Diagnostic indications for flexible bronchoscopy in the initial
investigation of children with suspected foreign-body (FB) aspiration have
not been evaluated prospectively. We prospectively collected history,
clinical, and radiologic findings at prebronchoscopic examination of all
children referred for suspected FB aspiration between February 1993 and
September 1995. Children with asphyxiating FB aspiration, requiring
immediate rigid bronchoscopy, were excluded. If there was clear evidence of
FB aspiration from the physical and radiographic findings, rigid
bronchoscopy was directly performed. If the evidence was not convincing,
children underwent diagnostic flexible bronchoscopy under local anesthesia.
If an FB was found, rigid bronchoscopy was always performed for extraction.
Eighty-three consecutive children (median age: 24 mo) were included. Among
28 who underwent rigid bronchoscopy first, 23 had an FB. Among the 55
children who underwent flexible bronchoscopy first, 17 had an FB.
Predictive signs of a bronchial FB were a radiopaque FB, and associated
unilaterally decreased breath sounds and obstructive emphysema (positive
predictive value = 0.94). We propose the following management algorithm:
Rigid bronchoscopy is performed first in case of asphyxia, a radiopaque FB,
or association of unilaterally decreased breath sounds and obstructive
emphysema. In any other case, flexible bronchoscopy is performed first for
diagnostic purposes. If applied retrospectively to the 83 children in our
study, this algorithm would have decreased the negative first rigid
bronchoscopy rate to 4%. Flexible bronchoscopy is a safe and cost-saving
diagnostic procedure in children with suspected FB aspiration.
