Active clinical trials for "Unconsciousness"

This research study is designed to investigate the effect of hypoglycemia (low blood sugar) on blood flow to and biochemistry in the brain.

This study looks at advanced airway management in critically ill or injured patients treated by physician manned emergency medical services, comparing early (on-scene) intubation to late (emergency department) intubation.

The purpose of this study is to evaluate the effects of different dexmedetomidine on the propofol requirement for loss of consciousness undergoing bispectral index.

Until today there is no standard-monitoring to specifically reflect the analgesic component of general anesthesia. Quality and safety of general anesthesia are of major clinical importance and can be improved by limiting the administration of opioid analgesics to the minimum dose needed. This study therefore examines the quality of three different monitoring techniques (PhysioDoloris, MetroDoloris, Lille, France, SPI (Surgical Plethysmographic Index), GE Healthcare, Helsinki, Finland and AlgiScan, IDMed, Marseille, France) in assessing the level of analgesia during general anesthesia. Therefore a standardized painful stimulus is applied under different levels of analgesic drugs. The monitor's indices are compared to clinical signs such as an increase in heart rate and blood pressure.

Using very slow or fast propofol intravenous injection, monitored using standard American Society of Anesthesiology (ASA) standard and SEDLine EEG (Med Tech), the patient was evaluate by a neurologist every 30 sec using the FOUR coma scale.

This is a single center, double blind randomized cross over design trial that will compare the impact of N-acetyl cysteine (200 mg) vs. saline infusion during experimental hypoglycemia on day one on the responses to experimental hypoglycemia on day two. 18 participants will be studied twice, 8 weeks apart. On each occasion they will undergo a 2 hour hypoglycemic clamp (target 50 mg/dl) in the morning and in the afternoon on day one and then again on the morning of day 2 and day 3. During the morning clamps, samples will be collected for later measurement of serum epinephrine levels, plasma and red blood cell NAC, cysteine, and glutathione concentrations and GSH/GSSG ratios (redox status), and participants will be asked to complete a hypoglycemia symptom questionnaire

The primary aim of this study is to investigate the correlation between the length of ICU stay and a newly developed FIVE score in neuro-intensive care patients. The secondary objectives are to evaluate the impact of the FIVE score on hospital length of stay, Modified Rankin Scale, and mortality, as well as to determine the correlation between the GCS, FOUR, and FIVE scores

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 purpose of this study is to investigate the effect of spinal anesthesia on ED50 and BIS50 of etomidate for the loss of consciousness (LOC) by using up-and-down method.The hypothesis was that spinal anesthesia could significantly reduce the etomidate bolus dose for the LOC and could also achieve hemodynamic stability during anesthesia induction.

Propofol in combination with remifentanil or midazolam can result in synergistic or additive effect. The patients who are scheduled to undergo general anesthesia are enrolled in this study. 120 patients will be randomly allocated to 3 groups(P, PR, PMR). The patients in group P will receive general anesthesia only with propofol and group PR and PMR will receive 0.25 mcg/kg/min remifentanil infusion prior to propofol. The patients in group PMR will receive 0.03 mg/kg bolus dose of midazolam 1 min after start of the remifentanil infusion. 'Success' is defined as loss of both verbal response and eyelash reflex in 2 min after propofol administration. When 'success', the next patient will receive the same dose(in 18/19 probability) or 0.25 mg/kg lower dose(in 1/19 probability) of propofol. When 'failure', the next patient will receive 0.25 mg/kg higher dose of propofol at induction period.
