Filter by:ConsCIOUS-2 is a multi-site study exploring the cognitive state of the Isolated Forearm Test (IFT) responder while under anesthetic.
The primary aim of this study is to determine whether spatiotemporal characteristics of multisensory evoked potentials can be used as a marker of consciousness (awareness) under anesthesia. The secondary aim is to characterize changes in the characteristics of evoked potentials under anesthesia in both single sensory modality (visual, auditory) and across sensory modalities.
This study compares manual total intravenous anesthesia (TIVA) and target-controll infusion (TCI) in reduction of awareness and dreaming, and the haemodynamical stability during operation. Half of patients will be anesthetized using manual TIVA and other half using TCI.
Obesity is a chronic disease that affects quality and duration of life negatively. It's not clearly known the effects of low flow anesthesia on cerebral oxygenation with high-risk morbidly obese patients. In this study, it was aimed to compare the effects of general anesthesia with low flow (0,75 L/min) and normal flow (1,5 L/min) on cerebral oxygenation and depth of anesthesia in morbidly obese patients in bariatric surgery.
The aim of this study is to evaluate the validity of perfusion index to determine the level of anesthesia in comparison with auditory evoked potential in children undergoing tonsillectomy.
The aim of the study was to assess the influence of volatile induction of general anaesthesia with sevoflurane using two different techniques and intravenous anaesthesia with propofol on the possible presence of epileptiform electroencephalograph patterns during the induction of general anaesthesia. We aimed to verify whether presence of epileptiform patterns (EPs) defined as polispikes (PS), rhytmic polispikes (RPS), periodic epileptiform discharges (PED) on Electroencephalographs (EEGs) influence the behaviour of values of the Bispectral Index (BIS), State (SE) and Response (RE), A-line Auto Regressive Index (AAI) derived from middle latency auditory evoked potentials (MLAEP) during the induction of general anaesthesia using abovementioned techniques and such variations may be useful in detection of presence of EPs.
This study evaluated the effects of preoperative anxiety and dosage of anesthesia on IVF success. Half of participants according to the recorded Beck's Anxiety Inventory (BAI) score: a low-anxiety group, while the other half high-anxiety group.
DREAMY is a prospective, multi-centre observational cohort study using a mixed methods approach to provide quantitative and qualitative data on accidental awareness under general anaesthesia (AAGA) in obstetric surgery patients. Obstetric patients undergoing surgery, such as emergency caesarian section under general anaesthesia, are thought to be at higher risk than any other surgical cohorts for AAGA. Patients recruited to the study will be screened for AAGA using a standardised questionnaire on three occasions over 30 days. Follow up with structured interviews for all AAGA patients will occur over 12 months.
Awareness during anesthesia with intraoperative memory occurs when the patient is able to process information and produce specific responses to several stimuli. Anecdotal evidence suggests that children exposed to therapeutic suggestion consisting of gently encouraging, positive words spoken to them during emergence from anesthesia seem to arouse after surgery with less agitation, less pain and lower requirements for pain medications. Therapeutic suggestion has been associated with positive results in some adults during surgery, but it is unknown how therapeutic suggestion affects children. A newborn's recognition and preference for their mother's voice occurs early in life, very likely during fetal development. Additional evidence, revealed that at least as early as 4 months of age, infants process auditory stimuli from their mother's voice at a higher amplitude than they process auditory input from female strangers, suggesting that maternal voice stimuli undergo a unique form of cerebral processing that lends support for the existence of neurophysiologic mechanisms that reflect a child's preference for his/her mother's voice. This study aims to evaluate and compare the possibility of intra-operative awareness prevention by using either music listening or maternal sound listening in children undergoing cardiac surgery.
A primary aim of anaesthesia is to prevent awareness of surgery; ablation of the experience of surgery is the most secure way to prevent awareness with recall. Fortunately the incidence of awareness with recall (the patient can spontaneously remember the intraoperative event) is very rare (0.1-0.2%). However the investigators systematic review suggests that consciousness of intraoperative events may occur in approximately 37% of patients in experimental studies (as identified by the validated clinical procedure the isolated forearm test that does not require postoperative recall of the event). In this international cohort study, recruiting a minimum sample of 200 patients, the investigators will investigate the incidence of anaesthesia awareness (as identified by the isolated forearm test) following the induction of anaesthesia and before surgery.
