Randomized Controlled Trial Multicenter Study Comparative Study Clinical Trial
Intramuscular dexmedetomidine as premedication for general anesthesia. A comparative multicenter study.
Dexmedetomidine is a new potent and selective alpha 2-agonist that might prove useful as a preanesthetic agent. ⋯ The results suggest that pretreatment with a single intramuscular injection of 2.5 micrograms/kg dexmedetomidine is efficacious, but significantly increases the incidence of intraoperative hypotension and bradycardia in ASA physical status 1 or 2 patients.
