View clinical trials related to Intraoperative Awareness.
Filter by:Intraoperative awareness which means the recall of experiences recorded in patients' memories during general anesthesia in the postoperative period is an important issue in anesthesia practice. The aims of this study are to investigate the incidence and causes of awareness during general anesthesia, incidence of dreaming during anesthesia, intra-operative experiences of patients who report awareness, the risk factors that may be associated with awareness, to analyze the frequency of posttraumatic stress disorder in cases with awareness and possible awareness, the risk factors that may be associated with PTSD in Turkish adults. Adult patients will be evaluated 4 time following emergence (a) One hour after emergence, (b) Twenty four hour after emergence (c) One week after emergence (d) One month after emergence. The first interview will be made face-to-face in the recovery unit, and other interviews will be made by phone. Each interview will be conducted using the same structured interview (Brice Interview). Descriptive statistics will be used to determine the incidence of awareness. χ2 test will be used for comparison between groups. Logistic regression will be used to determine the risk factors associated with awareness and PTSD. We believe that this study will contribute to the prevention of the problem by determining the real frequency and causes of intraoperative awareness under general anesthesia, determining the experiences and results of patients, and analyzing the associated risk factors.
With the rise in number of surgeries, the medicolegal issues are on rise especially if patient had intraoperative awareness, which can also be detrimental to psychosocial behaviour of patient. Investigators plan to compare the BIS values, 'which is an indicator of awareness', from supralabial to standard forehead placement sites. If the results are corroborative then the supralabial site can be used for BIS monitoring in neurosurgical cases where it is not possible to to apply the forehead BIS strips.
Age has been related to awakening propofol concentration at effector site of TCI, but not to the loss of consciousness concentration, neither to the concentration of body movements during surgery, that can be interpreted as a sign of light anesthesia and lead to awareness. This study aims to determinate the incidence and the propofol TCI concentration at the effector site, in patients undergoing general anaesthesia without NBDs, of any patients body movements, defined as any spontaneous movements (but no reflex movements) during surgery.
Using esmolol during anesthetic maintenance of laparoscopic bariatric surgery significantly decreases anesthetic, analgesic requirements, postoperative pain, PNV and postoperative hypoxia.
The aim of the study is to determine the psychometric properties of Perioperative Satisfaction Scale in Regional Anesthesia. In the Turkish version of the scale, a blind reverse translation method will use. And validity and reliability analyses will conduct.
Sevoflurane based inhalational anaesthesia is the preferred mode of anesthesia for small duration cases. But in recent times, concept of rapid discharge, day care procedures, and green environment has created the need of new modalities of anaesthesia for such cases. Considering such factor, investigators have planned using TIVA i.e. total intravenous anaesthesia with Inj. Propofol and Inj. Dexmedetomidine infusions for maintenance of anesthesia in Modified Radical Mastectomy (MRM). By comparing the two modalities of anaesthesia i.e. TIVA vs Inhalational investigators are trying to find out whether TIVA is feasible, cost effective and comparable to inhalational anaesthesia in terms of intraoperative hemodynamic stability, pain, intraoperative awareness and recovery profile. This comparison and analysis will help to determine if TIVA can be used as the sole mode of anaesthesia during MRM as it will initiate early discharge of patient and will contribute to the Green OT concept.
Closed-loop infusion system for target controlled infusion of propofol by using TCI pump designed by BD Technology. (Germany) guided with entropy and surgical pleth index (GE) will not only prevent awareness from Anesthesia but also optimise the dose anesthetic agents based on feedback from adequacy of Anesthesia monitoring. Which not only reduces Anesthesia agents but also enhances recovery from Anesthesia. Innovation using TCI combined with closed-loop controlled intravenous anesthesia under the guide of Entropy.In this study we performed a randomized, controlled, study to compare closed-loop control and open-loop control of propofol by using the Entropy and SPI guided closed-loop infusion system.
The profiling of bi-spectral index (BIS) monitored facilitation of general anesthesia (GA), including, anesthesia induction and maintenance of GA depth state, emergence characteristics, and postoperative recovery parameters, is now extensively available. However, majority of the data supporting the use of BIS have emanated from western Caucasian patient population. Though research on BIS monitoring have also emerged from Asian subcontinent, the data generated, at the best, is too scattered, random, and non-homogenous to reflect onto how BIS guidance fares in Asians on a population basis. We aim to undertake a multi-centric prospective cohort trial in Asian patient population to analyze as to whether BIS guidance toes the profiling and the evidence in Caucasians.
The study evaluates the general anesthesia management with BIS monitorization in terms of hemodynamic stability, drug concentrations and drug consumption in patients who underwent surgery due to intracranial pathology and who were divided in three different GCS groups.
Patients undergoing caesarean delivery under inhalation anaesthesia are at a high risk of awareness, especially in the period before delivery. The investgators assessed the effects of remifentanil on the bispectral index (BIS) in the interval before delivery.
