results seventy-five patients completed the study. compared to saline, patients who received 1 and 5 mg/kg of aminophylline demonstrated decreased extubation times (mean ± sd) (12.26 ± 7.33 vs. 11.15 ± 8.62 and 10.4 ± 4.78 min, respectively, p = 0.001) with higher bis values (p = 0.001). however, the recovery and discharge times from the pacu were no different between the aminophylline and sali...

BACKGROUND AND OBJECTIVE Both the bispectral and the patient state indices are derived from the electroencephalogram and have been proposed as a measure of the same clinical target, the hypnotic component of anaesthesia. The present study evaluated whether there is concordance between the bispectral and the patient state indices with regard to end-points measured simultaneously in patients unde...

BACKGROUND Pain assessment is an immense challenge for clinicians, especially in the context of the intensive care unit, where the patient is often unable to communicate verbally. Several methods of pain assessment have been proposed to assess pain in this environment. These include both behavioural observation scales and evaluation of physiological measurements such as heart rate and blood pre...

Introduction: Bispectral Index is an objective tool to assess electroencephalographic activity and measure the effect of certain sedatives and hypnotics on the brain. In addition, there are certain subjective tools such as the observer's assessment of alertness and sedation which are used. The correlation between BIS and the concentration of propofol in the brain, and the relationship between t...

BACKGROUND Aging is associated with a reduction in anesthetic requirements. The effects of age on the electroencephalographic response to inhalational anesthesia have not been well documented. The objective of the present study was to determine the influence of age on hypnotic requirement and electroencephalographic derivatives such as bispectral index and 95% spectral edge frequency associated...

BACKGROUND Neuropsychological dysfunction is a major cause of morbidity and mortality after cardiac surgery. AIM To evaluate if intraoperative cerebral desaturation and depth of anesthesia measured by bispectral index are related to postoperative cognitive dysfunction in cardiac surgery. MATERIAL AND METHODS Prospective study in patients undergoing elective cardiac surgery with cardiopulmon...
