Summary
This study demonstrates a feasible rat model for isolated single lung perfusion, crucial for studying chemotherapy delivery. The technique showed low mortality, supporting its use in preclinical research.
Area of Science:
- Thoracic Surgery
- Surgical Innovation
- Preclinical Research Models
Background:
- Isolated lung perfusion (ILP) is a promising technique for targeted lung treatments.
- Developing a reliable animal model is essential for evaluating ILP efficacy and safety.
- Previous models have limitations in reproducibility and applicability to complex studies.
Purpose of the Study:
- To establish and validate a rat model for in vivo isolated single lung perfusion.
- To assess the feasibility and safety of this technique in a preclinical setting.
- To provide a platform for future studies on isolated lung chemotherapy delivery.
Main Methods:
- Anesthetized rats underwent left thoracotomy and microscopic visualization.
- The left pulmonary artery was cannulated, and a venotomy was performed for perfusion.
- Isolated left lung perfusion was conducted using heparinized whole blood or saline.
Main Results:
- The in vivo isolated single lung perfusion procedure had a high survival rate (95%).
- Subsequent right pneumonectomy also showed good survival (78%).
- Surgical survivors regained preoperative body weight, indicating successful recovery.
Conclusions:
- In vivo isolated single lung perfusion in rats is a feasible technique with low mortality and morbidity.
- This model serves as a valuable tool for investigating isolated lung chemotherapy and other physiological experiments.
- The established model supports further research into targeted lung therapies.
