Initial Assessment:
Signs of impending respiratory failure: Reduced level of consciousness or lethargy Quiet, shallow breathing Apnea
The above require immediate progression to endoscopy and/or intubation.
4
History:
Description of OnsetAge at onsetHistory of foreign body aspiration/ingestionAggravating factors: feeding/sleepingHistory of intubationBirth history (syndromes, birth trauma)
6
Flexible Laryngoscopy:
Proper EquipmentAssess nares/choanaeAssess adenoid and
lingual tonsilAssess TVC mobilityAssess laryngeal
structures
7
Radiology:
Plain films: Chest and airway AP and
lateral Expiratory films High vs. low kilovoltage
FluoroscopyBarium SwallowCT, MRI, Angiography
8
Flexible Bronchoscopy:
Does not require general anasthesiaMainly diagnostic purposesLimited intervention (e.g. suctioning)Can be used for intubationLimited airway control
9
Direct Laryngoscopy andRigid Bronchoscopy
Indications: Severe or progressive airway obstruction No diagnosis after flexible laryngoscopy and
radiology Subglottic pathology suspected
Advantages over flexible bronchoscopy: Better control of the airway
12
The Ventilating Bronchoscope
A. Light source and telescopeB. Prismatic light detector and
attachment to light sourceC. Aspiration and
instrumentation channelD. Connector to anesthesiaE. Telescope bridge
14
Rigid Bronchoscopy:
Complications: Loss of airway control Injury to subglottic space Damage to teeth or gums Airway bleeding Pneumothorax Failure to recognize pathology

Case Study: History
Consult from the Neonatal ICU: Newborn infant in increasing respiratory
distress since birth. Oxygen saturation is now 100%, but the child
has begun to use accessory muscles. Feeding aggravates the distress. Infant has a weak cry, and pediatritians notice
noisy breathing. No abnormal birth history.

Case Study: Physical Examination
Newborn female infant supine in the bed, sat’ing 100% on room air
Moderate use of accessory musclesModerate biphasic stridorAudible breaths through both naresRepositioning has little effect on stridor
