Background And Objectives:
Bedside flexible fiberoptic bronchoscopy (FFB) with sedation has been recognized as a diagnostic modality in children. In certain circumstances, general anesthesia with endotracheal intubation is advocated. This study evaluates the usefulness of the laryngeal mask airway (LMA) as an alternative to endotracheal intubation during pediatric FFB.
Design, Setting, And Patients:
Between July 1995 and June 2000, we studied 92 children (51 girls; age range, 1 through 15 years) in the operating theater of a major tertiary children's hospital. The LMA was used in children with atelectasis, diffuse infiltrates, and those who required BAL under general anesthesia. The size of the LMA was chosen to accommodate a bronchoscope appropriate for the child's weight and age.
Results:
Procedures were well tolerated, no complications were observed, and oxygen saturation exceeded 95% in all patients. Major findings included mucoid impaction and purulent bronchial secretions, and BAL was successfully accomplished in all individuals.
Conclusions:
Diagnostic BAL or extraction of mucous plugs should be accomplished with optimal control of the airway under general anesthesia. The use of the LMA during FFB is safe, provides excellent patient comfort, and should be utilized as an alternative to endotracheal intubation.
