Perioperative Sedation in Mechanically Ventilated Cardiac Surgery Patients With Dexmedetomidine-Based Versus Propofol-Based Regimens

Sedative agents used during cardiac surgery can influence the patient's time to extubation, intensive care unit (ICU) and hospital length of stay, and incidence of delirium. This study evaluates the effects of the intraoperative and postoperative use of dexmedetomidine versus propofol infusions...

Shrnutí:Sedative agents used during cardiac surgery can influence the patient's time to extubation, intensive care unit (ICU) and hospital length of stay, and incidence of delirium. This study evaluates the effects of the intraoperative and postoperative use of dexmedetomidine versus propofol infusions. This 19-month retrospective observational study at an academic medical center included 278 patients 18 years of age or older who underwent coronary artery bypass grafting (CABG), valve replacement surgery, or combined CABG plus valve surgery, who received either a dexmedetomidine or propofol infusion in addition to general anesthesia intraoperatively. The primary outcome was time to extubation. The secondary outcomes were ICU and hospital length of stay and incidence of delirium. Use of dexmedetomidine (n = 69) as an intraoperative and postoperative sedative as opposed to propofol (n = 209) was significantly associated with increased likelihood of extubation (ie, shorter time to extubation; hazard ratio = 1.63, 95% CI = 1.21-2.19, P = 0.001). There was no significant association between use of dexmedetomidine and ICU discharge ( P = 0.99), hospital discharge ( P = 0.52), and incidence of delirium ( P = 0.27) after adjusting for other covariates. Conclusion and Relevance: Dexmedetomidine increased the likelihood of extubation when compared with propofol, with no increase in ICU or hospital length of stay or incidence of delirium. Our study is unique in that there was no crossover between patients who received dexmedetomidine and propofol infusions intraoperatively and postoperatively Dexmedetomidine-based regimens could serve as a suitable alternative to propofol-based regimens for fast-track extubation.
