NCT01635205

Brief Summary

This study examines randomized triple-blind clinical trial and the efficacy of paraspinous anesthetic block on the treatment of chronic pelvic pain in patients non-responsive to pharmacological management. Sixty patients will be randomly divided and allocated into group intervention (paraspinous anesthetic block) and control (placebo procedure in subcutaneous tissue).

Outcome Measures

Primary Outcomes (1)

  • Change of pain from baseline

    Primary outcome is the reduction of pain, measured with the Visual Analogue Scale (VAS).

    Change of pain from baseline at one week, at one month, at two months, at three months, at four months, at five months and at six months

Secondary Outcomes (2)

  • Improvement of scores in SF-36 scale

    At baseline and at six months

  • Improvement of scores in the FSFI scale

    At baseline and at six months

Study Arms (2)

paraspinous block

EXPERIMENTAL

Procedure: paraspinous anesthetic block

control

SHAM COMPARATOR

Subcutaneous puncture with no anesthetic effect

Procedure: subcutaneous puncture with no anesthetic effect

Interventions

paraspinous block

Subcutaneous puncture with injection needle (no substance will be injected)

control

Eligibility Criteria

Age18 Years+
Sexfemale
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Patients with benign pelvic pain non-responsive to pharmacological treatment, lasting at least 6 months, located in the anatomic pelvis, anterior abdominal wall, infra-umbilical region, lumbossacral region or buttocks. Pain must be hard enough to cause functional impairment or to motivate medical counseling. The absence of physical findings does not decreases the importance of pain, nether excludes the possibility of pelvic pathology.

You may not qualify if:

  • Patients who do not want to take part in the study
  • Age under 18 years old
  • Pelvic pain lasting less than 6 months
  • Relief or resolution of pain with pharmacological treatment
  • Pain of neoplastic origin
  • Known allergy or report of adverse reaction related to lidocaine
