Summary
Bismuth subgallate aids clotting but can cause respiratory issues if aspirated during tonsillectomy. Surgeons should be aware of these potential pulmonary complications in pediatric patients.
Area of Science:
- Otolaryngology
- Pulmonology
- Pediatric Surgery
Background:
- Bismuth subgallate is used to control bleeding during tonsillectomy and adenoidectomy.
- It functions by activating factor XII to initiate clotting.
- Previous studies noted pulmonary complications in animals but not humans.
Observation:
- Two pediatric cases of bismuth subgallate aspiration after tonsillectomy and adenoidectomy are presented.
- Patients experienced significant respiratory difficulty.
- Neither case required airway intubation.
Findings:
- Aspiration of bismuth subgallate can lead to acute pulmonary complications.
- Clinical presentation included respiratory distress post-operatively.
- The severity of complications did not necessitate mechanical ventilation in these cases.
Implications:
- Surgeons must consider the risk of bismuth subgallate aspiration.
- Awareness of potential airway problems is crucial when using this hemostatic agent.
- This highlights the need for careful technique during pediatric tonsillectomies.
