[Clinical evaluation of the laryngeal mask airway using capnogram].

Abstract

The laryngeal mask airway (LMA) was clinically evaluated using capnogram in patients who breathed spontaneously under the combination of general and spinal anesthesia. Using the LMA, the airway was maintained without jaw lift and no remarkable hemodynamic change was observed during its insertion and removal. Capnogram was useful to confirm the intact airway and to monitor the respiration. Respiratory depression was observed after thiopental administration and enflurane inhalation. The respiration recovered promptly following the increase of respiratory rate (RR) and tidal volume at first, and it made a further recovery following increase in RR. The use of the LMA under light inhalation anesthesia is hence a useful combination with regional anesthesia.
