Hemodynamic impact of dexmedetomidine administration in 15,656 noncardiac surgical cases.

Journal Article (Journal Article)

STUDY OBJECTIVE: To assess the hemodynamic impact of dexmedetomidine administration in a large cohort of patients undergoing routine noncardiac surgery. DESIGN: Retrospective database analysis. SETTING: Major academic medical center. MEASUREMENTS: A valid electronic preoperative history and physical record and electronic perioperative anesthesia record of all adults undergoing noncardiothoracic procedures of > 60 minutes duration between January 2007 and September 2008 were reviewed. The primary composite endpoint was systolic blood pressure < 80 mmHg for > 5 minutes, heart rate < 40 bpm for > 5 minutes, or administration of vasoconstrictors (> 500 μg of phenylephrine by bolus or infusion or any epinephrine) or atropine intraoperatively. MAIN RESULTS: A total of 15,656 cases, of whom 2,688 (17%) received dexmedetomidine preoperatively or intraoperatively and 12,968 (83%) did not receive dexmedetomidine, was identified. A significantly higher percentage of patients in the dexmedetomidine group met the composite endpoint criteria (27% vs 19%, P < 0.0001). However, there was no significant difference in the overall incidence of intraoperative hypotension (5.3% dexmedetomidine, 6% no dexmedetomidine) or bradycardia (0.4% in both groups). Dexmedetomidine patients received more phenylephrine or atropine (23% vs 15%, P < 0.0001). CONCLUSIONS: In a large cohort of routine clinical practice cases, dexmedetomidine administration was not associated with more hypotension or bradycardia.
