[General anaesthesia with sevoflurane in dental surgery with use of LMA-Flexible and LMA-ProSeal].

To compare the laryngeal mask airways (LMA), LMA - Flexible (LMA-F) and LMA-ProSeal (PLMA) with respect to airway management in dental surgery. 35 patients, with the pathology of stomatological area (cysts of the lower jaw; diseases maxillary sinus) were investigated during the operation. Anesthesia was induced with propofol, fentanyl and atracurium besylate. Anesthesia was maintained with sevoflurane and neuromuscular blockade with mechanical ventilation. The operation lasted 30-40 min. For airway management was used LMA-F in 20 patients, in 15 patients was made PLMA. There were no statistically significant differences between LMA-F/PLMA groups for SpO(2), ET CO(2) or airway pressure during anesthesia. As for the gas exchange no difference was noticed in both groups (p<0.05). Undesirable laryngo-phryngeal reflexes were not noticed in total myoplegia. The reaction of cardiovascular system while installating LMA-F and PLMA was absent. As for the gas exchange no difference was noticed in both groups (p<0.05). A correctly placed LMA-F or PLMA during general anaesthesia with sevoflurane is effective for airway management in surgery.
