Évaluation d'un schéma thérapeutique d'analgésie loco-régionale pour les algies chroniques de la face

Abstract : Background: Up to date, regional analgesia is indicated in chronic facial pain management. Objective: To describe a significant decrease of pain score, evaluated by Numerical Rating Scale (NRS), of at least 2 points in chronic facial pain between day 0 and day 21 for patients who underwent a regional analgesia standardized protocol during this period. Methods: This study (an audit) was conducted in two steps. The first one consisted in inclusion of patients who underwent trigeminal nerve blocks between 2010 and 2014 in the University Hospital Center of Bordeaux. After that, a follow-up step was launched by using a standardized phone assessment. Blocks were weekly performed using Levobupivacaine and corticosteroids. Four successives blocks defined a cluster. Those last could be repeated, depending on pain evolution. Parameters that have been collected at inclusion were NRS, treatments, and invasive procedures already undertaken. Primary outcome was variation of pain between D0 and D21 for the first cluster C1. Secondary endpoints were variation of NRS between D0 and D21 for each cluster, then quality of life, treatments and NRS remotely evaluated during phone survey. Qualitative data are set as proportion and quantitative one as median [IQR 25%-75%] or n according to parameters. Results: Forty-four patients were analyzed. The NRS at D0 and D21 of C1 are 8 [6-9] and 4 [2-7] (p <0.001) respectively. The first three clusters record a significant difference in pain relief between D0 and D21 (p <0.05). In march 2014, after a free range of 15 months [4,25-24] since the last block, 33 people answered to the phone survey. We reported an improvement of quality of life (82%), decreased analgesics consumption (57%) and NRS was 4 [2-6]. Conclusion: Our study strongly emphasize the interest of regional analgesia in the management of chronic facial pain.
