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.

Randomized Controlled Trial Comparative Study Clinical Trial
A prospective, comparative trial of three anesthetics for elective supratentorial craniotomy. Propofol/fentanyl, isoflurane/nitrous oxide, and fentanyl/nitrous oxide.
Different anesthetic agents have different effects on cerebrovascular physiology. However, the importance of these differences in neuroanesthetic practice are unclear. In an effort to determine whether important clinical differences are present, the authors compared three anesthetic techniques in 121 adults undergoing elective surgical removal of a supratentorial, intracranial mass lesion. ⋯ Although there are modest differences among the three tested anesthetics, short-term outcome was not affected. These results indicate that, despite their respective cerebrovascular effects, all of the anesthetic regimens used were acceptable in these patients undergoing elective surgery.
