Filter by:The investigators compared the effects of remifentanil and dexmedetomidine administered under general anesthesia on hemodynamics, postoperative pain, recovery, postoperative nausea, vomiting, shivering, patient's and surgeon's satisfaction in patients undergoing elective rhinoplasty. A single-center, prospective, blinded, randomized controlled trial. After the approval of the hospital ethics committee (KA22/12), fifty volunteers aged 18-65 years who underwent rhinoplasty under elective conditions accepted the study in the American Society of Anesthesiologists (ASA) I-III class. The patients were randomly divided into the remifentanil group (group R) and the dexmedetomidine group (group D). Group R (n=25) was initially to receive remifentanil 0.01-0.2 g/kg/min without intraoperative loading. Group D (n=25) dexmedetomidine, was initiated with a bolus of 1 mg/kg and received 0.2-0.7 g/kg per hour as an infusion during surgery.
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.
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.
Our aim was to investigate whether remifentanil use in both infusion and bolus techniques could provide sufficient sedation and analgesia without serious adverse effects for central venous access device procedures under monitored anesthesia care.
Background: Application of total intravenous anesthesia (TIVA) may be considered as unpractical when compared with inhalational anesthesia. Although it is mostly not recommended, mixing intravenous agents seems to be popular in clinical practice. The aim of the study was to investigate the possible clinical drawbacks of using remifentanil-propofol admixture (MIXTIVA) for TIVA.
This study will investigate the potential of guiding remifentanil analgesia during cardiac and vascular surgery in moderate to high risk patients requiring general anesthesia.
The best opioid for bronchoscopy is still unclear.This randomized double-blind prospective study was conducted on a total of 60 patients who were randomly allocated into 3 groups: Group S received sufentanil 0.1 mcg/kg, Group F received fentanyl 1 mcg/kg and Group R received remifentanil target-controlled infusion with effect-site target concentration of 1ng/ml. Patients in all groups received midazolam to achieve moderate levels of sedation as assessed by the Narcotrend (NT; between B1 and C2). Adverse events, patient tolerance and physician satisfaction were analized.
Co-administration of propofol and remifentanil is considered to be an ideal total intravenous anesthesia technique, which is widely used in induction and maintenance of general anesthesia. Remifentanil and propofol can be mixed in polypropylene syringes for one hour with a remaining concentration of 91% in small concentrations of remifentanil. However, delivery of remifentanil-propofol mixture by target-controlled infusion(TCI) for general anesthesia in surgical procedure has not been described. Breast cancer surgery ( including modified radical mastectomy and breast-conserving surgery) is a less time-consuming procedure for patients with breast cancer with one-hour duration in our hospital. This pilot study was to examine the merit of remifentanil-propofol mixture as a GA regimen for breast cancer surgery.
The relationship between the target effect site concentration of remifentanil and the pupil diameter and reactivity in response to a standard noxious stimulus in cardiac surgery during extra corporeal circulation will be evaluated.
Postoperative hyperalgesia has been reported after intraoperative administration of small or high-dose remifentanil. Cyclooxygenase inhibitor exhibit preventive effects on the development of opioid-induced hyperalgesia. The aim of this study is to evaluate the preventive effect of intravenous ibuprofen (Caldolor®) on remifentanil-induced hyperalgesia
