Active clinical trials for "Intraoperative Awareness"

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.

Isoproterenol is used as a cardiac stimulant in electrophysiology studies (EP). Preliminary data suggests that administration of isoproterenol increases the Bispectral index (BIS). BIS is used to monitor neuronal signals under anesthesia. The BIS level is suggested to correspond to the level of consciousness. We hypothesize that isoproterenol increases BIS values because it increases the patient's level of consciousness through its central nervous system (CNS) stimulatory effects. In this study, we will administer increasing doses of isoproterenol to EPS patients. We will measure the BIS levels continuously before and after isoproterenol administration. In addition, we will test the level of awareness of patients by their response to a modified isolated forearm technique.

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.

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.

A study to find agreement of the infraorbtal BIS placement as compared to standard frotal placement

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 was to evaluate the effect of the 15 weeks Chan-Chuang qigong program with breathing meditation on quality of life and interoceptive awareness in patients with breast cancer during chemotherapy.

The purpose of the study is to evaluate and compare the feasibility, efficacy and safety of IAADS (Improved Anaesthetic Agent Delivery System) for propofol anaesthesia against manual control using bispectral index in paediatric patients undergoing open heart surgery under cardio-pulmonary bypass.

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.
