Filter by:this study is to assess the hemodynamic profile of ketamine compared with propofol in critically ill, mechanically ventilated adult Patients study will be carried out on 100 mechanically ventilated patients who received one sedative agent propofol or ketamine The patients will be randomized into two equal groups to receive either ketamine or propofol Group 1 (Ketamine group): ketamine is initiated at 0.5 mg/kg/h and titrated by 0.25 mg/kg/h every 15 minutes to a maximum dosage of 4 mg/kg/h to achieve appropriate sedation. Group 2 (Propofol group): Propofol is initiated at 0.3 to 0.6 mg /kg/hr. and titrated by 0.3 to 0.6 mg/kg/h every 5 to 10 minutes up to a maximum dosage of 4.5 to 4.8 mg/kg/hr. to achieve appropriate sedation.
Aminophylline is an intravenous drug commonly utilized for asthma. However, some preclinical studies and few case reports and case series have described its utility in decrease the timing of return of consciousness after Propofol anaesthesia with an intravenous bolus of 4 mg/kg. We aimed to compare its effect during a total Intravenous Anaesthesia with Target Controlled Infusion (TIVA-TCI) routinely utilized for general anaesthesia in our hospital.
No trials have evaluated the effect of a Midazolam bolus (routinely used for premedication before general anesthesia) on the Concnetration at the effector site of Propofol (CeP) of Eleveld and Schnider TCI models, routinely used for general anesthesia delivery.
The QT interval is a measure of the combination of cardiac depolarization and repolarization as it encompasses both the QRS complex and the J-T interval. QT, QTc, QTd prolongation or shortening has been associated with ventricular arrhythmias . In order to define non-torsogenic drug-induced arrhythmias, the index of cardio-electrophysiological balance (iCEB), which is a new marker calculated with the QT/QRS formula, has been defined. In our study, we planned to evaluate the effects of dexmedetomidine and propofol on cardiac electrophysiology with all these parameters, especially the newly defined iCEB.
A total of 120 patients (American Society of Anesthesiologist Physical Status 1-3) who signed a consent form among patients aged 19-80 years who are scheduled to undergo brachial plexus block and upper extremity surgery under monitored anesthetic care at our hospital were enrolled. Recruited patients are divided into three groups through computer-generated randomization by using the patient identification number assigned during patient recruitment. (40 people in each group) Standard monitoring is performed when the patient arrives at the operating room. Patients receive oxygen at 5-6 L/min using a simple facial mask, and receive a brachial plexus block under ultrasound guidance. After confirming the success of brachial plexus block, administration of propofol, remimazolam, or dexmedetomidine is started according to the assigned group. Assess the patient's level of consciousness through the MOAA/S (modified observer's assessment of alertness/sedation scale) scale. The drug injection ends when the skin suture is started after the main procedure. The time from the end of injection of each drug until MOAA/S becomes 5 points is measured. After the patient is transferred to the recovery room, the Aldrete score is assessed. The recovery profile, perioperative hemodynamic change, desaturation event, block duration, patient movement during surgery, patient satisfaction, and surgeon's satisfaction were investigated and analyzed for comparison.
This study compares hypnosis via virtual reality to sedation with commonly used intravenous anesthetic agents (propofol and remifentanil) during oocyte retrieval. The main objective of this prospective randomized controlled study will be a reduction of 50 percent of the doses of remifentanil and propofol administered during oocyte retrieval while maintaining satisfaction with the quality of care.
Background: Propofol based sedated anesthesia was widely used in percutaneous radiofrequency ablation and hypoxia/desaturation is one of the most frequent adverse events during this procedure. No effective methods have been found to prevent hypoxia/desaturation so far. The aim of this study was to evaluate whether the incidence of hypoxia/desaturation was different between the high-flow nasal cannula (HFNC) therapy group (which can provide heated and humidified oxygen up to 60L/minute.) and the nasal cannula group. Methods: In a randomized, prospective and double-blind study,100 patients undergo percutaneous radiofrequency ablation based on propofol sedation were assigned into two groups: the nasal cannula group (O2 [6 L/minute] was supplied via an HFNC) and the HFNC group (O2 [40 L/minute] was supplied via an HFNC). The primary outcome is the incidence of hypoxia/desaturation during surgery. Other adverse events were also recorded.
Awake craniotomy require a cooperative patient during resection neurosurgery phase. Anesthesiologist should guarantee analgesia, sedation, nausea and vomiting prevention, while maintaining normal vital parameters. Neurosurgeon could be help by Intraoperative electrocorticography to maximise lesion resection and avoiding neurologic sequelae. Propofol and remifentanyl have been largely used. Dexmedetomidine represents an alternative. However little is known about the role of dexmedetomidine on Intraoperative electrocorticography.
This study intends to investigate the effects of desflurane on postoperative sleep quality to guide perioperative patient management.
The aim of this study is to describe the BIS values and electroencephalographic patterns during total intravenous anesthesia with propofol-remifentanyl, in patients from 18 to 85 years.
