Can Caudal Dexmedetomidine Prevents Sevoflurane Induced Emergence Agitation in Children
Delayed Emergence From AnesthesiaEmergence agitation (EA) is common phenomenon in pediatric patients undergoing general anesthesia by inhalation agents. The incidence of EA was reported to range from 18% to 80%. Sevoflurane now is the inhalational anesthetic agent of choice for pediatrics, Different strategies have been suggested to decrease the incidence and severity of EA. No gold standard technique for treating EA after sevoflurane anesthesia is currently available. The main question is can caudal dexmedetomidine be used for this purpose?
Postoperative Delirium: EEG Markers of Sleep and Wakefulness
Postoperative DeliriumPostoperative delirium is a condition in which patients develop temporary difficulties in maintaining attention and thinking clearly. These new problems can appear after surgery and change throughout the day. This confusion can last several days. The overall purpose of this study is to measure brain activity during sleep and wakefulness to learn about their relationships to delirium after surgery. While participants may not feel like their normal self during the study, they are in the best position to help us learn how to improve the recovery of brain function and sleep in others having surgery. The investigators need to learn from those who have and have not become confused after their surgical procedure.
Deep Neuromuscular Block on Cytokines Release and Postoperative Delirium
Hip FracturesThe purpose of the study is to determine the relationship between the degree of neuromuscular block, the release of cytokines and clinical outcomes in elderly patients undergoing orthopedic surgery. Investigators hypothesize that deep neuromuscular blockade decreases the release of cytokine and the incidence of postoperative delirium in elderly patients undergoing orthopedic surgery, compared with moderate neuromuscular blockade.
Shaping Anesthetic Techniques to Reduce Post-operative Delirium
DeliriumLumbar Radiculopathy2 moreThe purpose of this study is to determine if light sedation with spinal anesthesia reduces the incidence of delirium compared to receiving general anesthesia during spinal surgery in older adults.
Dexmedetomidine Combined With Ropivacaine for Postoperative Continuous Femoral Nerve Block
ElderlyKnee Arthroplasty4 moreDelirium is common in the elderly after orthopedic surgery and is associated with worse outcomes. Continuous femoral nerve block is frequently used for postoperative analgesia after total knee arthoplasty. The investigators hypothesize that dexmedetomidine, when combined with ropivacaine for continuous femoral nerve block, can reduce the incidence of delirium and improve the long-term outcome in elderly patients after total knee arthroplasty.
Risk Factor of POD and POCD After Cardiac Surgery
Postoperative DeliriumPostoperative Cognitive DysfunctionPostoperative delirium (POD) and postoperative cognitive decline (POCD) are common after surgeries in the elderly, especially after cardiothoracic surgery. These conditions are associated with adverse short- and long-term outcomes. Multiple conditions in the perioperative period have been proposed as risk factors of POD and POCD. Incidences vary across institutions due to differences in screening and diagnostic tools.
Emergence Delirium in Children: Total Intravenous Anesthesia With Propofol and Remifentanil Versus...
Emergence DeliriumEmergence delirium (ED) refers to a wide variety of behavioural disturbances that are commonly seen in children following emergence from anesthesia. ED can potentially be dangerous and have serious consequences for the child such as injury, increased pain, and dislodgement of medical devices, often requiring physical restraint or pharmacological control. Witnessing this behaviour can be stressful for parents, which can negatively affect their interaction with the healthcare system, and their relationship with the child, nursing staff and other healthcare providers. The investigators aim to minimize ED to reduce the distress experienced by patients and their parents. This study will compare the recovery profile of sevoflurane with that of propofol remifentanil and their associated incidence of ED. This study should enable us to determine which form of anesthesia is associated with the fewest incidences of ED in children.
Use of Dexmedetomidine to Reduce Emergence Delirium Incident in Children
AgitationAnesthesia1 moreEmergence delirium (ED) from general anesthesia posts risk and harm to pediatric population undergo general anesthesia. The purpose of the study is to compare the use of dexmedetomidine versus placebo in reducing the incidence and severity of ED in a pediatric neurosurgical population.
Effect of Dexmedetomidine on Emergence Agitation in Children With or Without Tube Insertion Under...
MyringotomyThe investigators are inviting your child to participate in this research study because your child is having myringotomy (putting a tiny incision in the eardrum with or without tube insertion) under general anesthesia. The purpose of this study is to determine whether a single injection of Dexmedetomidine (study medication) decreases the frequency of awaking from anesthesia frightened or agitated in children having myringotomy surgery as compared to those children who receive placebo (sterile saltwater).
Dexmedetomidine and IV Acetaminophen for the Prevention of Postoperative Delirium Following Cardiac...
DeliriumInvestigators will assess the incidence and duration of postoperative delirium in patients ≥60 years old undergoing coronary artery bypass grafting (CABG), with/without valve surgery (aortic and/or mitral) based on different regimens for postoperative sedation and analgesia. Patients will receive either intravenous (IV) dexmedetomidine and IV acetaminophen or standard postoperative management using IV propofol with morphine or hydromorphone. The Confusion Assessment Method (CAM) will be used to assess delirium in these patients. Investigators also seek to compare postoperative (48 hours) analgesic requirements in patients with or without IV acetaminophen. Investigators will finally assess postoperative cognition in post-surgical patients up to one year post-discharge using a cognitive assessment scale.
