Filter by:Neuraxial anesthesia has traditionally been a 'blind' technique relying on users' feel and skill, both are subjective, lack complete accuracy and influenced by patient's physique variations that are quite challenging, and lead to patient morbidity, infection, and nerve injury. The ultrasound(US) use allows real-time views of needle position thereby achieving higher success rates, fewer complications, and reduced patient discomfort. While US guidance for neuraxial procedures is popular, it is still relatively uncommon due to technical and anatomical challenges. The study investigators have created an innovative methodology to use with HoloLens, an augmented reality tool, to provide an accurate live road map for the needle path hidden under the patient's skin. This see-through model is an objective alternative to the user's memory for direct visualization of the needle virtual trajectory as it passed through the tissue and towards the 3D printed bone. Also, this model may have a variety uses in anesthesia.
Regional anaesthesia has many advantages but it might be a stressful and painful experience. Usually, the anesthetist administers a pharmacologic intravenous sedation to achieve patient's comfort. Though, these medications are not benign, and disadvantages include unpredictable response, adverse effects, and interference with cooperation. The virtual reality hypnosis distraction (VRHD) could be a good non-pharmacological technique to improve patient's comfort, decrease anxiety and procedure related pain. This study is a prospective study where sixty patients scheduled for orthopedic surgery requiring regional anesthesia were randomized in three groups according to the use or not of VRHD during the regional procedure or before as a complementary premedication. The anesthetic management during the regional procedure and the surgery remained otherwise standard for each patient. The first endpoint is the proportion of patients receiving pharmacological sedation (in the VRHD groups compared to the pharmacological sedation group). . The second endpoint is to determine if the VRHD increases the patient's satisfaction of their anaesthetic management. The third endpoint is to study various parameters of use of this specific anaesthetic management: time required for the installation and operation time of the VRHD device; the variation of haemodynamic parameters between the separate groups; pain procedure-related and behavioural pain scale scores between the separate groups.
Background: There is a lack of studies regarding Optimal (best) positive end-expiratory pressure (PEEP) in prone position during surgery, and its relation with optimal PEEP in supine position. Hypothesis: In patients undergoing scheduled spinal surgery, optimal PEEP in the prone position is lower than optimal PEEP in the supine position. Aims: To assess the difference optimal PEEP in supine vs. prone positions in patients undergoing spine surgery. To evaluate the changes in optimal PEEP in prone position throughout the surgical procedure. Methods: Observational study, one center. Main variable: optimal PEEP. Secondary variables: PaO2, pCO2 and dynamic compliance (Crd) in prone and supine position.
Ventilation management in paediatric anaesthesia remains difficult because of the wide range of age and weight, and therefore practices are heterogeneous. In adults, protective ventilation during anesthesia is now a standard of care but in children there is no level of evidence to recommend it. The aim of the study was to describe current practice and the factors associated with the use of high tidal volume during anaesthesia in children in France.
Our goal is to conduct a prospective, national, randomized-controlled, multicenter trial to investigate the effect of handover of anesthesia care on the occurrence of adverse outcomes in the perioperative period.
With population aging and limited resources, strategies to improve outcomes after surgery are ever more important. There is a limited understanding of what ranges of hemodynamic variables under anesthesia are associated with better outcomes. This retrospective cohort study will analyze how hemodynamic variables during surgeries predict mortality, morbidity, Intensive Care Unit admission, length of hospital stay, and hospital readmission. The use of machine learning in a large, broad surgery population dataset could detect new relationships and strategies that may inform current practice, and generate ideas for future research.
Comparison of clinical performance between LMA Protector Cuff Pilot and LMA Supreme in terms of oropharyngeal leak pressure, time to insertion, ease of gastric tube insertion, laryngeal view, incidence of sore throat
This work highlighted the beneficial role in terms of carers' satisfaction, quantity and quality of information transmitted.
Recently, a newly developed index, the Nociceptive Level (NOL) index, was validated and showed superiority over heart rate and blood pressure for recognition and grading of intense and mild nociceptive stimuli during surgery under general anesthesia. We hypothesize that compared with standard management, NOL-guided anesthesia will lead to reduced postoperative pain scores, and during anesthesia, to increased hemodynamic stability.
Patients receiving beach chair position shoulder surgery are vulnerable to perioperative cerebral desaturation, which is reported to be a risk factor for postoperative cognitive dysfunction. Investigators design this study to test the efficacy of perioperative goal-directed therapy in preventing cerebral desaturation and postoperative cognitive dysfunction in patients receiving beach chair position shoulder surgery.
