Suprascapular catheter migration occurred in 25% of cases after simulated physiotherapy in a cadaver model. This suggests potential dislodgement during shoulder manipulation, requiring further clinical investigation for continuous peripheral nerve blocks.
Area of Science:
- Anesthesiology
- Pain Management
- Anatomy
Background:
- Continuous peripheral nerve blocks are vital for pain management.
- Catheter dislodgement or migration incidence is often underestimated.
- Suprascapular catheter positioning requires assessment during physiotherapy.
Purpose of the Study:
- To evaluate suprascapular catheter tip positioning.
- To assess catheter migration after simulated shoulder physiotherapy.
- To utilize an anatomical cadaver model for accurate analysis.
Main Methods:
- Eight ultrasound-guided suprascapular nerve block catheters were placed in cadavers.
- Computed tomography (CT) confirmed initial catheter tip placement.
- Simulated physiotherapy and subsequent dissection identified post-manipulation positions.
Main Results:
- CT confirmed initial catheter tips at the suprascapular notch.
- Two out of eight catheters (25%) migrated after simulated physiotherapy.
- Migrated catheters were found in the supraspinatus and trapezius muscles.
Conclusions:
- Catheter dislodgement may occur in approximately 25% of cases post-physiotherapy.
- Findings highlight a potential risk of suprascapular catheter migration.
- Further clinical research is necessary to confirm incidence in practice.
