Active clinical trials for "Unconsciousness"

The aim of this study was to translate the SECONDs from French into Chinese and assess the validity and reliability of the Chinese version of the SECONDs .

This is a pilot randomised controlled trial investigating whether using modification of saccadic eye movements can control lateral unconscious tongue positioning and enhance fluency in adults with a confirmed developmental stammer. This study is being conducted as part of an MSc by research qualification at the Institute of Technology Sligo in Ireland with a view to extending to PhD. The setting is home setting with all assessments either taking place at home via video link or in the institute. The study is being conducted in conjunction with the Community Speech and Language Therapist and has attained ethical approval through Sligo University Hospital (SUH) Ethics Committee.

This study aims to assess the usefulness of pupillometry as a nociceptive indicator during elective orotracheal intubation in patients given intravenous lignocaine pre-intubation as compared to a placebo pre-intubation.

Hypoglycaemia unawareness is a common complication in patients with type 1 diabetes and with insulin-treated type 2 diabetes of long duration. The loss of autonomic symptoms to hypoglycemia does not solely depend on loss of adrenaline responses.Differences in sensitivity to catecholamines may also be involved. Reconciling the data on β2-adrenergic receptor polymorphism to those on loss of β-adrenergic sensitivity in diabetic patients with hypoglycemia unawareness, we hypothesize that hypoglycemia unawareness is at least partly the result of desensitization of the β2-adrenergic receptor and that patients who are homozygous for arginine at codon 16 are particularly susceptible for this desensitization process, whereas patients who are homozygous for glycine at codon 16 are resistant for desensitization. Objectives To determine whether, and if so to what extent, antecedent hypoglycemia reduces β2-adrenergic sensitivity in healthy subjects with Arg16 homozygosity. To investigate whether or not healthy subjects with Gly16 homozygosity are resistant to desensitization To confirm that antecedent hypoglycemia reduces the heart rate response to isoproterenol and to assess to what extent this reduced response is mediated by impairments in baroreflex sensitivity.

Novel technology enables it to monitor noninvasively the vital signs of a patient. Such a monitoring is immediately required to improve patient safety and to reduce hospital readmissions. In this study, novel bed- and wearable sensors are studied for this purpose.

Temporal dynamics of the EEG microstates show scale-free monofractal properties. This means that information is encoded in the same way at different scales. It may be postulated that these monofractal properties of the EEG microstate sequences constitute a necessary prerequisite of consciousness. We postulate that clinical variations of consciousness may also be linked to alterations of fractal properties of EEG microstates.

Sedation is often administered to relieve anxiety and discomfort during uncomfortable procedures in elderly patients. Patient control of sedation offers many potential benefits for patients and healthcare professionals, including improved safety and patient satisfaction. The investigators overall goal is to develop a patient controlled intravenous sedation system that is effective but very safe for the patient, and requires minimal supervision by a doctor or nurse. To fulfill these criteria, a sedation system should incorporate fail-safe safety mechanisms. A key safety-critical component is a method of objectively assessing the degree of sedation of the patient, and of preventing him from self-administering unsafe doses of the sedative drug. The investigators have designed a new sedation system that uses a measure of the speed of response of the patient to a defined non-noxious stimulus to determine whether or not it is safe to allow him to self-administer further levels of sedation. Before being able to execute a volunteer study in order to determine a rational selection of optimal threshold response time, a feasibility test on the handset device is required.

Prospectively evaluate newly established guidelines and make clinicians aware of inter-racial difference in propofol sensitivity.

In this study we aimed to investigate the performance and effectiveness of NOL and/or NOLedge as a tool for pain assessment in geriatric and critical ill non communicating patients. Our hypothesis was that NOL and the NOLedge may have good correlation with the health-care professional assessment PAINAD, BPS values, even with the use of the drugs affecting autonomic nervous system.

The aim of this study was to assess the clinical performance of two different ke0s (fast and slow) in terms of propofol effect-site concentration (Ce) during the loss and recovery of consciousness, using Marsh's pharmacokinetic model.The hypothesis to be tested was that the Ce of propofol predicted by the slow ke0 in the loss and recovery of consciousness is similar, differently from the fast ke0.
