Active clinical trials for "Emergence Delirium"

The purpose of this study is to evaluate the use of intranasal dexmedetomidine to reduce the incidence of emergence delirium during general sevoflurane anesthesia in a pediatric population receiving pressure equalization tubes in one or more ear.

This will be a double blind, placebo-controlled study of patients ≥65 years of age undergoing surgery of the spine, hips and knees replacement at the University of California, San Francisco (UCSF) Medical Center. Intraoperative anesthetic and postoperative pain management will be standardized. Patients will be randomized to receive either placebo or gabapentin preoperatively, and continued postoperatively until discharge. Intraoperative anesthetic and other postoperative pain management strategies will be standardized. Postoperative delirium will be measured using structured interviews. Cognitive function will be measured using a battery of neurocognitive tests pre- and post-operatively. Using an intention to treat strategy, we, the researchers at UCSF, will compare the incidence of postoperative delirium and cognitive dysfunction, the amount of postoperative pain, and narcotic requirements between the two groups. The primary outcome will be postoperative delirium. Secondary outcomes will be postoperative pain and opioids use, and length of hospital stay, and cognitive dysfunction.

This is a randomized study to examine whether aerobic exercise training (AET) before total shoulder replacement (TSR) surgery reduces the incidence of post-operative delirium (POD) and shorten time to recovery in elderly patients. POD is a form of sudden change in mental function that can be experienced after undergoing surgery.

This study aims to determine whether, compared with placebo, the nighttime administration of a intravenous dexmedetomidine is effective at inducing sleep and preventing postoperative delirium in extubated post-cardiac surgical patients.

Patients undergoing cardiac surgery were recruited. Baseline characteristics of all subjects were collected. The 3-minute Delirium diagnostic Scale (3D-CAM) was used to screen the POD group and non-POD group from the recruited subjects during the first 7 days after surgery. Peripheral blood samples were collected 1 day before surgery and 2 day after surgery. . Plasma was isolated from peripheral blood for subsequent proteomic analysis.

Postoperative delirium is commonly observed in elderly patients in the postanesthesia care unit (PACU) and during the first 2-3 days following surgical procedures. This is an important clinical problem in the geriatric surgical patient; morbidity and mortality rates are significantly higher in patients who develop delirium. At the present time, the etiology of delirium has not been precisely defined. However, studies suggest that inflammation related to the surgical stress response is an important contributing factor in inducing neuroinflammation and subsequent cognitive dysfunction and delirium. Therefore it is possible that agents which attenuate perioperative inflammation may reduce the risk of the development of delirium following surgery. Dexamethasone is a potent corticosteroid that is used by anesthesiologists primarily as an antiemetic agent. Small doses of dexamethasone have also been demonstrated to significantly reduce the release of inflammatory markers after surgery. The anti-inflammatory effects of corticosteroids have the potential to beneficially impact neuroinflammation and the risk of developing postoperative delirium. The aim of this randomized, controlled, double-blinded investigation is to determine if dexamethasone, administered at induction of anesthesia, can decrease the incidence of delirium at the time of discharge from the PACU and during the first 2 days following surgery.

Elderly patients who undergo anesthesia and non-cardiac surgery are subject to deterioration of brain function including the development of postoperative delirium (PD) and postoperative cognitive dysfunction (POCD). These disorders cause disability, distress for both patients and their families, are associated with other medical complications and account for significant additional health care costs. We currently use relatively primitive approaches to preventing and treating PD and POCD. Dexmedetomidine is a drug used for sedation in critically ill patients that provides some pain relief and controls the bodies response to stress. The sedation produced by dexmedetomidine appears more similar to natural sleep than any other drug used for anesthesia and postoperative sedation. Data suggesting that dexmedetomidine can prevent delirium following cardiac surgery and the developing understanding of the causes of PD and POCD suggest that dexmedetomidine will be particularly effective.

The purpose of this study is to compare the incidence of EA in pediatric patients undergoing minor ENT surgery under Sevoflurane and compare opioid-only based intra-operative analgesia to multi-modal analgesia consisting of opioid and IV acetaminophen or PO acetaminophen regimen using a validated and standardized EA measurement tool, the Pediatric Anesthesia Emergence Delirium (PAED) scale. The post operative pain scores will be measured in all patients by post-op recovery staff using FLACC Score/Wong-Baker FACES (patients 24 months up to 7 years of age) or Numeric Pain Score for patients 7 years of age. The pre-operative, surgery, anesthesia and post-operative staff will be all blinded.

The aim of this study is to compare the efficacy of mother's recorded voice versus dexmedetomidine injection on postoperative agitation in children undergoing elective surgery.

In the last two decades, viral infections have increased dramatically : the 2003 severe acute respiratory syndrome coronavirus outbreak, the 2009 swine flu pandemic, the 2012 Middle East respiratory syndrome coronavirus outbreak, the 2013-2016 Ebola virus disease epidemic in West Africa and the 2015 Zika virus disease epidemic and not least the COVID-19 pandemic. At the same time, neurological disorders are a major and increasing global health challenge, which accounts for a substantial portion of the disease burden worldwide . In Europe, more than half of the population (approx. 60% ) suffers from a neurological disease, ranking number three among all disease groups . The figures are higher in the population with more than 65 years. Based on Eurostat annual publication "Aging Europe", in 2020 people over 65 represented 20.6% of the European Union population, and the projections show that the share of people over 65 is expected to strongly increase until 2058, reaching 30.3% of the EU population. Furthermore, while in civil aviation, the mortality rate is estimated around 0,00525% (Eurocontrol, 2022), the perioperative mortality rate in Europe is about 4% (Pearse et al., 2012). Clearly, the patients undergoing surgery already have a higher mortality risk depending on their initial medical conditions. However, the medical field can without doubts benefit from an improved risks assessment approach derived from the civil aviation. Against this backdrop, the project aims at: i) researching the correlation between a neurotoxic viruses' infection and the increased risk, in terms of frequency or severity, of developing a cognitive disfunction such as the postoperative cognitive dysfunction (POCD), by conducting an observational clinical trial on selected neurotoxic viruses (SARS-CoV-2, Herpes simplex virus, Cytomegalovirus and Epstein Barr virus). ii) developing a theoretical model for monitoring the implications of general anaesthesia in elder patients aged ≥ 65 years iii) designing a risk assessment mechanism, based on the best practices developed in the aerospace sector, for patients with neurotoxic infection and POCD, that can be furtherly scalable in other medical contexts. iv) building an AI-based platform, following the example of the NSQIP risk calculator for cardiovascular postoperative complications, both for data collection and data processing, able to return an estimate of the risk of perioperative-related cognitive complications in elder patients undergoing major elective surgeries. Observational Clinical Trial The clinical trial will recruit a sample of 1685 patients in eight centres (about 250 patients per centre, considering also the drop-out rate) to be finalised in 24 months. The primary end point of the clinical trial is to evaluate if patients undergoing general anaesthesia for elective major surgeries lasting longer than 1 hour that have an history of COVID-19 (not an active SARS-CoV-2 infection) do have a higher risk to develop postoperative cognitive dysfunction (POCD)/delayed neurocognitive recovery (DNC) at 3 months and 6 months follow up after surgery. Secondary end point include: - Relationship between POCD/DNC with preoperative exposure to other neurotropic viruses: Herpes simplex virus (HS), Cytomegalovirus (CMV), and Epstein Barr virus (EBV). - Development -on the basis of collected data- of a software dedicated to calculating in the preoperative phase the risk for early postoperative delirium or POCD/PNDs. - Development of a conceptual model of "perioperative safety management": as in civil aviation traffic control, increasing the patients' perception of healthcare safety and quality. - Delivery of training to healthcare practitioners concerning the preoperative evaluation of POD risk and the identification of patients at risk.
