Phase synchronization between cardiac and respiratory oscillations is investigated during anesthesia in rats. Synchrograms and time evolution of synchronization indices are used to show that the system passes reversibly through a sequence of different phase-synchronized states as the anesthesia level changes, indicating that it can undergo phase transitionlike phenomena. It appears that the syn...
Delirium is a common postoperative complication in adolescence patients and is associated with increased costs, morbidity and mortality. Recently, an association between the occurrence of delirium and increased risk of dementia has been revealed.

background: inadequate depth of anesthesia leads to release of stress hormones. electroencephalographic monitoring by bispectral index is a guide to asses the depth of anesthesia. the aim of the present study was to measure the serum cortisol levels as an index of stress response in patients who are candidates for coronary artery bypass graft surgery in two groups of patients. methods: sevent...
BACKGROUND The upper airway tends to be obstructed during anesthesia in spontaneously breathing patients. The purpose of the current study was to determine the effect of increasing depth of propofol anesthesia on airway size and configuration in children. METHODS Magnetic resonance images of the upper airway were obtained in 15 children, aged 2-6 yr. Cross-sectional area, anteroposterior dime...
