The Effect of Dexmedetomidine on Oral Mucosal Blood Flow and the Absorption of Lidocaine

[Practical potentials of using dexmedetomidine in oral and maxillofacial surgery]

Dexmedetomidine is a selective α₂ adrenoreceptor agonist. The drug has a set of useful properties due to wide prevalence of the receptors in a body. The article presents review of the literature of using dexmedetomidine in anesthetic practice of various surgery fields which positive results may be extrapolated to dentistry and maxillofacial surgery to solve important anesthesiologic problems. Inclusion of the drug in routine oral and maxillofacial surgery anesthesia can bring a significant amount of benefits: safe sedation for dental interventions, sedation for compromised airways without respiratory depression, improvement of intraoperative and postoperative analgesia, reduction of postoperative nausea, vomiting and postoperative shivering incidence, nephroprotection and stability of hypotensive hemodynamics, decrease of intraoperative blood loss. Thus, the dexmedetomidine may be a useful agent for anesthesia in oral and maxillofacial surgery that increases anesthesia safety and quality of medical care.
