Melatonin for Prevention of Postoperative Delirium After Lower Limb Fracture Surgery in Elderly...

Orthopedic Surgery

Postoperative delirium (POD) is one of the most frequent complications after surgery in elderly patients, affecting between 20 and 40% of patients older than 60 after major surgery. This complication has huge consequences for the patients, families and society: increase of morbidity and mortality, prolonged length of stay, cognitive and functional decline leading to loss of autonomy, and important additional healthcare costs. Among numerous risk factors identified, perioperative inflammatory stress is a key element in delirium genesis: surgical trauma releases danger signals in systemic circulation, activating immune cells and leading to neuroinflammation. Melatonin is a neurohormone regulating circadian rhythm. But it also exhibits antioxidant and free radical scavenger properties, and regulates energy metabolism and immune function. It has already demonstrated a neuroprotective potential in various animal models. Its use against delirium is promising: it decreases delirium incidence in elderly patients hospitalized in medical ward, and several studies are now recruiting in ICU. The hypothesis of the trial is that in a high-risk population, perioperative melatonin can reduce the incidence of POD. The main objective is to evaluate the effect of perioperative melatonin administration on postoperative delirium incidence in the first 10 days after surgery, in elderly patients (over 70 years old) being hospitalized and scheduled for acute surgery of fractured lower limb (from femoral head to tibial plateau). This is a prospective, national multicentric (24 centers), phase III, superiority, comparative randomized (1:1) double-blinded clinical trial with two parallel arms: Experimental group: melatonin 4mg per os every night, starting the evening before surgery (or 2 hours before emergency surgery) and until day 5 after surgery. Control group: placebo of this drug with the same schedule, during the same period of time. The patients are aged 70 or older, hospitalized and scheduled for surgery of a severe fracture of a lower limb (from femoral head to tibial plateau).

Acupuncture in Emergency Delirium After Tonsillectomy

Emergence Delirium

Emergence delirium (ED) (also called emergence agitation) can be defined as a "dissociated state of consciousness in which the child is irritable, uncompromising, uncooperative, incoherent and inconsolable crying, moaning, kicking or thrashing". Tonsillectomy (with or without adenoidectomy) is a routinely performed operation. Emergence agitation is a frequent phenomenon in children recovering from general anesthesia for tonsillectomy, and increases risk of self-injury. It's not unusual for the post-anesthesia care unit (PACU) staff look that a child, who was asleep just minutes before, starts screaming, pulling out his intravenous line, looks like he's about to fall out of his bed. This condition requires sedatives that may cause undesirable side effects. The cause of emergence delirium and the mechanism of agitation following general anesthesia is unknown. Probably the volatile agents work on some pathways, possibly in the locus coeruleus or amygdala, in the setting of a specific neurodevelopmental stage of the brain. While emergence delirium can be seen into adulthood, its peak incidence is in younger children (2-7 years of age). The incidence of ED is unclear: anywhere from 2-80%, but when confounders like pain, nausea etc. are controlled, the incidence is probably around 20-30%. Limited data suggest that acupuncture may be a safe, nonpharmacological treatment for the reduction of pain and agitation in term and preterm infants and that may be an alternative method for preventing ED. In particular a prospective, randomized, double-bind controlled study demonstrated a reduction of the ED in many surgeries, after the electrical stimulation of the heart 7 acupuncture site. Nearly 400 acupuncture points are known on the body surface and they belong to 14 meridians, running along the human body. After the needle peeling, the nervous free terminations release some polypeptid (the most important is the substantia P) and it increases the excitability of the near nervous free terminations which cause vasodilatation. It has a myorelaxant effect, decreases the level for pain tolerance and make stronger the inhibitor effect of descendent fibers, with production of endogenous endorphins. This is the reason why acupuncture is considered valid in prevention and control of ED.

Impact of Propofol Versus Sevoflurane on Incidence of Postoperative Delirium in Elderly Patients...

Delirium in Old AgeAnaesthetic

Postoperative delirium in older adults is a common and costly complication after surgery. Propofol and sevoflurane are commonly used anesthetics to maintain sedation during spine surgery, and have different sedative and anti-inflammatory effects. The aim of this trial will be compare the impact of propofol versus sevoflurane on incidence of postoperative delirium in elderly patients after spine surgery.

Efficacy of Erector Spinae Plane Block on Postoperative Delirium in Patients Undergoing Lumbar Spine...

Postoperative Delirium

Lumbar vertebra surgery is one of the most common surgical procedures.Delirium is common in geriatric patients after lumbar spinae surgery.postoperative delirium usually occurs in the early postoperative period and delays patient mobilization and thus lengthens hospital stay. The aim of this study was to investigate the effect of this field block on postoperative delirium in patients undergoing ESP with lomber vertebra surgery and with ultrasound guidance for postoperative analgesia.

MIND After Surgery

Post-operative DeliriumMajor Non-cardiac Surgery

Delirium is the most common neurological adverse outcome in elderly surgical patients. It is associated with an increased mortality and morbidity, including need for prolonged hospital stay and institutional care. Despite this, there are no effective preventive strategies. Melatonin is a hormone released from the pineal gland. It is used to improve sleep quality and to treat jet lag. Small studies have suggested that it can decrease the chances of delirium. Since the existing literature is small and uncertain, it is important to test its benefit in a large sample to help guide clinicians. This proposed trial is aimed at testing assessing the feasibility of a large, multi-center, randomized control trial to decrease the incidence of postoperative delirium.

Anesthesia Emergence Delirium

Emergence agitation (EA) is a post-operative behavioral disturbance was first reported in early 1960s. EA is a term used to describe non purposeful restlessness and agitation, thrashing, crying or moaning, disorientation and incoherence during early stage of recovering from general anesthesia in children, especially those receiving sevoflurane. Generally, the incidence of EA following sevoflurane anesthesia varies from 10% to 66% and is more common in pre-school children. EA is generally short lived without obvious aftereffect. However, it still accompanies with risk of self-injury, and requires extra nursing care, which may delay the discharge and increase the cost of medical care Emergence agitation is diagnosed by a final composite score of greater than or equal to 10 on the Pediatric Anesthesia Emergence Delirium Scale (PAED).(

Effect of Remimazolam and Propofol on Postoperative Delirium

Hip FracturesKnee Osteoarthritis1 more

Remimazolam is an ultra-short acting benzodiazepine agonist which is used widely for general anesthesia and sedation. Remimazolam has several advantages. Remimazolam is rapidly metabolized by tissue esterase that it does not accumulate even after infusion for long periods of time. The presence of reversal agents (flumazenil) is also advantageous. Also, hemodynamic stability compared to propofol gives clinicians preference to use for geriatric anesthesia. However, the study on the effect of remimazolam compared to propofol on postoperative delirium have not been carried out. The purpose of the study is to compare the incidence of postoperative delirium and recovery profile in elderly patients undergoing orthopedic surgery using either remimazolam or propofol.

Emergence Agitation

Pediatric patients undergoing tonsillectomy and adenoidectomy usually have a high incidence of postoperative EA, which increases the risk of developing postoperative airway obstruction and respiratory depression due to anatomical characteristics of operative location and increased susceptibility to opioid analgesics. the study will compare between nebulized and intravenous bolus of dexmedetomidine as a prophylaxis against postanesthetic emergence agitation in children undergoing tonsillectomy, adenoidectomy or adeno-tonsillectomy procedures.
