Summary
This study presents a novel microsurgical pediatric tracheotomy model in growing rats. This feasible technique allows for long-term research into pediatric airway management and surgical outcomes.
Area of Science:
- Veterinary Surgery
- Pediatric Airway Management
- Microsurgery
Background:
- Controversies exist regarding pediatric tracheotomy techniques and long-term outcomes.
- Experimental studies on rat tracheas are limited due to technical challenges with small anatomical structures.
Purpose of the Study:
- To develop a microsurgical pediatric tracheotomy model in growing rats.
- To facilitate long-term studies on the repercussions of pediatric tracheotomy.
Main Methods:
- Forty-four Wistar rats underwent tracheotomy using longitudinal incision, transverse incision, or segment excision.
- A custom endotracheal cannula was created from silicone catheter and silicone screen.
- Procedures were performed under sterile technique with ketamine/xylazine anesthesia.
Main Results:
- A feasible microsurgical pediatric tracheotomy model was successfully established in growing rats.
- The model allowed for the insertion of a custom-designed endotracheal cannula.
- Post-operative evaluations included body weight, secretions, and dehiscence after 7 days.
Conclusions:
- The developed microsurgical technique provides a viable model for pediatric tracheotomy research in rats.
- This model enables long-term investigation into the effects and outcomes of pediatric tracheotomy.
