Iatrogenic tracheobronchial perforation in infants
Insights
Iatrogenic tracheobronchial perforation from endotracheal tube placement is a rare but serious complication in premature infants. Early recognition of malposition and pneumomediastinum on radiographs is crucial for prompt management and improved survival rates.
Area of Science:
- Pediatric critical care
- Neonatology
- Medical device complications
Background:
- Endotracheal tube (ETT) placement is a common procedure in neonates.
- Iatrogenic tracheobronchial perforation is a rare but life-threatening complication.
- Premature infants are particularly vulnerable due to their delicate airway anatomy.
Purpose of the Study:
- To describe the clinical and radiographic features of acute iatrogenic tracheobronchial perforation in premature infants.
- To highlight the importance of early recognition and prompt management.
- To review previously reported cases and assess overall mortality.
Main Methods:
- Retrospective review of four premature infants with confirmed tracheobronchial perforation.
- Analysis of clinical presentation, intubation details, and radiographic findings.
- Comparison with eight previously reported cases.
Main Results:
- Four cases of iatrogenic tracheobronchial perforation due to ETT malposition were identified.
- Radiographic findings included inferior ETT malposition, decreased pulmonary aeration, and pneumomediastinum.
- Two infants died despite aggressive management; two survived with conservative care.
- Overall mortality in reported cases is 58%.
Conclusions:
- Acute iatrogenic tracheobronchial perforation is a significant risk in premature infants undergoing intubation.
- Subtle radiographic signs, including infraazygos pneumomediastinum, should raise suspicion.
- Prompt recognition and appropriate management are critical for improving outcomes and potentially saving lives.
Abstract:
We describe the clinical and radiographic features of four premature infants with acute iatrogenic tracheobronchial perforation by endotracheal tube (ETT) placement. One tube penetrated posteriorly into the esophagus, one directly through the carina; one perforated the right main bronchus posteriorly; and one breached the site of a recently repaired tracheoesophageal fistula. In only one infant was the intubation procedure clinically recognized to be traumatic. Radiographs obtained for tube placement demonstrated inferior malposition of the ETT in all four babies, decreased pulmonary aeration in three of four, acute retrocardiac infraazygos pneumomediastinum in three of four, and acute pleural effusion in one of four. Two infants developed progressive air leak and died in spite of drainage with multiple chest tubes; two survived and did well with conservative management. An additional eight cases have been previously reported, with an overall mortality of 58%. Prompt recognition of acute airway perforation can be lifesaving. Unexpected respiratory distress after intubation associated with acute infraazygos pneumomediastinum strongly suggests this entity.
