Summary
Knee arthroscopy using a continuous pressure-irrigation system with prilocaine-saline solution is safe and effective. This method offers high diagnostic accuracy for knee derangements with minimal prilocaine absorption and no adverse effects.
Area of Science:
- Orthopedic Surgery
- Anesthesiology
Background:
- Knee arthroscopy is a common procedure for diagnosing knee derangements.
- Local anesthesia and irrigation systems are crucial for patient comfort and procedural success.
Purpose of the Study:
- To evaluate the safety and efficacy of a continuous pressure-irrigation system using 0.2% prilocaine-saline for knee arthroscopy.
- To assess the diagnostic accuracy and patient tolerance of the procedure.
Main Methods:
- 174 patients with knee derangements underwent arthroscopy under local anesthesia.
- A continuous pressure-irrigation system with 0.2% prilocaine-saline was employed.
- Serum prilocaine levels were monitored in 19 patients for six hours.
Main Results:
- The pressure-irrigation system provided excellent knee distension, leading to high diagnostic accuracy.
- All patients tolerated the procedure well, with no reported adverse side-effects.
- Mean peak serum prilocaine levels were low (0.28 µg/mL) at one hour, indicating minimal systemic absorption.
Conclusions:
- Continuous pressure-irrigation with 0.2% prilocaine-saline is a safe and efficient technique for knee arthroscopy.
- This method meets the growing demand for arthroscopic knee procedures effectively.
- The technique ensures high diagnostic yield and patient safety.
