Airway anomalies in newborn infants: detection by tracheoscopy via endotracheal tube

Area of Science:

• Pediatric Pulmonology
• Neonatal Intensive Care
• Medical Device Technology

Background:

• Artificial ventilation is crucial for neonates with respiratory distress.
• Airway complications can arise during mechanical ventilation in infants.
• Early detection of airway anomalies is essential for effective respiratory support.

Purpose of the Study:

• To evaluate the utility of an ultrathin flexible fiberscope for diagnosing airway anomalies in infants.
• To assess the feasibility of maintaining artificial ventilation during fiberoptic examination.
• To determine the effectiveness of bedside fiberoptic assessment for managing ventilation problems.

Main Methods:

• Utilized an ultrathin flexible fiberscope (Olympus PF18 S, 1.8 mm) in 24 infants (27-40 weeks gestation).
• Introduced the fiberscope via a modified four-way T-adapter to enable uninterrupted ventilation.
• Performed bedside assessments to identify structural airway anomalies and ventilation issues.

Main Results:

• Detected acquired and congenital structural airway anomalies in 6 out of 24 infants (25%).
• Successfully maintained artificial ventilation, including oxygen flow and positive pressure, during fiberoptic intubation.
• Quickly identified tube position, mucus accumulation, and partial tube obstruction at the bedside.

Conclusions:

• Ultrathin flexible fiberoptic bronchoscopy is a valuable tool for diagnosing infant airway anomalies.
• The described method allows for safe and continuous artificial ventilation during airway examination.
• Bedside fiberoptic assessment facilitates rapid diagnosis and management of ventilation problems in neonates.
