Transplanted-like Heart in Critical Ill Patients
In Brief
A clinical study evaluating Gravitational sympathetic stimulus for Autonomic Nervous System Dysfunction in Critically Ill. Completed, enrolled 150 participants across 2 sites.
Detailed Summary
The purpose of this study is to measure the dysfunction of the autonomic nervous system in modulating the heart rate variability and baroreflex control in critically ill.
Study Details
Timeline
Interventions
Autonomic nervous system (ANS) activity is assessed by means of HRV, SAP variability and baroreflex control analysis daily from day 1 to discharge from ICU or day 28. Analysis is performed (i)at rest in supine position with bed at zero degrees of inclination (ii) during modified tilt (MTILT) and (iii) recovery from MTILT in supine position at zero degrees. In a subgroup of patients motor sympathetic nervous activity (MSNA) is recorded at day 1,2 and 7. MTILT consists in elevating head and trunk of patients at 60 degrees and lowering legs at 15 degree with a standard critical care bed. MSNA is recorded from the external peroneal nerve with microneurographic technique.
