a b s t r a c t a 36-year-old male patient with posttraumatic cervical cord damage and resultant quadriparesis, demonstrated hypotension and periods of bradycardia. for most of his two-month stay in the intensive care unit (icu), he was dependent on dopamine support to maintain hemodynamic stability. keeping in mind evidence from the literature, that electrostimulation of acupoints neiguan (pc ...

Biomedical Engineering) Assessment of Mechanical and Hemodynamic Vascular Properties using Radiation-Force Driven Methods

Highlights • Spontaneous hemodynamic fluctuations display spatio-temporal organization. • Task-free fMRI has become a powerful approach for studying properties of large-scale brain networks and their clinical implications. • There remain challenges in interpreting results of task-free fMRI studies, as the neural origins of spontaneous hemodynamic signals are not well understood and fMRI data al...

background: cardiopulmonary bypass is associated with increased fluid accumulation around the heart which influences pulmonary and cardiac diastolic function. the aim of this study was to compare the effects of modified ultrafiltration (muf) versus conventional ultrafiltration (cuf) on duration of mechanical ventilation and hemodynamic status in children undergoing congenital heart surgery.mate...

Brain imaging based on functional MRI (fMRI) provides a powerful tool for characterizing age-related changes in functional anatomy. However, between-population comparisons confront potential differences in measurement properties. The present experiment explores the feasibility of conducting fMRI studies in nondemented and demented older adults by measuring hemodynamic response properties in an ...

background: keeping the patient in a sitting or semi-sitting position for time-consuming oncoplastic breast surgery is a major challenge for anesthesiologists due to several considerations. this cohort study was conducted on two groups of patients undergoing breast surgery. methods: study participants were categorized into two groups: one group was composed of normotensive women (group a) and t...

Hemodynamic instability frequently occurs in critically ill patients. Pathophysiological rationale suggests that hemodynamic monitoring (HM) may identify the presence and causes of hemodynamic instability and therefore may allow targeting therapeutic approaches. However, there is a discrepancy between this pathophysiological rationale to use HM and a paucity of formal evidence (as defined by th...

conclusions we found that 0.3 mcg/kg of sufentanil attenuates cardiovascular responses to double-lumen endobronchial intubation without adverse effects. background sufentanil is a potent opioid analgesic frequently used in clinical anesthesia. double-lumen endobronchial intubation induces profound cardiovascular responses in comparison with ordinary endotracheal intubation because of the larger...
