Filter by:Aim: To compare the effect of procedural anesthesia management with ketofol and propofol on the sonographic optic nerve sheath diameter in the endoscopic retrograde cholangiopancreatography (ERCP) procedures.
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.
Drug-induced sleep endoscopy (DISE) is the most used technique for identifying the obstruction site associated with obstructive sleep apnea (OSA). This is due to the fact that it allows many patients to be examined in a daytime setting. This procedure uses sedative drugs to mimic natural sleep. However, associations with the site of upper airway (UA) collapse during natural sleep remain unclear. The aim of this explorative study is to identify UA collapse in patients with OSA using endoscopic techniques as well as flow shape characteristics and sound analyses during natural and drug-induced sleep. Furthermore, we want to optimize the measurement set-up of natural sleep endoscopy (NSE).
The investigators will record 120 patients who received general anesthesia, their EEG data recorded from Bispectral Index (BIS) machine for emperical mode decomposition (EMD) analysis, the investigators decomposed EEG signal to different oscillations and tried to observe the differences between hypnotic medications through EEG analysis.
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 investigates correlation between dreaming in propofol anesthesia and an Observer-rating-scale of facial expression after gastrointestinal endoscopy in adults. It also compares dreamers and non-dreamers in age, BMI, propofol dose, duration of procedure, mean arterial pressure, pulse values and Bispectral index values.
Adequate sleep is necessary for physical and mental health of human being. Although surgery and anesthesia techniques have improved in resent years, postoperative sleep disturbance remains a challenging problem in surgical procedures1. Postoperative sleep fragmentation and poor sleep quality can not only result in hyperalgesia and a delay in postoperative recovery2, lack of sleep after surgery can also bring many potential adverse effects such as cognitive disorders (such as delusions, delirium), chronic pain, mood disorders, metabolic disorders, and pro-inflammatory changes3-5. Previous studies have reported that age, preoperative comorbidity and severity of surgical trauma were independent factors that associated with postoperative sleep disturbance6,7. Our prior studies have also found that patients are more likely to experience decreased sleep quality after receiving general anesthesia, which was characterized by a decrease in each sleep stage8. Propofol and sevoflurane are commonly used general anesthetics in clinical practice. The choice of anesthetic may also affect the cognitive outcome after surgery, but the results of clinical studies have always been contradictory. Some studies report that the cognitive results after inhalation are worse than those after intravenous anesthesia. And the incidence of dreaming was significantly higher in the sevoflurane anesthesia group compared to the propofol group9-11. Another study conduct among infants proved that compared with propofol-remifentanil, sevoflurane appears to be associated with less sleep disturbances in the first weeks after surgery12. Based on these conflicts, the aim of the current study was to compare the effect of propofol vs sevoflurane on early postoperative sleep quality and complications of patients receiving laparoscopic surgery after general anesthesia.
Catheter ablation (CA) is an established therapeutic option for patients with symptomatic atrial fibrillation (AF). During the procedure, patients are usually sedated and analgesized, most commonly by administration of Propofol combined with opioids under the supervision of the electrophysiologist. However, due to the depressive effect of Propofol on the respiratory system, this regimen is not without risk. Dexmedetomidine is a highly selective alpha 2 agonist that demonstrates both analgesic and hypnotic properties with only weak effect on the respiratory system. The pharmacological profile of Dexmedetomidine may be advantageous for sedation during CA of AF. The aim of this randomized trial is to test this hypothesis and explore the safety and efficacy of Dexmedetomidine during CA of AF.
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.
