Randomized Controlled TrialHemodynamic and anesthetic advantages of dexmedetomidine, an alpha 2-agonist, for surgery in prone position.
The alpha2-agonist dexmedetomidine (Dex), a sedative and analgesic, reduces heart rate (HR) and blood pressure, and has been used in the practice of anesthesia. In this study, we aimed to evaluate the effects of Dex on hemodynamic variables, anesthetic sparing effects, and recovery profiles in patients who underwent surgery in prone position. The prone position itself can cause a decrease in the systemic blood pressure. ⋯ Thus, the use of Dex caused no detrimental effects on the hemodynamic variables in prone position. In addition, Dex decreased pressure response to intubation, and anesthetic and analgesic requirements, shortened recovery times, and decreased postoperative pain level. Dex may be an alternative to currently used adjunctive anesthetic agents in lumbar discectomy operations.
