Reducing anxiety and decreased neurological and metabolic response to surgical trauma become a requirement to be treated in the anesthetic plan, sedation there plays a key role in seeking to ensure an adequate hemodynamic stability during locoregional anesthetic techniques under conscious sedation, this being, sedation in which a patient responds normally to verbal stimuli, with preservation of cognitive function and coordination, without alteration of the ventilation or cardiovascular function. The ideal state of sedation depends on the type of patient, type of procedure and the medications used, however it is recommended to maintain a level of sedation between 2 and 3 or conscious sedation, according to Ramsay sedation scale to achieve greater wellness and collaboration, without requiring intervention to keep the airway, while maintaining adequate spontaneous ventilation and cardiovascular function normally held.
