ALMEIDA, Antonio Nogueira de et al. Dexmedetomidine for awake craniotomy without laryngeal mask. Arq. Neuro-Psiquiatr. [online]. 2005, vol.63, n.3b, pp.748-750. ISSN 0004-282X.

OBJETIVE: This paper reports the use of dexmedetomidine in three epileptic patients with cavernous angiomas that underwent awake surgery in order to map their speech areas. METHOD:Loading dose of dexmedetomidine varied from 1 mg/Kg/h to 3 mg/Kg/h over 20 minutes and maintenance dose from 0.4 mg/Kg/h to 0,8 mg/Kg/h. RESULTS: There was no occurrence of hemodynamic instability, convulsions or respiratory depression. Patients tolerated well the procedure. CONCLUSION: Dexmedetomidine was useful for awake craniotomy as it decreased patients’ level of consciousness but did not produce agitation. Laryngeal mask was not necessary to keep air ventilation.

Keywords : awake craniotomy; dexmedetomidine; epilepsy surgery; cortical mapping; neuroanesthesia.
