The investigators would like to determine if using Dexmedetomidine alone or in a reduced dose can prevent or reduce the incidence of adverse effects, while providing adequate sedation, and respiratory stability as compared to propofol.
This is a pilot study to determine if a standard bolus dose and infusion of dexmedetomidine can significantly decrease the dose of propofol (infusion) required for accomplishing an MRI.
The purpose of this study is to determine pharmacodynamic interactions of propofol and dexmedetomidine,exploring the effect of dexmedetomidine on propofol unconsciousness median effective concentration (EC50).
This is a single-blind randomized clinical trial. Patients undergoing abdominal surgery will be enrolled and randomly divided into two groups: dexmedetomidine group and propofol group. In the dexmedetomidine group, patients will receive continuous intravenous infusion of dexmedetomidine (infusion dosage range: 0.1 ~ 0.7 mcg/kg/h). In the propofol group, patients will receive continuous intravenous infusion of propofol (infusion dosage range: 0.3 ~ 1.6 mg/kg/h). Hemodynamics wil...
This study is designed to explore the possible effects of dexmedetomidine infusion on sublingual microcirculation in patients undergoing on-pump coronary artery bypass graft surgery
studying the effect of adding dexmedetomidine intravenous infusion to propofol intravenous infusion during sedation for drug induced sleep endoscopy
The purpose of this study is to determine the effect of gender on pharmacodynamic interaction of propofol and dexmedetomidine, exploring the effect of gender on propofol unconsciousness median effective concentration with different dose dexmedetomidine.
Before anethetic induction, infuse dexmedetomidine 0.5 mcg/kg for 2 minutes and after injection of lidocaine 30 mg, propofol infusion by using target controlled infusion (TCI) pump. Effect site concentraion of propofol start from 5 and changes the concentration as previous response to i-gel insertion as up and down methods
Under the hypothesis that dexmedetomidine sedation would result in less respiratory distress, the investigators evaluated the sleep cycle, respiratory pattern, and adverse respiratory events using Watch PAT 200 in surgical patients who received different intraoperative sedatives, dexmedetomidine and propofol.
Emergence agitation/delirium (EA/ED) is a common complication in pediatric surgery patients, which increases the risk of developing postoperative airway obstruction and respiratory depression. In infants, there is a high incidence of emergence agitation (EA) after desoflurane anesthesia. The aim of the present preliminary study was to determine the safety and efficacy of of intraoperative infusion of dexmedetomidine (DEX) that would prevent postoperative EA and ED in children u...
An ideal sedative for colonoscopy should have properties that include: rapid onset and offset of action, provide cardiopulmonary stability, have minimal adverse effects, and allow for smooth recovery, and early discharge. Propofol is often used solely because of its rapid onset and short duration of action---a property which is ideal for a fast recovery and early discharge in the ambulatory setting. However, the use of propofol has been associated with undesirable effects such ...
Sixty patients were randomly allocated into two groups, group PD and group PR, thirty patients in each group. Patients in PD group received propofol and dexmedetomidine intravenous infusion and patients in PR group received propofol and remifentanil intravenous infusion. Sedation score and patients' satisfaction, surgeon satisfaction, heart rate, mean arterial blood pressure, oxygen saturation, and side effects such as respiratory depression, nausea, vomiting, airway obstructio...
Serial transcranial Doppler (TCD) exams in healthy volunteers and in animal models showed a strong linear relationship between middle cerebral artery (MCA) flow velocity (FV) and dexmedetomidine infusion. The concomitant elevation of pulsatility index (PI) indicates vasoconstriction of the cerebral vasculature as the most profound underlying mechanism.
The primary purpose of this observational study is to compare what drugs work best in sedating children (> 3 months to < 36 months) who need an MRI. This type of research may help clinicians (healthcare providers) learn more about how dexmedetomidine works compared to propofol. The investigators are planning to have 60 children complete the study at Children's Healthcare of Atlanta at Scottish Rite. Half (30) of the patients will be randomized to receive dexmedetomidine and the...
The purpose of this study is to determine whether the use of dexmedetomidine, a selective α2-adrenergic receptor agonist with sedative, analgesic, and antinociceptive properties, would be associated with a lower incidence of delirium when compared to propofol and midazolam. We hypothesize that sedation with dexmedetomidine following cardiac surgery with CPB will be associated with a lower incidence of postoperative delirium.
MRI though not painful requires deep sedation for children due to the loud noise created. With deep sedation comes respiratory depression so the interest in Dexmedetomidine. For standardization MRI brain was chosen and also for the fact that patients usually have history of convulsions where drugs like ketamine may not be a good option. Patients were recruited after ethics committee approval. After pre-medication with intranasal midazolam 0.2 mg/kg body weight, Intravenous acce...
Patients in the ICU who need help with their breathing are put onto a machine called a ventilator and are also given a medicine, called a sedative, which helps them to sleep and makes them more comfortable. Propofol is a sedative that is routinely used for these purposes. For most patients the aim of sedation is to make them sleepy but still able to respond to nursing staff (light sedation). Dexmedetomidine is a new sedative for use in intensive care and in this clinica...
Patients undergoing lower extremity surgery with spinal anesthesia are often sedated to reduce patient discomfort due to large noises during surgery and also to reduce anxiety. Most commonly used sedatives include propofol and midazolam, but these agents are known to often cause hypotension or respiratory depression. Dexmedetomidine is a selective alpha 2 adrenergic drug, which acts as a sedative and also has analgesia effects. In contrast to propofol or midazolam, dexmedetomid...
This is a randomized controlled trial to compare propofol to dexmedetomidine for prolonged sedation (> 24 hours) in critically ill patients who require mechanical ventilation.
Recovery of hunger is a source of comfort for patients after general anesthesia. Moreover, this aspect of post-operative period is often required for discharging patients from hospital after ambulatory surgery. Indeed, this item is part of a multi-parameter score (Chung score) whose validation evaluates patient's ability to return home. The impact of anesthetics on hunger is largely unknown but few studies suggest an orexigenic effect of propofol compared to halogenated gases...
Dexmedetomidine, a central and peripheral α2-receptor agonist distinct from GABA receptor for benzodiazepines and propofol, has been approved by the US Food and Drug Administration only for use up to 24 h in mechanically ventilated patients. The investigators aim to compare dexmedetomidine with propofol for sedation >24h in poly traumatized mechanically ventilated patients.
Dexmedetomidine, was reported to prevent postoperative delirium in elderly patients following its use in intensive care units. Possible mechanisms included improved quality of sleep and an inhibitory effect on inflammation. A greater number of studies indicated that propofol has negative effect on postoperative cognitive function. In this study, we planned to investigate the influence of these two different sedative drugs on peripheral inflammation induced by surgery and postop...
Dexmedetomidine, a selective alpha-2 agonist agent used for maintaining sedation in intensive care patients in receipt of mechanical ventilation, is being increasingly utilized in anaesthesia practice for facilitating anaesthesia depth as an adjunct to base anaesthetics (intravenous; propofol: inhalational; sevoflurane, desflurane). The investigators intend to assess the anaesthetic potential of dexmedetomidine in controlled anaesthesia settings empowered by the use of an objec...
In our randomized study, we aim to test the hypothesis that the reinstitution of a normal circadian rhythm by continuous infusions of dexmedetomidine compared to propofol between 8pm and 6am after diagnosis of hyperactive or mixed delirium, decreases the duration of delirium. The infusions might have to be repeated several times to achieve resolution of delirium.
Patients undergoing total knee arthroplasty with spinal anesthesia are often sedated to reduce patient discomfort due to large noises during surgery and also to reduce anxiety. Most commonly used sedatives include propofol and midazolam, but these agents often cause hypotension or respiratory depression, especially in elderly patients. Dexmedetomidine is a selective alpha 2 adrenergic drug, which acts as a sedative and also has analgesia effects. In contrast to propofol or mida...
