Insights
Routine chest radiography after pediatric tracheostomy is rarely necessary. A low incidence of air-tracking complications suggests reserving imaging for clinically suspected cases, reducing radiation exposure and costs.
Area of Science:
- Pediatric Surgery
- Thoracic Imaging
- Critical Care Medicine
Background:
- Routine chest radiography is standard post-pediatric tracheostomy to detect air-tracking complications.
- This practice exposes children to unnecessary radiation and incurs significant costs.
Observation:
- A retrospective study analyzed 421 pediatric patients undergoing tracheostomy.
- Data were collected from billing, administrative systems, and electronic medical records.
Findings:
- The incidence of air-tracking complications (pneumothorax, pneumomediastinum) was very low at 0.71%.
- No correlation was found between complications and surgical specialty, patient age, or procedure type.
- Clinical suspicion, not routine imaging, identified all three identified complications.
Implications:
- Postoperative chest radiography following pediatric tracheostomy should be reserved for patients with clinical suspicion of complications.
- This approach can minimize radiation exposure and healthcare costs in pediatric patients.
- Further research could explore specific clinical indicators for targeted imaging.
Objectives:
Routine chest radiography following pediatric tracheostomy is commonly performed in order to evaluate for air-tracking complications. Routine chest radiography affords disadvantages of radiation exposure and cost. The primary objective of this study was to determine the utility of routine postoperative chest radiography following tracheostomy in pediatric patients. Secondary objectives were to compare the rates of postoperative complications by various patient and surgeon characteristics.
Methods:
All infants and children 18 years of age or less (n=421) who underwent tracheostomy at a single tertiary-care medical center from January 2000 to April 2009 were included in the study. A combination of data obtained from billing and administrative systems and review of electronic medical records were recorded and compiled in a database for statistical analysis.
Results:
Three air-tracking complications (2 pneumothoraces and 1 pneumomediastinum) were identified in our population of 421 pediatric patients, for an incidence of 0.71% (95% CI: 0.1-2.0%). No significant relationships were found between the incidence of air-tracking complication and surgical specialty, patient age, or type of procedure (elective, urgent/emergent).
Conclusions:
Our study identified a low rate of pneumothorax and pneumomediastinum following pediatric tracheostomy. In all three cases, the pneumothorax was suspected clinically. This finding suggests that postoperative chest radiography should be reserved for cases where there is suspicion of a complication on the basis of intraoperative findings or clinical parameters.

Bronchoscopy
Description
Bronchoscopy is a procedure that involves direct visualization of the larynx, trachea, and bronchi for diagnostic and therapeutic purposes. A flexible fiber optic or rigid bronchoscope is used to carry out the procedure. The fiber-optic bronchoscope is more frequently used due to...
