Regional Anesthesia in Refractory Trigeminal Neuralgia: 21 Cases Reported to the Limoges University Hospital (TRINEB ONE)
September 24, 2019 updated by: University Hospital, Limoges
Trigeminal neuralgia is defined according to the third edition of the International Classification of Headache Disorders (ICHD-3) criteria.
Chronic pain can have a major impact on the quality of life.
First-line treatments are anti-epileptics, and surgical treatments are also possible according to several approaches.
Sometimes the pain is resistant to these therapies.
In this indication, sensory blocks may have a therapeutic impact but their place is not clear.
In France, there are formalized expert recommendations on "loco regional analgesia and chronic pain", from 2013.
Several adjuvants to local anesthetics have been studied for acute and chronic pain.
CLONIDINE and DEXAMETHASONE are of greatest interest in increasing block duration and reducing opioid consumption.
The investigators report the case of 21 patients, treated by a trigeminal block from 2014 to 2018, suffering from a resistant trigeminal neuralgia.
After a first consultation, the diagnosis is confirmed, an information is done and an appropriate support is established.
The sensory block is performed as an outpatient care.
It consists in a peri-neural injection of a mixture of LEVOBUPIVACAINE 5%, CORTIVAZOL 3.75mg / 1.5mL (or BETAMETHASONE 7mg / 1ml) and CLONIDINE (1μg / kg).
Standard precautions are respected and patients are monitored in the recovery room after the procedure.
The efficacity is evaluated before the exit and a follow-up is done within 15 days.
The level of satisfaction expressed by the patients seems to be globally high.
The investigators wish to evaluate statistically the impact of the trigeminal blocks, in terms of improvement of the quality of life.
This retrospective study, by its procedure, does not change the management of patients.

Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change of the quality of life from baseline to day 15 after baseline
Time Frame: Day 0, Day 15
|
Percentage of patients with improvement of more than 50% in quality of life, mesured with the 'Medical Outcome Study Short Form 12', from baseline (day 0 = just before the block) to day 15.
The questionnaire consists of 12 items questioned weighted and summed to provide physical and mental health scores (PCS and MCS).
The two composite scores are computed using the scores on twelve questions that range from 0 to 100, with higher score indicating better health.

Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Change in pain level just before and after the block assessed by a numerical scoring scale
Time Frame: Day 0, Day 15
|
Average value of the Numerical Rating Scale immediately before, after and at day 15 after the block.
Zero represents 'no pain at all' whereas ten represents 'the worst pain ever possible'
|
Day 0, Day 15
|
Neuropathic criteria of pain just before and after the block assessed by DN4
Time Frame: Day 0
|
Average value of the DN4 score before and after the block.
DN4 questionnaire helps estimate the likelihood of neuropathic pain.
The maximum score is 10.
The threshold value for the diagnosis of neuropathic pain is 4.

|
Patient overall satisfaction assessed by a Numerical Rating Scale.
Time Frame: Day 0
|
Average value of the Numerical Rating Scale.
Zero represents 'not at all satisfied' whereas ten represents 'very satisfied'.
