast-conserving surgery, mastectomy alone, or mastectomy with reconstruction). For example, Meghan R. demonstrated that patients undergoing Breast-conserving surgery experience a higher quality of life compared to those undergoing mastectomy with breast reconstruction, whereas J. Dauplat's study showed that patients who undergo mastectomy with breast reconstruction report a higher quality of life than those who undergo mastectomy alone. However, the investigators hypothesize that the advantages of a specific type of surgery over another, such as Breast-conserving surgery versus breast reconstruction, may vary among patients with different socioeconomic factors. For instance, the benefits of breast reconstruction over Breast-conserving surgery might be more pronounced in young patients who require a more socially active lifestyle. Additionally, the benefits of one type of surgery over another may also vary at different time points during post-operative follow-up. Furthermore, it is worth noting that most current studies have been conducted in Caucasian populations. In contrast to Caucasians, Asians typically have smaller breast volumes, potentially leading to more significant defects after Breast-conserving surgery and possibly poorer aesthetic outcomes. Therefore, a study focusing on Asian young breast cancer populations is necessary.
A novel device that works with robotic trocars to clean the scope when visualization is compromised during a surgical procedure.
The incidence of postoperative delirium in elderly patients is high, which can lead to long-term postoperative neurocognitive disorders. Its high risk factors are not yet clear. At present, there is a lack of early diagnosis and alarm technology for perioperative neurocognitive disorders, which can not achieve early intervention and effective treatment. By artificial intelligence and autonomously evolutionary neural network algorithm, relying on multi-source clinical big data, we explored the use of Bayesian network to optimize the anesthesia decision-making system in enhanced recovery after surgery, and established risk prediction model for perioperative critical events. It is expected that this method will also help to establish a risk prediction model for postoperative delirium and long-term postoperative neurocognitive disorders. This project plans to collect the perioperative sensitive parameters of anesthesia machine, multi-parameter monitor, EEG monitor,fMRI and HIS system, to explore the evolution process of data characteristics by feature fusion.We also plan to quickly screen key perioperative risk characteristics of postoperative delirium from massive clinical data through feature selection, to explore the high risk factors of long-term postoperative neurocognitive disorders developing from postoperative delirium. Finally, with multi-center intelligent analysis，the risk prediction model of postoperative delirium and long-term postoperative neurocognitive disorders will be constructed.
Although unprecedented advances have been made in the field of esophageal cancer in recent decades, the prognosis for patients with locally advanced esophageal squamous cell carcinoma (ESCC) remains extremely poor, accounting for 30-40% of overall survival at 5 year. In recent years, multimodal treatments have proven to be an appropriate therapeutic approach for locally advanced ESCC. Recently, immunotherapy developed rapidly. The purpose of this study was to observe the efficacy and safety of cardonilizumab combined with chemoradiotherapy in the treatment of locally advanced ESCC.
The study is a randomized, double-blind, controlled trial evaluating the efficacy of 2% lidocaine gel in reducing postoperative pain and analgesic consumption after haemorrhoidectomy. 222 patients undergoing Ferguson haemorrhoidectomy will be randomly assigned to receive either 2% lidocaine gel or a non-anaesthetic lubricant gel control. Pain scores using a visual analog scale (VAS) will be assessed at 12 and 24 hours, and 2, 3, and 7 days postoperatively. Analgesic consumption will also be measured.
in healthy patients undergoing elective surgery, after a very slow induction, using Eleveld's kinetics as a reference, after loss of consciousness (LOC) and intubation, proceed to infuse propofol until 1% burst suppression ratio is obtained. Then return to the LOC concentration. The BISindex predicted by the model and the real one will be evaluated. The evolution of spectral density frequencies over time will also be evaluated.
The goal of this clinical trial is to learn if the artificial intelligence technology helps to improve the efficiency in robot assited spinal surgery. The main questions it aims to answer are: Does the AI technology shorter the mannual planning time of screw trajectories？ Does the AI technology affect the surgical accuracy？ Researchers will compare the artificial intelligence technology to the conventional mannual planning in robotic surgery. Participants who met inclusion criteria and do not have any exclusion criterion will be randomized to artificial intelligence or mannual planning group.
