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

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.

Detailed Summary:
Sponsor: Charite University, Berlin, Germany

Current Primary Outcome: NRS reduction during therapy [ Time Frame: 2 weeks ]

Reduction (relative and absolute) of pain during series of infiltrations comparing NRS scores before and after infiltrations


Original Primary Outcome: Same as current

Current Secondary Outcome:

  • Number of blocks in a series [ Time Frame: 4 weeks ]
    Number of blocks in a series to achieve the targeted NRS reduction
  • Time till recurrent pain [ Time Frame: 24 weeks ]
    Time until a new series of blocks is requested by the patient
  • clinical course of pain [ Time Frame: 2 weeks ]
    NRS development during series of infiltrations
  • type of infiltration [ Time Frame: 2 weeks ]
    location of infiltrations with medication used
  • co-parameters of pain chronification [ Time Frame: 2 weeks ]
    co-factors of pain like co-morbidity, duration of pain disease, psychological diseases and association with primary outcome


Original Secondary Outcome: Same as current
