Abstract
To evaluate the usefulness of intravenous anesthesia with laryngeal mask airway(LM)for bronchoscopic procedures, 159 patients who had bronchoscopy in our hospital were examined retrospectively. Patients were divided into four groups according to the type of anesthesia. Group I; local anesthesia (58 cases), Group IIa; intravenous anesthesia with LMA(40 cases), Group IIb; inhalation anesthesia with LMA(36 cases), Group IIc; inhalation anesthesia with enhdotracheal intubation(25 cases). In each group, serial hemodynamic evaluation included(1)heart rate, (2)systolic blood pressure, (3)rate presssure product and (4)complications due to the procedures. In summary, patients in Group IIa showed minimum changes of heart rate, systolic pressure, and rate pressure product. Thus, intravenous anesthesia with LMA can reduce the load on patients and we conclude that this is the most useful type of anesthesia for bronchoscopy.
