However, use of dexmedetomidine is limited by its heart rate (HR) and arterial blood pressure lowering effects. Moreover, CV19 is associated with cardiac manifestations including bradyarrythmias. The hemodynamic effects of dexmedetomidine have not been previously studied in CV19 patients. We evaluated the effects of dexmedetomidine on hemodynamic and respiratory parameters of CV19 patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>In this single center study, all CV19 patients receiving dexmedetomidine for sedation during a one year period were included. Our primary outcomes included changes in HR, mean arterial pressure (MAP), respiratory rate (RR), partial oxygen pressure of arterial blood\/fraction of inspired oxygen\u2010ratio (PF\u2010ratio), and Richmond Agitation and Sedation Score (RASS) during dexmedetomidine administration.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      We identified 39 patients with a mean (SD) age of 58.3 (12.7) years.

During the 12\u2010hour follow\u2010up period, HR decrease was significant at 2 to 12\u00a0h. Incident bradycardia (&lt;45\/min) was reported in 12 (30.8%) patients and it was associated with lower plasma C\u2010reactive protein, Pro\u2010calcitonin, and troponin T levels. There was no change in MAP compared to baseline.
