Electroencephalographic Arousal Patterns Under Dexmedetomidine Sedation.

The depth of dexmedetomidine-induced sedation is difficult to assess without arousing the patient. We evaluated frontal electroencephalogram (EEG) as an objective measure of dexmedetomidine-induced sedation. Our aims were to characterize the response patterns of EEG during a wide range of dexmedetomidine-induced sedation and to determine which spectral power best correlated with assessed levels of dexmedetomidine-induced sedation.

Dexmedetomidine and Midazolam Sedation Reduces Unexpected Patient Movement During Dental Surgery Compared With Propofol and Midazolam Sedation.

Owing to its unpredictability, unexpected patient movement is one of the most important problems during surgery while under monitored anesthesia care with sedation. The purpose of this study was to compare unexpected patient movement during dental surgery while under dexmedetomidine and propofol sedation.

Comparison of sedation with dexmedetomidine vs propofol during hysteroscopic surgery: Single-centre randomized controlled trial.

The most appropriate sedative agent for conscious sedation in minor hysteroscopic surgeries is still unclear. Dexmedetomidine a sedative and analgesic agent, may be appropriate for outpatient procedures. The aim of our study was to compare the sedative, analgesic and hemodynamic effects of dexmedetomidine vs propofol in combination with fentanyl and midazolam in patients undergoing minor hysteroscopy surgery.

OBJECTIVE To compare sedation in cockatiels (Nymphicus hollandicus) after intranasal administration of midazolam and midazolam-butorphanol. ANIMALS 9 healthy adult cockatiels. PROCEDURES A randomized, controlled, blinded, complete crossover study was conducted. Birds were assigned to 3 treatment groups. Midazolam (3 mg/kg), midazolam-butorphanol (3 mg/kg for each drug), or sterile saline (0.9% NaCl) solution (control treatment) was administered intranasally. Sedation quality was assessed at 3 time points by...

Different effects of propofol and dexmedetomidine sedation on electroencephalogram patterns: Wakefulness, moderate sedation, deep sedation and recovery.

Sedation induces changes in electroencephalography (EEG) dynamics. However, the distinct EEG dynamic characteristics at comparable sedation levels have not been well studied, resulting in potential interpretation errors in EEG monitoring during sedation. We aimed to analyze the EEG dynamics of dexmedetomidine and propofol at comparable sedation levels and to explore EEG changes with increased sedation levels for each agent. We measured the Bispectral Index (BIS) and 20-channel EEG under dexmedetomidine and ...

The relationship of heart rate between natural sleep and dexmedetomidine sedation.

Sedation by dexmedetomidine is similar to natural sleep and often causes bradycardia. We attempted to determine the relationship of heart rate changes between natural sleep and dexmedetomidine sedation.

A randomized controlled trial of oral chloral hydrate vs intranasal dexmedetomidine plus buccal midazolam for auditory brainstem response testing in children.

Moderate to deep sedation is required for an auditory brainstem response test when high-intensity stimulation is used. Chloral hydrate is the most commonly used sedative, whereas intranasal dexmedetomidine is increasingly used in pediatric non-painful procedural sedations.

Midazolam is effective to reduce cortical network activity in organotypic cultures during severe cholinergic overstimulation with soman.

Intoxication with organophosphorus compounds can result in life-threatening organ dysfunction and refractory seizures. Sedation or hypnosis is essential to facilitate mechanical ventilation and control seizure activity. The range of indications for midazolam includes both hypnosis and seizure control. Since benzodiazepines cause sedation and hypnosis by dampening neuronal activity of the cerebral cortex, we investigated the drug's effect on action potential firing of cortical neurons in brain slices. Extens...

Oxygen Saturation and Pulse Rate Change in Children during Sedation with Oral Midazolam and Nitrous Oxide.

We aimed to examine if changes in oxygen saturation and pulse rate of pediatric patients during conscious sedation with midazolam and nitrous oxide are associated with child's behavior, midazolam dose, the type and duration of the treatment and demographic parameters.

Intravenous versus Subcutaneous Midazolam Using Jet-injector in Pediatric Sedation; a Randomized Clinical Trial.

Conscious sedation with midazolam intravenously for a patient with Parkinson's disease and unpredictable chorea-like dyskinesia.

Oral surgery can be difficult in patients with chorea-like dyskinesia, which is common in those on long-term levodopa medication for Parkinson's disease, and we know of no conclusive evidence to indicate whether conscious sedation with midazolam is effective in such cases. We report a patient in whom levodopa-induced chorea-like dyskinesia disappeared when midazolam was given intravenously for conscious sedation.

This retrospective study investigated the application of the sedation-agitation scale (SAS) in pediatric bronchoscopy by observing its effects on sedative dosages and adverse reactions.Children who underwent sedation before bronchoscopy, during the period from January 2014 to June 2017, were divided into control and SAS groups. Patients in the control group were administered a single dose of 0.1 to 0.3 mg/kg midazolam, based on physicians' clinical experience. The initial dose of midazolam in the SAS grou...

Midazolam and Dexmedetomidine Affect Neuroglioma and Lung Carcinoma Cell Biology In Vitro and In Vivo.

WHAT THIS ARTICLE TELLS US THAT IS NEW: BACKGROUND:: Several factors within the perioperative period may influence postoperative metastatic spread. Dexmedetomidine and midazolam are widely used general anesthetics during surgery. The authors assessed their effects on human lung carcinoma (A549) and neuroglioma (H4) cell lines in vitro and in vivo.

Sedation with dexmedetomidine prolongs the analgesic duration of brachial plexus block: a randomised controlled trial.

Dexmedetomidine, an alpha 2 receptor agonist, prolongs nerve block duration when administered in conjunction with peripheral nerve blocks. We hypothesised that sedation with dexmedetomidine could also significantly prolong the analgesic duration of brachial plexus block (BPB) during orthopaedic surgery on the upper extremities.

Dexmedetomidine Sedation in Magnetic Resonance-Guided Focused Ultrasound Thalamotomy: A Case Series of 3 Patients.

Magnetic resonance-guided focused ultrasound thalamotomy is an innovative minimally invasive treatment for medication-resistant tremor in patients with essential tremor and Parkinson disease. Sedation with common hypnotic agents is discouraged because the patient's cooperation is required during the procedure, and these drugs interact with the patient's tremor, interfering with the results of intraprocedural neurological evaluations. Dexmedetomidine may be the best choice for sedation during magnetic resona...

Safety and Efficacy of Remimazolam Compared to Placebo and Midazolam for Moderate Sedation during Bronchoscopy.

While the complexity of flexible bronchoscopy has increased, standard options for moderate sedation medications have not changed in three decades. There is need to improve moderate sedation while maintaining safety. Remimazolam was developed to address shortcomings of current sedation strategies.

Premedication With Midazolam or Haloperidol to Prevent Recovery Agitation in Adults Undergoing Procedural Sedation With Ketamine: A Randomized Double-Blind Clinical Trial.

We evaluate the effect of midazolam and haloperidol premedication for reducing ketamine-induced recovery agitation in adult patients undergoing procedural sedation. We also compare physician satisfaction and recovery time.

Low-Dose Fentanyl, Propofol, Midazolam, Ketamine and Lidocaine Combination vs. Regular Dose Propofol and Fentanyl Combination for Deep Sedation Induction; a Randomized Clinical Trial.

Need for procedural sedation and analgesia (PSA) is felt in emergency department (ED) more and more each day. This study aimed to compare the effectiveness of low-dose fentanyl, propofol, midazolam, ketamine and lidocaine combination with regular dose of propofol and fentanyl combination for induction of deep sedation.

Dexmedetomidine Pharmacokinetics and a New Dosing Paradigm in Infants Supported With Cardiopulmonary Bypass.

Dexmedetomidine is increasingly used off-label in infants and children with cardiac disease during cardiopulmonary bypass (CPB) and in the postoperative period. Despite its frequent use, optimal dosing of dexmedetomidine in the setting of CPB has not been identified but is expected to differ from dosing in those not supported with CPB. This study had the following aims: (1) characterize the effect of CPB on dexmedetomidine clearance (CL) and volume of distribution (V) in infants and young children; (2) char...

Effect of dexmedetomidine or propofol sedation on haemodynamic stability of patients after thoracic surgery.

Dexmedetomidine and propofol are commonly used sedative agents in non-invasive ventilation as they allow for easy arousal and are relatively well controllable. Moreover dexmedetomidine is associated with low risk of respiratory depression. However, both agents are associated with significant hemodynamic side effects. The primary objective of this study is to compare the influence of both drugs on hemodynamic effects in patients after thoracic surgical procedures receiving dexmedetomidine or propofol for non...

Subcutaneous dexmedetomidine for baclofen withdrawal during palliative sedation.

Sudden cessation of baclofen can produce a withdrawal syndrome even if it was previously orally administered. We present the case of a man who exhibited signs of baclofen withdrawal syndrome during palliative sedation. Attempts were made to induce muscle relaxation with ever-increasing doses of benzodiazepine. Ultimately, control over the withdrawal syndrome was regained by using a continuous subcutaneous infusion (CSCI) of dexmedetomidine, a highly selective α adrenergic agonist. Very limited published re...
