Filter by:As an invasive operation, gastroscopy will cause children's nervousness, anxiety and uncooperative behavior, and even lead to the risk of bleeding and perforation, which will also affect the accuracy of the examination results.The purpose of this study is to explore the influence of different doses of esketamine on the induced dose ED95 of remazolam during gastroscopic placement in children, and to provide theoretical basis for the combined use of remimazolam besylate and esketamine in gastroscopic anesthesia in children.
Regional anesthesia is a common clinical anesthesia method, and regional anesthesia-assisted sedation play a central role in promoting patient comfort and relieving anxiety. With increasing age, elderly people experience changes in pharmacokinetics and pharmacodynamics and increased drug sensitivity. Ciprofol has advantages in adverse events such as hypotension and respiratory depression. There are fewer studies on the recommended dosage of ciprofol-assisted sedation for intrathecal anesthesia in elderly patients. The aim of study is to identify the 95% effective dose of ciprofol-assisted sedation in elderly patients undergoing spinal anesthesia using a biased coin design up-and-down sequential method(BCD-UDM)
Due to the incomplete development of systems and low pain thresholds in the pediatric population, good general anesthesia is required during the perioperative period to ensure the smooth progress of the surgery.Propofol is often used for anesthesia induction in clinical work, which can achieve good anesthesia effects. However, this drug has obvious injection pain and is prone to significant inhibition of blood circulation, and may even lead to adverse conditions such as respiratory depression in children. For the pediatric population, maintaining appropriate anesthesia depth and stable circulation during the induction period of general anesthesia has always been a focus of attention and research by anesthesiologists.Remimazolam besylate is a new type of water-soluble ultra short acting benzodiazepine drug that is hydrolyzed and metabolized by plasma esterase in the body, independent of liver and kidney function, and the metabolite zolam propionic acid has no pharmacological activity; Rapid onset and failure, short sedation recovery time; Has little impact on respiration and circulation; And there is no injection pain.Remazolam besylate is highly suitable for children due to its characteristics, and some studies have demonstrated the safety of intravenous injection of Remazolam besylate. However, there is limited research on its dosage exploration, which to some extent limits its clinical application in children.This study aims to explore the 95% effective dose (ED95) of single intravenous injection of remidazolam besylate in children of different age groups, providing a theoretical basis for the use of remidazolam besylate in pediatric anesthesia.
Fast-track Surgery (FTS ) refers to the application of various proven effective methods in perioperative period to reduce stress and complications and accelerate the recovery of patients.Nowadays, FTS has been successfully applied in clinical practice."FTS" truly embodies the concept of "patient-centered" and the direction of medical development. Lower limb joint damage (the meniscus, and patellar ligament, etc.) is the joint movement orthopedic common disease, often characterized by joint swelling, pain, sports relaxation instability, thigh muscle atrophy, most can't continue to pursue the original movement, even unbend and flexor limited activity, result in patients with walking difficulties, serious impact on the patient's quality of life.Practice has proved that minimally invasive surgery under arthroscopy is the best way to treat such injuries. According to literature reports, the average hospital stay after arthroscopy is 5~7 days, while successful application of FTS can shorten it to 2~3 days. Anesthesia plays an important role in the process of FTS.Compared with general anesthesia, intra-spinal anesthesia can effectively reduce the incidence of postoperative complications in patients, such as ventilator-related lung injury, deep vein thrombosis, cardiovascular and cerebrovascular accidents, and acute renal failure.Ropivacaine is a long-acting amide local anesthetic. Compared with bupivacaine, it is more and more widely used in spinal anesthesia due to its advantages of lower degree of motor nerve block and weaker toxicity to central nervous system and cardiac.However, the optimal dosage of ropivacaine for arthroscopic surgery is still unclear. Conventional dosage makes patients unable to move 2-4h after surgery and unable to urinate autonomically. Therefore, this study aims to optimize the dosage of ropivacaine for spinal anesthesia and enable patients to recover motor function at an early stage.
