Filter by:Stress is defined as hormonal and metabolic changes in the biological system that follow any injury. The stress response occurs as a general systemic response to injury and includes a wide range of endocrinological, immunological and hematological effects. The level of stress in the surgical process can affect not only the patients outcome but also the overall health system. The two main agents used in maintenance for general anesthesia are inhalation and intravenous anesthetics. Both inhalation anesthesia and TIVA (Total Intravenous Anesthesia) approaches provide general anesthesia suitable for surgical operations. However, the mechanisms of action of these two methods differ and are not fully understood. The aim of investigators' for this study was to investigate the effect of different anesthetic agents on stress inflammatory response in the preoperative, peroperative and postoperative periods.
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.
The objective of this study is to evaluate the effect of adding dexmedetomidine on evoked potentials in adult patients undergoing spinal surgery under intravenous anesthesia
Perioperative anesthesia can affect postoperative cognitive function. In our previous study, intraoperative dexmedetomidine (Dex) infusion reduced the incidence of delirium within the first 5 days after brain tumor. However, the mechanism is still unclear. With the development of neuroimaging, multimodal neuroimaging technology provide a new method to explore the underlying mechanism. Therefore, the purpose of this study is to analyze the alterations of brain network under sedation and anesthesia by different anesthetics in patients with supratentorial glioma and their association with cognition.
The aim of this study is to compare the efficacy of dexmedetomidine and propofol on decreasing stress in mechanically ventilated patients by using salivary alpha-amylase as a stress marker.
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.
This study was a single-center, prospective, 2-year observational cohort study. The study subjects were ICU patients requiring vasopressor drugs and requiring sedation. According to the use of ciprofol or propofol in the treatment plan (determined by the doctor in charge according to the condition of the subjects), they were divided into groups: ciprofol group and propofol group. A total of 456 subjects were planned to be enrolled, including 304 subjects in the cyclopofol group and 152 subjects in the propofol group. The data of this study were obtained by extracting the routine clinical diagnosis and treatment records of the enrolled subjects.
This study will be carried out to compare the efficacy of dexmedetomidine, propofol or lidocaine infusions in attenuation of hemodynamic responses to pneumoperitoneum during adult laparoscopic cholecystectomy using electrical cardiometry.
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.
