View clinical trials related to Unconsciousness.
Filter by:Most patients with minimal consciousness status in Critical Care Units (CCU) are considered as an 'unconscious patient' with a neurological examination. Evaluating these patients as unconscious patients may lead to neglect of psychosocial needs in patient-care, a continuation of unchanged treatment protocols for a long time and desperate evaluation of prognosis. In this study, the investigators aimed to evaluate the emotional responses of patients who were considered by the healthcare providers and relatives of patients as an 'unconscious patient' by using electrophysiological tests.
The aim of this study is to determine whether ALDH2 gene polymorphisms (G/G, G/A A/A) have effect on the potency of propofol.
It is thought that altered brain lactate handling is involved in the development of impaired awareness of hypoglycemia (IAH), i.e. the inability to timely detect hypoglycemia in people with type 1 diabetes (T1DM). Infusion of lactate diminishes symptomatic and hormonal responses to hypoglycemia in patients with normal awareness of hypoglycemia (NAH), resembling the situation of patients with IAH. It is unknown whether this attenuating effect is due to brain lactate oxidation or the result of lactate-induced alterations of global and regional cerebral blood flow (CBF). Normally, hypoglycemia causes a redistribution of CBF towards the thalamus, from where the sympathetic response to hypoglycemia is coordinated, but in IAH this effect is absent and global CBF is increased. We hypothesize that lactate infusion in patients with NAH will result in blunting of thalamic activation and/or enhanced global CBF. If so, these results may help delineating the pathogenesis of IAH which eventually creates new avenues to protect against the morbidity associated with hypoglycemia and IAH. Study design: Single-blind placebo controlled, randomized cross-over intervention study Study population: T1DM patients with NAH (n=10) Intervention: On two separate occasions, patients with T1DM and NAH will undergo a hyperinsulinemic euglycemic-hypoglycemic glucose clamp with or without the infusion of exogenous lactate. ASL-MRI will be applied to measure global and regional changes in CBF. Main study parameters/endpoints: The change in regional thalamic CBF in response to intravenous lactate infusion compared to placebo, during hypoglycemia
Memory priming under general anesthesia is a phenomenon of incredible interest in the study of consciousness and unconscious cognitive processing, and for clinical practice. However results from anesthesiological literature are divergent and methodologies vary. To overcome these limits, the present study aims at better defining the phenomenon of memory priming under general anesthesia, manipulating as experimental variables both the anesthetic drug used and the stimuli primed.
Background and Aim: Tubular feeding is used, in patients who cannot take food through their mouths, but the digestive system has the ability to digest food. This method is safe and affordable for the patient and results in maintaining the function of the digestive system and reducing the risk of infection and sepsis. The purpose of this study was to compare the three methods of the NG tube placement in intubated patients in the emergency department of university-affiliated hospitals of Isfahan from2016 to 2018. Materials and Methods: This study was a randomized and prospective clinical trial. The statistical population of this study was all patients who had been referred to the emergency department of Al-Zahra and Ayatollah Kashani hospitals in Isfahan between2016and2018. The sample size was 25 in each group, and in total 75 subjects. The first group was NG tube insertion by the conventional method, the second group was using brake cable and the third group was embeddedby highwayman's hitch or draw hitch, using a silk thread. For all patients, demographic characteristics and possible complications were recorded. Finally, the data were analyzed using SPSS20 software at two statistical levels of descriptive and inferential.
The electroencephalography (EEG) is a noninvasive medical technique for monitoring and recording the electrical activity of brain. The Hilbert-Huang Transformation (HHT) was proposed to decompose EEG signal into intrinsic mode functions (IMF). HHT can obtain instantaneous frequency data and work well for nonstationary and nonlinear data. We applied this method in perioperative EEG signal analysis in order to find the energy shift and quantify the energy change during general anesthesia. Ketamine was a depolarized sedative which was wildly used in anesthesia. We are trying to find the energy change after ketamine injection, and the interaction between different oscillations in EEG. The whole brain mapping for ketamine and other sedatives interaction is the next step.
Looking for strict normoglycemia in type 1 diabetes increases the risk of hypoglycemia, exposing to hypoglycemia unawareness. It has been shown that the early correction of hypoglycemia can help recovering the perception of hypoglycemia. The purpose of this prospective study was to assess the value of sensor-augmented insulin-pump therapy to treat hypoglycemia unawareness.
Patients with type 1 diabetes mellitus (T1DM) commonly experience hypoglycemia and develop impaired awareness of hypoglycemia. Many patients using continuous glucose monitoring (CGM) system to mitigate these complications, but continue to spend a significant amount of time in hypoglycemia. The long-term goal is to develop novel and readily available therapeutic approaches to improve hypoglycemia course and awareness in T1DM patients. The objective of this study is to determine whether amitriptyline will improve hypoglycemia course and the ability to recognize hypoglycemic events in T1DM patients who are using CGM.
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.
Type 1 diabetes mellitus (T1DM) can lead to cardiovascular, renal and neurological complications if left poorly-controlled over prolonged periods of time. However, lowering glycemic goals for diabetic patients increases their risk for hypoglycemia exposure. Hypoglycemia is associated with symptoms such as heart palpitations, fatigue, shakiness, anxiety, confusion, and blurred vision. Recurrent hypoglycemia leads to impairment of the body's autonomic and symptomatic responses to this condition, and can result in loss of awareness in the patient of the hypoglycemic state. Repeated incidences of hypoglycemia from loss of this awareness can result in even more hypoglycemic episodes and more severe outcomes, such as loss of consciousness, accidents, hospitalization and even death if left untreated. The aim of this study is to investigate whether adrenergic blockade through the use of low-dose carvedilol treatment can improve hypoglycemia awareness and the counterregulatory hormone responses to hypoglycemia in T1DM patients with impaired awareness of hypoglycemia.
