MELAtonin for Prevention of Postoperative Agitation and Emergence Delirium in Children

Emergence Delirium

Postoperative agitation and emergence delirium describe a spectrum of symptoms of early postoperative negative behavior, in which the child experiences a variety of behavioral disturbances including crying, thrashing, and disorientation during early awakening from anaesthesia. The symptoms are common with a reported incidence of approximately 25%. Some clinical trials have studied the effect of prophylactic oral melatonin for reducing the risk of emergence agitation in children, some finding a considerable dose-response effect. Melatonin has a low bio-availability of approximately 15 %. The safety of exogenous melatonin for pediatric patients has been studied with no apparent serious adverse effects, even at repeated short-term use of high doses of intravenous melatonin. The aim of this clinical trial is to investigate the prophylactic effects and safety of intravenous melatonin administered intraoperatively for prevention of postopreative agitation and emergence delirium in children after an elective surgical procedure. The study is designed as a randomised, double-blind, placebo-controlled clinical trial.

Non-pharmacological Prevention of POD in Frailty Elderly Undergoing Elective Surgery Applied by...

Frail Elderly SyndromePrimary Prevention2 more

The increase in the population over 60 years of age who could receive surgery due to changes in life expectancy and advances in surgical and anesthetic techniques. Likewise, elderly people (EP) may have a higher risk of postoperative morbidity and mortality compared to young people, with frailty being one of the risk factors that increases adverse outcomes in this period and increases the probability of developing syndromes such as postoperative delirium (POD). Assessment of frailty in EP prior to surgery is not routine, so it is unknown how many frail and/or pre-frail EP undergo surgery in health care systems. There is an association between being frail and developing greater delirium and/or postoperative cognitive deficit, which in summary translates into an increase in perioperative morbidity and mortality. For the prevention of POD, there are pharmacological and non-pharmacological measures that seek to promote orientation with respect to their environment and make it as familiar as possible, stimulate early aspects of memory and thinking skills, as well as promote sleep using environmental hygiene measures. In Chile, protocols of non-pharmacological measures have been proposed by occupational therapy teams, which have had positive results in reducing POD in frail elderly patients. These measures are temporal-spatial reorientation, physical mobilization, correction of sensory deficits, environmental management, sleep protocol, and reduction of anticholinergic drugs with statistically significant results in the reduction of POD. In accordance with the above, the objective of this study is to evaluate the impact of non-pharmacological measures applied by the nursing team in reducing the incidence of POD during the post-surgical period in fragile and pre-fragile EP undergoing elective non-cardiac surgeries. It is expected that in the end, frail and pre-frail EP who receive non-pharmacological interventions by the nursing team will present a lower incidence of POD at 24 hours compared to those who receive traditional care.

Anaesthetic Depth and Short Term Delirium Post Cardiac Surgery Intervention

Post-operative DeliriumAnaesthetic Depth

Postoperative delirium (POD) is a critical complication of major surgery and affects up to 70% of surgical patients over the age of 60 years. The additional healthcare costs associated with delirium exceed €50,000 per patient per year due to prolonged hospital stay, increased risk of long-term care or institutionalization, and the risk of developing dementia or cognitive impairment . Therefore, prevention of POD is a major goal in the perioperative setting. The investigator proposes this randomized study to evaluate the interest of a reduced anesthetic depth to prevent short-term cognitive disorders after cardiac surgery in elderly subjects. Method: Patients over 75 years old scheduled to undergo one of the cardiac surgeries of interest (valvular, coronary bypass, aortic or combined surgery) will be randomized to 2 paralell arms : Perioperative anesthesia with a BIS (Bispectral index) target of 35 Perioperative anesthesia with a BIS(Bispectral index) target of 55 The presence of mental confusion will be determined by CAM-ICU ( Confusion Assessment Method for the ICU ) at day 3 post procedure. Ancillary study: To assess cognitive status at inclusion, discharge and third post operative month using the MOCA(Montreal Cognitive Assessment ). Conclusion:The hypothesis of this study is that a lower depth of anesthesia will reduce post operative delirium in the first three days in patients older than 75 years who are planned for valvular, coronary artery bypass, aortic or combined cardiac surgery .

Dexmetomedine for Post Operative Delirium in Elderly Patients Undergoing Elective Total Knee Replacement...

Postoperative Delirium is a Geriatric

Postoperative delirium is a geriatric syndrome occurring after anesthesia and surgery which manifests as acute alterations in mental status, involving changes in cognition, attention, and levels of consciousness that tend to fluctuate The use of dexmedetomidine with the intention to prevent postoperative delirium remains controversial. Where it has shown to be effective in older adult patients undergoing cardiovascular and non-cardiovascular surgeries

Effect of Intranasal Insulin on POCD and POD

DeliriumHeart Diseases

Decline in cognitive function after surgery occurs most commonly in older patients and patients undergoing major surgeries, such as heart surgery. Postoperative Cognitive Dysfunction (POCD) may last a prolonged period of time while Postoperative Delirium (POD) is a more acute disturbance in attention, awareness and cognition. The cause of POCD and POD are not fully understood, however some of the pathophysiology of POCD is similar to that of Alzheimer's disease (AD). Insulin given intravenously during heart surgery has been shown to preserve short and long-term memory function after the operation. Clinical trials further demonstrated that insulin given via the nose (intranasal) improves memory performance of patients with AD or cognitive impairment suggests that intranasal insulin also could be a therapeutic option for POCD and POD. This study is designed to examine the effect intranasal insulin on POCD and POD. The goal is to investigate whether administration of intranasal insulin during and after heart surgery improves cognitive function postoperatively.

Post-Stroke Enhancement of Delirium Outcomes With Reduction in Neuro-checks

StrokeAcute4 more

There have been limited studies on delirium in patients hospitalized with acute stroke. There have been no studies on the potential impact of overnight neuro-checks and resulting sleep disruption on delirium or other outcomes. Additional research is needed to determine if overnight checks are necessary or even harmful. We aim to find out if stopping overnight neuro checks may prevent delirium and benefit the patient.

Effects of Perioperative Transauricular Vagus Nerve Electrical Stimulation on POD, POCD and CPSP...

Postoperative Cognitive DysfunctionPostoperative Delirium1 more

Postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) occur in 11-51% of patients after surgery, and its prevalence increases with age. The occurrence of delirium is associated with increased morbidity and mortality, prolonged hospital stay, worse functional recovery. Orthopedic procedures and specifically joint replacements have been considered as a major risk for development of chronic postsurgical pain (CPSP). Approximately 13-44% of patients will develop CPSP after knee or hip arthOpioid abuseroplasty. CPSP may cause the discomfort, distress, disability and opioid abuse. Mounting evidence has revealed that inflammation triggered by surgical trauma plays a key role in POD, POCD and CPSP. Recent studies found that vagus nerve stimulation showed the suppression of inflammation. In this study, the effect of perioperative transauricular vagus nerve stimulation on the prognosis of patients undergoing arthroplasty will be investigated, providing potential solutions for the prevention and treatment of postoperative cognitive dysfunction, postoperative delirium and chronic postsurgical pain.
