Dexmedetomidine Is a Factor that Improves the Quality of Otolaryngological Surgery

Microsurgical operations such as middle ear surgery rely heavily on visibility of the
surgical field. Anesthetic techniques such as controlled hypotension have been developed to improve
surgical field visibility by attempting to decrease bleeding. Many agents have been utilized to achieve
controlled hypotension intraoperatively. Dexmedetomidine is a relatively newer agent which works on
alpha-2 receptors to decrease sympathetic tone.
