Effect of Dexmedetomidine on Postoperative Delirium After Awake Craniotomies
DexmedetomidineDelirium1 morePostoperative delirium (POD) is a common complication, and the incidence of POD ranges from 10% to 60%. Previous studies suggested that frontal approach and tumor located at the temporal lobe were independent risk factors for POD after supratentorial tumor resections. Therefore, patients undergoing awake craniotomies are high-risk populations for POD. A lot of trials show that dexmedetomidine might help to reduce the incidence of delirium in patients undergoing non-cardiac surgery. However, the impact of dexmedetomidine (DEX) on POD for patients undergoing awake craniotomies remains unclear. The purpose of this study was to investigate the effect of DEX on POD in patients undergoing awake craniotomies.
Inhalational Anesthesia vs. Intravenous Anesthesia
Neurocognitive DisordersAnesthesia2 moreTraditionally, general anesthesia is maintained with inhalational anesthesia (GAS), but there is a gap in knowledge regarding whether intravenous anesthesia (IV) can prevent deleterious postoperative outcomes in the geriatric surgical population. The goal of this clinical trial is to determine whether intravenous anesthesia (IV) leads to a decreased incidence of postoperative delirium (POD), postoperative cognitive dysfunction (POCD), and functional decline, and improved patient-reported outcomes (PROs) in older adults undergoing non-cardiac surgery when compared to the standard inhalational anesthesia (GAS). This single-center, 1:1 randomized, double-blind (patient & outcome assessor) clinical trial will compare inhalational vs. intravenous anesthesia on POD, POCD, functional status, patient-reported outcomes (PROs), and blood-based biomarkers in older patients undergoing elective, inpatient, non-cardiac surgery. Upon enrollment, 260 women and men ≥ 75 years undergoing elective noncardiac surgery under general anesthesia will be randomized to 2 groups: IV or GAS.

Postoperative DeliriumHemodynamic Instability2 moreIn the PATHFINDER 2 trial, the study investigators will test the intraoperative EEG-guided multimodal general anesthesia (MMGA) management strategy in combination with a postoperative protocolized analgesic approach to: reduce the incidence of perioperative neurocognitive dysfunction in cardiac surgical patients ensure hemodynamic stability and decrease use of vasopressors in the operating rooms reduce pain and opioid consumption postoperatively
The Effect of Desflurane Versus Sevoflurane Versus Propofol on Postoperative Delirium
Postoperative DeliriumMajor Noncardiac Surgery1 morePatients over the age of 65 years are at increased risk for developing delirium after noncardiac surgeries, resulting in increased morbidity and mortality. The prevention of postoperative delirium has been classified as a public health priority. However, so far data regarding possible intraoperative interventions to reduce the incidence of postoperative delirium is very scarce. Due to the more rapid wash-in and wash-out times of desflurane as compared to sevoflurane or propofol it seems reasonable that desflurane might be beneficial for the prevention of postoperative delirium. Therefore, we evaluate the effect of maintenance of anesthesia using desflurane, sevoflurane or propofol on postoperative delirium in elderly patients undergoing moderate- to high-risk major noncardiac surgery.
Effect of Ketamine/Midazolam Premedication Versus Pre-extubation Ketofol on Recovery Profile in...
Emergence DeliriumAn optimum recovery profile after AT includes a rapid, smooth awakening without emergence agitation (EA), stable vital signs and oxygenation, reduced postoperative nausea and vomiting (PONV), controlled postoperative pain, and patient or parents' satisfaction. Ketamine is a low-cost drug with a wide therapeutic window. Ketamine is a competitive N-methyl-D-aspartate receptor antagonist with good analgesic properties and periprocedural amnesia. The ketamine/midazolam combination was administered in different ways with controversial results about their effect on the EA and recovery profile. Ketofol, a mixture of ketamine and propofol, has been used in different favorable recovery profiles regarding postoperative EA and PONV. This study aims to evaluate the effect of premedication with an intramuscular ketamine/ midazolam combination versus pre-extubation ketofol on the EA and the recovery profile.
Methylene Blue and Postoperative Neurocognitive Disorders
Postoperative DeliriumPostoperative Cognitive DysfunctionPostoperative Neurocognitive Disorders are the most common neurological complications after major surgery, which are associated with higher increased mortality and morbidity in elderly patients undergoing major surgery. Until now highly effective intervention has not been established yet. Recent preclinical studies suggest mithochiondrial dysfunction may be linked to pathogensis of (postoperative delirium) POD and postoperative cognitive dysfunction (POCD). As Methylene blue(MB) is a mitochondrial protective agent and a safe drug with long history of clinical use, we propose that mitochondrial-targeted interventions may be useful to prevent POD/POCD in surgical patients.
Increasing Preoperative Cognitive Reserve to Prevent Postoperative Cognitive Dysfunction in Cardiac...
Postoperative Cognitive DeclinePostoperative Delirium1 morePostoperative delirium (POD) and postoperative cognitive decline (POCD) can be observed after cardiosurgical interventions. Taken together, these postoperative neurocognitive dysfunctions contribute to increased morbidity and mortality and higher economic costs. Preoperative risk factors of postoperative neurocognitive dysfunctions, such as decreased neuropsychometric performance or decreased cognitive daily activities, can be interpreted as reduced cognitive reserve. The aim of this study is to build up cognitive reserves to protect against the development of POD and POCD through preoperative, home-based, cognitive training.
WashIn /WashOut Procedure To Prevent Agitation During Recovery After Inhalational Anesthesia With...
AgitationEmergence2 moreInhalation anesthesia is the most frequently used technique and is performed in around 70% of surgeries worldwide. Sevoflurane is the most frequently used halogenated anesthetic and is used in 2/3 of the cases. The anesthetic strength of inhalation agents was established in the classic work of Eger and colleagues who determined the minimum alveolar concentration (MAC) of an inhaled anesthetic at atmospheric pressure, necessary to prevent a motor reaction in response to a pain stimulus in 50% of patients. Agitation is a frequent anesthesia complications and it not only lengthens the period of post anesthetic awakening and need for advance monitoring of the patient, but may be a predisposing factor in the development of postoperative delirium (POD) and postoperative cognitive dysfunction (POCD) which are independent predictors of increased mortality, prolonged treatment in the ICU and hospital, and prolonged social adaptation of the operated patients.(The ability of the patient to serve themselves independently.). There is a fairly popular point of view that there is no specific prophylaxis or treatment of postoperative agitation. However, a variant of anesthesia induction with sevoflurane was recently proposed, which reduced the frequency of agitation in children from 24.7% to 4.4%. The technique consisted in interrupting anesthesia at the moment of loss of consciousness, awakening the patient and subsequently performing re-induction. Since this technique might be time consuming in the busiest period of a surgical theatre and not safe if performed with the airways still unsecured it is advisable to shift the Wash In/Wash Out procedure to the stage of awakening at the end of surgery.
