Regional-anaesthesiological Infiltration Techniques for the Management of Chronic Pain: a Retrospective Study

Completed

• Conditions: Cluster Headache; Post Zoster Pain; Neuropathic Pain; Trigeminal Neuralgia; Post-Zoster Neuralgia; Chronic Pain

• Registration Number: NCT03066037
• Lead Sponsor: Charite University, Berlin, Germany

Brief Summary

There is a significant debate whether local infiltration techniques may be a method to treat complicated chronic pain syndromes, e.g. refractory headache. Until now there is a lack of evidence regarding efficacy of this treatment especially in long term follow up. Similarly, indication and management are under debate. Aim of this trial is to analyse pain scores during first treatment with anaesthesiological infiltration series.
